That's the same as using CRU, and CRU can export .inf files too. It must be a bug in the driver. Does switching GPU scaling on and off make the resolutions appear?

Switching GPU scaling on and off appears to have no affect on this issue.

I checked the registry. CRU appears to be creating an EDID_OVERRIDE for the specific port of the W5700 that the XV273K display is connected to. I can move the XV273K to each port and create a unique EDID for each (different display name for each port). CRU lists the EDID for the current port as active. It also lists the EDIDs for the other 5 ports (not active).

Each port of the W5700 has a different "device instance path" that the display uses (viewable in the Device Manager device properties for the display). The system (and CRU) seems to think that the Device instance path is the same whether the display is connected directly to the W5700 or to a MST Hub connected to the same port. Maybe the AMD driver disagrees with that device instance path when the display is connected to an MST hub?

The device instance path points to the registry under this path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum

The device instance path for port 1 is:
DISPLAY\ACR06B1\7&aeaadc9&0&UID1024

The device instance path for port 2 to 6 are similar but replace 1024 with these numbers: 1028, 1032, 1036, 1040, 1044

CRU's EDID_OVERRIDE is under each device instance path at:
Device Parameters\EDID_OVERRIDE

CRU appears to be able to export an .inf file that might (I haven't tried it yet) apply to the display no matter what port it's connected to but I don't know how to install it since it gives an error "The third-party INF does not contain digital signature information." I wonder if CRU could be made to export a .reg file that I can import with the Registry Editor?

If there is a registry path that applies to the display no matter the port it's connected to, then wouldn't it be useful for CRU to be able to edit the EDID_OVERRIDE there (without having to use .inf or .reg)?

There isn't a path that applies to all instances. You have to disable driver signature enforcement to install an .inf file without a signature. I have instructions here: https://www.monitortests.com/forum/Threa...-inf-files

What I've found out is that for some reason, I am unable to add any Detailed Resolutions to the registry at all. Whether it be in the "Detailed Resolution" section or in a CTA-861 block, attempting to add any refresh rate at all (in my test case, 2560x1440 @144 Hz, Automatic PC Timing) in either block leads to a permanent black screen, which leads me to manually boot into Safe Mode.

Is the computer locked up when you get the black screen (does the caps lock light work)? Try deleting the HDMI support data block in the extension block.

Guys I have a laptop with Ryzen 7 4800H CPU (so integrated AMD GPU) but CRU does not work whatsoever while I'm using this GPU. Whenever I switch to Nvidia GPU, it works. So integrated AMD GPU is not supported?

Integrated AMD GPUs work when it's the only GPU. I haven't seen a system with AMD+NVIDIA switchable graphics, so I don't know if that works. Usually it's Intel+NVIDIA.

From what I remember, the CAPS lock light still did work when the screen when black. I just had no screen whatsoever.

Could the HDMI data block be interfering with DisplayPort output? I'll delete the HDMI block and get back to you.

Got it. The silly HDMI data block was the issue. I now have all of my refresh rates I need for my display. Thanks again.

Scratch that, never mind. Now nothing launches, and every time I launch an executable to fullscreen outside the desktop, my monitor states that the timings are incorrect for every resolution I have and shuts off. This includes the stock refresh rates (60, 120, 164) that came with the monitor.

I have tried setting the Timings in CRU to PC (Automatic), but considering how everything was working before and now doesn't, it shouldn't have an effect, and predictably, it did indeed do nothing. ****.

What hardware? This is usually a driver issue.

I've tried to figure out what monitor I have but it isn't giving me any details on that in device manager. I have an RTX 2060 (probably mobile version) and an i7-9750H.

For the life of me, I can't figure out what settings I need to change to make this work

What are you trying to do with CRU? Laptops with Intel GPUs usually have switchable graphics, so Intel's graphics driver is responsible for handling the monitor.

All the resolutions I tried through both Intel & Windows interfaces are blurry, as well as the custom resolutions I tried through Intel. CRU is the only thing I've found that changes the res but stays crisp (even if only for a second).

But more importantly I need this because I find my laptop screen is too small for its native 1920x1080, but the next smaller res is 1680x1050, which is too big. I've narrowed down my ideal resolution to 1840x1035, which is an awkward number... but if I can figure out the right settings in CRU, I'd be set for life lol.

Also, just want to say major kudos to you for still answering questions almost a decade after posting CRU. That is rare indeed

Hi guys,

I just bought a new monitor (Iiyama GB3466WQSU). This monitor should have a native resolution of 3440x1440, but I don't see it in Windows 10.
I tried this tool and it shows me the native resolution of the monitor as soon as I open the tool:
   

Do I need to do something to make it visible in Windows?
Because there it doesn't show me:
   

Many thanks!
