We ran a number of diagnostic tests on the Asus PG221 to assess its image quality and performance. The pictures you see below are but a sampling of the tests built-into Lavalys' Everest Ultimate Edition. Everest Ultimate Edition in particular displays over 40 patterns to test a monitor's capabilities. Some are designed with CRTs in mind, but many of the patterns and screens are useful to gauge an LCD's ability to reproduce even colors across the entire panel to see how it handles a wide range of colors with a myriad of gradients.

To our eyes, the Asus PG221 made it through all of tests without any major issues. In all of the calibration screens and grid tests, the PG221 produced distinct gradients and sharp, perfectly straight grids in every section of the screen. In all of the text reproduction tests, the PG221 also did well, producing clear, sharp text regardless of the color combinations used.

Gradient fills, various gamma levels, and HSL color palettes were all reproduced very well. We also found that in the solid color tests, the PG221 produced even brightness from edge-to-edge. Some LCDs suffer from uneven distribution of their back-lighting, but this was not the case with our PG221 sample. We should also note, however, that this issue is barely perceptible during "real-world" use and is only a problem when a single, relatively dark color is being displayed across the entire surface of the panel.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
