we are in a venue and we are facing a strange behaviour.
We noticed it because going to fullscreen felt like we were losing resolution. And indeed it does: we notice that when the renderer is at “expanded window” the resolution is perfect, whereas when we go to fullscreen, we lose definition.
Our setup is made of two video graphics card:
- a Nvidia GeForce RTX 3060 (the primary one, used for calculations);
- Nvidia Quadro P620 (the one we use to send images to 2 projectors);
The second video card has a different resolution respect the first one, it has a mosaic set on it for the 2 projector.
Using the “Overview windows and fullscreen” example patch we see that:
- when we are in “expanded window”, the windows size and the back buffer size have the same dimensions 3840x1129 - 3840x1129 . They both have correct dimensions, we see a clear and perfectly sharp image!
- when we sent the window to fullscreen with the
SetFullscreennode, while the window size stays the same (3840x1200), the back buffer show a different size which is the GeForce resolution (1920x1080 - for both the Quadro video card the resolution is 1920x1200 instead).
It looks like Gamma is not seeing the two Quadro at all.
How can we solve?
