Tested at its recommended resolution of 1,600x1,200, the ViewSonic G220f performed fairly well on CNET Labs' DisplayMate-based tests, but it wasn't up to the standards of a monitor for graphics professionals. Text was sharp and letters were distinct, though not as dark black as we would have liked. The G220f showed acceptable screen geometry; except for some slight pinching of the corners, vertical and horizontal lines could be squared to the bezel with minimal distortion.
Grayscales on the G220f were not spectacular. The screen displayed a good range of shades, but we could see tints in pink and green. Black didn't appear as fully saturated as it should have; likewise, pure whites looked dingy. The G220f's colors looked good with photographs and graphics from the Internet, but our color-test screens showed slight compression, or lack of differentiation, at the dark end of the scale. Gaming backgrounds on the G220f were full of vibrant colors and fine details. DVD playback was also good, with sharp details, accurate flesh tones, and minimal noise.
The G220f comes with a tiny printed quick-start guide and a CD-ROM with a much more in-depth user guide. ViewSonic's Web site offers FAQs and links for buying extended warranties, downloading drivers and utilities, and calibrating your monitor online. It also offers e-mail support. The ViewSonic G220f comes with an industry-standard three-year warranty, during which you get 24/7 tech support via e-mail and a toll-free phone number.
