In addition to working with the PW191 alongside Dell's 2405FPW, we ran a number of diagnostic tests on the Asus panel to assess its image quality. The pictures you see below are but a sampling of the tests built-into NVIDIA's Rel. 90 Forceware drivers and Lavalys' Everest Ultimate Edition 2006. Everest Ultimate Edition in particular displays over 40 patterns to test a monitor's capabilities.

Calibration Screens

Grid Tests

Gradient Fills and Text

To our eyes, the Asus PW191 made it through all of tests without any major issues. In all of the calibration screens and grid tests, the PW191 produced distinct gradients and sharp, perfectly straight grids in every section of the screen. In all of the text reproduction tests, the PW191 also did well, producing clear, sharp text regardless of the color combinations used.

If there was one area where the PW191 faltered a bit, it was in the solid color tests. Gradient fills and HSL color palettes were all reproduced very well, but in the solid color tests, the lower corners of the screen were just slightly darker than the rest. This is a common problem with today's LCD monitors, however, due to uneven distribution of their back-lighting. We should also note that this issue is barely perceptible during "real-world" use.

Marco Chiappetta

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
