HDR requires hardware support. The question doesn't make sense because where is the monitor going to get the extra dynamic range from if it doesn't have it in the first place?

Also I did patch using atikmdag-patcher

It will work that way with the patch, but I don't see why you need to do that. Your GPU and the TV should both support 3840x2160 @ 30 Hz without any special tricks. The new firmware might not be handling the DVI signal correctly. Either add an extension block with HDMI support, or run reset-all.exe and reboot to use the monitor's defaults.

I think I tried to reset everything when I was troubleshooting last week, and could only achieve 1080p as max resolution. I vaguely remember when I first got the TV it only give me max 1080P so that’s when I found CRU. Super weird. I’ll try block extension HDMI. Any specific parameters? Also, how did you figure out that I’m set up for DVI instead of HDMI? Thanks again!

> No Displays found in registry

Hi I remember I tried to use this utility long time ago but fail to make it work and while experimenting I remember that I probably deleted all listed monitor. Since then I change my craphic carg from a GeForce 210 to a Geforce 710. I tried the patcher again and worked but the app still does not run. Is there a way to restore the default active monitor so I can try to add a custom resolution?.

What monitor do you have and how is it connected? You shouldn't be getting that message unless there's a problem with the monitor. The graphics driver automatically detects monitors after rebooting or running restart.exe. What does Device Manager show for the monitor?

HDMI is treated as DVI if there's no extension block with an HDMI data block. Just add an HDMI data block with the defaults. You shouldn't need the patch with HDMI either.

Great utility, got my games running at 1080p 120hz on a Sony X900E display over HDMI.

Only thing I can't quite figure out though is I want to have 3840x2160 @60hz on the desktop and 1920x1080 @ 120hz in games. I have been able to get 120hz working by creating the resolution and setting my desktop to it. When I load a game it maintains 1080p120. However if I set my desktop to 4k60 and load a game, selecting 1080p defaults to 60hz and most games don't show both res/hz as options.

I tried modifying the existing detailed resolution to be 1080p120 instead of creating an additional entry. What else can I try? I'm tempted to clear the entire list from my extension block "TV resolutions" tab and leave only the 4k60 and 1080p120 entries.

FWIW I also have an additional "display" which is my Onkyo receiver and I run a cloned desktop to it. The receiver is only enabled so I can use the second Displayport to run 5.1PCM audio. I tested everything above without having this hooked up to rule it out.

Is it possible to use CRU for downsampling on AMD Radeon 7600M? If not, what is the best way to run downsampling on AMD cards?

CRU is not a downsampling tool. The easiest way is to enable AMD's Virtual Super Resolution feature in Radeon Settings.
