LG C2 - Console Booting to Incorrect Resolution (640x480 / 1080p)

This is a new thread to replace the old one as I'm unable to edit the original title to remove 'solved'.



Issue:

• When powering on my Series X connected to a 42" LG C2, it will sometimes not display at the correct resolution, usually 640x480 although it sometimes displays at 1080p. When this happens, the console no longer detects any other resolutions as being available to select plus the console doesn't detect any enhanced features of the TV such as VRR, HDR, 4k etc. The issue seems to be random although unlisted changes within the Alpha Skip updates could be affecting frequency. Issue doesn't happen with PS5 console.

The only ways I've found to resolve the issue are to either;

• Wait a couple of minutes then reboot the console from holding the guide button (have to wait a couple of minutes or the console doesn't reboot correctly and displays at the same incorrect resolution)
• Force a full power off by holding the power button for several seconds
• Toggle the VRR options in the TVs Game Bar several times (doesn't always work)
• Toggle the HDMI Deep Colour setting in the TVs HDMI Settings menu (Doesn't always work
• Unplug the HDMI cable at both ends (Console and TV) then reconnect

• TV is on latest firmware 03.21.30 (21/12/22)
• Console at latest Alpha Skip Ahead

I try to report each occurrence via the Report a Problem app using tracing as advised in the 'Known Issues' part of each update release notes however due to how frustrating the issue can be sometimes, I'd just turn the console off instead.

For anyone who was having similar issues, the new option in the recent Alpha Skip Ahead build which allows you to set VRR to only enable when a game is started seems to have resolved the issue of the console booting to 640x480 on my LG C2.

EDIT: (02/10/22) - After 9 days of daily testing, I've had the issue of the console booting to 640x480 again. The only thing that changed since the VRR update and it seemingly being resolved is that over the last 2 days I've had a game running under quick resume which may or may not be related.

• After 1st reboot the issue resolved except that for some reason my 'XBOX Live Gold' tab was replaced with 'Exclusive Discounts' tab but was empty plus the Quick Resume tab was empty.
• After the 2nd reboot everything returned to normal but Quick Resume was still empty.

EDIT: (07/10/22) - I had the issue again on 03/10/22 and before rebooting the XBOX to fix it I found that when opening the Game menu on the C2 the settings were different to what I'd set, as if the TV was treating it as a different input source. I then disabled the HDMI forum VRR option (which I had originally disabled in favour of Freesync) and immediately the screen switched back to the correct settings and the XBOX was displaying correctly (4k, VRR , HDR, 120hz). Since doing this I haven't had the issue for 4 days and will update in a week or so's time if it happens again.

EDIT: (11/10/22) - Issue happened again. No changes made to TV or XBOX settings. Only way to resolve the issue is to reboot the console after wating a couple of minutes or to toggle VRR via the TVs settings. I'll get a mod to change the title of this thread to removed 'solved' and keep reporting the issue using Report a Problem until a proper fix is released.

EDIT: (22/12/22) - Currently testing to see if turning off the automatic console updates changes anything as I've noticed that when the console powers up to download updates, the TV shows the XBOX input as active.
