Hello, so yesterday when i went into a game i noticed that everything is blurry , thought maybe something to do with the game, so i messed with settings, nothing worked , tried clean install gpu drivers etc, and just now when i went into a game the screen went black for like 4 seconds and when it turned on again everything got even more blurry, now its even hard to read on the desktop itself letters are so blurry. I dont know much, but im guessing its a dying gpu? My gpu is rtx2060
 
If it's hardware related it could be:
  • GPU
  • The slot the GPU is in [least likely]
  • The cable from monitor to GPU
  • Monitor itself
Do you have another cable & Monitor to test to eliminate those two? Also I assume you've also rebooted the machine.

You could also try WIN+CTRL+Shift+B

Another software related troubleshoot step could be to make sure your motherboard doesn't have any BIOS updates
 
More information needed:

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

History of heavy gaming or video editing?

Disk drive(s): make, model, capacity, how full?

What game(s)?

As above: swap in known working components changing only only thing at a time.

Determine if the blurriness follows the monitor or cable or stays with the computer

If the blurriness stays with the computer then swap in a known working GPU.

My specs is - Ryzen 5 5600g
Mobo - Gigabyte Aorus Elite B550M
PSU - Gigabyte P650B Bronze Plus
RAM - Corsair vengeance @ 3200mhz
Windows 11 Pro
Kingston 500gb ssd

i bought a used gpu. Everything else was brand new. My monitor is samsung odyssey 165hz

No heavy gaming, games i play lately Apex Lengends and League of Legends, no issues with fps what so ever i have it capped at 170, allways stays at 170, its just so blurry !

I would reccomend like mentioned above.

If you have another GPU handy, try the existing montor/cable with the swapped GPU -- if it clears up then its the GPU, if not then its either the Cable or the Monitor. Then proceed to eliminate those in your means, by using another cable or another monitor which should then help you in process of elimination.

If you've tried all of those and in the rare chance it is still occuring, it could then be the slot on the motherboard, but again very rare.
 
So i just tried my 5600g gpu with a different cable and the issue is still here, so that means its not the gpu and bot the slot in the mobo, and now i have only tried different monitor and its still the exact same.... now i really dont know what causes this?

Did you say that your normal desktop is still blurry?
It's not just something as simple as your Display Resolution is set incorrectly or your Refresh Rate is incorrect for your monitor?

Yes it is , even when i restart pc and the bios menu comes up all the letters are blurry too and it never was, i have checked and tried different things with my res, but its the same i allways use 1920x1080 at 165hz, so tried different cable, different monitor, and used my cpu grapchic driver and its still the same, wonder if it could be a faulty ram
 
If the BIOS is blurry, then you can immediately eliminate Windows.

At this point, since you've tried multiple GPUs, I'd suspect either the display or the cable. Do you have another display you can try connecting to?
 
Hmm...

Lets rule some things out:

  • The issue happens in the BIOS, so the problem is *not* related to Windows
  • The issue happens with multiple GPUs, so the problem is *not* related to a specific GPU
  • You tested with multiple displays, so the problem is *not* the display
  • You tested with multiple cables, so the problem is *not* the cable
I'm leaning toward the PSU or Motherboard, simply by process of elimination. I would expect outright failures rather then blurry output though...

As a last gasp, you could try a different PCI-E slot (even if not a 16x slot) just to rule out a problem with that specific slot. Also, if your motherboard has a motherboard display output (and your CPU supports it) you could give that a go to see if it makes any difference.

Yeah my cpu is 5600g so it has vega graphics tried that too looks the same aswell..
 
So ive been trying to figure it out last 3 days , no luck wonder what i could do as i have no parts to test everything.. did RAM test no erros, tried other monitor, other cable, tried vega gpu. So it leaves to psu mobo or cpu , what most like to cause that tho

So we can eliminate the PCI-E slot as well.

I've never seen anything like this; I'm leaning towards the PSU, but I wouldn't see how the PSU could just result in blurry video output, especially from the onboard GPU. Same deal with the motherboard; I don't see how that could be the cause of this.

To clarify: You've used a second display AND cable to test? And removed all drivers using DDU and reinstalling fresh?

So i tried now hdmi cable again and with hdmi cable i get blue screen of death consistently, so im guessing my gpu is failing ? Right? Yes i used second monitor and new cable. I dont know but im guessing my gpu is failing and got damaged somehow ..

My concern would be you tested with the integrated GPU previously, which would point more towards the motherboard.

This is getting a bit outside my wheelhouse; the obvious step if possible would be to test with a different dedicated GPU and a clean driver install, which would 100% eliminate the GPU.

Yes thats what i think would be the best but i cannot get a gpu anywhere unless i order a new one, but if gpu is not the case then i dont really want to buy a new gpu, i will try and get from somewhere , and let you know.
 
I had a similar issue the other day after a windows update, screen went blurry, looked like everything
had a thin white outline, even the bios screen - ended up being a VRR issue as it persisted after a system restore and only went away after toggling the setting in windows and on my TV, at least I hope thats what it was, turned off windows update for a week to be safe

I tried and look for this setting, but there is no such a setting like that for me to choose
 
Electrical/electrical interference perhaps...?

Are all cables and wires neatly organized or just in a big tangle?

Any recent changes: new applicance, wiring work, inside or outside? Any changes of any sort with respect to your home environment?

= = = =

Sketch out a diagram of your system and all connected devices. Include all cables: power, video, audio, network, coax, etc..

Look for any sort of loop: Device A connected to Device B connected to Device C connected to Device D, etc. ,and connected to Device A again.

Try powering your system from:

1) another electrical outlet on the same circuit and then,

2) from another electrical outlet on a different circuit.

All cables are tidy, no recent changes at my home. I will try that tomorrow , but how come could that happen or be an issue like that?
