A long time ago, I had a 5170 along with a 5154 and the IBM EGA to go with it. I'm curious now, I've got my hands on another 5170, but were there any VGA monitors that looked like the 515x displays?

That would've been cool, but I've never seen or heard of any.
IBM VGA displays arrived with the PS/2.

I was thinking/hoping maybe Princeton Graphics might have done a VGA, they did displays that looked like IBM's 515x's.

Oh right, that's more likely since a company making their first VGA display might be tempted to use the EGA casing from a previous model.
TVM displays also look like the 515x series but I've only seen CGA and EGA so far.

I did some light research into this myself, and the only things I could find where the PS/2 style VGA monitors, none that looked like the 515x monitors. So I am torn myself about what to do for my 5162 and 5170, keep the aesthetic or go with a slightly out of the aesthetic monitor with more colors and resolutions. I am thinking the 5162 may end up with a 5154 and the 5170 may have to go VGA.

To anyone that has done research into this: What was the first VGA monitor? I see/read conflicting reports (http://www.vcfed.org/forum/showthread.php?18517-First-IBM-VGA-Monitor) that it was either the 8514 or the 8513.

My interest in knowing this is that I need to pair a VGA monitor with an XT-286 and am trying to figure out which one would be more appropriate. My XT-286 came from an IBM employee and has an IBM-branded 8-bit VGA card in it -- but the owner couldn't remember what monitor came with it.

The 8513 was likely first as it was the "standard" option for the PS/2 range.

Weird, looking back I might have actually had a 8514 monitor not knowing what it was. It looked like a bigger screened version of the 8513. The PS/2 Model 80 it came with didn't have a 8514/A in it though.

The Princeton Graphics SR-12 can do 690x480. Not sure if it is analog or digital or both. It's NEC Multisync era, so may be worth checking out.

Not exactly, but the 5175 PGA display can apparently be converted to VGA pretty easily (I think all you need is a 9 pin to 15 pin adapter)

If it had a grainy image, that was the 8512. The 8513 was 12" with 0.28 mm dot pitch, and the 8512 was 14" with 0.41 mm dot pitch. Both standard VGA monitors, 640x480 maximum.

I had one of those on my Olivetti 286 after the original screen died. It was horrible!

It was likely a 8512. That .41mm dot pitch was awful even in the late 80s!

That article was very timely too, I was just fiddling with my NEC Multisync II's focus control using a similar test pattern.

Not as bad as the Tandy VGM-225 with 0.52 mm dot pitch! The worst VGA monitor ever made.

I was always a fan of the free anti-aliasing though.

Haha! It took me a minute to figure out what you meant.

The Toshiba TIMM (1995) takes the crown at .58mm, but it does a great job of blending the stripped palette 640x200 mode video on the Apple IIgs.

http://www.retrocomputing.net/parts/ibm/monitors/5175/ has some pictures, although some are quite blurry. It looks just like an EGA monitor until you see the "Professional Graphics Display" badge.

Wow nice, i think that they are pretty rare...

They are very rare, almost as rare as the PGA cards themselves.
