15 kHz LCD!?
« on: January 06, 2004, 02:46:19 AM »
Seems like every multisync monitor question is answered with something like "get an LCD, most support 15kHz.".  Can someone point me in the correct direction.  I've searched NEC/Mitsubishi, Sony, and ViewSonic and haven't yet seen one that goes under 30!?  BTW, I'm looking for something in 17-20" range.
Time to move on.  Bye Amiga.org.  :(

Maybe the people you've talked to meant getting a LCD or plasma TV. Most of those have  composite RCA inputs for a regular TV signal. They'll be a little more expensive than a plain LCD monitor, though.

I remember seeing an LCD monitor with TV inputs. Look for that.

I've never seen an LCD that supports 15kHz RGB modes either.

Ones that have TV (composite video) input would certainly work, but I'm not sure how much the image quality would suffer using composite instead of RGB.

I use a 15" Mag monitor here on my A4000T, but runs through a PicassoIV which scandoubles all native 15kHz modes.
Beware of some monitors, like early Philips, which refuse to display scandoubled 15kHz modes, even though the input signal is within the monitor specifications.  I'd suggest you try before you buy.

Most "industrial" displays support 15 kHz. A few examples:

Siemens SCD 1815-I
Siemens SCD 1898-I
Products from Omni Vision

Search Google for [color=FF0000]15 kHz industrial lcd[/color].

Quite a few video monitors support analog RGB inputs, but they won't have the resolution computer displays do.

In either case, expect to pay $1000-$2000 (or more) for something semi-decent.

My 17" LCD monitor (AOC LM170A, I think) is running through my CV64 and internal scandoubler but although my scandoubled Amiga screens are viewable, I get a "Input Not Supported" floating around the screen in PAL modes.

This is because PAL uses 50Hz and the lowest my monitor goes is 55Hz. Bummer. However, if I switch to NTSC, everything is fine as the signal is now 60Hz.

Most, not all, of my WHDLoad games work in NTSC (Lotus series is great) albeit a little fast, but the picture is very nice.

If only I could frig around with the monitor to try and get it to accept 50Hz, or get my Amiga to up the PAL from 50Hz to 55Hz... Is this even possible?

Ok, that explains it.  Yes, I know I can go composite in, but the quality is so bad it makes the system practicly unusable.  

As for an industrial monitor, I think it'd be more cost effective to just get SD/FF for all of my computers and use a normal consumer LCD.

Most LCD TVs have component video (Y-Cr-Cb) input.  Why not rig an Amiga(RGB)->Y-Cr-Cb?  I've seen companies selling SCART(RGB)->Y-Cr-Cb conversion boxes...  Wouldn't this unit work with an Amiga->SCART cable?  

Would certainly be better quality than composite.

I have an 18.1" Iiyama TFT monitor which has 4 inputs: DVI (digital video interface), SVGA, S-Video and Composite.  I have connected the RGB out of my A4000 to it and it works, but for some reason some of the colours are slightly offset - may just be my monitor, though. Nonetheless, it's quite useable, and actually has the effect of a Flicker Fixer - I can use PAL Interlace completely smoothly on it. I think the model number is AS4636D or something like that.

Be warned, though - it was quite expensive.... very nice though!
