MSI Gtx 1080ti for 1440p x 240hz insufficient?

[Sash2126]

Hello, I recently bought a used PG27AQDM.

 

Once I set it to 240hz 1440p, the screen tears/"wiggle" from time to time on the desktop, and especially in games (starcraft 2). I tried setting it to 1080p/240hz and 1440p/120hz and I've had zero trouble, but in 1440p/240hz it "tears" and sometime the screen goes black for a couple seconds. 

 

 

 

I have an msi gtx 1080ti, 32go of ram, a i5 7500 and I use a 1.4 Display port cable.

 

It is still under the 2 year warranty. Should I send it back or is it the GPU that is bottlenecking me ? I'm almost done with my next build using a rx 6850xt and a 13700k i7, so should it keep that monitor for the new build ?

 

 

 

I thank you all very much in advance,

The 1080 Ti has DisplayPort 1.4a connections, which have a maximum total bandwidth of 32.4 Gbps. It's able to handle 240hz at 1440p. Your monitor has a DisplayPort 1.4 connection, which is also capable of handling that. There should be no issues. My suggestion is for you to try different drivers and a new DisplayPort cable. If that doesn't solve the problem, the monitor may be faulty.
