Hi,
I have my RetroPie system working well except for one issue.
I have a short HDMI extension cable (I use this because I have the Raspberry Pi mounted inside a case).
Whenever I’m using the cable, and I quit an emulator, the screen goes blank. The RPi is still alive, as I can SSH to it.
If I remove the extension cable, and plug in a regular cable only, there is no problem.
I have done some tests with sudo ‘/opt/vc/bin/tvservice -s’, and I have found that the resolution does not change back to 1280×720 when the emulator exits. It stays at 640×480.
If I use the regular cable, I get this:
On boot – state 0x12001a [HDMI CEA (4) RGB lim 16:9], 1280×720 @ 60Hz, progressive
During game – state 0x12001a [HDMI CEA (1) RGB full 4:3], 640×480 @ 60Hz, progressive
After game exits – state 0x12001a [HDMI CEA (4) RGB lim 16:9], 1280×720 @ 60Hz, progressive
If I use the extension, I get:
state 0x120016 [DVI CEA (4) RGB lim 16:9], 1280×720 @ 60Hz, progressive
state 0x12001a [HDMI CEA (1) RGB full 4:3], 640×480 @ 60Hz, progressive
state 0x120016 [DVI CEA (1) RGB lim 4:3], 640×480 @ 60Hz, progressive
I have tried various options in config.txt, but nothing I have found works. HDMI safe mode also gives me a blank screen.
Any Ideas?
