I'm using RISC OS on a collection of rPis with assorted monitors. Some of the monitors use composite video.
When the standard distro starts, RISC OS comes up in 1920x1080. On the
7 inch TV, this results in buttons appri=oximately 0.3 mm high, which are quite hard to hit. Changing the screen mode is, at best, fiddly.Am I right in assuming that the composite video doesn't support EDID, or anything like it, so the initial resolution (during boot) is set solely by config.txt?
Am I right in assuming that the Auto MDF somehow picks up this information to set the RO screen?
If I force a low res mode in config.txt, can I then use a hi-res mode in RISC OS?
Can I set up config.txt so it uses EDID if available, and if not, defaults to low res?
Since the monitors I'm using vary from 19 inch to 7 inch, some VGA via HDMI adapeters, some composite, and I'd like to have an SD card image I can clone to any of them, the screen res issue is complicating things.
Any suggestions as to how I address this?
