I dunno if it's relevant or not, but my go-to LCD for retro stuff is the
Dell 2007FP-
There was a panel lottery, some are TN, some IPS. Both are solid.
They are 4:3, 1600x1200 native.
They have DVI, VGA, Composite and S-Video inputs, and very stellar scalers.
They sync to SoG, and have no trouble with oddball resolutions like
1152x8-whatever.
My SGI stuff can drive it at native resolution. As an added bonus, you can
disable scaling if you want black bars and native resolution.
These are readily available for ~$35, and I have at least 6.

I have been keeping my eye out for older panels.
I have some 12"
4:3 and a few 17" 4:3 and I think one 19" 4:3. Never run across
anything larger. I don't think there were too many 4:3 LCD
televisions sold larger than 19"... some, perhaps, but not many. The
world switched to 16:9 about the time prices started falling on > 19"
panels.
I have a couple of arcade cabinets I'd love to switch to LCD. No
luck yet except with a 16:9 that would fill the cabinet space but
give me a black bars and a smaller playfield size than the CRT.
I use a NEC 21.3" 4:3 monitor--they can be had for cheap.
NEC sells a few refurb very inexpensive 4:3 19" monitors that accept SOG:

Will those sync with an Agilent 16700 at 1600x1200 at 75Hz? I've only found
one LCD display so far that will.

Glen asks:

> I've only found one LCD display so far that will.
I don't think I have the extended VRAM option in my Agilent to verify this,
but I'll double check.
I would assume they will take it, they're extremely well behaved and I
think I have gotten it to do 1600x1200x75 via an Indigo2(?). Great quality
analog handling on the VGA input.
The only thing I suspect that they don't like (but have not tried) is 15khz
via the VGA input- easily fixed by using a scandoubler (or composite /
S-video).
I've encountered nothing that hasn't worked on the 2007FP, but *has* worked
on another model LCD.
Glen: You are welcome to borrow one and give it a go whenever we hack on
the CDU PALs.
....
I'll also note another much sillier reason I like the 2007FP beyond
superb scaling quality, sync flexibility and overall image / panel quality:
The industrial design is minimal, angular, VESA-mountable, and inoffensive.
It fits well with decidedly retro surroundings- no giant bezel,
loud curves, or weird chassis colors to distract the eye; it fades into the
background nicely, which helps the experience and suspension of reality, if
that's something you're into. (Late night retro-sessions FTW)
They seem to be quite common right now as they're of the magic age
where offices have started to upgrade them to bigger, wider LCDs. I'm sure
that won't last so I'm hoarding them when they pop up at the ecycle, etc.

Seems to indicate that the Rainbow is a 15khz sync signal, more akin to
normal interlaced video- which I called out in my other post as being the
one type of signal that doesn't always work for these displays.
You may find success using a GBS-8220 scan-doubler, (ebay, c. $28
USD), perhaps with a sync-strainer circuit to feed the SoG signal to the
Scan Doubler as composite sync, if it doesn't work directly with the 2007FP.
Curious to hear what you figure out.

The Rainbow outputs a normal RS170-like composite video signal with the
same timings (so 15-odd kHz horizontal, 60Hz vertical). There is a setup
option for 50Hz vertical I think, if so it's going to be close to European
analogue TV rates.
This composite signal is the monochrome output. If you have a colour
video board, it is used as the green signal (which is thus SoG) and there
are separate red and blue signals. Obviously all at the same rate.

Another Dell that people mention is the Ultrasharp 2001FP. Apparently you
want one that was made before June 2005, because then it would be sure to
do 15kHz; some models going up to September 2005 apparently also had
support, but it's not guaranteed.
Do either the 2001 or 2007 support *digital* RGB/CGA out of the box?

Yes. It's TTL level. Since posing my question, I've gotten a tiny bit more
educated:
1. Some sites talk about e.g. arcade graphics as being "analog CGA" -- I
was acquainted with these being called "analog RGB" but never saw
"analog"
and "CGA" together before.
2. There are computers knocking about with actual digital RGB signals, like
the BBC Micro B (IIRC). What I forgot to make explicit in my question was
that I was asking about RGBI (+intensity), which AIUI is the same as CGA.
Now, I'm confused about point 1: did actual PCs with CGA have both digital
(TTL) and analog signaling?

I susepct it means that it's 3 analogue signals (one for each colour) at the
CGA (== US TV, RS170) scan rates. As opposed, say, to VGA which is 3
analogue signals with a rather higher horizontal scan rate.
2. There are computers knocking about with actual
digital RGB signals, like
the BBC Micro B (IIRC). What I forgot to make explicit in my question was
Yes, it dodes. The BBC micro has 3 TTL signals on the RGB connector. A
total of 8 possible colours.
that I was asking about RGBI (+intensity), which AIUI

Normally yes. I don't see any reason why RGBI signals could not be used
at a different scan rate, but AFAIK no machine ever did.
Now, I'm confused about point 1: did actual PCs
with CGA have both digital
(TTL) and analog signaling?
Not really. The original CGA card, and most clones, have a composite video
output too with NTSC-encoded colour, but that is not what you are asking
about.

Firstly, CGA is RGBI (digital RGB, with R, G, B and I for Intensity. But
there is a small difference in color 6
https://en.wikipedia.org/wiki/Color_Graphics_Adapter (see "Color Pallete")
- Arcade graphics are analog RGB in TV resolution (480i, 15.750KHz
horizontal, 60Hz vertical)
- CGA is **never** analog.
- Lots of old computers use RGBI (digital RGB). From my head: BBC mod. B,
Sinclair Spectrum +2/+3, Commodore 128, Amiga (yes, it outputs digital AND
analog RGB)
- There is no such thing as a CGA board with analog outputs.

New subject: When is Composite Video not composite video (was: Best LCDs for retrocomputing)
Hi folks,
So, my 'new' monitor arrives today, beautifully packed and I wasted no time
in testing all ports; should've brought home the monitor tester I have at
work since it can generate Weird Frequencies, in fact I'll take the screen
in tomorrow and hook it up.
Anyhoo, all good apart from s-video which I can't test without something
that outputs s-video. I know the Commodore 64 does but I haven't made up a
cable for that yet, another thing on the TUIT list. Composite tested
courtesy of an original Playstation and Raspberry Pi.
Then I remembered that I've composite modded a Sinclair Spectrum and a ZX81
and I get no picture at all with those, like the signal is too weak for the
monitor to pick up. Said pair of machines work fine on my 2008-era LCD TV
though so does anyone know what the difference might be?
Just because I could I hooked the Spectrum up to an Apple ][ Monitor and
that works fine - http://binarydinosaurs.co.uk/IMG_8839.JPG
Are there variations to the PAL Composite standard?

I think that the problem is probably that the Spectrum and ZX81 didn't
actually comply with the standard so much as use it as a general guideline.
Analogue monitors could cope, but many LCDs cant.

FWIW, the port I have tested a lot and can vouch for is the RGB / VGA.
Haven't done much with the composite.
But... my Sinclair QL with composite mod (NTSC) seems to work, and I
thought it used the same chips?

Any idea if they support arcade-type frequencies and inputs (i.e. TV rates

See prior references in the thread to 15khz input for "Arcade frequencies".
I have not tested it, some reports appear to indicate that it works.

Thanks... I'll prod my local recycler I think and let him know that I'm on
the look out for Dell displays, maybe he'll just happen to have one of the
right kind come in.
it would be the sync signal that I'd be concerned about, I know I've found
screens before which will handle the ~ 15KHz rate OK, but they still expect
separate H/V sync lines rather than composite (and splitting syncs seems to
be a bit more involved than combining them - well, trivial with the right
IC, but I mean using parts that might just happen to be kicking around in
my electronics stash :-)

My SGI stuff can drive it at native resolution. As an added bonus, you can
disable scaling if you want black bars and native resolution.
These are readily available for ~$35, and I have at least 6.
Hi Ian (and list),
Quick question, have you ever used a plain ol' composite input on yours?
Turns out my problem isn't just my problem, people have been having the same
issue since the screens were new - composite input just doesn't work unless
it's a very specific set of circumstances. That or there's a particular
setup required that isn't documented anywhere...
So far I've tried:
Spectrum (composite)
ZX81 (composite)
Raspberry Pi B
Apple ][GS
Amiga 1200
Amiga CD32 (this one *nearly* works, I get the splash screen)
Playstation 1 (ditto)
EACA VideoGenie
Have you got any of those kicking around you could plug in and test for me?
Cheers,

I mostly use the display for its fantastic handling and scaling of RGB
formats via the VGA connector.
I collect mostly old workstation class hardware and I care a lot about
image quality.
I'm not much of a microcomputer collector, and have used the composite
input very, very sparingly.
However, I have had enough issues in the past with the composite video
"standard" on various non-analog CRT display devices that I keep a timebase
corrector nearby and readily available. I find this a "must" for anyone
relying on composite stuff in this day and age.
I can try a IIgs- the only things I've tried over composite, I listed in
the other post.
Cheers,
- Ian

I will do some tests of the composite input this weekend with and without
TBC and see what I find.
I'll have to do a bit of digging for composite devices but I should have a
few.
