Mixed messages continue with Dell’s lineup. The ST2310 has the usual specs you expect from a 23” widescreen: 16x9 aspect ratio, 1920x1080 resolution, 250 cd/m2 brightness, 5 ms response, and a 50 000:1 dynamic contrast ratio. Dell bills this as an “energy efficient” model, and with a 30 W maximum draw (22.5 W typical), that would seem a fair description.
However, this is not an LED display—it’s CCFL. Dell also has it listed at $239.99. But ignore that. The last price we found online was $160, setting it close to the ST2320L (below). The ST2310 provides one port each for HDMI, DVI, and VGA, and there’s even an optional, clip-on “SoundBar” for better audio than what the integrated speakers can provide. But hold those power numbers in mind. This gets interesting.
Second verse, same as the first—only this time with LED backlighting. The ST2320L is a near-match for the ST2310, but the backlight change pumps the dynamic contrast up to 8 000 000:1. Interestingly, this LED variant sheds just over three pounds compared to its CCFL counterpart, even though there’s no change in screen size and the stands are fairly similar. Power draw remains almost identical at 30 W max and 24 W typical. Yeah, you read that right. Keep going...
Samsung SyncMaster BX2350
Of all the comparisons we saw in this roundup, Samsung was closest to hitting our expectations. The BX2350 is a 23” 1920x1080 widescreen with 250 cd/m2 brightness, two HDMI ports, one VGA, 2 ms GTG response, and Samsung’s usual bevy of menu options and features.
It’s a shame that we can’t take you inside all of the features Samsung packs in here, because our testing depended on normalizing the settings between all monitors, and that meant disabling every possible image and power optimization. Suffice it to say that we appreciate the thought Samsung puts into promoting its greener-than-most manufacturing practices and the ways in which it makes image optimization according to content type and environment very simple. Samsung reports a static contrast ratio of 1000:1 and doesn’t bother with dynamic numbers—kudos to Korea. The power spec lands at 26 W.
Samsung SyncMaster P2350
The P2350 is Samsung’s 23” CCFL display in this group. Again, we see the older tech toting a bit of extra blubber, weighing in at 11.24 pounds to the BX model’s 8.15 pounds. More interestingly, the P2350 sports a brightness of 300 cd/m2 to the BX’s typical 250 cd/m2. Samsung lacks a few “Magic” features on this design, but the notable spec is a 43 W maximum power draw, making it potentially the least power-efficient model under review here. Let’s move on and see if these backlights and their energy draws add up in the real world.
Our CCFL-based Viewsonic unit counterbalances the LED-backlit BenQ in this roundup. The 23.6-inch screen sports a slim bezel, fully adjustable stand, and only VGA and DVI output. Curiously, there’s no HDMI output on this display, although you do get a couple of 2 W speakers and a pair of USB 2.0 ports. Viewsonic specifies a typical power consumption of 45 W, placing it at the top of our environmentally unfriendly list. However, Viewsonic combats this with an Eco-mode, although product documentation gives no clue as to what this is or how it works, only that it’s accessible via the on-screen menus.
Viewsonic specs a 300 cd/m2 brightness (typical) and 5 ms response time. The VG2428wm also indicates a 160-degree vertical viewing angle (170 degrees horizontal), but we noticed this display was more prone than most to losing text clarity at only moderately elevated heights from center. Unless testing reveals some unexpected surprises, we’ve been more impressed by other Viewsonic models.
