We used Display Mate for Windows video edition to adjust each model according to instructions and patterns stipulated by the application. We looked at subjective image samples, movie clips and patterns to get a feel for the image quality and clarity. We also ran 3DMark to see how they looked in a fast paced graphically intensive environment.
Our test rig remained the same for all units -- an Acer Veriton 7800 with an Intel 830 (3.0Ghz) CPU, 160GB SATA HDD unit, 2GB RAM, and a NVIDIA 6800 video card with dual DVI outputs. In all the tests we used the DVI input on the monitors.
We also looked at the monitors for viewable screen size, base design, and level of adjustment (up/down, forward/backwards tilt, and left/right swivel) as well as whether or not they supported landscape/portrait rotation.
Ports are considered and internal speakers, USB, Kensington security lock ports, along with VESA mounting points are noted. Whether or not external "brick" type AC adaptors are used or whether IEC power sockets are available to power the monitors directly was also looked at.
Great monitor, clear graphics display.
Im running 2 computers in my room one running DVI and the other D-SUB, and i love the feature to be able to switch between the 2 displays!
