The monitor was supplied with different video resolutions to see the visual quality of the picture. I found that the refresh rate of the GS771 is the deciding factor in the quality of the picture between resolutions. Hence, I've focus mostly on refresh rates. Text looks sharp around the edges. Comfortable for the eyes.
Photographs looks good.
There is sufficient blending and contrast where required. Maximum of 110 Hz refresh rate is the rate I've tried, not actual physical limit. Refresh of 88 Hz still provide a comfortable rate for the eye, though clearly not as rock solid as 100Hz. Complex Wireframe lines in CorelDraw are clear and sharp. Simple graphics colors are vibrant.
