No HUD on Triple Head 2 Go

[samsc]

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.

[samsc]

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.

not sure what you talking about . I know that some time the second head give problem during start up . i had many problems with it .

It seams that osX do not recognize it .

thats a really old g5.

if it works it works - if it doesnt it doesnt.

depends on the maximum resolution that the x800 will support - you have to start at lowest resolutions - try 640x480 times 2 which is 1280x480 or 1920x480.
you must not expect these devices to work at high-resolution of 1024x768x3. or even 800x600x3

x800 might only support up to 2048x1536 - and thats the maximum. triple head or no triple head.
the specs and the limits are real.

Mobility™ Radeon® X800 Series supports the latest high resolution and wide-screen notebook displays with a flexible and easy-to-use interface for multiple display settings. ATI’s new LCD Enhancement Engine (LCD-EE™) allows for support of the latest high resolution and wide-screen notebook displays such as WXGA (1920x1200) and QXGA (2048x1536).

you are dealing with real hardware and software limits.
Many older graphics cards only every worked - even at their maximum up to 1920x1200 - and even that was really pushing it. it really was.
the matrox triple and dual head - pushes things well over these limits.

you have to test every single combination you intend using.
and if you try to work at this resolution on two screens -?

Ruediger

yes and your graphics cards probably only work up to 2048x1536- if that?
and these are very old old machines.
you have to actually look at the specs of the machines...

there is no mystery here -

you are expecting these machines to do more than they are capable of....

this isnt a bug - in either hardware or software - you guys are pushing things over the limits....
