[4.1] Dreamcast not displaying on TV

[kimmykaroo]

This is strange, I never had an issue like this before. For the record, I have
dc_boot.bin e10c53c2f8b90bab96ead2d368858623
dc_flash.bin 0a93f7940c455905bea6e392dfde92a4
in my BIOS folder.

I go to launch the game and then my TV seems to lose signal, and it says 'Not supported mode'. I am very confused on how to proceed.

By default Dreamcast is boot on 800x600 (DMT 9 HDMI). Maybe that your TV is not compatible with this TV mode.
Check on SSH using tvservice -m command (english wiki available on GitHub)
You can set the tv mode in recalbox.conf file.

@rockaddicted when I try tvservice -m in putty it just says 'option requires an argument'

maybe you meant tvservice -M ? I tried that and all it says is
[I] HDMI in HDMI mode
when I launch a Dreamcast game. Nothing else happens.

[rockaddicted]

You must specify your mode in this command DMT or CEA.
tvservice -m DMT

@rockaddicted Ah, yes, here's what I got.

[rockaddicted]

@kimmykaroo yep set the Dreamcast.videomod on DMT 4 HDMI
Exactly as the N64 is.
Don't force the global.videomode setting

@rockaddicted Thank you, it's working SO WELL now!
