Reply To: Pro – AV4 steamdeck no display? edid? hdcp? cec?

Tried again tonight with the following info:

• 0.77 firmware – when running steamdeck into av4, av4 shows “free run” and nothing under signal info for the most part (regardless of extra-av-out). Steamdeck is on latest firmware/sw, dock is latest firmware and can confirm all cables work going into tv, just not through ossc pro.
• can confirm extra-av-out can work for me, i fed through a megadrive and had it showing on both tv and crt at 240p – it even handled the res change in sonic 2.
• on the rare occasion i can get info, it shows up as 800p which is the default res of steamdeck – my guess is ossc pro can’t handle this resolution but it’s accepting it?
• on steamdeck desktop mode, it shows up as Ossc Pro as the display and manually setting output to 720p still shows black screen and no signal info.
• the settings seem to get stuck when using a combination of av4 and extra-av-out – sometimes changing things just won’t affect the output. I would have the output on the CRT stuck to the 480i test image (but still showing menu changes) and I can’t change the position/height/width under scaler. Changing between scaler, pure and adaptive does nothing at times – i would either need to change input or turn off/on the unit to see anything.

Does anyone have a 720p60 edid i can load in the ossc that would force the steamdeck to send that – it might be all i need?
