DoubleSight DS-277W: Back to the Drawing Board
by Chris Heinonen on June 13, 2012 1:30 AM EST27” panels so far have seemed to do better with display uniformity than smaller displays. The larger size requires a more powerful lighting system and in implementing this it has also been more uniform as well. Here the DS-277W does fairly well, with a couple of darker corners causing a drop but most of the screen staying fairly close to the 200nits we are targeting.
With a black screen the uniformity continues to be decent, with light leakage on one side but the rest of the display keeping close to the same as the center. This was a very good result for the black level in comparison to other displays.
Thankfully this performance does carry over to the color uniformity across the screen. It was established that at 200 nits the DS-277W was a good performer, and it looks like that carried over to the uniformity. The lower-left corner is a little off, but the rest are very close to a dE of 2.0 or below which is good. I will admit to being pretty surprised by how good the results were, but it seems that at 200 nits the DS-277W is a good performer.

Why would anyone buy an off brand monitor with a meager 1 year warranty for $950?When are they going to figure out there is a group of people that want once step above the catleap. US warranty and a 50% less fugly bezel and stand. for around $450

How come no large, IPS monitors use LED backlighting? I've been waiting and waiting for this feature. My office gets HOT and I'm trying to convert all lighting to LED and things that don't get so hot. My monitor is the last hot-box that needs to be replaced. For my work I require a large and high quality display, IPS.cheinonen - Wednesday, June 13, 2012 - link
The HP ZR2740w uses LED backlighting and is a 27", 2560x1440 monitor. Lots of the 27" and 30", higher resolution monitors are aimed towards graphics designers and other that are after the AdobeRGB color gamut, and I believe that in the configurations that LG offers the panels in you have your choice of LEDs with sRGB coverage or CCFLs with AdobeRGB coverage. Since people needing AdobeRGB are their target, that is much of the reason for using CCFL over LED I imagine.There might be other 27" or 30" models that use LEDs (Apple Cinema Display is one as well I believe), but I don't know them off hand.

That HP also has a constant control backlight instead of a PWM backlight so there is no flicker.I've been waiting for Anandtech to mention this in reviews. Some monitors have especially bad flicker, especially at lower brightness levels, because of the way they implement PWM.

"there was nowhere to put an internal power supply"Do you really do that?
It seems to me that these nice SmartTVs have all the hookups that computers need and the resolution is *starting* to match. With how thin they've gotten, it's questionable how monitor companies are going to continue their lines.

Why do we need Displayat all? There's nothing it can do that Dual-link DVI can't, as far as I know. It can steer my 1920*1080 120Hz monitor just fine.I don't get why everyone needs a new connector every five years. I know why VGA isn't up to todays standards, and I can see why one could want Thunderbolt (daisychaining isn't possible with DVI) even though I prefer to hook everything up directly. But DP is just another useless standard I don't want or need, just like HDMI. Don't want it, don't need it.

DisplayPort can drive multiple displays using a hub/repeater (if these are even available yet), use a much smaller cable over longer distances than DVI, carry audio as well as USB signals, has no royalty for VESA members (unlike HDMI which has a royalty still I believe), and is better suited for notebooks.DVI still works fine for most people, but as fewer people need analog support (one main advantage of DVI over DP) I'd expect to see DVI be replaced by DP for the reasons mentioned above. It's pretty hard to stick a DVI adapter onto a laptop at this point compared to MiniDP.

It gets rid of the TMDS, which is getting problematic in silicon. Further, DL-DVI pretty much maxes out at 25601600 @ 60 Hz. There needs to be something that supports a higher res and/or higher refresh.AdamK47 - Saturday, June 16, 2012 - link
The conclusion states: "there was no way to adjust the backlight that I could find"Did you go into the MISC menu and set ECO to 100? That gives full backlight brightness.

review that catleap monitor ;x
