RE: Custom Resolution Utility (CRU)
Hi everyone, I have two screens connected to my 4090 latest driver yesterday.
One is LG C9 on 4k@120Hz over HDMI 2.1 and the other one is LS49 (Odyssey Neo G9 Miniled) 5120x1440@240Hz (DSC). Basically I switch between these two regularly, at most 1 screen is enabled the other is basically off. I used multiple monitor switch tools (DisplayFusion, MonitorSwitcher etc.) also switching manually. Going to LG C9 is always fine. When switching to G9 60Hz always works. But when I directly switch to 240Hz it basically freezes all the time, completely until I reboot. (SSH to desktop works btw). As a solution I tried switching to 60Hz first waiting couple of seconds then running Enable-PnpDevice & Disable-PnpDevice then switching to 240Hz. So this kinda works maybe %60 or so. But still its nowhere near what I would call ok. I digged through some pages and some posts on Google but I couldn't find any solution. I saw couple mentions that its related with some Nvidia DSC bug. Is there any proper solution that can be achieved with CRU or some other way? |
