Apologies if this is covering old ground but I couldn't see any
threads on it and a google search didn't show much either.
I would like to be able to have an RISC OS 3.1 machine and also a BBC
Micro all nicely set up to use regularly, but due to lack of space
this isn't remotely possible, but I was wondering the following would
work.
Can you connect an A3000 (or equivalent) to a LCD TV - I have a 22
inch LG TV and a LG 42inch TV, would these be capable of such a thing,
i've seen on Ebay Scart leads which connect your BBC to a new TV, and
Retro Software have a picutre of such a thing on their website.
If it was workable I could setup my A3000 (if it will work again) and
treat it like a Playstation, and then put it away when not using it,
same with a BBC and then I could get rid of my bulky A4401/ and
monitor set up.
Would this work? and would an A3010 be better than an A3000?
many thanks
cheers

SCART inputs on TVs tend to only work at TV frequencies. I'm not sure what
the A3000 does?
I have my RPC running into a TV via a VGA connector - many TVs have one of
these. The TV seems happy at any of the screen modes I've tried.

You do need to keep to TV compatible modes, although it is unlikely to

To damage possibly! If you mean might display higher resolutions on a
Scart input then I very much doubt that, I've certainly never heard of it.

Unfortunately many LCD TV's don't have VGA input.
I think Dave's comment re 'after a CMOS reset' relates to the fact that
quite a few LCD Monitors and TV's need *con. sync 0 on a RiscPC which is not
the default.
It's a bit naughty but I know some people put *con. sync 0
into an obey file in PreDesk!
I can't recall ever hearing of a monitor that needed *con. sync 1

Ah, well, I made sure this one had. My old 19" CRT Iyama was getting "a
bit long in the tooth" and I wanted something with HDMI for a RaPi as well
as something to use with a computer.
It is normally connected to my PC which can drive it at native resolution.
I have moved the "Taskbar" to be vertical down the RH side, run VA in
1280x1024 and still have space down the LH side to access the Icons on the
windows desktop, if I need to fire a Windows program up.
If there is something on the TV I want to watch, while my wife is watching
something else, it serves that purpose too. <g>

I think what is happening is that the actual monitor type is 4, but
the EDID is confusing the simple Acorn identification system and
making it think it is a multisync. (type 1)
Multisync will accept TV frequencies and different sync signals, which
an SVGA may not. (the different syncs may trigger energy star power
savers.)
The fixes are either chopping out the edid pin in the cable or
manually setting the correct values.

1920x1200 Dell went back on the Iyonix, and my son got the High res

yesterday, but think it's more a dodgy VIDC - Colourcard modes display
OK but RISCOS ones appear occasionally but more often "no signal".
Removing the CC left me with no display, but Ctrl-G beeps so the VIDC
cannot be entirely decrepit. No problem, as the CC modes are better
anyway, but it did put paid to seeing how far RISCiX would get on the
A5000. Judging by the lack of HD noise, nowhere, but it would have
been nice to see the "kernel panic" or whatever.
The relevance here is that (before diagnosing the VIDC problem) I did
consider hooking up the TV, which might have been more forgiving, but
baulked at the disruption to the study!

I thought I was having a similar problem with a CRT monitor and A5000
