Video issue following temporary monitor change

Englischdude

Hi All,

I am experiencing an issue with the display for my pi. Ill explain in more detail, but first here my setup:

Rpi4 8Gb in Argon One Case
Cant find the version number retropie, was installed in October so I think 4.6
X-Box USB Gamepad Controller
Main Emulators used MAME2003, NES, SNES, Colcovision
Video using HDMI1 output to my Sony KD-43XD TV

The issue is as follows:
everything was running just fine. I have an old arcade bartop cab in the basement which I am giving to a friend. The cab has everything installed, MINI-PAC encoder, 17" hdmi monitor, speakers etc., so to check that everything is working I
temporarily installed my Pi in the cab. Once I had checked everything I removed the Pi from the cab and connected it back up to the TV. Now I have the issue that the game window is on the left hand side of the screen and not central. THis is the same regardless of which emulator I am using.

I have checked through the documentation and searched the forums but cant quite find a solution which fits my issue. It must be a universal setting somewhere which effects all emulators, I have searched through all the settings for both retropie and retroarch but can find nothing relating to game window position on the screen.

I have not changed any video settings when testing the cab, the only thing I had to change was the audio output from dhmi to 3.5 jack so I dont know how this video issue could have been caused.

I would very much appreciate any tips for troubleshooting this issue. I would hate to have to install everything from scratch again.

Many thanks in advance,
Martin

So it's only the game video that's not fullscreen, is EmulationStation working alright ?

My guess is you've set saved the resolution in one of the RetroArch's configuration files or - unlikely - in the Runcommand launch menu options for video resolution.
Did you use the RetroArch's 'Save Configuration' menu at some point, when configuring ?

Check the /opt/retropie/configs/all/retroarch.cfg file for any video resolution options or in /opt/retropie/configs/all/videomodes.cfg (where runcommand stores the video modes chosen during launch).

Dear Mitu,

thank you for your feedback. Yes, I did activate a setting in retroarch (before testing the CAB) which saves any changes upon exit. At that time, I wanted to transfer the D-Pad control to the left analogue joystick on the new xbox controller. Could this save on exit setting be the issue?

The Emulation Station display window is fine, full screen at correct resolution. It is only when I start a game that the game window is aligned with the left edge of the tv screen. Just so I know what to look for, what could b a typical setting in retroarch.cfg which causes this? Just seeing resolution number such as 1280x768 is not going to tell me much about the game window position on the screen.

Many thanks for your help.

You can look for video_windowed_position_x , video_windowed_position_y for the video position and remove them, similarly for video_fullscreen_x and video_fullscreen_y to remove the previous resolution.

My advice would to be to use the default configurations, which are pretty minimal and wouldn't cause issues with portability. Changing the input configuration can be done separately via core/game overrides from the RGUI or with the Configuration Editor.

Thank you Mitu,
i have removed the SD Card from the pi and put it into my linux mint laptop and just opened the retroarch.cfg from there. I have located these lines:

video_fullscreen_x = "0"
video_fullscreen_y = "0"

and

video_windowed_position_x = "0"
video_windowed_position_y = "0"

among of course many others. Please confirm I should completely delete these 4 quoted lines.

Many thanks and regards
Martin

These are the defaults, removing them won't help. Which file is this, specifically ?

thee first one you mentioned, namely:
/opt/retropie/configs/all/retroarch.cfg

RetroArch has a config hierarchy - explained here. You should check other systems' configurations for custom video options.

Thank you Mitu, but for me, a power-user at best, thats going to be like looking for the proverbial needle. Before I spend hours trying to troubleshoot this Ill just save my roms and do a fresh install.

Thanks anyway and kind regards
