It's worth setting up screen gamma properly anyway, especially if you're
doing any graphics work.

Exactly what is the monitor? Is it calibrated correctly? This may help:

IIRC, the app itself isn't 32-bit, but all it does is put the sprite
file on the screen (in Resources.Sprites). It doesn't go up to
1600x1200, but it may help if you place it in the centre of the screen
and get the monitor to self-calibrate.
