Monitor issue

[Ayhamb99]

I have the AOC C24G1 24.0" Curved Monitor as my primary monitor. It's 1920x1080 144 Hz with a VA Panel and i bought it around October of 2020. The monitor has been great for me so far but I started having this issue show up for me for some reason. If I haven't used the montior in a while and I turn it on, this bleeding starts to happen. This issue usually happens when i return home from traveling and I turn on the monitor after a couple of weeks of no usage i.e generally just after some time of no usage. This bleeding only happens when the refresh rate is at 144 Hz, if I drop the refresh rate down to 120Hz the bleeding stops, rarely sometimes though the bleeding happens even at 120 Hz and I have to drop it down to 100 Hz. After a couple hours of the monitor being on, if i try to revert the refresh rate back to 144 Hz, it works and there's no bleeding.

Any ideas on how to fix it or is it a sign that my monitor is going to die soon.

Step 1 - reseat the GPu, also give it a clean and visual inspection. Also check the contact points in the PCi-e slot on the MB.

Step 2 - Try a different cable.

Step 3 - Try a different monitor (if possible)

Step 4 - The GPu is cooked and im sorry for your loss.

Step 4.5 - Pull out your wallet and buy GPu

::EDIT::

That does look to me that the GPu is cooked but im crossing my fingers.

If you can test the 2060 in another computer, It will also help you see if its really the GPu that is cooked.

Assuming the cables are securely fastened and the card fully seated, you need to isolate the problem to the monitor or the computer. I would try that monitor on another computer or another monitor on that computer and see if the problem persists, and where.

If it appears the problem is in the computer and not the monitor itself, I would swap in a known good power supply to see what happens. Since EVERYTHING inside the computer depends on good, clean, stable power, you need to verify you are providing it.

I have a 2nd monitor that i use in combo with my main monitor. That one has been running fine constantly with absolutely no issues what so ever, so i think it is mainly a monitor problem more than a GPU problem because the 2060 hasn't really shown any signs of erratic behaviour like crashes or erratic temps that would indicate problems. I cleaned the fans and heatsink with an airgun last week as well and temps are all fine with no erratic stuff. I might do a stress test on it just in-case.

I'll still recheck everything regardless, unfortunately I don't have a spare displayport cable so it'll be a couple of days before a new one arrives if i were to order.

I don't have another computer near me right now that I can use except if i rebuild my system with my old 9400f and B365 motherboard, however one of my friends has an old GTX 970 that he still has after upgrading to a 6700 XT, perhaps I can ask him if I could borrow the GTX 970 or If I could test my 2060 in his PC, he's on vacation though so no idea when he'll be back lol.

I run a 2nd monitor in combo with my main one. The 2nd one works fine with my GPU, albeit my 2nd monitor is a cheap 75 Hz monitor. I'll be testing my GPU in my friend's PC when he gets back or borrow his old GTX 970 and test it in my PC.

Do both monitor connect via the same type data signal? That is, are both HDMI or both DisplayPort? Or do they use different types. I would still swap just to verify it is the monitor and not the graphics solution.

If it does conclusively point to the monitor, there probably is nothing you can do to "fix" it. The only option may be to go with a work-around by switching ports/inputs on the monitor.

Warranty or e-cycle monitor if you lack the skills and resourceful nature to determine if it can be repaired.

 

[Bill_Bright]

It is not likely the cost to repair a 4 year old monitor would be economically feasible unless the fault was visibly obvious and the replacement parts readily available at an affordable price.

But at this point, it has not conclusively been determined it is the monitor. So recycling at this point would be premature.

@Ayhamb99 - got a laptop?

I do have a laptop, regardless though the only issue with this is that it prevents me from running my main monitor at its native refresh rate of 144 Hz, if i just leave it at 120 Hz the thing doesn't bleed, so like the worst case scenario if i can't fix it is that I have to play at 120 Hz from now on which isn't really something that warrants me to have to buy a whole new monitor lol, also too poor rn to buy a new one anyways.

 

[Bill_Bright]

Yes, I understand the issue. My point is, at least from here you have not yet determined if the problem is a fault with the monitor, or if the problem is a fault with the computer/graphics solution. But hey! It is your system.

Good luck.

Alright here's an update, unfortunately my friend as it turns out sold his old GTX 970 and so I couldn't do a test swap, however I believe I have found the issue which is a bad Displayport cable. As a test I used the HDMI cable from my 2nd monitor instead of the Displayport, with the HDMI cable my main monitor stayed at 144 Hz with no bleeding. I have already ordered a couple of replacement cables for me to use rn and to have backups for later.

I'll post another update on Saturday after using the new cable to see if it was infact just a bad cable all along or if I just got lucky with the HDMI cable test lol.

Looking at the video, what happens is some sort of corruption in transmitted data with from GPU to monitor or inside the monitor itself. The corruption looks similar to what happens when the clock goes askew and the data is not perfectly synchronized anymore. It makes a lot of sense that this happens at 144Hz only as this mode requires a higher data clock than 120Hz. Slower clock, slower frequency and less chance for things to go askew.

Is your displayport cable an active type or a passive type ? Maybe the cable has degraded a bit. Alternatively, it could be the capacitors partially dried out and now the power rails are noisier than when the monitor was made. As it warms up the skew might be going away. If the capacitors are a problem then over time the problem will get worse.

Also, I would expect that your monitor does not have a single native refresh rate, but a range and when you give it 120Hz signal that is how often the panel is refreshed.
