Title: TFT LCD turns of?
Post by: psyco on May 17, 2007, 08:52:03 PM

I got a very small hard drive with workbench 3.0 today and have put  monitors in /dev/monitors as it says do with my rgb to svga, my TFT LCD boots up ok.
Why will it not boot up when i put a game disc in?
All so if i open some PNG files or programs the monitor just turns of, this is all very annoying as you could  probbaly imagine :lol:
I must say i have not even played a game on the amiga since 1989  :lol:

Do you have a scandoubler/graphics card, or are you using a RGBI->VGA adapter and DblPAL/NTSC modes?

For the latter, that's quite normal.  Every program opening a custom screen drops back to default monitor settings (15kHz instead of 31kHz)

If you're using a scandoubler/graphics card, that's very strange.  Which model/brand are you using?

DblPAL works for workbench stuff only.

If you want something more game and demo friendly, head for a scandoubler or a graphics card.

I'm guessing a scandoubler is the cheapest of the two, and there are a couple on eBay at the moment:

Cheaper alternatives are a LCD TV or a VGA Box.

like others said, for games and other non OS-friendly apps, a scandoubler is required - note that a graphics card will NOT allow you to watch games on a vga screen, unless it has some sort of a pass through and internal sd (only some Zorro cards had those AFAIK)

The good news is that when in Workbench, you can use a little utility called ModePro (it has been more than 10 years since I used it, so don't ask me how) to "force" apps that open their own screens into a particular graphics mode - the downside is that it does not always work, but it should do in most cases (like watching pics etc)

a TFT-TV is among the best solutions - though I find that switching from vga to scart and back can be tiresome.
