Custom Resolution Utility (CRU)

[ikonomov]

As a continuation to my previous post, out of curiosity I decided to dig a bit more looking for further discussion on potential issues with such low timings. Testing for these showed no such problems on the XG27UCS monitor.

No issues with frame skipping (likely only a problem with older monitors): https://forums.blurbusters.com/viewtopic...205#p91601

No noticeable change to inverse ghosting, perhaps helped by the well tuned variable overdrive settings of this monitor: https://forums.blurbusters.com/viewtopic...664#p86652

Using lower vertical blanking should have practically imperceivable effect on input lag at 158Hz. I tried to detect some difference compared to using CVT-RB2 timings or increased vertical totals which I can get at 1080p/160Hz, but if there is a difference I can't tell without a measuring tool: https://forums.blurbusters.com/viewtopic...501#p97907

Some futher tests here.

windows 11 24h2 seems to have changed something; i cant get my refresh rate to only remain 180hz

Good night, am I the only one who noticed that after version 32.0.101.5768 there is no more monitor overclocking on 11th generation Intel integrated graphics? I can't set 75 hertz on my resolution 1920x1200, tried all options, only rollback to 32.0.101.5768 helps.
MoBo MSi B560M PRO-VDH - latest bios
CPu Intel Core i5-11500
Lenovo ThinkVision T23d-10 - hdmi link
Windows 11 24h2 26100.1876
The problem appeared since version 32.0.101.5971

Is there an HDMI data block in the CTA-861 extension block? If not, the pixel clock will be limited to 165 MHz. If there is an HDMI data block, is the max TMDS clock higher than the pixel clock for the custom refresh rate? If not, the driver might ignore the custom refresh rate. Ideally it should be set to 340 MHz for HDMI 1.4.

What GPU? What data blocks are in the extension block?

Nvidia 4060 here's the extension blocks:

could it be related to this feature in display?

i have to point out that nvidia control panel reports the correct thing (only 180hz refresh rate)

Hi,
Apart from settings a higher refresh rate or messing with timing, etc. Can CRU physically damage a monitor? Like corrupt the EDID of a monitor and do irreversible changes?
Thanks

I'm thinking to use it to "delete" some unused resolution on my Aorus OLED 1440p monitor.

No, CRU doesn't modify anything on the monitor.

Does disabling variable refresh rate in the Windows graphics settings make any difference?

I reverted back to 23h2
