We have a Qt 5 application running on our iMX6 Quad which we want to span multiple screens but we do not want to use multiple Qt windows.
For this I believe Qt needs to be provided with a single large framebuffer which we would then need to split up and write to the individual output buffers to achieve the extended display.
The two displays we’re using are the same size (10 inch 1280x800) and placed horizontally adjacent. One is driven by DISP0 (parallel LCD output) and the other is driven by LDB1 (LVDS output).
Has anyone else achieved this set-up without a window-manager and windowed application? We want to take advantage of the GPU’s hardware acceleration, is this possible using a single virtual framebuffer? Or should we be looking at a different solution?
