Friends screen is a 90's Mess

[Meag]

So my friends monitor decided to go back to the 90's and add some colour to his screen, anybody know what the issue could be? Tried installing new drivers for the graphics card but had no affect, also tried a new monitor, it didn't have the rainbow issue and tried a different hdmi device on the monitor below and it worked.

Is your friend's GPU overclocked? Also, did they use DDU to uninstall and reinstall the drivers?

Is the GPU crashed? Kinda looks like an HDMI error as well though.

They used the tool that was located on nvidia's website to uninstall the drivers. It is not overclockeded. This was a issue before reinstalling the drivers.

Go into any Nvidia overclocking software; such as Afterburner. Check if the core clock is locked at 300 mHz.

 

If so, sudo a soft restart in the command prompt.

Actually, try this. (Recommended you have integrated graphics as well.)

 

Device Manager > Display Adapters > Your GPU > Disable (DON'T DO THIS IF IT SAYS IT WILL STOP THE DEVICE FROM FUNCTIONING.)

 

You should get a flicker

 

Enable

 

If it boots to a black screen, boot to BIOS and load with a low resolution driver and restart the computer, or boot from Safe Mode (F8)

Ok so you tried another cable and that worked? Just use that cable then? 

[manikyath]

i'd suggest these:

- different cable, and ports on gpu and display if possible

- DDU and reinstall drivers

- try a different display with the system

- open cmd as admin and run "sfc /scannow"

- try running off of on-board graphics if available

- further swapping around of parts if spares are on hand.

Tried different cables, didn't change anything. Used the cable on another device and work fine, plugged pc into a different display and it worked fine, plugged a different device into monitor and it worked fine. Already reinstalled the drivers and don't have any parts in hand.

 

The only time it happens is when he is connected with that PC to that monitor. All other devices work perfectly fine without issues, the same for the HDMI cable.

I've had 2 Graphics cards die on me in the past, and they both looked like that. It's weird that it works OK with a different monitor.

Is the graphics card trying to run the monitor at the wrong refresh rate?

Nope, the refresh rate is correct, tried changing it to be sure when I was troubleshooting earlier but didn't change anything.

its not so much the reinstalling, but the DDU bit, makes sure your computer doesnt remember any settings either

If it's not the PC, it's not the Monitor, and it's not the cable, then it has to be something Software/Firmware related. Drivers, or something with EDID. Have you tried Uninstalling the Monitor in Device Manager?

Try going to the Nvidia control panel (right click the desktop to find it), go to change resolution under display, and try changing the colour depth around.

It looks like a borked GPU to me, but I've seen odd colours like that when a computer was set to the wrong colour depth only in that case it only happened in certain games.

Worth a shot though.

Nevermind, we ended up fixing the issue
