The integrated TV receiver seems to affect the image quality in PC mode. Interestingly, I have a much worse picture via DVI, HDMI as above. But the image via HDMI is nichtmit the normal PC monitor to vergeichen. The image is sharp and uneven partly oversaturated. Unfortunately, the manual tuning brings no real solution. The aspect ratio in itself is fine, games ran with liquid representation and without streaks. The TV operation is good. All in all a not necessarily optimal compromise between TV and computer monitor world.
