I changed system.es.videomode=auto -> system.es.videomode=CEA 4 HDMI (as you asked)
Started a N64 game then I quit the game. Screen resolution turned bad. And here is the archive ;

Another thing might help; I use hdmi to dvi cable. So monitor is in dvi mode.
@alpermis ok, try this fix by running SSH commands:
mount -o remount, rw / rm /usr/lib/python2.7/site-packages/configgen/utils/videoMode.pyc wget -O /usr/lib/python2.7/site-packages/configgen/utils/videoMode.py https://gitlab.com/recalbox/recalbox-configgen/raw/0769d875ca343ddffd19721e96595e92511470f2/configgen/utils/videoMode.py
No need to reboot, just start games from ES including N64
tell me if it fixed your problem
The same.

@alpermis ok, investigating
@alpermis new fix :
mount -o remount, rw / rm /usr/lib/python2.7/site-packages/configgen/utils/videoMode.pyc wget -O /usr/lib/python2.7/site-packages/configgen/utils/videoMode.py https://gitlab.com/recalbox/recalbox-configgen/raw/0bc27e90248812a62f80de94810434acbf7ac418/configgen/utils/videoMode.py
the rm could fail, not a problem
It seems fixed 
Thank you very much.
I noticed couple of other issues. Im gonna try to be sure about those and open other threds.
@alpermis great thank you for participating in the debugging
nickel chrome plus de probleme avec la n64 , merci
Wow thank you. This issue has been resolved. It originated in dreamcast and n64.
@rizzie happened with systems having a forced resolution
@substring said in 18.03.16 screen resolution problem.:
The log shows
[ 44.50] configgen/videoMode.py(isSupported:68): The resolution for 'CEA 4 HDMI' is not supported by your monitor [ 44.53] configgen/videoMode.py(autoMode:115): auto mode -> CEA 4 HDMI not supported, fallback to default@barto28 has the very same problem, but switching to auto mostly resolved the problem but for N64.
I just wonder where's the path of that log file please? I'd like to see what's going on, on my Recalbox. Thanks.
@tekkenism ~/logs/recalbox.log, you can also see it from the webmanager
Former dev - Please reply with @substring so that i am notified when you answer me
Ex dev - Merci de me répondre en utilisant @substring pour que je sois notifé

Perhaps I'll sound silly but I disabled Webmanager and that Media Player, for..ermm...saving a bit more RAM. Eh?
Anyway, I'll nano that log file from time to time. Recalbox is a stable thing, I really want to -contrinute- it to be rock-solid!
@tekkenism no need to nano, just view it through network share
