I have my Dell U2725QE monitor connected to my Nvidia 5070 TI using a DisplayPort cable. I have then connected my Philips 279M1RV monitor to the DisplayPort output of the Dell monitor.
As seen in the manual of the Dell monitor on page 19, table 14 it does support 2 monitors at 3840*2160p, both running at 120hz.
However when doing so I get weird artifacts on my Philips monitor. It works great at 60hz and even at 98hz. Using the Philips monitor with a DisplayPort cable directly from the GPU works great as well up to 144hz.
What could the issue be?
