Dual monitors with Display port

Q: Dual monitors with Display port

I have an up-to-date computer built to run games very well. I want to use two monitors. They're both TVs that support being used as a monitor. The first one is the one I've been using since I bought the computer, connected via HDMI converted to DVI(i believe. not VGA, but still gets fastened by one screw on each side). The other, new TV that I bought, I am trying to connect via HDMI converted to DisplayPort, and nothing is registering or being found/detected

I need to convert to dual monitors on a HP 6200 Pro MT PC with Display Port and VGA ports.  The computer displays propertly with a single monitor connected to the VGA port.  Both monitors go black when I plug in a second monitor via the Display Port. In reading Internet documentation it is not clear if dual monitors will function from the system Display Port and VGA ports.  Forum articles address dual monitors with addition of a discrete video card (Big_Dave 2/4/2012). Will dual monitors work from the system Display Port and VGA ports?  If yes, what procedures are required to make such configuration work?  Any ideas on why the monitors go black?  Is a discrete video card required? Any assistance would be much apprecited as I ususally prepare income taxes and do not deal with bytes and bits.

I have a Dell Vostro with one monitor output port. I'd like to get an adapter(splitter?) to plug two monitors into that will then plug into that one graphics card. Doing office stuff - word processing, excel, etc., - nothing graphically challenging.

I own a Lattitude E7450, and needed to connected two displays to it. I went ahead and bought the Dell E-Port Plus Advanced Port Replicator with USB 3.0, since it has 2 DVI ports on the back. It shows it is compatible with my laptop.
I set up my dock, connected my laptop, as well as both external monitors. Only one monitor shows a duplicated desktop. When I go into the display settings, I cannot see any existence of another external display being connected.
All of my drivers are up to date, restarted laptop many times. Pretty bummed out.

Hi,
So this is the first time this sort of thing has ever happened. When I turned on my PC today only one monitor was picking up signal. In attempt to fix this I switched the display ports from the working monitor to the non working monitor. Nothing happened so I moved the cables back, when I did that the other monitor no longer received signal. I then plugged in a hdmi cable to my monitor and still no signal. I then unplugged the power to the PC and held the on/off button for 60 seconds and re plugged the power. The monitor began receiving signal but only through hdmi and the other monitor still does not work.
I have no idea how to fix this. Any help would be appreciated.

Hello everyone, My client purchased a new ProDesk 400 G3 to replace a defected one that they got. Everything was going fine with the replacement until I noticed that everytime you reboot the PC. The 2nd monitor turns off and when you login as a domain user. You have to manually detect the monitor in the Intel management concole. For somereason either Windows or the driver forgets when you reboot but I'm thinking it's drivers. I installed 7 other same model ProDesk's and right out of the box with the drivers and image already installed. When you plugin a scond monitor Windows won't recognize the 2nd display. I figured it out though, you have reinstalling the intel display driver and then both displays will work. But this isn't working for the PC that I'm talking about because it resets after you reboot. I tried uninstalling the driver and reinstalling it a bunch of times. I'm almost certain that it's a driver issue because the other PC's had issues with their displays as well. Intel doesn't seem to have a updated driver out yet either so I hope that this PC isn't not deffected like the last because it's going to look bad on me when it's HP's fault. If anyone has any intelligant ideas and not repeating steps that I have already tried. I would greatly appreciate it. Thanks,Scott K

I have two U2715H monitors connected via one mDP->DP cable each to an E-Port Plus docking station (actually a EURO2 Advanced Port Replicator) in which is seated a Latitude E7450 laptop. All items are brand new. The E7450 is equipped with 16 GB RAM and two graphics cards: Intel HD Graphics 5500 and NVIDIA GeForce 840M; selection is automatic, which usually means the 5500 is in operation. It runs Windows 7 Enterprise SP1 (64 bit). The docking station apparently has DP 1.2a capabilities (for daisy chaining) but DP 1.2 is disabled in both monitors.
I have successfully set up the system to have the Windows desktop span both monitors at 2560x1440 resolution, even with the Latitude's internal screen as a third extension at its full resolution (1920x1080). The Main display may be set to either of the two (or three) and I can successfully move the sequence of the monitors around (left, middle, right).
So there is no doubt about the system's capability to support the intended configuration. However, when I dock the Latitude (mostly with the lid shut) and boot it, most of the time it cannot reestablish the configuration of the two external monitors. Some of the symptoms are: One or both monitors go black, indicating cable connected but no signal arriving from the docking station. If there is a picture on one of the monitors at startup, it may or may not contain the login screen. (I can still log in because I know what keystrokes to send.) If the login screen is visible, ...

A:Latitude E7450, E-port 2, U2715H - dual monitors - unstable configuration

No responses, so I will add my own, on the way towards a solution, which I believe requires driver enhancements. Are you listening, Dell?
Together with a colleague who knows better than me what to look for, we discovered:- The Intel HD graphics control panel -> Display port topology only discovers one, not two display ports. This could be a problem with the panel or with the graphics driver.- Both Intel and Nvidia have more recent driver releases for their respective hardware components in the Latitude E7450 than those available from Dell but they cannot be installed directly. (NVidia 353.06 vs 341.27; Intel 10.18.10.4222 vs 10.18.14.4099 - I suspect digits 5 and 6 reflect an OEM numbering scheme). Intel says their driver update includes critical fixes for display support.- When we attempted to install the latest Nvidia driver, the display flashed in what seemed to be a non-trivial manner (before the update was automatically aborted). This could be related to a conflict between the two drivers.
I also discovered that even when only one of the Dell U2715H monitors is connected, it frequently goes black when it shouldn't. So it is not a question of a dual monitor configuration as I originally thought. I have also swapped docking stations to eliminate random hardware error in this component. The Intel driver's handling of display port(s) seems to be the most likely culprit.
Guessing from seeing repeated patterns of monitor behavior, a more precise diagnosis could be t... Read more

Since it is a generic video card I cannot find where to set up the monitor to view seperate utilities/programs. Any suggestions?

A:dual monitors not showing up in display

exactly what video card? sounds like you need to install vista drivers for it. If t came with the system, you should be able to go to the computer manufacturers and get the proper drivers. If you purchased it separately, go to the video cards manufacturers website and get the driver there.

Normally for dual monitors all you have to do is to right click desktop, click on properties, and click on settings.

I have a Dell Latitude E7450 laptop with a E-Port Plus II port replicator connected to two external monitors using DisplayPort which will not output to multiple monitors.
I have another Dell model and when placed on the port replicator with two external monitors connected, booting into BIOS/UEFI the screen is cloned onto each monitor. However, when doing the same with a brand new Dell Latitude E7450 only one screen is active - the other is off. Within Windows itself, I can only have 1 monitor connected to the port replicator. If I undock, I can run 3 monitors independently indicating an issue with the dock rather than a hardware limitation with the laptop itself.
I believe the above tests eliminates the OS or driver issue and highlights a compatibility issue between the new Dell Latitude E7450 laptop and E-Port Plus II port replicator. I have tried this on 2 separate machines with the same results. I have also updated both the graphics drivers (Version 10.18.14.4170, A16) and the BIOS (Version A04) to the latest releases. I have also tried using DVI cables as well as swapping out the port replicators. Nothing works. In Windows 8.1 itself, it actually shows as two monitors active, but one is not on. If I swap out the monitors to a different brand, I get the same result.
Is there a BIOS/UEFI setting I need to change? Is there a newer port replicator or update I need?

A:Setting up dual monitors for extended display - ne...

That's not really how you run two monitors in "extended desktop" mode.  You are using a setup that is intended to provide identical output onto two monitors out of a single video card port.  This is actually equivalent to running "clone mode" from a video card that contains two ports to feed two monitors individually.
 
What you really want is simply a multi-port graphics card installed in your M91p, which provides connectivity to two monitors simultaneously from its two ports.  Then you can use the video card's drivers and/or Windows to configure your two connected monitors to run either in (a) clone mode, with identical output to both monitors, or (b) extended desktop mode, which spreads the Windows desktop "double-wide" to use the full horizontal expanse of both monitors so that you can drag windows back and forth across both.
 
I would suggest a very modesly priced ASUS Silence (fanless) HD6450 card, which includes both full-size and low-profile brackets in the retail box. So you can use it in either a tower or small-form-factor case.  Note that the VGA connector is available on the full-size bracket, so if you use the low-profile bracket in a SFF case you will only have the remaining two DVI and HDMI connectors.  If you have to connect to a monitor that only supports VGA, you'll have to use an adapter.  But if you have the option of a digital connection on both your monitors, then both the low-profile and full-size brackets will al...

I just bought a Samsung 4K monitor and would like to up scale the display so I can see it. I also have an HP 1920x1200 monitor. The problem is that when I scale the dpi it affects both monitors, which is not at all satisfactory on the HP. So far the best solution I've found is to set the 4K to 2560x1440, but that seems like a waste to me. Is there anyway to set different dpi for each monitor.

Another solution I thought of was to use the HP as my primary monitor. The problem with this is that the steam games I play don't seem to allow running on monitor 2.

Thanks for any thoughts.

A:Scaling monitor display with dual monitors

You get use to it. Scaling the DPI can also effect some applications that use Windows DPI settings so be careful. When you push it beyond 120% some application menus will be offset. (The actual menu will remain in the same place but the area in which you click would of shifted). This will also happen in some games that use Windows DPI settings and not their own. The game itself looks fine until you attempt to use the menu system. I know of two games that are affected by Windows DPI, EVE Online and Mass Effect.

Firefox has a scale feature that you can use by pressing and holding Ctrl + MouseScroll.

A:i have a dual monitor display and want sound from both monitors

I don't think you can do what you want, with the setup you have. First, Windows only allows one "default" audio playback device and with HDMI it defaults to the HDMI audio. Thus the PC audio (speakers) do not work.

I don't know if an external device would split the HDMI audio so you could do what you want. That looks like the option if something like that is available.

Hey everyone, I've been having a recent issue with my monitors and it's really been stumping me lately. I recently acquired a 2nd Yamakasi 2560x1440 monitor from South Korea (I love these things!) and while the monitors themselves are working quite well, I've been having an issue since I connected the 2nd one.

Occasionally (maybe 25-50% of the time) when the PC has been idle for long enough that the monitors have turned off, when I come back to the PC and move the mouse or press a key on the keyboard, the monitors turn back on and I am promptly greeted with a black screen on both, however it appears that there IS a signal as the monitors turn on and remain on, however that signal is just a blank black screen. I've got both monitors beside each other, and the one on the left side is plugged directly into the dual link DVI port on the back of my master 7950 in my crossfire configuration. The right-side monitor is plugged into an active displayport to dual link DVI adapter, which also requires a USB port for power.

When I notice this black screen effect, I also notice a small, thin blueish bar spanning the height of the right monitor, at the far right side of the screen; this bar looks about the same thickness as the side edge of an open window in Windows 8, but I've never been able to tell if that's what it is or not.
UPDATE: Upon closer inspection of the "blue bar", I can now tell that it doesn't look quite the same as the Windo... Read more

A:Dual monitors occasionally won't display anything after PC is idle

Update: I've discovered that usually the problem can be solved by unplugging and replugging the displayport adapter while the PC is on, but only if the aforementioned "blue line" is present on the right-hand screen when I move the mouse. Yesterday, I had a similar issue except that instead of turning back on and detecting the PC's video signal which is just a black screen for both of them (with blue bar on the right one), the monitors (both of them) refused to even acknowledge that there was a signal coming to them at all and wouldn't even turn their backlights on or wake from sleep mode. Even when I hooked up 2 different monitors using standard DVI-D single link or dual link cables, I still could not get any video signal to output at all, to ANY monitor.

Turning my speakers on, I found that I could hear the Windows 8 "device connect" and "device disconnect" sounds when I unplugged or replugged either of my 27" monitors, but nothing at all was heard when attempting to switch to other monitors. This tells me that Windows IS detecting and seeing the monitors, but somehow the video signal is just not reinitializing properly after the computer turns the monitors off after idle time.

The only solutions I've got at the moment are to set Windows to NEVER turn my monitors off, or to shut down the PC every single time I'm done with it; neither of these solutions are particularly pleasing to me. Please let me know if anyon... Read more

I recently installed a second monitor for my PC. I have an AMD 7850 and one display is a DVI output (my primary and previously used display) and the new one uses an hdmi output. When I first tried this, it worked completely fine but now, when I boot to windows the computer doesn't output a display when both are connected.

The computer is booting to windows succesfully, though, as the num lock key works and I can shut down the computer with out hard killing the power. If I boot with only the DVI monitor everything is fine and, after I have booted to windows, I can then connect the hdmi and both displays work.

Any ideas as to why this might be happening? Is there some way to choose a primary display port on the video card? Thanks for the help.

Hello, everyone.
I am using a Latitude 3540 laptop with switchable graphics (Intel HD Graphics, AMD Radeon HD 8850M). As soon as I got the laptop, I upgraded to 8.1 (probably a mistake!).
All of my drivers are up to date according to Device Manager, and I've updated the chipset and BIOS and everything according to the Dell website. But for as long as I've had this laptop, the VGA port will not work! I'm using a VGA cord that has worked with other laptops before without issue. The laptop will not output to projector, external monitor, or a TV. Pressing the win-P combination brings up the ability to extend and duplicate my screen. When I change those settings, my screen resolution will change, but the external monitor/projector doesn't display anything. When I try to detect displays in my graphics properties, it just doesn't detect anything that's connected.
Is my VGA port faulty? Or does anyone have any suggestions on what else to try at this point? My laptop is still under warranty, so I suppose I could always send it in to be fixed.
Thanks for the help!

So I recently got a second monitor so I can work with two screens at once. As I kind of expected, I had to calibrate the monitors so their colors, brightness and all everything else match each other. But how much I may try, I can't manage to calibrate them properly. Worse, both monitors seem to be calibrated from tests, yet they still don't match.

It's hard to explain what the differences are, so I included pictures of them in the attachments. Take in mind that they're photo's from my phone, since screenshots obviously wouldn't work.

The first one, monitorDifference_blackgrayOnSteam.jpg, is made by placing the steam client over the two screens. The left side is from the new monitor, which seems to be more dark green, and the right side is the old monitor, which seems to be more light grey.

The second one are monitorDifference_foxOld.jpg (old screen) and monitorDifference_foxNew.jpg (new screen), which are from with a wallpaper. The old one seems to be more dull and brighter while the new one seems to be more colorful/warmer (?) and darker.

Just for the sake of having enough information, the old monitor is an Asus VH222H which I have for almost two years, and the new one is a LG Flatron IPS224, which is just a few days old.

These differences aren't everywhere or not as noticeable, but there are plenty things like the above two examples where the differences are big and annoying. So the question is, how can I fix this difference problem and make the monitors match properly... Read more

A:Dual monitors aren't showing the same colors/display

Are you using the sRGB colour profiles on both monitors?

It could be simply down to the age of the monitors - you probably didn't notice the changes with your old one until you hooked up your new one along side it. You might need to set the colour/brightness/contrast/temperature settings individually on one or both monitors to compensate for this.

I am running Windows 7 RC Build 7100 in VMWare 6.5. The host OS is Vista x64 Home Premium running on a Dell Studio 1535. I have a Dell monitor attached as a secondary monitor, and I am attempting to share the desktop across both monitors. While I can do that, Windows 7 insists on using the external monitor as the primary monitor, and if I attempt to change the main display to the laptop monitor I am greeted with 'Unable to save display settings.' when I attempt to save. This dialog is shown twice. Has anyone else experienced this or know of a workaround?

A:Unable to change primary display when using dual monitors

Same here! Any solution? Works fine, btw my monitor is the secundary and my tv is the primary. Microsoft can't make a feature to change the ID's of the monitors? so simple!

Hi, my explorer.exe crash when I change my display to dual monitors, both screens appears well, but my mouse cursor changes to the loading one (blue circle turns in row) and when I click anywhere in my desktop (both on screen one and two), explorer says a problem occured and I must close it...

Is this a well known problem ?

I installed my latest graphic card drivers for my Radeon HD5850, don't know what to do...

Thanks !

-edit- when this problem happens, I can view the details, the event problem is named "AppHangB1" and the problematic application is explorer.exe of course

Can you take a look in event viewer for errors that apply?

There are several ways to find what the problem is. The best is to go into event viewer (type eventvwr in search). Go to the windows log>application tab.

You want to look for critical errors (they have red in the left column ).

When you find them you want to look for critical errors that say app hang, app crash, or anything that relates to the problem.

When you find them please note the event ID, and the source codes and tell us what they are.

Let us know if you need help with any of this.

We're having difficulty with P2414H and P2314H monitors not entering sleep mode when plugged in via Display Port. As soon as I unplug the Display Port connection, the monitor says that it doesn't see a connection and is entering sleep mode (Windows 7 Pro, desktop or laptop). But plug the Display Port cable back in, and the monitor will go blank, but not enter sleep mode.
During sleep mode the power drops to the backlight and the power button pulses. What's happening in this case is that the power button stays lit as does the backlight.
We tried the test with a VGA cable on the 23" monitor and it properly went to sleep mode. We tried a DVI cable on a 20" Dell monitor and it also goes to sleep mode properly. The issue only seems to occur when using the Display Port.

My old monitor has problems turning on, I can leave it on for 30hrs before it decides to display a picture, or I can manipulate it by unplugging the DVI cable from the back, but sometimes even that takes a few tries. It's off warranty and for reference it's a Samsung SyncMaster 226BW.

So I bought a new monitor and I have it plugged in using HDMI, but a problem I get is that when both monitors are plugged in the HDMI has no display until it gets to Windows, so I cannot see the boot process of my PC, because my old monitor as explained above has problems turning on.

Was a hindrance today when I was tinkering with my SSD and had to go to BIOS, and frankly I'd like to be able to see in case anything goes wrong, like a BSOD or Windows update etc.

So how do I get my HDMI monitor to give me a picture when the other monitor is plugged in. My new monitor is another Samsung, SyncMaster SA350.

A:Dual Monitors, HDMI monitor doesn't display BIOS

Short of something like this,

Newegg.com - BYTECC DVI-HM DVI Male to HDMI Female Cable Adaptor

not much as that is a function of the video card and nothing to do with Windows. The only way would be to try and edit the video card's bios so that the HDMI port is made to be the primary port when powering on.

Failing that if the old monitor is that bad, why use it? If the new is the only thing connected then it should display the bios screen when booting up.

Both of my monitors are working fine, but it is just the same picture being duplicated. The point of this setup is obviously to get an extended picture rather than having two monitors showing the same thing. The problem is, when I go to display settings, only one monitor is detected (which is not even technically true since both are lit up). The computer is an HP Pavilion 550-152I, and the monitors are running off of HDMI cables (the computer has two HDMI outputs).I have checked the display settings both by right clicking on the desktop and by going through the Control Panel, but neither is detecting a second monitor.I have tried updating display adapter drivers via the device manager, but it made no difference.Any suggestions?

Win 7 x64, NVIDIA GeForce GTX 550 Ti I seem to have gotten myself into a 'pickle'. To start with, several years ago I had set up the desktop with two monitors and had it so that the desktop stretched across both monitors. That way the mouse could traverse both, back and forth. I was looking at the settings this morning and realized that the 32" LG monitor on the right now indicated a resolution of 1920x1080 which was all wrong. That was the resolution of the left 32" Samsung. But in fact the resolutions were both at the maximum for their ability. The left samsung was, in fact, displaying at 1920x1080 and the right LG was at 1360x768, it's maximum. (why the disparity between the the two? I was given the LG; what can I say?) So here is the problem: Now, not only are the monitors correct in possible resolution but are indicating incorrectly; and, I can no longer run the mouse from the left to right. It is stuck on the left. The display adapter is a NVIDIA GeForce GTX 550 Ti. I have two possible ways of manipulating this. One with the Nvidia control in the tray and the other in Control Panel > Display > Screen Resolution. First I tried selecting "Extend desktop to this display" but the mouse is still stuck on the left. So how do I correct the wrong info on each display and how to get it to allow the mouse access to the other display? Maybe the way is to somehow go back to basics then redo but I am not sure how. http://www.sevenfo... Read more

My Dell Optiplex 990 SFF has an Intel 2000 which I'm learning is no good.  I hate that my screened looks super stretched vertically and no matter how much I play with the resolution I can't fix it.  It's hurting my eyes. 
In addition I wanted to set up dual monitors with extended display.  While it's detected, identified, and showing the desktop on both monitors it's in duplicate and I can't get  the extended display to work. 
I'm no good at computers and have spent HOURS trying to understand all of this.  My guess is that I need to upgrade the graphics card?  I feel like I can do this from a youtube video.  I'm just not sure what I need.  I don't think I need anything fancy. Just something basic that will let me do the dual monitors with extended display and address the stretchy screen problem.  Recommendations?  

A:Dell Optiplex 990 SFF Graphics Card & Dual Monitors with Extended Display

Maximum power consumption for SFF is 25 Watts the best card the machine could operate with is:
VisionTek Radeon HD 6350 SFF Low Profile Graphics Card - 1 GB DDR3
From what I understand that card is not very powerful but might be enough to operate multiple monitors in low resolution

Having just upgraded from XP using the Nvidia dual monitor desktops for years, I was surprised to find Windows 7 has this feature in-built with the added bonus of slideshow desktop images C00L!
So beyond Win7 eye candy which is better, Does it come down to games running faster under the Nvidia dual desktops, what is the general preference here?

A:Is Nvidia dual monitors a poor cousin to Windows 7 dual monitors?..

afaik, there is no real performance difference, as all stuff is handled by the nvidia driver anyway.

And of course the more monitors the higher performance hit as there is more screen surface to work on (the same as increasing resolution).

Btw, the main pityfall of the multiple monitors is that the taskbar is only in the primary monitor, but there are a ton of good third party programs that can handle this, like Actual Multiple Monitors.

Secondary display : dell 2 u2717d
Built-in display : laptop xps 15 9550 in on or none

Do you guys have the same issue ? or anyone already solved it ?

(The TechCenter asked me to use mDP and DP instead of using mDP and HDMI, the issue remains the same fyi whatever the combo between mDP, DP and HDMI)

I have a Lenovo Yoga 920. When I connect a single Dell Monitor through a USB-C to HDMI adapter from j5create, the screen appears to be the same as I swap monitors in and out. However, when I used a j5create adapter to plug two of the same Dell monitors in, they're is a visual difference between the two. I'm not familar enough to know if it's color/contrast/brightness/etc, but am confused as to why two of the exact same monitors would require me to set up a custom color profile to work. Shouldn't it be as straight foward as plugging the identical monitors in and expecting the same visual result between the two?

Hi, I have a Dell Precision T3620 with only the integrated Intel HD Graphics 530. The motherboard has 2 display ports and an HDMI. I have 2 monitors, both with DVI + VGA inputs. I bought 2 adapters (display port to VGA) but I'm not able to enable both the monitors. The second screen is not correctly identified and remains black. Is it possible to enable both the display ports? I read that Intel HD Graphics 530 has the multiple monitor capability. I've looked for a bios setting too, but I don't see nothing like "enable multiple monitor". Can someone help me? Thanks

Morning, Trying to figure out something here, this is, for all intents and purposes, something new for me, as I've been mostly a "Mom n Pop" Tech vs "Business Tech" so, anyway. I'm working with M900, and M910Q with Intel 530 Integrated for video. I'm trying to trouble the following issues to verify if I missed anything, before punting said minipcs to Lenovo for RMA. Anywho, issues: 1. A M910Q, only the DP port with the metal bracket will work. When the Primary is plugged in, any secondary plugged into the other ports will show up under that port when looking at it in the Intel GFX Display view. I figured this out when I changed the resolution on the 2nd monitor, primary changes. Primary is the live monitor. 2. We have a number of M910s and M900's where when trying to use dual monitors, thru DP -> VGA or DP -> DVI. Monitors would flicker like strobe lights. This can sometimes be bandaided by swapping cables and adapters, but not completely remove the issue. I will point out that we do not have any actual DP Capable monitors on site. Not yet anyway, and those that will be, are going to ThinkCentres with Discrete Cards in them... Ideas? Am I miss anything? I don't see anything in the BIOS to help me, and updating the drivers doesn't seem to provide resolution either. Most are running old drivers, but a few are running the latest for the machine.

So i'm using a Folio 9470m at work on a 2013 Ultraslim Docking station with 2 Display Port connectors, but if i attach two screens to those it only displays them as one device and mirrors the image on both screens. Furthermore if i go into the screen and resolution settings, both identify as screen 1, but i can set 3840x1080 instead of 1920x1080 and at that moment the picture will span over both screens as one. The downside to this is that the login screen, windows i open for the first time, they're all gonne appear in the middle where the bezels are, it handles them as one bigger screen and not as 2 screens that extend each other. I need them to be detected as 2 seperate screens, and so far i have had no success. Has anyone experienced this or knows a solution? I really don't want to connect the second screen via VGA. Can the folio handle 2 display port connections on a dock? Is this maybe the cause?

As far as I know the  Folio 9470m doesnt support more then one external display.  I think you can verify this by having a look at the quickspec document for the model.

I have an ATI All-In-Wonder Radeon 9600 video card. It's been working properly for quite awhile and now suddenly the cursor moves to the second monitor when I drag the cursor beyond the bottom of the first monitor.

It used to go from one monitor to the other by dragging it from left-to-right. I can't figure out what caused it to start doing this or how to go about getting it back to the way it was before. Any ideas how to change it back. Any help will be appreciated. Thank you!
