View Full Version : dualhead zoom
9th September 2002, 11:18 AM
I'm running all Vj programs on my dual P3 systems with Matrox G400 3D flex.
Matrox g400,g450&g550 are wery slow cards, but they have dualhead zoom option.
Is there any other faster graphic card with dualhead zoom (ati,nvidia)?

The zoom facilities provided by nVidia detonator drivers are inadequate for VJ use at the present time as far as I can see, there is no way to easily define what area of the screen to zoom in on :( Its a shame because the rest of their multi-display options are now quite good.
I think some software is being developed "Soft scan converter" which would do what you want with any multi-display card, but I dont know how its going (see developers forum)

My solution is Matrox Parhelia and i'll buy it.
Is there anybody with Ati Radeon 8500(hydravision) or Geforce 4(twinview) ?

Yes I have geforce 4 with twinview, as I already said its no good for what you want. The only zoom I could find followed the mouse cursor around, and even that seems missing from very latest driver!
I was excited by Parhelia but considering the cost and that the performance is not good compared to latest cards from others, I decided not to bother. Matrox do rule the 2D world though but they just cant quite get it together for 3D.

The point is dualhead zoom!

I thought the point was dualhead but with decent performance? If so the Parhelia is better but way overpriced for what it is (unless Ive been given wrong price info). Id get a nVidia card and a seperate scanconverter if it was me, how much can you get the Parhelia for now?
Only trying to help :(

I own matrox G450 video card and I have some tips to get better performance.
Please provide next information, and I will see what you can do :
motherboard ?, BIOS version ?
software and operating system ?

2elbows: Have you tried zooming in clone mode? I have passive zooming option in card menu disabled and I am very interested if in clone mode is it enabled.
I cant activate clone mode cause on my geforce is this possible only in combination VGA and Svideo out.

cubas what driver version are you using and which geforce card do you have?
I have used clone mode but the only zooming options I could find didnt seem to give me enough control, but as options are hidden all over the place I may have missed something.
I have used clone mode with the 2nd head on geforce ti4200 connected to monitor, and also with svhs & composite out to TV. Didnt notice any difference in options.
If you are using a driver verson before they released nView as their multi-display driver/utility, then I do not know as I only got my card recently so dont have much historical knowledge of nVidia multi-display functionality.

driver is 30.82_win9x, downloaded today from nvidia site, nview involved according to informations on site, nothing helped, clone mode still hasnt appeared in menu and magnifying glass zooming mode still stays grey
system windows 98
card is geforce4 460MX
i dont know why they (nvidia) should put there any button which couldnt work for anyone :confused:

Hey JJill !
whats up with the performance of g450 ?
what overclocking utility are you using ?
or is it about updating other system-hardware ?
i bought a g450 and would also like to know how to maximize video performance ! :nod:
Pleeeeaasse ! ;)

The problem with the Matrox cards is that the 3D side of it is really bad and out of date and so very slow compared to nvidia and ati cards of the last few years. 2D performance is still excellent.
THe Matrox Parhelia has better 3D but I still think its well behind the rivals, shame Matrox lost the plot on 3D IMHO and I dont see how they will get it back.
