No HUD on Triple Head 2 Go

**SourceChild** · 21-12-2006, 01:03 AM

I absolutely know how this device works. That is why when I realized which video card I had, I realized the rez was too High for it.

If you remember, I was the one who was first mentioned using this device before it was released. I've used them plenty of times for other things but only since you added the code for doing the screen ratios have I been using them with Catalyst. Incidentally, I also use them with the edge blending feature as well since many of my set designs are comprised of irregular stretched spandex.

The circumstances today were specific to setting up a machine with one of the TH2G loading the new build you just released.

I thought I might have discovered a bug in the new build when I dropped the rez to what was within the range of the video card and noticed the high processing overhead.

Here is the PDF attached.

thanks for the profile Todd.

its very complex working through things that can and do happen with third party hardware.

there are many many combinations of devices systems, hardware - and its not possible to provide any 'rules of thumb' when things dont work.

you probably havent discovered a 'bug' but a combination of things that doesnt work with a specific system setup. ( and there will be many of them ). just as there are also many combinations that do work.

So -its really really important that i get as many details as possible.

what you described happens on early and older systems when their display resolutions are not setup correctly. or two monitors are connected at different refresh rates - and other things like this.

todd.

one of your monitors is 1280x1024 at 60Hz?
the other 3072x768 at 75Hz?

you have installed some older ATI display drivers? I noticed you have something called ATI monitor running?

-----

running monitors at different refresh rates is almost always a problem - you need to find a resolution that works - or combination of resolutions and refresh rates that work.

also suggest you uninstall any ATI drivers or monitors.
As unless these are very recent - they are likely to be the source of bugs in graphics.
But they might not. There are too many combinations of things.

---

This isnt going to fix anything - but suggest also you install 10.4.8

I had a setup with triple heads on a G5. And besides a mouse I got no HUD and nothing at all when running fullscreen.

Finaly Ruediger send me a PDF with information on triplehead stating that the G5 is not supported with triple head...

Please find enclosed this PDF

not true - as i have a show - 'Keane" tour - running on a quad g5 with both triple and dual heads. i think rob has 4 or 6 outputs. I cant remember.

i also have a several g5's on other shows with these devices.
including 'waves' at the national theatre.

all the information from matrox has been inaccurate.
this pdf simply shows what matrox might have tested - not what works.

it depends on the graphics card - and it depends on the operating system.
there are no rules of thumb-
these devices also sometimes work at different resolutions on different machines.

if it works - it works - it if doesnt it doesnt.
you have to test it.
not every resolution is supported at every refresh rate - sometimes only 2400x800 works - sometimes only 1920x480 works.

which g5 do you have - and what resolution did you try?

did you make sure you set up the resolution using system preferences BEFORE running catalyst - ?
You setup up the screen resolution BEFORE running catalyst - and you need to check you get a desktop output.

We had a double 2G G5 with the ATI 9800.

We ran from display propertys both outputs on 3072 x 768 with triple heads.. I hardly got that working from the Apple. Starting up Catalyst then en entering full screen.. No output what so ever and NO HUD's...

I was running m92 you send me for this show...

Ruediger tested this simultane in Germany on a G5 as well with another build and got the same result.

The machine is on the road and will return to Arcus-warehouse tomorrow.
I will then sent/check the profile.

I got the same issues like Fons with a G5 Dual 2GHz with ATI X800XT and OS 10.4.8.

very very old machine - 9800 very old graphics card.
suggest you did something that was not supported by this card. or this machine.

you cannot just plug this in and expect it to work - you have to test it.
i would be very suprised if a 9800 in a dual 2.0Ghz g5 went above 1920x1200 at its maximum - on a single output - which means you are leaping into the dark.

You say it hardly worked in 'apple' - then you expect it to work in a graphics intensive app like catalyst on an old low-spec machine?
