BenQ V2220 claims 'world's slimmest' monitor title
BenQ is on the warpath today, updating its V series and crying from the mountaintops about unbeatable slimness and contrast ratios. We could care less about the supposedly class leading 10,000,000:1 dynamic contrast ratio, but the 15mm thinness on the flagship V2220 certainly intrigues. It's claimed as the thinnest 21.5-inch monitor around and its junior sibling, the 18.5-inch V920, shaves another millimeter of thickness off while claiming the same title for its size class. Naturally, they're supplemented by slightly bulkier 23- and 24-inch varieties (V2320 and V2420, respectively) for those who need the extra room, with H variants offering HDMI and headphone connection options. You can expect 1920 x 1080 (1366 x 768 on the V920) resolution, 250 nits of brightness, 5ms response time and a good 1,000:1 real contrast ratio across the board, with the Taiwan launch set for the next couple of months followed by global availability in June.
What's dynamic contrast anyways?
In the world of video quality there aren't many specification more important than the contrast ratio -- if you enjoy movies or TV shows with dark scenes. Unfortunately, this also happens to be one of the most worthless specifications because every manufacture measures it differently. One of the latest tricks manufactures did was to introduce Dynamic Contrast. So instead of measuring the difference between the whitest white and the blackest black displayed on the screen at the same time, they display white and black on the screen one at a time and then measure the difference. Obviously this is next to useless, because this almost never occurs during normal programming -- of course there are exceptions to this, like alpine skiing or ice hockey. But it is the detail in the shadows and the ultimate appearance of black that is appealing in most programming. In the end the only way to compare apple to apples when looking for a new TV is by going to a trusted reviewer who always measure contrast the same way.
