Hello

[stefcep2]

put vga-only and multisync, dblntsc and pal/ntsc drivers in devs/monitors and reboot.  (Use the composite out on your a1200 and any rubbish tv to see a PAL or NTSC screen).  open screen mode prefs up and select multisync and hit use and see if you get a screen up on the tft.

So if any TFT / LCD tv with a SCART in and VGA IN will work with any screen mode on AGA ?

The SCART IN on TFT / LCD TVs have flicker fixers built into them don't they, to step up the 15KHz signal....so that it will work on that display.

...so does that mean all amiga AGA screen modes will work if connected through the Video out on A1200 into SCART in on LCD / TFT TV? And just don't use the VGA input (as the A1200 output is only 15Khz....no good for these input right.

This is so confusing....why didn't they just have a VGA output on the A1200's?? :idea:  :madashell:  :crazy:  :pissed:

because all games were made to work on PAL or NTSC, not vga

I have a Viewsonic LCD monitor here that I'd love to use with my 1200, but despite their website telling me this: "Frequency fh:30~62kHz, fv:50~85Hz", I can't get anything to display on it at all. The monitor just reports a lack of sync, regardless of whether I use the double ntsc mode or the vga only mode. The annoying part is that the composite signal changes and of course doesn't get displayed on my TV because it's out of range! I think it's because the output of the Amiga is just a slightly longer wavelength than the 30kHz input the monitor needs, but I'm not really sure.

I think thats your problem... Amiga can only display the VGA modes at 60kHz...

Not comepletely sure though... would a couple of kHz really matter?  :-?

yeas acouple of khz DO matter, thats why you have the vga-only driver, to boost the signals,  NOTE: the vga-only driver on its own does nothing: you must have multisync or dblntsc in devs/monitors as well as vga-only

you're all getting mixed up here.

30~62kHz

this is the horizontal sync. 15 KHz for PAL/NTSC, 30 for DBL and Multiscan modes.

50~85Hz

this is the vertical sync. 50 Hz for PAL and 60 Hz for NTSC/Multiscan. I think although some monitors do claim they accept 50 Hz but in reality they don't. That's most probably the problem. My LCD says it accepts down to 60 Hz. But actually it also displays 50 Hz, though with a warning message which says out of range. So I'm kind of lucky.

Yep, so does my Samsung 510T TFT. Specs say it goes down to
57 Hz, but it will take 50 Hz, without a warning message.
Other people with a samsung lcd reported that too.

I'm new to the Amiga world, but wouldn't this work in place of a scan doubler? RGB to VGA Adapter  :-?

it would, but it would be composite quality on a VGA monitor.  Kinda a oxymoron!

I'm using something like that at the moment on my 1200 for games use, not too bad and will be even better when I can get S-Video out of my Miggy.
