Nvidia Change Resolution

[Jomega Gibson]

Hicuriouser,

I think this issue happens because vnc server cannot support xrandr. The current resolution is default 640x480. You could check if latest vnc server support xrandr. I have tested some usecase.

The standard VNC server vino of Ubuntu 14.04 does not support xrandr to change screen resolution on a headless system. There are several ways how you can cope with that problem. One way is to install another VNC server like vnc4server, which support display resolution configuration with xrandr.

FYI, if a hotplug event is detected and the EDID of a monitor is successful, then unplugging this and plugging in another monitor without EDID will likely result in the resolution sticking to what that previous monitor was set up for. Even a virtual display might inherit a successful EDID query of a real monitor, and if the real monitor was never there, then perhaps initial default timing is failing.

I am using Isaac Sim 2023.1.0 from a docker container and use WebRTC to visualize it. Changing the width/height of the [settings.app.window] within omni.isaac.sim.headless.webrtc does not seem to affect the stream resolution. Is there a was to change the resolution?

For me, it seems like it fixed whatever the browser window size is (websocket was adapting to browser size previously, but I do not see the same behavior with webrtc). Could you check the behavior and confirm, please?

Actually, I noticed that while this works to scale the window size, the resolution does not scale, so the view looks blurry with a bigger size. Is there a way to scale the resolution as well so it looks sharp?

Whenever I try to change my resolution on my PC away from the default resolution (1920x1080), after a few seconds it keeps changing back.Still happens if I use the nvidia control panel to change resolution or the windows settings.Any idea how to solve this?This only started happening after I recently reformatted my pc, as I used to do this all the time.

Maybe your GPU driver is continuously trying to recover the optimum resolution for your display (while you're not playing). I suggest you checking your Nvidia GeForce setting and look for something like that. If you found it, disable it.

I keep having trouble getting the correct monitor resolution - every time I reinstall, I happen to use a newer Ubuntu release and the old tricks I used to know no longer work. Instead of leaving a long trail of questions for every new release, I am looking for a more universal and timeless solution.

Note that steps 6 and 7 are not usually necessary; try skipping them and if that does not work, repeat all steps and include these two. Some monitors don't send EDID information to the computer, so Ubuntu can't know what the monitor is capable of and only offers safe (low) resolutions. Those two steps resolve that problem.

Click "Save to X configuration file". Here I had some difficulties with saving file, despite running nvidia-settings as root and trying to save in places I definitely had right to write.

I've finished my install of a Arch Linux base system and everything is working fine, no errors found in the the systemd journal nor systemctl. I've installed the display server Xorg via the package xorg. Then I decided to install the graphics card drivers. As I'm running the GTX 1080 I figured I should install the nvidia package. Then after reboot the resolution didn't adjust for my monitor so it stays at a lower resolution, which makes text uncrisp and big.

Hello I have just installed tumbleweed. I am quite new to Linux and have followed everything as on guide while installing the drivers. When I use amd(integrated) gpu my screen resolution looks fine (as it should be) but when I change my bios settings discrete (I am not even sure if they will be switching automatically if I keep my settings on Dynamic!) my screen resolution drops a lot, in settings it says 1920 to 1080 but I think it is 1280 to 720, and I could not find any way to fix this so I am asking for help.

Thanks in advance.

I have recently bought a dell G15 5520 and I am trying to make a custom resolution but I cannot change the resolution in either Nvidia control panel or Intel control panel, when I try to look up fixes for this problem everything says I should be able to change it in either one or the other but none of the options to do so are in either program for me. please help me out this is really frustrating me

I'm having the same problem for a few days now, it was working fine until this last sunday.

I can't change the resolution it even in Intel Graphics Command Center as you said.

I've tried adding a custom resolution but can't change the aspect ration as you can see below:

I have a fresh install of fedora on disk (no VM) of the latest version fedora 38 with KDE plasma.

Originally I was running my display with a native resolution of 3840x2560@60 off of my intel iGPU without any issue.

I verified that both generated grub.cfg files contain the resolution. I even added fake 40_custom entries to make sure I got the right file. Booting into grub my changes to 40_custom are visible so I guess it is working as expected.

However the modes file still only shows 800x600.

there is a little star near the resolution (preventing me to change it ?) in display setting it doesn't give me any other option, i'm currently in 800x600 (4:3) and my screen is supposed to be in 1920x1080.

Your nvidia driver is not set up properly, thats why you can see or access other resolutions. Unfortunately, I don't have any experience with nvidia drivers. We can wait to see if anyone else does and responds or you can ask on your distro's forum for assistance.

I just replicate the same think on Devian same problem, someone on a another forum told me that i have multiple drivers installed, i realized that in the panel of installation (when you first use Peppermint) i have let Peppermint offer me a program to automatically install graphic drivers, using only the minimum with this panel i could have (in my case) a decent resolution, but some graphics program didn't work at all and giving me error report

But, before that, can you set a new resolution in KDE Plasma System Settings > Display and Monitor > Display Settings and does that survive reboot? If not, did you try with a new session instead of a saved one in Settings > Startup and Shutdown > Desktop Session

Open the graphical Nvidia Settings and set up the Layout with the proper resolution. From the Preview menu, copy that text and add the important part to /etc/X11/mhwd.d/nvidia.conf

Or if you are unsure, then share it here and i will prepare it for you.

I do not have any options for screen resolution settings. It defaults to 2560x1440 @ 240hz on a 15.6 inch laptop display on X11 and Wayland sessions. Is this a feature, bug, or something that can be configured?

It maybe possible to instruct more modes to single nvidia mode, if you get/copy them from your hybrid setup Xorg log (/var/log/Xorg.?.log) and insert them in a Monitor Section, in a conf file at /etc/X11/xorg.conf.d/, following some examples at Archwiki.

I'm not sure how to go about getting Nvidia DSR to work. This is on a 1080p monitor. My goal is to get the gauges to display a little more clearly if possible. I set DSR Factors to 4.00x (native resolution) which in turn automatically switched DSR - Smoothness to 33%. This is all I've done so far.

Do I need to switch the in game resolution to that of a 4k monitor? I think I tried that but then only the top left portion of the game menu was being displayed. Also, I've got a fast rig with a so-so video card, a GTX 960, so when I get this to work maybe I should be setting DSR Factors to 2.00x?

Thanks Falcon. That seemed to work as my usually butter-smooth framerate took a noticeable hit now with DSR enabled and running 4k resolution in game. It did not make the gauges any clearer so I guess I will just have to zoom in for now.

do not switch to 4k. it will drop ur fps. 1440p is the max u shd go. once u have activated ur dsr in nvidia, change ur resolution to 1440p. the text and game objects will get smaller so u will have difficulty tracking targets.

Now, I am aware of the limitations of Nvidia driver support under XP (Displayport 1.1 and HDMI 1.4 (?) IIRC), but I don't believe that excuses this... obviously false identification of my monitor under XP. However, there seems no obvious way to remedy the situation, and so I'm asking you guys if any of you know of a way to manually change my monitor type (e.g. registry and/or config file edits).

The latest XP drivers of NVIDIA are broken in this sense. This problem is not port specific, monitors using DVI looks the same. Actually they are not detected as CRT, in case of proper CRT detection with working drivers you do not have connector menu (composite or s-video) or TV-format selection (NTSC/PAL). The biggest problem with these buggy drivers is that custom resolution settings is grayed out. But you can add custom resolutions by editing the registry:
