So finally it’s here. We were pestering BenQ to send us this piece for a couple of weeks now - they’ve obliged, and sent in the highly coveted LED backlit monitor of theirs, a rarer and now new entrant to the LCD monitor market in India. There are other brands with such models, but today is BenQ’s day so we will show our spotlight (also made of LEDs) on them today, more specifically, their V2200 LED Monitor as they call it. It’s an LCD monitor with an LED backlight. Let’s turn it on right away.
Design and features
Alright, so the pictures say it all. This model is a pure milky white colored piece, with the finish being a matte surface. It’s very… Apple looking, with rounded edges and solid joints. The front view is asymmetrical, with the stalk for the stand juxtaposed to the screen just a little off center, to the right. These are all aesthetic plus points. But then, BenQ has gone ahead and done something stupid, whatever their original intention was.
There is a green colored circular piece of work sitting on the left side of the stand, it’s got blunt spokes of different lengths, and looks like a pad used in some cheap massaging gadget. I think it signifies green eco friendly grass or something— the designers surely were smoking some of it to give the go ahead for that. Not that it can actually deter the performance of the screen, so let’s leave the green thing alone.
The power on button is a small round flush paneled one with a cute little green LED right at its epicenter. The control buttons are on the right side panel, each of them being rectangular push buttons, albeit not too high tech looking. But all the buttons have a good tactile feel. The screen can tilt up and down about 10 degrees, but no swivel. The package comes with a VGA cable.
Connector-wise we have a single HDMI in, and a VGA in, no DVI. This too is odd, and surely is a cost cutting tactic. This model has a screen size of 21.5 inches, and a native resolution of 1920 x 1080. The slim bezel makes it look wider, actually, but it’s a true 16:9 aspect ratio. The LCD panel itself is assumed to be a TN panel. Brightness is rated at 250 Cd/m2 but one must remember that the backlight is an LED backlight. Response time is 5 ms. The contrast is rated at 1000:1, and the dynamic contrast is rated at 5,000,000:1. Also, this model by virtue of its technology, is more efficient than regular CCFL ones, with a rating of upto 36% energy savings.

Performance
The first thing one must know, is that an LED will take some time to get to its brightest rating. Another thing about LEDs, that is different from CCFL backlight: CCFLs can diffuse very well, to show different level of brightness. But LEDs use Pulse Width Modulation to show that they are dimming in brightness, meaning that the light actually is emitting at its full brightness whenever on, and to actually show different levels of brightness, the light is put on and off at fast flicker rates. So if you need a darker image, it is put off for longer periods. But of course the human eye cannot see this happen, it’s all above the fusion threshold of the human eye.
