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

What happens if you try adding 1920x1080 @ 61 Hz? If the refresh rate isn't listed, try using the "Copy" and "Paste" buttons at the top to copy everything to the duplicate monitor entries in the dropdown list. If that doesn't work, try rebooting instead of using restart.exe. If that still doesn't work, then the driver isn't allowing EDID overrides on your laptop for some reason.

Will you support Navi graphics cards? I still use my QNIX 27" 1440p but was thinking of getting a RX 5700 XT and Ryzen 3600 build. I was thinking a dvi-d to hdmi or DP cable might work? If not then, nm, but if that cable does work, it would be nice to keep using CRU and Patcher for my 110hz overclock. If too much work for you since it is a new GPU design, no worries at all, cheers

CRU doesn't deal with the GPU directly (except to read extension blocks), so it will work with any driver that supports EDID overrides. The patcher will depend on how the driver handles limits, but that monitor needs dual-link DVI to reach 110 Hz. Most adapters are single-link, and that monitor can only handle around 60 Hz with a single-link connection. This is the only dual-link adapter I know that can handle higher pixel clocks, but AMD's driver limits it to 300/400 MHz pixel clock at 8/6 bpc respectively: https://www.amazon.com/dp/B00856WJH8/?tag=mtests-20#ad

Instead of using an adapter, I recommend waiting to see if a non-reference 5700 XT comes out with a dual-link DVI port. MSI is coming out with some custom cards soon.

Got it. That's worth trying. I'll let you know if it works.

Thanks!
