advanced displays stuck at 1280x800px res

[gwalsh]

hi,

I have a 6 output setup using the Matrox c680 graphic card. The Card is set-up and hooked up to six 1920x1200 projectors.

In resolume, advanced output settings these displays are shown as 1280x800. Does anyone know how to change this?

The graphics card is capable of pushing 4k through each output so 1920x1200 should be no problem. Im wondering is resolume max's out at 1280x800 for multiple displays?

Thanks

resolume only sees what windows reports, so you should set the projector resolutions in Windows first, then restart arena.
also check that the desktop scaling is set to 100%.

I had a similar problem a while back with some Blackmagic gear on Windows 8.1 and it turned out that Windows 8.1 was just reporting the wrong EDID information for some monitors / outputs. Take a look at this thread.

The way to test is to create a 1920x1200 composition and send the test card fullscreen to your displays.

....the 1 pixel lines are every 40 pixels vertically and horizontally.....so some of the 1 pixel lines should disappear if the resolution is being reduced and then blown up again.

Are you Using AMD Firepro Graphics Card?

@gwalsh - The Matrox C680 is one of the few cards Matrox makes that supports OpenGL but I don't believe there's been a lot of reports from the Resolume community that it works great so unfortunately you're still in mostly unchartered territory!

Also, you wrote in your post that:

The graphics card is capable of pushing 4k through each output so 1920x1200 should be no problem.

Keep in mind that the C680 still only has 2GB of system memory so six 4K outputs in a demanding environment is going to really tax the card.

Just make sure your Windows desktop scaling is set to 100%.
