The HP f2105 turned in a stellar performance on CNET Labs' DisplayMate-based tests, outscoring even top-notch LCDs such as the and the . Tested at its native resolution of 1,680x1,050, the f2105 performed especially well in some notoriously difficult areas: displaying grayscale and color gradients. The f2105 created smooth, gradual progressions of gray tones from dark black to bright white and back again without compression--the tendency to crowd sections of a gradient into one or both ends of the scale. The f2105's grayscale gradients were also free of red, green, or blue color tints--another common pitfall for flat-panel displays. Color gradations were also much smoother than the norm; the f2105 displayed changes in hue cleanly, without bright or dull spots. Text was reasonably sharp and easy to read but not exceptional. The f2105 showed no signs of streaking or ghosting during our gaming tests, and DVD playback showed some slight irregularities, but no more than on other LCDs.
HP offers a skimpy one-year limited parts-and-labor warranty; unfortunately, it does not sell an extended warranty for the f2105. Most other LCDs come with a three-year warranty and three years of tech support. HP's Web site offers customer support in the form of FAQs, problem-solving and installation tips, and driver and manual downloads.
