Hi, So i have a 3070ti and i had a lot of screen issue with it. I plug it on my tv on 4k120hz ( on a hdmi 2.1 port), and a lot of time, the sceen go black and come back, but sometimes, for getting back the picture i have to shut down the tv, or unplug and plug it again on the tv. I tried different cables, i bought at least 2 cables, and tried the one from my serie x and the one from my ps5. After a lot of times, since i mainly use my pc, i thought, if it's not the cables, it's the tv that have issue with 120hz ( it's a tcl c825), but in the end, even changing the frequency and set it to 60hz or ( 24hz while watching movie), i have this issue....so it's not a issue about frequency in the end ( and the tv that can't support it). Lately, i played a lot with my consoles on 4h120hz....and there is no issue.... I did completely god of war ragnarok on my ps5, no issue with the 120hz on. I played a lot of elden ring and modern warfare 2 on my serie x, no issue. ( 120hz still on too). So in the end...i begin to thought, it's windows or the gpu or the driver from nvidia. And now, i m sure, it's gpu related from Nvidia. Yesterday, i plug my pc to my switch 4h120hz ( since i bought a soundbar with earc), and when i plug my pc on it, the screen don't work at all where my two console never had issue with it. I look into internet, and wanted to buy another switch, and read the comment and peoples with 3080 etc..had the same issue, sceen not working etc...So it's clearly an issue with 30XX gpu, maybe it's the connector, maybe the bandwith from this connector is not good or driver issue. Sorry if it's not that well written, i m french. Solved !!!!!! This is the solution : Download the application cru and make a change of bandwidht !!! in bottom "extension blocks" there select 1 row and click buttob edit. In dialog see "data blocks", row: "HDMI 2.1 support" select and edit In new dialog field "Maximun FLR rate" change to 40 Gbps Its all, save all and reboot pc after Thanks to someone on telegram that gave me this solution ! By the way, the serie x hdmi output is only 40gb, this is why both consoles didn't have issue on my tv. And a lot of tv make only put hdmi 2.1 with 40gb !!!! this is why a lot of people from different brand had this issue too !!!!! Nvidia should really look into it and put a option about changing the bandwidth directly on control panel !!!!
