Testing tool helps evaluate high-end displays
CNET Labs acquires the Kramer VM-2DVI to accurately and efficiently test 30-inch displays
A couple months back I attempted to test two 30-inch displays--the
So I delayed the testing and the review for a few weeks. In the meantime I got in touch with a colleague at DisplayMate, Ray Soneira. He put me in contact with a company called Kramer. Kramer manufactures a number of distribution amplifiers including the Kramer VM-2DVI. This particular DA is Dual Link compatible and supports each 30-inch display's 2560x1600 resolution. So now I could test both 30-inch displays simultaneously at their native resolutions in DisplayMate and in our current games test, World of Warcraft. However whenever I attempted to run either our Kill Bill Vol. 1 DVD or our Swordfish BD on both displays at the same time, the DRM gods reared their ugly heads and denied me salvation. So when testing how each display handles disc-based movies, I was forced to evaluate each display one at a time. The Kramer VM-2DVI is not advanced enough to circumvent DRM tomfoolery, unfortunately. That said, we're still very pleased that the VM-2DVI allowed us to do the bulk of our testing as fairly and accurately as possible.
The issue of not being able to view certain disc-based movies simultaneously on two or more displays may not be an issue for long, as CNET Labs is considering moving away from using movies--and even games-- to evaluate the quality of a display. The reason being that video images generally move too quickly to do a picture quality comparison, whereas static images such as high-quality photos can be studied as long as necessary in order to examine their quality. No decision has been made as yet, though, but look for more on this in a future Inside CNET Labs post.
