bezel correction

[lin]

Hi,

In Arena doing video wall with 4 monitors in 2x2 arrangement, how do you do bezel correction?

Do you have to manual adjust each slice?

What is best way to do bezel correction?

[Empyfree]

Maths and manual slice adjustments. Easy enough if you can get to the screens with a tape measure!

Are you doing the adjustment on the input slice or on the output transform slice?

Do you need spacing gaps between slices?

Do you need spacing gaps between slices?

If you have the displays on individual outputs you could adjust either input or output slices.
If you drive the displays with an FX4 or matrox triple heads for example, you'd need to adjust the input slices, as you wouldn't be able to make the output slices larger without overlapping.

If you'd have TV-s or signage displays, they might overscan, they also might overscan asymmetrical, so adjusting both input and output slices might be necessary.

Yes, using multi-display splitter boxes (like datapath, matrox)

OK, if doing this on the input slice, don't I need to have the slices spaced apart by bezel width of pixels?

How do keep the bezel width spacing distance on multiple slices (6-16)?

Also if for example 8 slices adjacent to each other (at least one side butts another display) but all displays are at 30 degree or other rotations (not simple horizontal vertical)?

Hey,check out this manual :

I have not tried it personally.But in my opinion this is what you need.

Thanks for the suggestion Topaazy but in this case we can not use. We have used Nvidia cards alot and have used the Nvidia bezel correction dialog before.

We need to do bezel correction within Resolume.

I understand how to calculate pixels for bezel thickness.

What I need help with is easy ways to get multiple slices to be spaced x pixels apart from other slices.
For example the border/sides of every slice must be 80 pixels from all adjacent slices.

There are many slices or slices are at odd angles (not landscape/portrait).
I think this also may apply to a video mapping projector based design.
Many rectangular shaped slices where each slice is rotated 45 degree but side of each slice must be 80 pixels from adjacent slices.
