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?
