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.

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!

That means your hardware doesn't support the pixel clock required for the resolution. This is usually the case with laptops that have Intel GPUs. If you can use DisplayPort, use that instead. If not, try adding 3440x1440 @ 56 Hz.

That's not the same problem. Laptops usually don't support non-native resolutions without GPU scaling. See if Intel's graphics control panel has scaling options.

The monitor might not support other refresh rates, but I don't see why that would affect the stock refresh rates. All I can think of is it might be related to FreeSync, but FreeSync is supposed to use the refresh rate you set as the base. Maybe it's an NVIDIA driver bug.

I'm not sure which driver is responsible for the brightness but it might be Intel's graphics driver. Windows update might have updated the driver to a newer version that has the problem.

Thx for the quick reply! I ordered a USB-C to DisplayPort cable yesterday. Should arrive today. I'll keep you posted!

Hello,

The software works fine on my pc, but when I shut down the pc and turn it on again the screen resolution configuration returns to the basic one and not the one I had configured in the software and a parameter graphic.

When I restart it stays, but when I stop the pc and turn it back on it doesn't stay.

Can you help me please ?

I use a HDMI cable.

Thank you in advance !
