Custom Resolution Utility (CRU)

Do you know if it's possible in anyway to force windows to recognize this headless HDMI emulator as HDR compatible?

Did you copy and paste the extension block from the monitor to the headless display? I'm not sure if that will work because the HDMI emulator might need to report that it supports HDR for the driver to enable it.

Yeah, I copied the extension block from the LG B8 OLED TV. I see what you're saying, do you know if there's any way, if possible to get a HDMI emulator to report HDR support if possible at all?

Thanks!

So is there any reason why I couldn't just increase that to, say, 340hz in order to get more headroom for increasing the refresh rate? Would there be any other setting changes necessary in order to test this out? Essentially, I'm trying to figure out what the true reason is for the complete signal dropoff after 76hz; up until now I thought it must have been panel constraints, but this has me thinking it might be some pre-specified setting limitation by the manufacturer, since I'd expect there to be some artifacting prior to the signal become undetectable, or is this incorrect?

The range limits is informational and wouldn't affect what the monitor accepts. The refresh rate is restricted by the monitor's firmware. There's no way to override that with software.

Darn. So I'm guessing that means there aren't any real solutions to the frame rate cap? At least none for someone not super well versed in the area?

FreeSync monitors usually don't support higher than the maximum advertised refresh rate.

The only thing I can think of is if the HDMI emulator allows you to flash the EDID on it, you can try flashing the TV's EDID onto the HDMI emulator. There isn't an easy way to do this in Windows, but you might be able to do it with a Linux live USB and a tool like edid-rw. I don't know if that's enough to get the driver to enable HDR.

Hi! First time visiting and I've been trying to find an appropriate forum to ask this question/get confirmation of a hypothesis.

Im interested getting the new Radeon 5700 XT graphics card, partly due to their artifically improved performance by combining GPU Scaling & Radeon Image Sharpening without a significant performance loss (https://www.youtube.com/watch?v=7MLr1nijHIo)

In the video they use GPU Scaling to 1800p to simulate 4k graphics (~80% scaling) and then improve the picture by image sharpening to recreate a near indistinguishable picture compared to native 4k.

I have a 3440x1440 ~90hz screen so getting high/ultra graphics and stable framrate is a task even the 2070 Super would struggle with, so my thought is to get the 5700 XT (AIB-card) and then be able to use GPU Scaling/Image Sharpening as a "secret weapon" when extra performance is needed.

I am not familiar with GPU Scaling before, but is it possible to just modify the resolution that I wish to have scaled? in the movie they used 1800p but perhaps this was just a handily available resolution in the game to choose from. Am I able to easily customize the resolution to represent 60,70,80,90% of 3440x1440 resolution? So that Im not stuck with only scaling 2560×1080 for instance as that would represent a 55% scaling which is probably to much to not also be a significant quality loss.

Would the CRU be able to give me this customatization ability? Or is it already natively supported in the radeon tools?

Thanks for your time!

GPU scaling will scale any lower resolution to the native resolution. You can add any lower resolution with CRU and it will be scaled up if GPU scaling is enabled. CRU doesn't have percentage calculations, but you can easily do that with a calculator.

For 70% of 3440x1440:

sqrt(0.7) * 3440 ≈ 2878
sqrt(0.7) * 1440 ≈ 1205

2878x1205 is approximately 70% of 3440x1440.

Ah thanks for the response! So how does that customized resolution work in games? I.e. if i enter 2878x1205 in CRU, does that option pop up as available in all the games i play as well? Or do i enter 3440x1440 in the game and then CRU overrides that setting and downscales it?

Thanks again!

You would have to configure the game to use the new resolution. Many games use the same list of resolutions available in Windows.

So how would I make custom resolution or refresh rate with dual graphics in laptop? https://www.monitortests.com/forum/attac...hp?aid=413
