I can't manage to go to resolutions of 1900 so i believe something is not working right...
The internal display resolution depends on the display.
Not quite sure what Qosmio F750-xxx do you have exactly but from my knowledge the Qosmio F750 models equipped with an glassed free 3D display supports an 3D resolution of max 1366 x 768. The 2D can be set to 1920 x 1080.
According notebook specification native resolution for your display is 1366 x 768.
Your notebook has NVIDIA GeForce GT 540M graphic controller with Optimus Technology and max supported resolution is 2048x1536.
hmm so if i was using the nvidia I should be able to go as high as 2000 right?
The graphic chip supports different resolutions and the max resolution is 2048x1536.
But this does not mean that you can use this. If the display does not support such resolution, you will NOT be able to choose it.
Maybe you just need the NVidia driver in order to set your internal display to its maximum (native) supported resolution. This should alao help you with the 3D problems you've written about in your other thread. The 3D mode only works when using the NVidia driver while running exactly 1980x1080 resolution. Otherwise, the face tracking application won't even start.
