I've made sure to use all the timings for the resolutions I'm trying to set but they either change nothing or causes some weird colors/flickering

Something I have noticed is switching to the PC mode in my picture settings fixes the issue. However, turning off the TV or PC, changing a picture setting causes the screen to move or overscan again. Meaning I have to switch to another mode and back to PC mode. I think what's happening here is the TV thinks it needs to be in game mode which messes with the TV overscan. PC mode seems to disable over scanning.

I have messed with the GPU scaling and display scaling options and it hasn't changed anything. Disabled HDR, enabled HDR makes no changes. Tried 30hz, tried RGB 8 and 10 bit. Tried the YUV 420 and 422. No changes

I edited the HDMI 2.1 data block (which is weird... TV only had 2.0 and so does the 1080TI) and removed ALLM which changed nothing.

That sounds like a TV limitation, but GPU scaling should work around that. 2560x1440 should already exist as a scaled resolution by default if 3840x2160 exists. This has nothing to do with 2.0 vs. 2.1.

Hi, I am using a Dell Latitude 5440 (support DP1.4 DP alt mode) to connect to my ASUS XG43UQ monitor (supports up to 4k 144hz) via a DockCase 8-in-1 smart dock. The dock equips with a PS186 DP to HDMI micro-chip, which supports DP1.4 input and HDMI2.0b output. I enabled the 4-lane DP alt mode in the dock configuration menu.

I set 4k refresh rate in Display ID 1.3 slots. The highest refresh rate I can get is 67.5hz. Any rate higher than that would not appear in the Win11 display drop down list. Looks to me it is somewhat related to 600MHZ pixel clock limits of the dock.
So, my question is - Is there a way that I can override this limit and force a higher refresh rate for my 5440?

Interestingly, when I connec the dock to my other Dell Latitude 5410 (supports DP1.2 alt mode), I can set refresh rate up to 75hz @4k. At this configuration, Win11 says it output @ 4k with 8bit RGB color, while my monitor tells me that it runs @ 4k with 8bit Ycbcr420. It looks to me that the PS186 in the dock converts 8bit RGB to 8bit Ycbcr420 (yes, PS186 indeed can do color space conversion).

The behavior on 5410 also leads me to think I probably can go refresh rate higher than 75hz on 5440. Because 5440 comes with DP1.4 and it has enough bandwidth to run 4k@120hz. And if PS186 can convert color space to Ycbcr420, it still has chance to output 4k@120hz on HDMI side without overkill HDMI2.0 bandwidth.

BTW, I did try 4:2:0 resolution in CRU. Doesn't work.

Thank you in advance.

Hi ToastyX,

I just went into my registry, and the NV_Modes key now has just this: {*}SHV 99999x99999=1 in it

There is another key called "NV_Modes.bak" which has a larger list in it with resolutions divided into sections SHV "resolutions"=1, =1F, =1FFF, =3F, =3FF, =7B, =7F, =7FF, =FFF, and S "resolutions"=1, =8032

Wondering if I can just can delete all this stuff and put in the resolutions by hand, and if I need to remove the .bak file, and/or should delete the 99999x99999=1 entry.

For context, I have 3 displays hooked up; 2 of them are fixed resolutions (1920x1200 and 1920x1080) and the other one is a CRT capable of displaying resolutions up to 1600x1200 in 4:3.

It looks like at least 1 resolution that is available in my Nvidia control panel is not present in the NV_Modes.bak file, so I'm thinking maybe the 99999x99999=1 entry doesn't necessarily refer to that key for it's list. Perhaps it tells it to poll Windows Device Manager or something?

Anyone have any recommendations. Thanks

That means you used SRE at some point and deleted all the resolutions: https://www.monitortests.com/forum/Threa...Editor-SRE

NV_Modes.bak is the default defined by the driver. 99999x99999 is a dummy resolution because NVIDIA's driver will ignore NV_Modes without at least one resolution in it, and 99999x99999 won't show up because it's higher than any resolution currently possible.

I don't know what you're trying to do, but you shouldn't need to edit the list by hand if you're using SRE unless you want to set the refresh rate bits, but that only applies to non-PnP displays.

That sounds like a graphics driver-imposed limitation because DisplayPort 1.4 HBR3 should support up to 1080 MHz pixel clock at 8 bpc. If there are HDMI data blocks, delete them since they aren't needed for DisplayPort. If the range limits is included, set it to 1080 MHz. The driver might be listening to one of those.

Thanks. That makes total sense.

I'm trying to troubleshoot an issue with DOSBox Staging (which uses SDL 2.0) where it's not properly displaying resolutions above 640x400 on my monitors unless I explicitly force them, which is a pain in DOSBox because the console is almost always a different resolution from the game you are playing, and some games switch resolutions in menus.

I thought maybe Staging was looking at the NV_modes list for resolutions, but that didn't really change anything for me.

Now I'm thinking maybe it's something to do with Standard Resolutions vs Detailed, but I'm getting a bit lost trying to figure it out. For one thing, I absolutely can get all the resolution to appear as long as I force them, it's just the switching around that seems to bork things.

I also am not using any extension blocks for anything other than my projector. For my CRT, I have 640x400 and 800x600 as detailed, and the rest as standard.

For the sake of simplicity, I'm just trying to get Blood and Quake to both run in 800x600, which should be fairly simple. DOSBox opens in 640x480 and then it jumps to 800x600 when the game launches. Staging is then downscaling the image to 544x400 and displaying it in the lower lefthand corner of a 800x600 fullscreen

I can appreciate if this is something you wouldn't know how to investigate, but I haven't had any luck from the Staging folks because it seems to work fine on their setups, so if you have any ideas (especially ones related to CRU), then I'm all ears

Thanks

Tried both suggestions, no avail. Still don't get the refresh rate in the drop-down list. Anything else that graphics driver may be listening to?

BTW, I suspect that the dock may pass 600MHZ pixel clock limit to the laptop, because it only has a HDMI2.0 downlink port although it has a DP1.4 uplink port.

Hi, guys.

I need help, for several days I've been trying to set up one computer with a GeForce 3050 and two Optoma 1080p projectors. They are connected via DisplayPort. Each projector has a resolution of 1920x1080, but when I enable Surround, I only get a single resolution option of 8192x3840. While working with CRU , I managed to achieve a Surround resolution of 3840x1080 (which is what I need), and everything works great. However, when I restart the computer, the second projector never turns on, all settings reset, and Surround sets the resolution back to 1920x1080. Guys, I'm asking for help, I've tried everything already, can anyone assist with this issue? How do I make sure that upon restarting, the second projector turns on?

hello i recently bought a 360 hz alienware monitor and i cant set the cap the 360 hz in extension blocks and native resolution. does cru work with 360? if so tell me how to fix this please

I have no idea what you're talking about. You need to be more specific. What exactly are you doing?
