Dual External Monitors on Laptop?

Q: Dual External Monitors on Laptop?

So i have a HP HDX16t with a 512MB Geforce 9600M GT video card running Win7 64bit Home Premium. The laptop has a VGA and an HDMI output. I currently have an external monitor (19" ViewSonic VX900) hooked up to the VGA output. Does anyone know if i can hook my second external monitor (also ViewSonic VX900) up as well through the HDMI port? The VX900 has VGA and DVI-D inputs, so i would definitely need an HDMI to DVI adapter (which i don't have currently). I have searched around on this, but havn't been able to find anything conclusive. Nvidia's 9600m GT page is sorely lacking in details.

I know i could set this up by buying a Matrox DualHead2Go adapter as well, but i was hoping to avoid spending an extra $200 that i would rather put into upgrading my aging monitors. Also the apparent downside to the DualHead2Go adapter is that i would need to place both monitors on one side of my laptop vs one on either side (as i had hoped to do).

Hi, New EliteBook 840 G1 with discrete graphics and 2013 UltraSlim Dock using windows 8.1. I have actually 2 issues with this 1) I want to use the laptop monitor also as a 3rd screen but i want to change primary (main) display to one of the external monitors but the laptop keeps reverting the primary (main) display back to the laptop. 2) My 2 external screens has since 2 days ago started flickering then going blank and came back again without any flickerin. Extremely anoying. Seems that the graphic card somewhat resets on screen or the other from time to time. Been trying to look at logs without any luck. Any ideas?

A:External Dual Monitors and Laptop screen issue EliteBook 840...

Sorry, I can't help fix your issue, but I wanted to let you know that you are not alone!  We have 7 Elitebook 840 G3's wth Windows 10 on the 2013 UltraSlim Dock as well, and they are all doing the same thing.  Both external displays will go black for a few seconds periodically throughout the day.   We are using HP EliteDisplay E242 displays for all except one user, who has ASUS displays, and they all have the same issue, so the display itself does not appear to be the issue. The VGA port seems to work fine, so this points to the Display Ports/driver being the issue.  I have tried all available driver updates, but nothing has resolved the issue. We are looking for a solution to this issue as well.

The screen flickers for 10-30 sec to 5-10 mins. I saw a post which is the same issue for the 840 G3 laptops that was marked fixed by HP while it is clearly still a huge problem. Please fix this issue since we bought a huge number of these laptops and we are ready to return them if this issue is not fixed.

I have a Dell laptop on a docking station running Windows 7. Everyday I place it on the docking station and use my 20 inch monitor.

My work purchased a Yoga 900-13ISK and two external monitors with HDMI and the traditional VGA inputs. I would like to connect the machine so I can run two external monitors simultaneously when I'm working from home.

I have a ThinkPad S1 yoga bought in Dec 2013. I have being using the mini hdmi to work of 1 external 1080p monitor these last few years and it has worked fine. I now want to add a new second 1440 x 2560 along side my 1080 x 1920 monitor for a dual monitor set up. (Mostly for spreadsheets, emails, web browsing etc.) I do not mind if one of these duplicates my laptop screen. I was going to get the onelink dock to enable me to do this however I am not sure if it will work. I know the resolution with dual monitors running off the dock is limited at 1200p. What I now want to do is use the mini hdmi on my laptop for one monitor and the onelink dock for the other, however I want to be sure it will work before I go and buy the monitor and dock. Alternatively I could buy an USB 3.0 to hdmi adapted to run the 1080 monitor and a usb hub for the extra usb's I will need. (I think the dock will use less processing power and would be a slicker set up so I imagine it would be better?) You?re  help would be appreciated as I have read there can be issues trying to get higher resolution monitors to work.

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, 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:Dell Latitude E7450 compatibility with E-Port Plus II with external Dual DisplayPort monitors

Did you resolve this issue and, if so, how? I have the same laptop (but running Windows 10) and the same docking station with the same results.

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.

I was wondering if there is any type of adapter that I can get to plug into my laptop so that I can use dual screens. I have a HP Pavilion laptop running Windows XP. When I go into the screen settings it has the option of using dual monitors (it actual says multiple monitors) but there is only one monitor plug on the outside of the laptop. So does this mean i need an adapter or does this mean that I can plug in a monitor and use the plugged in one and the laptop one.

It might not be exactly what you are looking for but I'm delighted with SplitView It gives you two half size screens so you can have two progs open and running side by side. I can - for no real reason! have IE open on one and Firefox open on the other. Or a Word doc one side and a movie on the other.
I find it really useful when doing cut & paste. You can easily switch between two screens or one.
Hopefully this is a link:

I have no connection with the product other than being a very satisfied user.

I have an old Compaq 1200 laptop. It had Windows ME when I got it. I noticed when I first turned it on, the display properties showed that there were 2 monitors when really there's only one (the LCD screen). And the desktop is larger than my laptop screen, so I have to place the mouse on the edges of the screen to get to the rest of the desktop. I figured once I wiped it and installed XP it would go away, but it isn't. I don't see anything in the BIOS either, the BIOS is pretty limited. Has anyone seen this before?

A:Laptop shows dual monitors, but I only have one. ???

Most laptops have a dual monitor graphics adapter, the two screen setup is very normal. It is for using an external monitor.

If your screen is displaying in "pan" mode where the display overlaps the actual screen, you have set the resolution too high.

You should always use only the "native resolution" on an LCD screen.

Well I currently have a Stuido 17 running vista. I am trying to set it up so I can stow the computer away under my desk and run remote keyboard, mouse and dual monitors. I changed my settings for what closing the lid does and am also considering buying my monitors and a Lenovo notebook port replicator but wanted to make sure this could be done before I do so. My major questions are: Can I run both monitors off the one laptop? Will the processing speed be able to handle two remote monitors run while the lid is closed? Will this support gaming quality performance? Any help is greatly appreciated. Thanks!

Based on my previous readings, it was possible with the help of an extra hardware. The Matrox DualHead2Go splitter can take one video input and split it to two monitors. you could look for similar devices or try to buy one. Its not another VGA card but it works like a router, connect your laptop to the DualHead2Go then connect the two monitors.

I currently have a laptop running with an external monitor attached and extended desktop. It works wonders. I've been itching to add my tv to the collection as a monitor for when I use the laptop for gaming. Considering, I already have a wireless keyboard/mouse, all I would need to do is add the tv as a monitor and I'll be set.
I've been looking at some usb to vga cables/adapters but not sure how they work. I really only need this monitor to be used half the time, so extending to it full time is kind of worthless.
Can you have a mix of extended desktop displays and duplicated displays across various monitors? Or, is it even worth it?

A:Laptop and external monitors

I am not sure that your laptop would have the processing power to run 3 screens (including it's own). You could manually swap the output between your second screen and your tv when you needed it without much trouble.

I would not recommend a USB to VGA adapter for gaming purposes.

Hi there guys, my name is James. I'm new to 7 Forums so please help me out!
In my work office I have dual monitors connected to a single desktop computer via DVI. I usually work both at work and home so I use my laptop alot. When I'm at home I need more desktop space so I bought 2 cheap monitors that only support VGA inputs. But because I'm using a laptop I only have 1 VGA panel. I have bought a USB 3.0 to VGA adapter and I have installed all necessary drivers to run it. So here is my issue with my display.

In the Resolution Settings it shows 3 displays. 1 Saying Mobile PC Display, 2 saying HP vs17 (My Monitor) and 3 saying Generic Non-PnP Monitor. There is nothing wrong with the monitor as it worked fine on my old windows 7 laptop. There are 2 issues here:
1.) The second monitor is called Generic Non-PnP Monitor and it's default resolution is 800x600 even though it's native resolution is 1024x1024.

2.) The screen is not being displayed even though my computer thinks it is being displayed.

If anyone can help me with my issues it will be much appreciated. I will list some basic specs and If you need any more description details feel free to ask.

My laptop is a HP Pavilion ZD 7020 with a Nvidia Geforce FX Go 5600 video card. I bought a second monitor that I wish to use for my photo editing and just because these old eyes don't like squnting at the laptops screen.

All I have gotten to work so far is that the photo I use as my laptops desktop is on the new monitor but nothing else. I am able to drag icons over to it but when I click on them the window opens on the laptop. I thought I would be able to use the new monitor as a replacement for the laptops but was I mistaken ? I did update the Nvidia driver also.


Edit: If I boot it in safe mode the new monitor seems to mirror the laptops if that helps.

Got my Dell Precision 5510 and this dock(below) . The dock is connected via a USB(from dock) to a thunderbolt on the laptop side. I have three external monitors hooked up( 1 HDMI, 1 DP and 1 mini DP). I would love to be able to open the laptop and have it work while the other 3 stay on but the laptop turns on and only two of the monitors stay on when I open the lid. Seems I can only run (3). I've tried all different configuration with no luck. Though maybe if I disconnect the HDMI from the dock and plug in directly to the laptop that would work but no. Any ideas?

Not sure if I'm posting this in the right place

I have a HP 4730s probook (pretty highly spec'd)
along with 2 x external monitors, one is connected via the single HDMI port which works in EXTEND DISPLAY mode

The other I have tried to connect via the VGA connection but I can't get both to come up at the same time

I believe it is a Win 7 issue

What I would like to do is have the HP laptop with its screen closed (in sleep mode, maybe that is part of my problem ??) with the VGA connected external monitor on my LHS in DUPLICATE mode so it mirrors the laptop display even when the laptop screen is closed and the second HDMI monitor on my RHS in EXTEND DISPLAY mode so I can drag and drop various displays (which is pretty nifty anyway)

I believe I need a VGA to USB adaptor to connect the LHS VGA monitor to a USB port
but do I need a USB 3.0 port or will 2.0 be OK of which I have 4

Or should I upgrade to Win 8.1 ???

Any advice on the above scenario much appreciated

A:Multiple external monitors via an HP laptop

What's an LHS and RHS? I've not run across any specific name that goes with those letters. Or in other words, give the full name before using an acronym for that name.

What I would like to do is have the HP laptop with its screen closed (in sleep mode, maybe that is part of my problem ??)

When the lid is closed and/or Sleep is active there is not any computing action going on so Yes, that is a problem. Some Notebooks have a BIOS setting to disable the lid close part or maybe there's a setting in Win7. The Sleep can be turned off as well as Hibernation. You may also have to adjust Power Options to make it more like a Desktop, nothing shuts down. If there's a setting choice of Never, use it. And you'll have to keep the AC power adapter plugged in. Also expect more heat when running continuously.

I'm new here, so I hope I put this thread in the correct location. I've been having an issue with my computer when I try to connect 2 external monitors to it; one via HDMI, and one via VGA. The ports are right next to each other on my laptop, so I ended up cutting the blue plastic protection layer so I could fit in it. Anyway, I can connect both monitors fine, but I can't seem to get the laptop monitor to stay on and working when I extend the displays. In other words, I have the laptop monitor and 2 external monitors which I'm trying to connect, and the laptop monitor doesn't connect when I connect the other two. When I push the windows key+p, I click on the extend option, but the laptop monitor doesn't extend, it only extends on the two externals. Now, I'm wondering if my graphics card only supports two monitors being on at a time, or if it's some random Windows 8 problem. I haven't thoroughly gone through some of

Here are some specs of my computer and monitors so you can get the picture.

CPU: Intel Core i5-3210, 2.50 GHz
OS: Windows 8, 64-bit
Graphics card: Intel HD Graphics 4000

ViewSonic VX2253 Series, 32 inch monitor
Westinghouse L2220HW, 32 inch monitor

I appreciate any help given in advance.

You answered your own question. Common Mobile graphic cards only support 2 displays any given time, be it internal+external or external+external.

Common low to mid-high NV or AMD cards do the same.

Only the new Haswell will support 3 monitors in the case of Intel.

EDIT: You could also try a USB to VGA adapter for the 3rd monitor.

Hi I'm having some troubles connecting 2 external monitors to my v570 laptop. When I connect the first one through a hdmi to dvi cable it works good to exten the screen between both the laptop screen and the external. When I try to connect the second monitor through vga to vga it automatically disables the first monitor and enables the second monitor. It won't give me an option to enable both monitors plus the laptop screen. Can anyone give me some insight on what might be causing this issue.

I am trying to add 2 external HDMI monitors to my Asus N550JV laptop computer. I connected one monitor to the HDMI port. It works fine. The other monitor is connected to the Mini Display Port using a small by mini port cable with an HDMI connector on the other end to connect to the 2nd monitor. Monitor 2 works in the HDMI port by does not work with the mini port. When I connect both monitors at the same time, both go black. Is there a manual set up to make these work. I am a stock trader and want to have 3 separate monitors, including my laptop monitor, with each showing a different page to work from. Is it possible with my existing equipment?

Hello, I have an HP 840 G1 i5 intel. I have this on a ultra slim docking station and have 2 external monitors connected via hdmi and 1 external monitor is connected with a Siig 2.0 vga to usb adapter. I can get 3 screens to work at the same time but I cannot get the 4th monitor to connect. When I go into the properties and extend the desktop one of the screens disconnects. I have searched the fourms but no resolve to this issue. I am a highly expierenced tech so please assume all the basics were done and I am just not mentioning them. All Drivers are current and up to date. Same with bios and laptop drivers. I have the driver for the monitor as well.  Any help would be much appreiated.

I am doing some research on the new W540 laptop and noticed that it doesn't have any other video output other than a 14pin monitor out and a thundrebolt port.  We would like to be able to use dual 30" 2560x1600 monitors.  Any info would be great.  I don't even know if the older laptop docks with this laptop.  The dock has multiple monitor outpots so I thing they would work but I need to know before making a purchase decision.

A:Will the new W540 laptop support output to dual monitors?

Probably not the right forum, but going to the W540 page on the Lenovo site and then clicking accessories brought up a blurb about the ThinkPad Pro dock, which included the following:
DisplayPort connector, DVI-D connector, VGA monitor port, and a Kensington security lock slot.
*ThinkPad Pro Dock works with the 2013 classic ThinkPad models, including L Series, W Series, X240, T440p, T540p, and T440 without NVIDIAŽ Optimus? technology.

I have a laptop that plugs into a docking station that runs dual monitors.

I brought the laptop on a road trip and I'm trying to open a program and everytime I open it, it goes into where it would be on the other monitor.

I can't get it on the laptop screen. Any help or ideas would be much appreciated.

I believe you can re-designate the primary monitor.
