Thx for your answer
one thing you could try: instead of specifying the native 480 for the videos height specify 240. i remember that some capture-drivers then simply left out one field. while this reduces your resolution it could do as a test.
when running in 320240 the video in not interlaced but quality is not good enough for my purpose. Running 720240 seems not to change anything.
otherwise i didn’t really get the difference between those two laptops. i guess both have one displayport output?!
W510 has NV Quadro 880m, non optimus graphic card. It can only run 2 screen at a time
W520 has NV Quadro 1000m, optimus graphic card and can run 4 simultaneous screens (i only need 3)
how do you connect the two external monitors?
First one is connected to the built in VGA port, second one on Display port regardless with VGA/HDMI adapter cable.
is this on win7 or 8? or 8.1?
Windows 7 64bits
do you go fullscreen with one renderer over both outputs? or do you need 2 renderers?
There are 2 renderers, one for each external screen. The go fullscreen all along the show. This part of the patch works perfectly and smoothly, no frames dropped.
if on the better pc you try with only one output (as you can to with on the other pc) does it then also work?
Cheater always fail ont this PC whatever the number of screen connected. under 720480 it don’t crash but don’t deinterlace, also the selection of deinterlacing method is messed up in the videotexture node. I tried with a minimal patch to debug and it’s the same, only running with the laptop screen. VVVV crash as soon as i setup video in on 720480. I also tried with 3 different USB grabbers, same for all. All of them work correctly on the W510 with cheater node attached and are deinterlaced.
Thx for your help
