My TV is a Samsung RU7100 65.
It's HDR is low tier and i want to Completely disable it in Windows 10.
How to do it ? sorry for that, i just don't want to mess with it and do something wrong.
Hey there guys ^^' Sorry about that.

Yes, edit the CTA-861 extension block and delete any HDR data blocks.

Wow, it worked. Thank you very much for this. Sorry my english.

I have a Lenovo laptop with integrated graphics when I attempt to downscale and increase refresh rate the screen goes black. I know this is an issue with limits for integrated graphics however, I was wondering if you knew any workarounds for laptop users with intel integrated graphics as going to 62hz on 1920 causes issues.

Thank you for your time!

Laptops don't have scalers, so the only way to add other refresh rates is at the native resolution.

Hi.
I am using VGA monitors (X224W) which goes up to 1680x1050 with DP to VGA "el cheapo" adapters. Thanks to CRU it it working, i had to copy the setting from the monitor connected to an other PC with VGA output.

I am using RX470 AMD GPU.

Now i have one last problem, in the screen resolution dialog from window 10 it still shows 1920x1080. It is not supported by the monitor, deleted in CRU. I think it may be supported by the DP to VGA cable. How to remove this resolution?

To explain why i need to remove it, i want to use eyefinety 3 screen setup where the central monitor have 1920x1080 (or more) and then eyefinety changes the resolution of side screens to 1920x1080 which is not supported by the side screens and shows "OUT OF RANGE".

Hi,
Thanks to CRU I am able to get Windows to use the other resolutions my 4K Smart TV supports, including changing the active signal resolution to match chosen desktop resolution and unlocking the HDR on 1440p , so thank you.

My one last final problem is, how do I prevent Windows from force loading their PNP generic monitor driver/prevent it forcing 8 bit bpc 60hz after every reboot?

the EDID of the TV using CRU and Advantiv EeditZ shows it only supports 10,12,16 bit bpc. makes sense because when it is on 8 bit bpc, the HDMI gives on screen green lines and other flickers and artifacts.
I have tried changing all detailed res and HDMI res to be 64hz and removed all 60hz, and even manually selected 10,12,16 bpc with both sets of software and restarted the drivers using CRU.
The current workaround is I just change in the win OS advanced display settings from 60hz to 64hz and the display changes back to the 10bpc custom driver set by CRU

The TV is Chiq U43H10 but it lacks a data sheet online or even PC drivers

Any ideas?

Hi,

I have 3 32" monitors connected via DP to my PC, now i want to use these 3 monitors in surround, which works, but only at 4k, is there a way i can make it possible with CRU that i can use these 3 monitors in surround at a lower resolution like 1080 or 1440?
I looked at the extension block should i delete the 4k resolution in detailed resolutions(second resolution is 1440p)?

Thanks!

You can add the resolution you want as a detailed resolution on all three monitors. If the resolution already exists, make sure the timing parameters match exactly on all three monitors. You can delete higher resolutions if you don't need them.

That question doesn't make sense because the "Generic PnP Monitor" driver isn't causing the resolution to change, and there's no such a thing as a TV that doesn't support 8 bpc because 8 bpc is always supposed to be supported with HDMI. Windows boots to the last set resolution if available, so this would be a bug with the graphics driver.

The monitor should have worked with the adapter without making any changes with CRU. Was CRU blank when you first opened it? Is the monitor detected as a "Generic Non-PnP Monitor" in Device Manager? That would indicate the driver couldn't read a valid EDID from the monitor, which means either the cable or adapter is not letting it pass through, or the EDID is corrupted on the monitor. AMD automatically adds 1920x1080 in that case.

Check the Windows display settings > Advanced display settings > Display adapter properties > Monitor tab and try enabling the "Hide modes that this monitor cannot display" check box.

The X224W supports DVI, so it would be better to use an HDMI-DVI cable/adapter instead of a DP-VGA adapter that converts the signal. If you don't have an HDMI port available on the GPU, then a DP-DVI adapter would be better. Then you can avoid VGA altogether.

Okay so this is a continuation of this thread:

https://www.monitortests.com/forum/Threa...1080p-48Hz

With CRU; I managed to add several refresh rate to my Asus VH222 1080p monitor, namely: 72Hz, 50Hz, 48Hz, 45Hz and 42Hz. The monitor bottoms out at 42Hz and doesn't want to go below that.

In case you're wondering; I can't stand screen tearing so I play with capped frame rate + "low-lag" vsync enabled by using this nifty technique that brings down vsync lag just 10ms shy of Gsync and works like a charm:

The problem is; whenever I go 45Hz or lower; the screen shifts to the right hand side of the monitor as seen here:

Is there any solution to this strange behavior?

Thanks!
