Custom Resolution Utility (CRU)

[AVIDummy]

Hello, I'm wondering if the CRU utility can help me. After my 32 inch monitor went dim I upgraded to a 40 inch 1080 display but instead of getting more screen real estate everything has only gotten bigger. I'm wondering if there is a way to scale everything down so it appears smaller. All windows 11 settings are already at their extremes. I updated the graphics driver but there is nothing in the software to help.

My onboard graphics says it will do 4096x2160 @ 60hz (depending on CPU, which is i9-14900K with 128 gb ram) . I have a DP to HDMI that has 8k printed on it.

I look at the CRU utility and I don't know what all the settings mean (front porch, back porch, sync width). Before I struggle to learn more I was wondering if you think there is a chance I my monitor will display a higher resolution or if I should buy a 4k monitor? The problem with buying a new 4k monitor is they are either really big (aka 43" tv) or too small or super expensive.

It seems like it should be possible to make everything smaller without changing resolutions. Should I look into graphics cards that come with utilities that fool the monitor? What are your suggestions?

Thank you!

I added a new detailed resolution of 2560x1440 @ 60hz (241.7 mhz) +/- and it works. I can't believe it. Now the problem is everything is a bit too small and the text is blurry but I'll play with the scaling and fonts then see. Pretty incredible utility you made! I wish I knew more about how to use it.

Thanks a lot for the information. That's a shame.

AMD has Virtual Super Resolution (VSR) and NVIDIA has Dynamic Super Resolution (DSR), which can scale 4K down to 1080p, but Intel doesn't seem to have an equivalent feature. CRU can only work if the display itself can scale down. The problem with scaling down is text will look bad, as you've seen. The timing parameters are not important. Usually one of the automatic options will work if the display supports the resolution. The first post has a link that defines the timing parameters: Timing Parameters Explained

Hello,

I've been using CRU for a while on my 240hz monitor but i recently upgraded to a 360hz Alienware 2523HF and i cant figure out how to do it, is there any chance i can get a detailed explanation on how to do it? my GPU is a 3060ti, thanks.

Hi! When using a Philips Oled 2024 TV (55OLED809/12) connected via hdmi 2.1 to a PC, there is such a problem that when the TV is turned off, every hour (constant) this display reconnects to Windows (with the appropriate sound of the device connection, but the most problematic thing at this moment is the system freeze for 3 seconds) when the TV is turned on ( doesn't matter what happens on it) there is no such problem, but it is worth turning it off, it is redefined hourly in Windows. I've already tried everything possible, installed a clean Windows, reset to default settings TV,updated the TV firmware, turned off all possible energy-saving settings in both TV and Windows, turned off the HDMI-CEC on the TV, deleted the drivers via DDU, turned off HDCP, rearranged the hdmi cable to different TV ports. Nothing gave any results, anyway, if the TV is turned off, it reconnects every hour, and several device setup manager event 131 errors occur at the same time when viewing Windows events. When searching for a similar problem, I found no solutions except how to disconnect the hdmi cable from the TV or de-energize the TV itself (this naturally gives the result, since the TV disappears from the devices in Windows completely and no longer reconnects), but this solution is not very convenient. Of the options that could solve this, it is most likely to connect the TV via a DP adapter to HDMI, but with this connection, the VRR will most likely stop working. So, maybe someone knows at least some solution to this problem, or maybe something needs to be turned on/off in the HDMI 2.1 settings in the CRU? Before that, I used a cheaper cable that worked poorly at 48 Gbps (the picture disappeared at a random moment, I solved the 40 Gbps limit in the CRU) I thought there was a reconnection problem with the TV turned off in this cable, but no, by buying a more expensive cable that works fine with standard settings, everything is the same. I used Windows 11 23H2, and also tried to upgrade to 24H2. RTX 4080 graphics card

That's a firmware issue that Philips needs to fix. The only way around it is to use an EDID emulator.

How to do what?

Forgive me if this has been answered elsewhere, I have done a lot of searching and come up with nothing specific.

I have been using CRU for probably 15 years now (I love it!), so I'm pretty familiar with it.

I currently have the following setup:
Windows 10 Pro 22H2
Gigabyte Aorus Elite X570 + Ryzen 7 5800X3D
Asus TUF RTX 3080 10GB
Nvidia 537.58 Driver (running this old version for testing, but later ones have the same issues)
Dual matching monitors:
2x KTC H27E22 (240Hz 2560x1440 FastHVA, Freesync\Gsync compatible, connected via DP 1.4 with name brand cables; one display in landscape, one in portrait)

Since going dual-monitor a few months ago I have noticed that if I make any changes to their configuration with CRU (deleting an unwanted resolution) and leave both displays enabled when I reboot, I will almost always get stuck at a blank\black screens with a hung startup (keyboard LED toggles don't even respond) right when the login screen should be showing.

It is normal to get stuck at this point when setting incompatible resolutions, but I have never seen this happen when simply modifying ANY resolutions with CRU. It seems very odd and it is a bit frustrating since there are some changes I need to make to my setup that only CRU can do.

This is a 2024 model of monitor, and despite the lesser known brand name these are absolutely fantastic displays (FastHVA is a sight to behold for those who hate IPS glow), so I hope it isn't just a display firmware problem. I am inclined to think it is display driver or even CRU related... as if some kind of incompatible data is being presented to the displays.

If anyone has any suggestions, please let me know.

If there is any extra information I can provide to help diagnose this, I will do so ASAP. This monitor has lots of extension blocks, and data blocks within them: DisplayID 1.3, CTA-861, HDR, Colorimitry, etc. Maybe something there is getting messed up in the process of trying to save\apply the edits from CRU, and the monitor is freaking out when it tries to load at startup.

... but again, it seems to mainly happen when both displays are enabled. It never ever gives a black screen when I delete\reset the changes from CRU.

Thanks for your time everyone.

This is an NVIDIA driver bug. I've been telling people affected by the bug to report it to NVIDIA, but it's been almost three years and they still haven't fixed it. The problem only seems to happen with multiple monitors connected, and even then it doesn't always happen. It's not an issue with the monitor or anything specific in the EDID. It happens when any EDID override is present.
