You're the first one to ever report this error, so I can't think of a reason this would happen. Do you see a * in the monitor list? Try running as administrator.

That looks like FreeSync is disabled. Make sure FreeSync is enabled in the monitor's menu.

Well it clearly was enabled - judging from the monitor's OSD. But then I unplugged it from the power and DP cable completely. Hit some of the buttons to clear the capacitors and put the cables back in. I then disabled FreeSync and the re-enabled it. AND NOW IT F*CKING WORKS! I thank you very much since it saved me from a lot of hassle. Sent some coins via Patreon.

I know this probably wont work but I want to at least try it out (mostly for fun).

I have a Dell XPS 15 9550 (i7 6700hq, 960m) and I want to try to get 4k HDR to work as an output. The only output is HDMI 1.4? so 4k 30hz max and definitely not enough bandwidth for 10 bit.
That was where I left it a few years ago but now I got the idea of using the thunderbolt 3 usb c port instead. Thunderbolt 3 can always be used as a simple DP 1.2 out and that actually works for 4k60hz + HDR. I obviously wont have DHCP 2.2
but I knew that from the start, my CPU/Intel Graphics just don't support that.

I got a usb c to HDMI 2.0 adapter (basically gets a "native" DP signal and converts it to HDMI 2.0) and actually got 4k60hz to work just fine with my Samsung NU8009 as a test device. All good? Sadly not. I enabled HDR in the external device settings from my TV aaaand? Nothing. Windows doesn't recognize the display as
anything other than 8bit sdr. Tried different resolutions and still nothing. The adapter should be fine and support HDR. I tried different refresh rates and still nothing... maybe it just doesn't work without "actual" support in the iGPU but I honestly don't see a reason why it shouldn't work if I have the bandwidth.

Now I tried CRU to add an extension block with HDR support, maybe that is enough to fool Windows? Yeah... no. It only shows "default extension block" https://i.imgur.com/NfYwyl0.png
I tried to add one which results in my TV not accepting the signal. After a bit of trying a few things out I realized that literally EVERY modification gets blocked by my TV. Even lowering the refresh rate by 1hz gets blocked.
Just to make sure that the adapter isn't to blame I tried to connect the TV to my native HDMI port and lowered the refresh rate from 30 to 29 and I still got blocked. Also my native port also doesn't show any extension blocks https://i.imgur.com/6rfloqg.png

Any idea what to do next? Can my HDR plan work or is it just impossible, even if I get CRU to work with my TV?

I dont see an * mark in the monitor list and running as administrator doesn't seem to fix it still

I want to add a video tutorial to this post, maybe someone will be useful.

Does anyone own the Samsung CRG9, or another Super Ultrawide like it? If so, can you post me what timings you used.

I have the Samsung CRG9 and it is claimed by other people who own it that it can do 144hz at it's native resolution. When I select it, it does set it without issues, but when I run the ufo test there obvious skipped frames. So something tells me it's down to a timing issue. Any suggestions to tweak it would be helpful.

my laptop is thinkpad t440p
the spec are
4700MQ
intel 4600
and gt730M

i can not change the refresh rate what so ever i do.

i tried this steps but not work:

on windows 8.1 installed the latest driver and tried to change from control panel of intel but it show that it exceeds maximum bandwith i tried on all resoultion i tried to underclock the refresh rate to 58 or 59 not worked i tried everything it can not add any new values.
i tried CRU added new values and clicked on restart 64 and restarted my laptop but the values are not in the control panel or not in the contorl panel of windows nor in the list all modes option.
i tried to overclock the other montiors on the CRU (the not active monitors) same thing. i tried on older versions of the driver same thing. i tried new apps same thing.

and for windows 10 i tried all the steps above but the same thing.

and my gt730M has no refresh rate or custom resoltions option it has only 2 options.
what should i do? please help me guys!

---

The values are not even appearing what should i do now please guys!

Did you try the alternative method?
