I have little bit progressed .
I have purcahsed more advanced usb-c to hdmi 2.1 adapter Sabrent
Now I can enable HDR on mine Sam TV and windows 11 showing in resolution I can now select 100Hz or 120Hz for 4k but when I select it it just reverts back to 60Hz .
I don't really know whow to use yours soft I have tried to do detailed resolution top one But I tried 4k@120 bit won't let me from all drop down options all red.. Only when I tried 4k@75Hz it allowed select exact reduced. BUt I have restarted windows but it is not showing 4k@75Hz option in windows refresh rate settings.
How can I add ? Or I was wondering how to do 4k@120 but with limited colour sdepth 8bit and dinamic range to limited and output color format to 444 or 422
But you don't include these options in your soft?
You need to use a DisplayID extension block to add resolutions greater than 655.35 MHz pixel clock as explained in the first post. 4K @ 75 Hz should have worked though so the driver is ignoring it for some reason. 4K @ 100/120 Hz should already be defined in the extension block in the TV resolutions data block.
DisplayPort/USB-C has less bandwidth than HDMI 2.1, so the default 4K @ 100/120 Hz requires either YCbCr 4:2:2 or display stream compression (DSC). "Native (PC)" would bring the pixel clock down low enough for YCbCr/RGB 4:4:4 without DSC, but the TV might not support that timing.
8 bpc should always be available. Dynamic range is set in the GPU's control panel and not in the EDID. RGB color format should always be available. YCbCr color formats are listed in the HDMI data blocks in the extension block, but since you're using a DisplayPort/USB-C adapter, it might be in the display properties ("Edit..." button at the top of the main window). YCbCr 4:2:2 is normally supported and should be available without any changes, but I don't know if the adapter is messing that up.
Hi Toasty thanks for the reply.
I find your software complicated.. nvidia c panel has it best and stupid intel has blocked all custmizations including colour formats and dynamic ranges
Where I should add it ? DisplayID extension block to add resolutions greater than 655.35 MHz pixel clock as explained in the first post which section ?
Edit : Found it Should I use Display ID 1.3 or 2.0 ?
- Extention block showing Type CTA-861 one resolution added which is 2k@120
- TV resolutions showing both 4k@120 and 4k@100Hz
- HDMi support max 300Mhz Only 4k 24hzand 4k@30Hz HDMi 2.1 showing bunch of many features hav eno idea what they mean ..
4:2:0 resolutions showing both 4k@120 and 4k@100
free sync range from 48-120Hz
Should I add extention block or better add new ? and choose Display ID ? 1.3 or 2.0 ?
I have added 4k@75 in top detailed resolution then used arrow up to be first then clicked on restart64 and it didn't add in windows resolution setting nor intel command center. My tv supports full 4k@120 it has hdmi 2.1 .
DisplayPort/USB-C adapter is less than HDMi2.1?? Really ?? I thought using thunderbolt 4 port on todays laptops is best connector surpassing HDMi 2.1 and USB4. Intel claiming that all connections are implemented in to tb4 .
Ma I missing something ?
According Intel it supports 8k@60 which means 4k@120 should work as 8k@60 is more bandwidth (please see the pics)
Mine TV support it I have Desktop PC and all working perfect even via HDMi 2.0 nvidia c panel set custom resol. automatically but some strange reason not from the laptop which is better equipped.. supposedly
I have Samsung Q85T 55'' 4k@120. And I just achieved 4k@120 straight away with HDMi to HDMi cable. It shows reduced colours settings on Desktop PC.
1.Outpur colour format : YCbCr420
2.Desktop colour depth 32 Bit
3.Output color format 8Bpc
G-sync - vrr working and HDR too
to achieve even RGB colour format, 10 bit output color format and dynamic range full and keep 4k@120
So I have purchased Displayport to HDMi 8K cable (see pic) connecte do nvidia GTX 1660 Super and all works. but colour formats are on full but
unfortunately g-sync and vrr is not present HDR works
It runs all colour formats RGB, full, and 10 bit (please see picture
But there is not possible to set color formats ,dynamic ranges et in crappy Intel command center.. They stated that dongles and adapters are not supported.. and here the problem lies . they even blcking custom resolutions settings.
That's why with nvidia c panel it works.. You can configure there with ease..
If we could hack old intel graphic control centre ? I can't run it ..
I think no matter what I configure in your soft , it will be ignored by intel ! gpu and its softare in windosws
We need to contact microosoft to add custom resolutions implementing into windows 11 display settings
