You probably created a GPU-scaled resolution for 2560x1440 while keeping the active resolution at 1920x1200, while CRU creates active resolutions that are sent to the monitor, and the monitor is telling you it doesn't support the resolution.
I'm pretty sure I never enabled GPU scaling (I only found out about that option
after adding the 2560x1440 resolution), but your tip to use DSR did solve the problem!
The resulting PPI is even close enough to that of my main monitor that I can use it for a decent triples setup.
Thank you so much for your helpful advice!
Hello, I was mainly concerned with increasing the native refresh rate of 60Hz of my Dell UP2516D to 80Hz and activating Freesync.
One issue I had was that 80Hz always seemed a little blurrier than 60Hz and even 75Hz, which happens to be a supported refresh rate in some resolutions.
But then I noticed instead of just adding refresh rates, sometimes one has to edit the "Display Properties" on the top, where one can change the Range limits. Arguably changing the V rate from 50-75 to 50-80 has reduced the blur (approximated to the normal blur of the monitor).
But I will have to test it a little more. (Maybe someone can mention if my assumption about this is wrong anyway.)
My main issue has been with Freesync. Some say, HDMI works best or only. I currently use the Displayport. I also don't see a guide for Displayport, but incidentally on that matter the original post mentions editing the Display Properties as I just said above.
Do I have to try the HDMI cable to see if turning on Freesync is possible?
But then I came across this random comment from 2015, and it makes me wonder:

*IF* This is a GSYNC monitor (the XB270HU), then read on.
Is this (still) true, Nvidia cards automatically exclude Freesync support? I'm quite sure this is incorrect, as I tried some Freesync monitors which definitely worked on my GTX 1070. I don't remember if they all showed a Freesync setting in the Nvidia Control Panel, but some did, I think. (And I had the bad luck that around the time Freesync monitors which interested me were slower than the Dell, which is more or less for image editing, but wide gamut was a priority for me too.)

The UP2516D is not a FreeSync monitor, and the range limits would not affect the image like that.
Yes, I'm aware it's not a Freesync monitor, but I thought one could include Freesync on non-Freesync monitors.
But it seems this is mostly for the HDMI-connection, for some reason, correct?
I didn't expect the range limits to activate Freesync, I'm just wondering why there are no instructions of activating Freesync via Displayport connection (as per the Extension blocks), which brings me back to my first point.
What I was saying about the range limits is just that possibly it enabled the monitor to truly produce 80 Hz, instead of some "fake" version (maybe limited by the range limits), which causes blur or rather some slight jitter. But I don't think this actually changes anything. Simply adding custom refresh rates in Detailed resolutions is enough (although the blur in 80Hz compared to 60Hz remains).
Could the other parameters, like Front porch, Back porch, or Total lines etc. possibly have anything to do with blur or jitter at different frequencies? (Everyone might know it from those half and quarter fps over at testufo, though I think to a lesser extent this also applies to different main frequency settings of monitors.)

No, I've only seen that work with displays without scalers such as laptop screens and those overclockable Korean monitors with DVI from 10 years ago. HDMI monitors almost always have scalers, so that won't work unless the monitor happens to have a scaler that already supports FreeSync. HDMI FreeSync is also AMD proprietary, so that won't work with NVIDIA. NVIDIA only supports DisplayPort adaptive sync and HDMI 2.1 VRR.

FreeSync via DisplayPort is built into the DisplayPort protocol as adaptive sync and doesn't use the EDID for anything other than the refresh rate range. There's no way to add FreeSync to a DisplayPort connection.

The range limits descriptor is informational only and doesn't affect anything except the DisplayPort adaptive sync range if the monitor supports adaptive sync. AMD also listens to the pixel clock limit, but NVIDIA doesn't.

No.
I am currently trying to teach my LG55B9 OLED a 21:9 resolution with CRU, of course with black bars at the top and bottom, pixel-perfect at best and 60hz is enough for me. But no matter what I do with 3840x1620 etc. I get the message that it is not supported by the B9. Using the Nvidia driver with desktop resizing etc. works, but unfortunately only with 8bit, which I don't want to use. Do you have any ideas how I can get a CR 21:9 resolution with 10Bit or 12Bit and also use HDR etc. @60hz? Greetings Ron
Hello,
I have a Philips 55 OLED 718 and i am trying to get FreeSync to work through a DP to HDMI 2.1 adapter. The VRR works when using an HDMI. But the problem is i have an 2070 Super that doesn't support 2.1. So i bought an DP to HDMI 2.1 and a 2.1 HDMI Cable.
The problem is, when i connect the TV to my pc, In Nvidia i can set 12bpc Full Range 120hz, but the TV only reads it as 12bpc Limited Range and the Colors become screwed up, this is one of the problems. To fix the colors i can set it to 12bpc Limited range and seems fine.
Now for the GSync part, i can enable GSync in NVidia Control panel for the display. The problem is GSync doesnt actaully work. I downloaded the demo from NVidia Website and tested multiple games the GSync logo never shows up even tho Gsync is enabled in NVCP.
I read online that in order to get VRR working though the adapter i have to make the PC send an HDMI VRR Signal instead of DP VRR signal. Since the TV is receiving a DP VRR Signal it doesn't even detect it. I assume its the same issue with Full Range RGB, the TV is detecting it as a Limited Signal for some reason even tho in NVidia its set to Full RGB and in the process it screws up the color. I read that this can be fixed using CRU. But i have no idea where to start.
If anyone has any way to help on what to change to get the Full 12BPC Full Range + GSYnc working i would appreciate it. I can also offer more info if needed.
Thank you.
I also made a thread here:
Sorry for double post, i will remove it if it is an issue.

This is what i found dunno how to do it:

Hello everyone. I have a QN700b 55' 8k Samsung tv that I am using as my primary display. So I am in a bit of a unique situation as I don't think this is a very common setup and I have not been able to find a solution for the problem I have been having. For some reason in the Nvidia control panel the "customize resolution button" is greyed out so I cannot try to add new resolutions. With the program CRU when I tried adding resolutions they do not appear in Nvidia control panel. Even upon inspecting with regedit in ->Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration editing the values here had no affect. Can someone please advise me on possible remedies for this? My main goal is to create a custom resolution of 7680x2610 so it would be selectable in various games, with this resolution I can have an ultrawide display with games running on it and two small windows at the top for productivity while gaming.
If anyone else here has white line flicker issue I mentioned in my earlier posts, please try disabling Hardware Accelerated GPU Scheduling and check again.
Edit: nevermind, just saw it again. just didnt happen for a lot longer maybe coincidence
Hi, I have two Acer monitors XV272U V. They are both capable of 2560x1440 @ 170hz. When I enable 170 Hz on one, the other one defaults itself at 60 Hz. After I manually choose 170 Hz on the 60 Hz monitor the other one defaults itself to 165 Hz. If I restart the PC the monitor with 170 Hz keeps its refresh rate, while the other defaults back to 60 Hz. In CRU i am not able to add the 2560x1440 @ 170hz res. Whenever I type in the refresh rate 170, it becomes red and it doesn't let me save it. I tried to copy the settings from DisplayID 1.3: 1 data block (that one has 2560x1440 @170 Hz), but it wont let me save it like this either. One monitor is connected via DP to DP and another one via DP to USB-C to my PC. Graphic card is a crappy Intel Arc (i5 13th Gen). Disabling or enabeling Freesync in the monitors OSD doesn't help either. Anyone can share some light in this issue? This will be greatly appreciated.
