Cannot change resolution

[DanAE111]

After moving my system from a 1280x1024 monitor to my TV I cannot switch the resolution to something more suitable e.g. 1280x720 the system is stuck on 1280x768 and when not on the desktop the picture in steam is squished to a 16:9 ratio the system is assuming I'm using 4:3.

Doesn't happen when I use HDMI rather than VGA

Same thing is happening on my setup. If I connect my pc to my older 1080p monitor I get the full 1080p resolution (with DVI connector) but when I connect it to my HDTV (using a HDMI connector) I get only 1024x768.

Would be nice to have an option in the settings so that resolution can be set manually i think.

What you could try is power everything down and unplug everything just for a minute or two. Plug everything back in but make sure to power up TV before powering up PC. This may allow EDID to be detected properly so better chance of appropriate resolutions. This used to work on older hardware and not sure it will work but may be worth a go.

It may be more likely to be gpu driver issues. Just be patient for updates. Opt in to beta repos for latest updates.

EDID is read during the startup of X, telling someone to pull the power for an extended period of time is FUD. A regular reboot should be sufficient and the simplest instruction to get X to autodetect what resolutions the new display can handle.

For NVIDIA users,

sudo apt-get install nvidia-settings

sudo nvidia-settings

Change resolution from there, and save the xorg.conf from within nvidia-settings to /etc/X11/xorg.conf

If you're talking about Big Picture Mode, edit the following file: /usr/bin/steamos-session and add the following lines to it:

xrandr -s 1280x1024

Change to fit your resolution.

[quote] #52 (comment) [/quote] Untrue. What should happen and what does happen are two different things.
Fear Uncertainity and Doubt hmm I fear steamos has total disregard for what monitor is actually conected to system. I am sure this is due to EDID information beng stored in steamos (instead of reading from monitor at boot time) which means connecting a second monitor (both simultaeneously or separately) will use old and irrelevant EDID information for the second monitor. I am uncertain this is unique to nvidia graphics. I doubt my last post is any cause for FUD.

Using VGA connection to 15" TFT monitor at install time means for me when connecting to 1080p monitor (VGA connection) it can only display 1024x768 max.
Following Toetje583's suggestion simply highlights no resolution avilable are any where near what second monitor is capable of. The display name is CRT0.

Why can't steamos update xorg and xrandr and other files as required due to hardware change!?

I believe this should be added. A resolution option should be an essential part of SteamOS

I have tried using the nvidia settings and the xrandr option in steamos-session to no avail...I still have a large black block at the top of BPM.

I have tried this: https://github.com/ValveSoftware/SteamOS/wiki/Custom-Resolutions-And-Refresh-Rates but it still doesn't work.
