Flat Screen Monitors for old SGI systems

[Snowman]

We would like to replace our old CRT for a flatrscreen TFT have tried all sorts of monitors none of which are able to display the graphics output.
Any suggestions?

LCD widescreen monitor
23"
WUXGA 230W5BS/00

This is the monitor we have running on our Tezro.. V12 graphics/DM 5

Which is also the same hardware on our Oct.2

I haven't tested it.... but I can't imagie that it wouldn't work.

How old are we talking?

Have you tried using the 15pin cable that came with the original CRT?

Dell 2001FPW (20", 1680x1050) certainly works, with an 13w3 to VESA adapter on an Octane MXE. I did have to roll my own video format file though, mail me if you need it. You could maybe do the same with the bigger 24" Dell.

On a Linux Flame I bet you could persuade a 30" 2k native screen to work... imagine that :-)

It would help to know which software version you are running on which platform, your display resolution, and whether you are mostly running at 60Hz (NTSC, 1080/60i), 50Hz (PAL, 1080/50i) or Film/24P.

We are running 2 "Old" systems here.
1) FIRE 3.6.1 on an ONYX 1 Infinate Reality
2) FLAME 6.6.1 on Octance 1

nice, we've got 3 flame 5.5.1's on onyx RE2's tucked away :) i think two of them still actually work too :)

Both your systems are likely to be running at 1280x1024 display resolution (/usr/gfx/gfxinfo will tell you), so that gives you a lot of flexibility, as there are tons of monitors which support that resolution.

But there's at least a couple of other things to watch out for. First, you need to think about sync on green vs separate sync. By default, SGIs output "sync on green", whereas a lot of LCD monitors want VGA-style separate h and v sync. You will need a 13W3 to VGA conversion cable which correctly brings out hsync and vsync to the VGA connector, and make sure the monitor doesn't get confused by the sync on green.

Also, since you list your location in the UK, you will need to make sure that the LCD monitor supports a 50Hz refresh rate, since a lot them tend to only want to work at 60Hz. And some LCD, while accepting non-60Hz signals, will show tearing when playing back video, as they internally resample the 50Hz signal to 60Hz, and do so in a non double-buffered way.

But in the end, given the low cost and easy availability of 1280x1024 LCD panels, you could just try different models until you find one that works well for you. Just make sure to keep on looking at your CRT broadcast monitor to make any kind of color decision.

Actual sync-on-green to H&V sync convertors/cables are pretty pricey, it's easier to just find a screen which supports sync-on-green. A lot do, some even if they make no mention of it in the specs - my Dell for example :)

And if anyone knows of any LCD which actually displays anything other than 60Hz without tearing, please PLEASE post here! It's SUCH a pain in the ass for PAL work!

[panisset]

Have you tried the 23" HP L2335 monitor? A great thing about it is that it syncs down to 48Hz vertical refresh, which is great for 24FPS work, and I believe it will display rates other than 60Hz without tearing. It also has a "one to one" pixel mode where you can feed it a 1920x1080 raster and it will display it in the middle of its 1920x1200 matrix without resizing. Unfortunately, it has been replaced by a newer model, the L2465, and although the specs for that also claim to support 48 to 85Hz, I haven't played with that one yet, so I can't comment on whether it tears or not at non-60Hz rates.

You are from a PAL place.

What you'll find is that almost any LCD which supports VGA and provided you have the converters appropriate to your SGI will work. However, while it will work to get the SGI GUI on, when you start smoke or flame, and switch to PAL, some monitors will not work.

Check that the monitor you select can actually do 50Hz at 1920x1200. Most monitors do down to 56 Hz. And people in NTSC lands don't realise this because if you're running smoke/flame in NTSC you'll never drive the monitor below 60 Hz.

The Philips that someone mentioned, does work with Octane/Tezro.
