There are ways to read the extension blocks, but NVIDIA's driver ignores EDID overrides for displays that have this problem, so they need to fix this first.

Samsung Odyssey g70b/hdmi 2.1 connection. If adaptive sync on - sometimes on switching full screen to borderless have black screen. Audio - working. Just full lost of video signal.
Cure - disable adaptive sync in monitor setting, thats restart monitor and image start showing up.
As i understand after google - need to corect v rate.
But in my scenary - v rate blank.

Extension blocks - empty.
If i understand correctly - i need to add "cta-861" block and use "freesync range" option with what numbers? Something like "60-144?"
Or i need "hdmi 2.x support" and "Variable refresh rate" range option ?

Are the extension blocks empty or do they say default extension block? If default, is this with an NVIDIA GPU? NVIDIA's driver ignores EDID overrides for displays that have the extension block problem, so you won't be able to make any changes until they fix this. Frankly you shouldn't need to use CRU to fix a problem with a new monitor. This sounds like a firmware bug with VRR that Samsung needs to fix, so you should report this issue to their support, or return it and get a different monitor without this problem.

Understand - thank you. 3080ti. Yes - default extension block.
Definitely it's firmware - odyssey not good with quality control so i knew something gonna happen. Got one before.
But leave it for now - if use borderless as main settings, no problem at all.
Anyway i buy it for year~ - waiting for new oled on start of next year.

I have an HDMI headless dongle that I'm trying to set to 4k 120hz. I have a 4090, so it has an HDMI 2.1 port on it. Is there any way to do this without TV resolutions?

What are you trying to use CRU for? What GPU do you have and how is the monitor connected?

Im trying to use cru for display scaling for games. I'm using a 4080 and the monitor is connected through a display port.

You say you can't use 360 Hz. What are you doing and what happens? For black bars, display scaling is controlled by the monitor, so check your monitor's settings to control the scaling.

4K @ 120 Hz would require either FRL or 4:2:0 without FRL. The dongle probably doesn't support FRL, so you'd have to add a 4:2:0 TV resolution, and you'd need both the HDMI and HDMI 2.x data blocks.

Hi, posted this to a monitor subreddit and realised I should be here instead of there. I was looking for help with adding a resolution (1920x1440) at 240hz. Please read post attatched below as I am not bothered to write out all of my post again:

Cru mirror in middle of screen

I just recently got a new 240hz monitor its the Sceptre Curved 24.5-inch Gaming Monitor and i tried to use cru to use streach res for fortnite. But after i switched to my normal resolution 1720x1080 i noticed a line in my screen almost like a mirror and everytime something passes through that line it doubles an example would be in game i see almost 2 of my chroshairs and i wanted to know if there is a fix?
