Dell U2711 Display: Dell U2711 display showing yellowish tinge

Sun, 21 Jun 2026 08:11:15 -0700

I picked up a Dell U2711 display in good physical condition, manufacturer in 2012, to use with a Mac Mini M4 running Tahoe (or other older Minis). The display boots up with a yellowish/amber tinge and no amount of brightning and adjusting contrast will get me to pure white say on an open text document. In Settings I can pick the U2711 but I'm not finding a way to calibrate it further. The monitor is connected via HDMI and set to YPbPr on the monitor controls. If I change that to RGB everything turns very pink. Same result in Settings on the Mac for Display. If I chose Generic RGB instead of U2711 the display turns pink. None of the other choices in those setting substantially reduce or improve the yellow tinge. So, as this is an older display it appears that something is fried inside like some kind of graphics board but I'm out of my depth here. Since I'm using it with a Mac I don't think that any driver updates are available for me. I'm not invested in this display because I got it for free :-) but it would be a handy upgrade for some of the other Mac Minis I have running. I like to tinker so any ideas about getting it restored will be appreciated. Once upon a time it was a halfway decent monitor. Thanks.

Dell 1908FPb monitor: Dell monitor shows a green line during boot screen even after replacin

Fri, 19 Jun 2026 22:27:01 -0700

Hello. I have a Dell monitor, and I noticed a green line/green tint appearing on the screen during the boot process, even before Windows starts.

I already replaced the VGA cable with a new one, but the issue is still there.

Since the green line appears during the BIOS or boot screen, I think it may not be a software problem.

How can I determine whether the issue is caused by the monitor itself, the VGA port, or the graphics output of my computer?

Unfortunately, I don't have another monitor or computer available for testing.

Any troubleshooting advice would be appreciated. Thank you.

While gaming my monitor display went black and wouldn't come back on. Tried on multiple other devices using another cable as well but still no image. Not even the menu will show up when clicking the buttons on the monitor.

Display: Won't turn on? LG - 34UM95-P UltraWide

Fri, 22 May 2026 21:20:15 -0700

Hi,

I was wondering if someone could give me some advice? I've never fixed anything electrical and would like to give it a shot.

My LG - 34UM95-P UltraWide monitor stopped working earlier this week. It won't power on, the white LED light near the joystick at the bottom of the screen is no longer turning on - neither is the monitor itself.

I've changed the fuse in the plug, but no joy.

I've had a look online and it's taken me down a bit of rabbit hole, I found one post that suggests the issue might be related to a EEPROM chip, perhaps it needs replacing or rebooting?

Wondering what tools would be useful to get to try and fix this monitor?

The monitor is in great condition for its age - purchased in 2014 - it's not been knocked about, I think something has just burned out (I have no idea).

It might be unrelated, but worth mentioning. I mainly used it with a MacBook Pro connected via Thunderbolt port. Never had any issues with this. In the last year or so a second PC laptop has occasionally been used with the monitor. Connecting via HDMI.

Sometimes the HDMI connection seemed a bit shaky, the monitor would make a white noise/static sound almost as if it was cutting out but only for a split second. Trying other HDMI ports on the monitor didn't seem to make a difference. Unplugging the HDMI lead and giving it a blow seemed to temporarily fix it. It was very random.

The monitor finally stopped working after the PC laptop performed a windows update.

The PC laptop wouldn't connect to the monitor and the image on the laptop was jumping all over the place. The monitor was blank, no power. Not sure if this is related?

Hope someone can offer some advice.

UPDATE #1

I've managed to open the back of the monitor. Images attached.

UPDATE #2 - Saturday, May 28, 2022

Test power adapter
I've tested the power adapter, multimeter showed 19v. So at least I know that's working as expected.

Test connector
I was unable to get the red probe deep enough into the connector, so I put it on the metal coming out of the connector, see red circle below. The black probe on a screw on the board, see black circle in the image below.

The multimeter was set to resistance mode, and it beeped.

I also tried the multimeter on two other resistance settings. First on a setting of 200, the reading was 01.0 then I changed the setting to 2k, the reading was .001

Test connector with power cable

Set multimeter back to DC voltage mode, setting 20. Plugged power cable in and turned the power on. Black probe on the same screw as before, and red probe on L713 , gave me a solid reading of 19.20
