Some game resolutions not supported by my monitor

Post by RetroBorg » Tue May 10, 2022 10:04 am

I've recently updated to ARpiCADE version 3.X and I am finding games that used to work on previous versions of ARpiCADE don't now due to a resolution issue according to the error screen that comes up on my monitor.

Most games work fine but games like Joust, Moon Patrol and Jungle King just come up with blank screens and some message on the monitor stating the monitor doesn't support that resolution. I can hear the games through the audio but no controls respond like escape or tab.

The monitor is a Dell P1914S orientated horizontally in my cocktail table, it's native resolution is 1280 x 1024 @ 60hz. It's aspect ration is 5:4.

My settings in the config.txt are hdmi_group=1 and hdmi_mode=1.

Do I need to play around with these settings to fix my problem or is the problem to do within Advance Mame and I need to change settings there?

Can someone point me in the right direction?

Thanks.

I have a feeling I should be using hdmi_group=2 and hdmi_mode=35.

So I've tried that and I've also included this in resSwitch.sh
if [ $hdmimode == hdmi_mode=1 ] || [ $hdmimode == hdmi_mode=2 ] || [ $hdmimode == hdmi_mode=3 ] || [ $hdmimode == hdmi_mode=4 ] || [ $hdmimode == hdmi_mode=16 ] || [ $hdmimode == hdmi_mode=35 ] || [ $2 == dryrun ]; then
But unfortunately that didn't work.

That's a headscratcher. It shouldn't be changing resolutions at all running in high res mode (hdmi_group=1 and hdmi_mode=1). Did you make sure the default low res settings were commented out? (that could possibly trip up the logic in the resSwitch - but I'm not sure that's what is happening)

The fact that no input works is also a bit confusing. I'll have to look into it for you tomorrow and see if I can figure anything out.

By default low res settings were commented out, are you referring to this part?
## Return to original boot resololution
## only works with 240p and 480i
# if [ $1 == defaultres ]; then
# echo $hdmitiming
# ##Return to 240p # resolution to
# if [ "$hdmitiming" == "hdmi_timings=1920 1 52 208 260 240 1 6 10 6 0 0 0 60 0 38400000 1" ]; then
# vcgencmd hdmi_timings 1920 1 52 208 260 240 1 6 10 6 0 0 0 60 0 38400000 1
# tvservice -e "CEA 65 HDMI" & sleep 3

I've worked out my issue. For some reason I had this:
hdmi_group=1
## Use only one mode at a time
# Boot and menus in 480i (rotated games in 480i, non rotated games in 240p/256p/288p)
hdmi_mode=6
# Boot and menus in 240p (all games in 240p/256p/288p)
#hdmi_mode=8
# Boot and menus in 480p (no res switching, just 480p)
hdmi_mode=1
So I had both hdmi_mode=6 and hdmi_mode=1 happening at the same time.

That's what I was trying to suggest was possibly it. Sorry I didn't make it clear which file I meant.

Glad you figured it out.
