Even with DSC OFF in the OSD, I can't enable DSR in nvidia panel. It works with my pg27aqn, but not with my pg49wcd, please fix it.

hello Kolysion, I bought the PG49WCD right because of DLDSR, since it doesn't work on the G9 OLED. Can you check if works with HDMI 2.1 and 120hz? HDMI 2.1 doesn't use DSC, while DP 1.4 is forced with DSC at 144hz even if you turn it off on the monitor OSD. Let me know thanks, still waiting for delivery.

sorry I dont use hdmi, only display port

Hey, I am soorep, couldn't access at my account anymore.

I got the monitor and managed to get it run at 7860x2160 with no issues. 

Made a simple guide on reddit here: https://www.reddit.com/r/widescreengamingforum/comments/1b04kq6/pg49wcd_329_enabling_dldsr_7860x2140...

Will post below as well:

So I own a Samsung G9 QD-OLED 240hz and a Samsung NEO G9 57'' Mini-led 240hz monitor and I am replacing both for the PG49WCD for a simple reason: thanks to ASUS capping the monitor at 144hz, the display doesn't force DSC and with a small trick in CRU the monitor can easily run at 7680x2160.
You can now enjoy the highest widescreen resolution a RTX 4090 can handle, GSYNC, HDR and QD-OLED 2nd gen panel at the same time.

This method has been tested with an HDMI 2.1 cable on PORT#1. I want to specify it since the Samsung G9 QD-OLED 240hz works at that refresh rate with lower resolutions only by plugging the HDMI 2.1 on PORT#2. PORT#1 is console-exclusive, basically.

Made a simple guide below, it requires CRU obviously:

is it safe to delete the native resolution ? if I need it back it's deleted, and I only use display port for gsync.
