Hi, first post here. I've used CRU in the past to get some more out of some laptop monitors I've had. I'm trying now on a desktop screen (HyperX Armada 25). Default clock is 240hz and I'm unable to even go 1 hz above that. The screen displays a message that the input signal is out of range. I'm wondering if this is something that the firmware is blocking since I find that hard to believe, so maybe there is nothing I can do, but hoping there might be something I can try?

Thanks.

It's common for firmware to block higher refresh rates, especially if the monitor already supports high refresh rates. Laptop screens are different because they normally don't have scalers, so there is often nothing blocking higher refresh rates from being sent to the panel, but the panel controller can't always handle higher refresh rates, and you're still limited by the bandwidth of the interface.

ok, so I guess I'm out of luck on this display. Thanks for responding, and thanks for all your work!

Hello there! hoping for some help as I do struggle figuring out whats going on here.

I am trying to make freesync work on a BenQ XL2546, the monitor is hooked via HDMI 2.0 to a laptop which has an iGPU (VEGA Ryzen 5000 series) and does recognize the monitor as a VRR capable monitor.

However when enabling VRR it will black screen on any game or application, it will work fine if VRR is disabled on the AMD driver, furthermore it did work for a random and brief time (around 2 hours) until I decided to launch CS2, which then completely broke it again.

Not sure if I am missing something. Thanks for reading! Smile

Is that happening only on the laptop or does it work fine on other systems? Try unplugging the monitor's power for a minute to reset it. If that works but then it happens again, the monitor is defective.

Hi! Question about my unusual setup: GPD Win Mini Windows 11 x64 handheld gaming PC (AMD 7640u) + USB Type C out (with Display Port signal) > StarTech Type C to VGA passive adapter > Sony PVM 14L5 (with a VGA input clone card). I can output 640x480p 60hz just fine, it works great in RetroArch, super smooth.

Now, I'm trying to get 640x480i 60hz to work. My goal is to use other PVMs that only supports 480i.
I have added the resolution with CRU, but can't find a way to set it in Windows 11. Only 640x480p is ever mentioned as minimum - no interlaced options.

Is there a way to get 480i to work? Thanks!

AMD RDNA GPUs don't support interlaced resolutions, and AMD/NVIDIA never supported interlaced with DisplayPort signals either, only HDMI.

I havent tried other systems yet, will see if I can find something. Unplugging power does nothing unfortunately.
I don't know if its possibly a bandwidth problem? or is there anything I can do aside from adding freesync range?

You shouldn't be adding a FreeSync range. It should already exist if the monitor supports FreeSync. If 1920x1080 @ 240 Hz works without FreeSync, then it's not a bandwidth problem.

I guess I may have formulated myself badly, the monitor does not support freesync out of the box, at least not for HDMI. I'm trying to add freesync functionality to it, when adding the range, it detects it and I can enable VRR which doesn't quite work Smile
