And it works , I can use 2560x1440 at 175 hz. It's selected and applied right now currently with this cru setup, and when not using cru I obviously could select it too , but even when using it to change my native resolution I can choose 175hz.

However only when I remove the 3440x1440 resolutions or change them. Then I can't use said refresh rate.

Am I missing something? Why am I always able to use 2560x1440 at every single hz the monitor comes with UNTIL I do the specific cru action of getting rid of the 3440x1440 resolutions that are attached to said refresh rates?

Thank you for taking the time to respond

Also unfortunately having my native resolution at 2560 isn't enough, I guess nvidia chooses the silly route of basing dldsr off your max resolution not your native.

Would you know any way I could use your program to get around this?

If you have GPU scaling enabled, then all lower resolutions are always scaled by the GPU to the native resolution regardless, so all refresh rates at the native resolution will be available at lower resolutions since the monitor is actually receiving the native resolution.

If you have GPU scaling disabled (display scaling), then any resolutions defined in the EDID as shown in CRU will be sent to the monitor, and any scaled resolutions automatically added by the graphics driver will be scaled by the GPU to the next highest resolution.

In either case, the native resolution is never scaled, so when you delete 3440x1440 to change the native resolution, 2560x1440 is then sent to the monitor instead of being scaled by the GPU, so it will only work at whatever refresh rates the monitor supports at 2560x1440, which happens to be 60 and 120 Hz. There's no way around this since it's a limitation of the monitor.

The Windows advanced display settings will show you the desktop resolution and the active signal resolution. If the desktop resolution is 2560x1440 but the active signal resolution is 3440x1440, then it's being scaled by the GPU. The monitor should also report what resolution and refresh rate it's receiving somewhere in the monitor's menu. It will report 3440x1440 if it's being scaled by the GPU.

That's such a shame. Thanks for taking thentime to fill me in have a good one!

Can you tell me how I can reach the maximum frequency of my monitor? I was able to increase the frequency of my BOE08BE PnP 120Hz monitor to 132.40 Hz using the mode: Exact reduced

Hi, I recently got me a QN800B Samsung for double use as TV, but mostly as monitor (95% of the time). I use it with a 1050ti Nvidia videocard.

It is 'only' 65" big so when watching 8K it is the same as staring to a 32" 4K monitor up close (yeah, pretty stupid). So was looking for a way to change the resolution to 5K 5120x2880 or 6K 6400x3600. But no matter what I've tried, I can do anything from 3840x2160 downwards, but can't find out how or if it is possible at all to show resolutions between 4K and 8K.

Are there safe ways to get there? (blew up my PSU and MOBO died recently after black screen followed by hard shutdown, after messing with resolution settings).

(btw, my advice: stay away from 8K for the time being, as the technology and ecosystem is not ready yet, the things you have to perform to make the screen show 8k content are just ridiculous, messing with 'game mode', 'extra signal', '4:2:0 YCRB' and other trickery)

Hope this isn’t a rule breach but just wanted to say, since you resolved my issue with the monitor, which now allows me to use DLSS and NIS correctly on games, I have been enjoying HZD, RE4R and Crysis Remastered maxed out!

Honestly, you and your tool have improved my gaming experience substantially and I sincerely appreciate it mate.

Now back to some correctly scaled games

I have an LG C2 Tv for my pc monitor. When I add custom resolutions through the nvcp, it won't let me use HDR when using the ultrawide function of the TV using 39=840x1600 or 3840x1080. Someone said I had to create the custom resolutions via CRU to correctly use HDR. For some reason using the nvcp won't let me use HDR after doing all of this.

So I ask you, what is the correct way to add two resolutions to my nvcp via CRU? I want to add 3840x1600 120 hertz then I want to add 3840x1080 120hertz. Apparently creating the resolutions through CRU will get HDR working instead of going through my nvcp.

How do I do this in CRU? Thanks a bunch!

I figured it out. All good.

Thanks everyone.

I'm using a Lenovo ideapad slim 5 (Intel Iris Xe graphics card with the latest driver updates) with an HMDI to an LG 34WR50QC monitor (https://www.lg.com/us/monitors/lg-34wr50...-monitor).

No matter what I try, including CRU, I cant get windows to display the resolution of my monitor (3440 x 1440).

Can someone help or run me through the step? Thanks.

You need HDMI 2.0 for that resolution. Use USB-C to DisplayPort instead.
