Dell U2711 Display: Troubleshooting power ok, possible backlight but no picture

Thu, 31 Mar 2022 17:16:47 -0700

Hi, my 2711 almost toppled over today (was putting on a stand) but I caught it. Didn’t think anything of it until I noticed I was getting no picture. If I power cycle, no input cables attached, I don’t get the Dell boot up logo or any of the “no source” messages you’d expect. It’s just black, blue LEDs light and function, and I /think/ the screen is glowing a bit. Hard to tell in a well lit office. I was thinking of taking the back off and looking for a solder crack or similar, and maybe getting some replacement parts. I know it’s only worth $100 these days but it’s a fun project. Is there anyway to troubleshoot if it’s the boards before I buy some. What else could it be? Thanks!

UPDATE 2022-03-31

Pic of what I re-seated to make it work again! Thanks all!

Dell U2711 Display: Blocky image at forced 1440p resolution

Tue, 08 Dec 2020 00:57:26 -0700

Hi folks,

I was wondering whether anyone has come across this problem with the U2711:

After a move (the culprit), I cannot set the resolution to the maximum 1440p any more. Most Windows PCs will strangely default to a 16:10 1680x… resolution. If I force it to 1440p via the graphics card, then the image is all blocky.

Currently, I’m using the display as a “TV” on a Linux machine and I was able to coerce at 1080p signal out of it. There are vsync issues with it though. Very odd.

The on-screen menu is sharp though.

Obviously, this is damage is somehow from the move. Maybe temperature fluctuations and condensation caused it? Beats me. I’m hoping someone else came across it and had luck with fixing it. It’s a nice panel after all.

Thanks a bunch, fixers!

Best,

Mike

PS: I forgot: tried various cables and pretty much all ports on the screen. All the same.

Luckily enough, when I tried to connect the screen via display port again, it now shows 1440p resolution. Sweet, no need to open up the monstrosity.

The monitor has had no physical damage, was working perfectly now has many artefacts and the screen glitches. I have attached images of the issue. Is this a T Con or Main board issue?
