Blank VT-Vision

[shengiti]

I have what might be a simple problem, when I first received VT4 I installed it on dual core HP Workstation with Nvidia graphic card, everything worked fine, then we moved all hardware and software to an IBM that has Wildcat 4 7110 graphic card which we think has something to do with the VT-Vision not showing anything it comes up blank it wont display anything regardless where the source video is and regardless what button is pressed for it to output the video. Luckily we have some monitors that we hock up and use as program and preview so this problem is not stopping our work however it is something we would like to fix. If anyone of you ran into similar problem please write what could be the solution.

People have had problems before when they've used a card other than nvidia or (more recently) ATI. 3DLabs cards may be the absolute best or near to it, but they may not have the breadth of support for the native Windows video subsystem that VT needs.

It may well be that the wildcat has little or no support for the extended modes of DirectX. As I understand it, the wildcat is superb at OpenGL, but although LW laps that up, VT in general terms isn't really that interested! DirectX may be lacking, but I don't know first hand.

Please try a cheaper (sub $500) and proven display adapter card in that same IBM machine. The other consideration is that the Intellistation may be using the ex-broadcom serverworks chipset. This doesn't handle non-enterprise applications so well (for example the PCI implementation isn't as thorough as Intels design spec requires). So it may be less than adequate for this task as an optimum workstation. Any more info on the HP and IBM model numbers could be useful if possible please?

(Also - as the HP worked, did something happen to it that made you decide to not continue further with it?)

Fundamentally NewTek support most nvidia graphics cards and a rising number of ATI cards. 3DLabs cards may be inappropriate. Generally speaking you don't need even the latest family of nvidia of ATI cards as sometimes their immaturity works against them (hardware usually comes out and then the software catches up with it).

As you are working from a cabling perspective (in and out of the card) - you may not be far away from a working system even though I said what I said above. Have you tried the latest 3dlabs generic drivers?

Hi shengiti, The Wildcat 7110 will not play nicely with the VT. I was a 3DLabs dealer and we had lots of problems trying to use them for a VT type application. The 7110 is great for Open GL Architectural drawings and modeling but does have lots of problems with the way VT handles graphics. Get a 256mb nVidia card as was suggested and you will be fine. The 7110 stopped production about a year ago and 3DLabs is no longer selling high end video cards !!
