without having changed any settings, and using the "info" button on the tv I can see the recalbox main menu displaying at 640x480, progressive, 60Hz, 4:3 aspect.

i can launch the game "Ura**s" on GBA. this game came preinstalled. it displays at 1920x1080, 30hZ, 1:9 aspect.

but now i have tried several games on different systems and they all work so far. all displaying with the same settings as mentioned above.

the only thing i have done is change the tv setting "auto aspect". it was annoying that every time the tv changed video, it tried to adjust the aspect ratio. so i finally disabled that. i tried games with that tv setting on and off and it worked consistently.

the global.videomode=CEA 5HDMI
global.ratio=auto

I really appreciate everyone trying to assist. but everything seems to be working fine and I have no idea why.

@mattmame
Initially the issue started for any game on any system under the same conditions for when it did function properly.
Since reinstalling I have only added NES and issue occurs.
Will attempt pre-installed games as soon as possible.

I am using raspberry pi3 b.

It happens for any added game. I have not attempted on any games pre-installed.

I will make the change in the settings. When I have a chance I will make a list of things I have tried.

When i start the console it loads to the emulation station just fine. when i load a game the screen goes black and appears to change resolutions but it never finishes and it stays black and the game never appears on screen. i can drop back out to the emulation station without issue.

if i press the info button on the tv remote i get info for the resolution and such. watching this i can see it change to a ton of different resolutions and frame rates. it even does weird settings like ##x0 or reverse. it finally settings and stops at 0x0. then i exit back to emulation station fine.

i reinstalled the OS and it still does this. it currently has all default settings. i did not have to change any settings for first use previously. it had started at after a decent period of non-use. i imagine i installed any updated before anything else.

i tested it on a second tv and the issue remained, and the emulation station displayed in a weird resolution.

any advice?
