My 144Hz monitor is locked at 23-24fps and can't find a solution for it

[Matrooper]

My monitor model is: XB270HU

GPU: Zotac GTX 1070

All my DP's are connected to my GPU

I'm using Windows 10

 

The steps i have taken are:

- Going to windows or nvidia settings and trying to change the Hz

- Checking for windows updates

- Going back to a previous nvidia gpu driver

- Trying my old displayport cable & one from a friend

- Disabling G-Sync

- Searching online (found nothing)

- Contacting Acer support (still need an response from them)

- Trying to make an custom resolution with custom framrate

- using a different power cable and different wall outlet

- trying my other displayports on my pc

- connecting the monitor to my friends pc (wich also has the same graphics card) still the same

- going into the settings with the buttons on my screen itself and trying stuff out

- unplugging 2nd screen

- unplugging the monitor from power for a day

- deleting my monitor's drivers

- trying the reset button on my screen

Try the reset function in the on screen display?

@Matrooper how do you know it's locked at 24 FPS?

The one I don't see you having listed, but I'm assuming you tried: a different DP cable?

because i can't change it and because my monitor says it's at 24fps and because i'm used to using 144hz and i can see the difference

I read the list twice and didn't see, haha.

 

Anyway, a few thoughts, though I'm going to assume the logic board on the monitor is probably damaged.

 

Unplug the monitor, then hold down the power button for 15s. Then plug it back in & turn it on. It's a Power Cycle and it occasionally works on "sticky" problems.

 

Is the monitor new? Because you'll probably need to RMA it.

If you've testing it on other systems and it won't go beyond 24 Hz, then it has to be hardware. If some sort of power cycling or reset systems aren't working, something must have broke at the hardware level.  It's possible cracking opening the paneling and cleaning it out might work, but you're looking at probably a toasted monitor.

 

Any electrical storms or power outages lately?

well, like a week ago my monitor gave same strange pixel screens when launching a surntain program..but only if i launched that program so idk if that was a sign or not..+ when i got the problem my room was cleaned by the cleaning lady..you think something silly like some water or stuff can cause this? Because i don't have a clue what to do

Looks like there is a standard 3 year warranty. So I'd start tracking down the paperwork/invoices for the monitor.

 

The locked at 24 Hz is weird, but it's also possible the G-Sync module died. Something could have gotten in there, or some other issue could have cropped up. Bad silicon batch that just takes a while to go. I don't know if there are capacitors within the monitor, but a cap could go bad.

No solution listed, but it's another G-Sync monitor stuck at 24 Hz.

Depends if it was an authorized seller or not.

While you tried CRU, what was actually available in the listing?

 

You might also be able to dump the EDID and examine that, though I don't think there's much saving the monitor from duty as TV.
