Q: Lenovo M910s dual display using display port not working

Good day I am using the ThinkCentre M910s and would like to use a projector from VGA and the local screen on display port. However, both display ports are not giving any signal to the monitor. I have tried another monitor and a different cable with no luck. The computer does not Auto detect the monitor as well. Plaease assist with any solutions or ideas you might have to resolve this. Much appreciated.

Here is my situation,
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.
Anyone have any solution/knowledge to this?

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'm using a Dell U3415W monitor. My video card is AMD Radeon RX480. The monitor is connected via DisplayPort to my computer. The monitor is connected via HDMI to my work laptop. When I want to switch over to HDMI, it acts as if I shut off the monitor on the Displayport shifting everything over to my secondary monitor. It causes no problem, but drives me nuts because when I switch back over to DIsplayPort, I have to move my open programs around again. Is there any simple way to make this stop? If I don't use DisplayPort, and instead use HDMI/DVI combination, the behavior described does not happen. I'm guessing that is just the way it is, but I'm hoping there is an easy way to make it stop.

I have 3 monitors connected to an AMD HD5770 graphics card. Two monitors connect via HDMI, and the third through a Sapphire Active DisplayPort->DVI adaptor. Things have been working fine for years, but recently I started sleeping my computer when I am not using it during the day, as opposed to my previous habit of leaving it on all day and then shutting down at night, and a couple of days after starting this new habit, I received a 'Display Port Link Failure' message:

"The system has detected a link failure and cannot set the requested resolution and refresh rate on your DisplayPort display. Your display might not support the requested resolution or there may be an issue with the cable connecting the display to your computer"

Now, even upon resuming my normal habit of leaving the computer on and shutting down, the monitor will work sometimes but randomly stop other times.

How can I either fix the issues with sleep, which I would prefer since I want to save energy (a money issue rather than believing my actions make any difference to the environment), or if there is a problem somewhere, determine if it is the graphics card or the adaptor that needs replacing.?

A:Display Port Link Failure, Active Display Port->DVI

It could be the hardware is starting to give out. Not all problems are software related. Going to be hard to nail down if you don't have another cable. Could be the cable or the port.

Any way to test with a straight cable, not the adapter cable?

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.

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.

I just purchased an adapter plug that allows me to connect my Lenovo/IBM thinkpad (T420) to my HDTV by plugging the HDMI cord into my TV and the other end to this adapter plug which converts the HDMI cable into a male plug which fits into my display port (there is no HDMI port on this model computer). It worked, but now I can't remove the adapter plug...it's stuck in the laptop display port. I do not know if the problem is caused by the male adapter plug or the female jack in the computer, but they're locked together now.

I have previously read review comments (on these HDMI/display port adapter plugs) mentioning this jamming happening on more than a couple occasions, but I don't recall any resolutions being mentioned except to break off (and destroy) the plug and possibly damage the display port as well. I called Lenovo tech support but they said I'd have to mail the computer to them to get it fixed. I'd prefer avoiding that if possible even though my warranty is still in effect and it would be of no cost to me.....just time lost without a computer.

I'd greatly appreciate hearing from anyone who may be aware of how to resolve this problem (and also how to avoid it happening again) without doing damage to either the plug or especially the computer display port.

Thanks for your consideration in any case....

I recently hooked up a secondary monitor to my ati 9800 XT, and its crap!

It's a Goldstar Stuidoworks 76i monitor. I have a dvi-vga adaptor and a regular vga-m/m cable. the problem isnt with the dvi cause if i plug my good monitor into the dvi adaptor, it works well and the 76i is still blurry.

the problem is if i change the resolution to anything greater than 800x600, the picture gets very fuzzy, and unusable. i've tried lots of different freq. combinations, and tried changing the colour as well. i looked all over for drivers for the monitor but i didnt find any for XP, i found something that was basically colour profiles, i loaded them, but they didnt change anything.

am i forgetting something? or is the monitor just CRAPOLA?

thank you so much for your help!!

A:Fuzzy Secondary Display? 9800XT dual display issues.

Well since you checked to DVI adapter with another monitor I say your monitor is going bad. How old is it? There might be a label with the year on it the back. I have seen this happen to monitors only old 3 years old but usually it monitors older than that.

Other signs indicating its near death is a high pitch whine at higher resolutions or max brightness and contrast.

Tell us what you find.

My ThinkPad T500 running 64-bit Windows 7 Professional Edition worked great on and off a mini docking station with 2 external monitors. The dual-display setup allowed me to have more desktop space; when needed, I can take the laptop off the docking station (following undocking steps) and use it anywhere. This convenience no longer holds after upgrading to Windows 10.

With the T500 in the docking station (LCD lid closed), I can use the dual-display setup as in Windows 7. However, after shut-down and remove the T500 off the docking station and the T500 laptop becomes unusable because its LCD display doesn't show anything after boot. (While booting the laptop's display shows the ThinkPad boot logo and then some DOS-mode boot messages and then the windows 10 logo and its dotted spinning wheel; after the initial boot the display went blank and the Windows 10 desktop doesn't come up.)

The only way to make the T500 laptop usable on its own is to go through a "preparation procedure" and here is how the procedure goes: While the T500 is on the docking station in the dual-display setup with the 2 external monitors, open the T500's lid and set its display as the main display and then select to disconnect the other 2 external displays (in the Settings -> System -> Display page); then , in the T500's LCD display, select the shut down. Once the T500 is properly powered off, remove it from the docking station and the T500 can work on its own as a laptop supposed to be. W... Read more

I have a T460 with Windows 10 Pro. It is normally docked in an Ultra Dock. I have an external 4K monitor connected to the Display Port on the Ultra Dock. A week or so ago the display suddenly changed to vertical lines in strange colors. I have determined that the problem is not the cable or the monitor. I changed the DP cable, and the problem remained. When I connect the monitor directly to the mini DP on the T460 it works correctly. This seems to exclude the monitor, the display drivers and the DP driver in the T460 When I connect the monitor to the HDMI connector on the T460 it works correctly. This seems to exclude the monitor, the display drivers and the HDMI driver in the T460. When I connect the monitor to the HDMI connector on the Ultra Dock it works correctly most of the time, but I see occasional flashed of the vertical lines. When I tried a replacement Ultra Dock with the DP connector, the problem remained, but the connection between the T460 and the Ultra Dock was not secure. I returned the second Ultra Dock. All this seems to point to something in the T460 after the DP hardware but before the connector to the Ultra Dock.  Has anyone else seen this problem?

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?
