I can overclock easily to 96Hz, but as soon as I add the HDMI block in CRU it has a lot of artifacting. Underclocking the monitor below 55Hz also results in problems. Could this be an issue with my cable, or perhaps the graphics card? I have tried many combinations except for a different cable and gpu.

You can't overclock with HDMI. That monitor uses dual-link DVI, and HDMI is single-link, so it can only handle half the bandwidth. What happens below 55 Hz? That monitor should be able to handle lower refresh rates.

First of all, thank you for taking your time to answer me, Im very grateful.
Secondly, I did not try the HDMI block while the monitor was overclocked, since I did read through ALOT of forum posts before giving up and asking here However even at 60Hz I got artifacting with the HDMI block, and thinking it was some sort of bandwidth issue I tried downclocking the monitor - which it hates. My thick 28AWG cable arrived today, which seems to be able to power the monitor at 115Hz, sadly not 120, but it still completely artifacts with "tv-static bars" at 55Hz or below, even with the new cable.
Edit: FreeSync works (I tested it, must have been cable issue because screwing tight made everything suddenly work) between 30 and 50 Hz time to fine tune.
Thank you for this tool!
