Multi-sync LCD/TFT monitor on Amiga?

[wa9yoz]

Greetings all!
Got dumb question: Would you still need to use a "Flicker-fixer" on a "Multi-sync LCD/TFT monitor" like for example the View Sonic #VA-1703w with your Amiga?
Specs:
Vertical refresh rate: 55 - 75 Hz.
Horiz.freq.: 30 - 82 Hz.
Anyone have any experience with those type, how about sharing the info?...Tony.
Thanks A-Org!

I think you will need a scan-doubler if you want to use that monitor with an Amiga. Vertical 55-75 Hz will not show PAL at all as that requires 50Hz, but will show NTSC at 60Hz.

Horizontal 30-82 KHz is indeed "multisync" but does not go down far enough to 15.60 KHz (PAL) or 15.72 KHz (NTSC). So either of these will need to be scan-doubled. PAL/NTSC interlaced modes are still at 15.60/15.72 KHz. Doubled screenmodes are also (mostly) not above the 30 KHz minimum of that monitor.

It's a VGA compatible display.

@meega

Are "Flicker-fixer" and "Scan-doubler" one and the same?


And in another thread it seems that LCD monitors capable of 15KHz are available.

No. A scan-doubler does exactly what it says - it doubles the scan rate - but it does not of itself remove the flicker of an interlaced display.

A flicker-fixer is also known as a de-interlacer. VGA monitors are quite capable of showing interlaced screens (with the accompanying flickering), but they need 30+ KHz.

15 KHz LCD displays are indeed available, they're called televisions.
