Power Consumption

The X270W’s primary focus really isn’t on energy savings, but Sceptre does deliver some surprisingly energy-conscious numbers. We measure power consumption using a Kill-A-Watt EZ at the wall while just displaying the Windows desktop at minimum brightness and maximum brightness.

The X270W’s nemesis is, surprisingly, the G2410H. The numbers are impressive, but keep in mind that the G2410H uses 11 watts while pushing a brightness of 78 nits to the Sceptre’s 18 nits. At its brightest, 293 nits, the Sceptre draws 44 watts. By comparison, the G2410H draws 23 watts at 311 nits. Bear in mind the size difference (24” versus 27”) and it’s clear that the X270W’s power per nit performance isn’t shabby at all.

    I really wonder whether this screen contains true 8bit per channel mask or whether it uses dithering to fake it...

    Usualy, TN panels are just 6bit per channel and remaining colours are faked using dithering or frame rate control.

    I wonder that too, and in all honesty it's likely 6-bit and dithered like you said.

    I'm still trying to figure out a good way to test - displaying the color pattern works, but there's still some dithering on even the highest end stuff I can find. Still trying to get to the bottom of it.

    I'm open to any ideas though! ;)

    the Sony G520 does 1024x768x120Hz. I recently bought one for $20 so i'm sure you can find one to test

    sorry, btw the g520 is VGA not DVI. i also had no luck finding a dvi crt.

    They're definitely coming ;) I'm working hard on getting a number of 120Hz panels in for reviewing pleasure ;)

    Stay tuned!

    Count me among those dissapointed in the resolution. That big has got to be at least 1920x1200. I know it's cheap, but would it really add that much cost?

    I bought a 20.1" Sceptre LCD above 4 years ago (for around $350, ughh...), which I'm overall pleased with. The only thing that bothered me, was really dark scenes, there was a fairly noticable criss-cross of light coming from the corners. I've heard the only way to truly avoid this was to get a LED-backlit LCD. How bad was this on the review unit? I didn't see mention of, but maybe you covered it and I'm just not familar enough with the terminology.

    Also, I'd like to see review(s) of some of the ASUS units, namely the VW266h (25.5" 1920x1200 for $250 AR right now) and the above mentioned ASUS MT276HE (27" 1920x1080 for $320 AR).

    Hey Anand and crew,

    Really digging all the reviews in the past couple of months and it is definitely helping me steer myself in the right direction for product purchases.

    Although this might delve into a realm that isn't your speciality, I would be very interested in inexpensive 32" LCD review for HTPC usage. I think this is a sweet spot that is neglected quite a bit, with reviews and suggestions jumping to 42" displays way too quickly.

    Keep up the good work and looking forward to whatever is in the review pipeline.

    Hmmz, there have been more than a few requests for us to take a look at some smaller (well, is 32" small? Small for a TV, large for a monitor, hehe) TVs and profile them against monitors. I've seen an increasing number of friends dropping their computer-LCDs in favor of LCD-TVs, so I think it'd be an interesting thing to take a look at.

    It's definitely something we haven't tackled yet. I've got a 32" Vizio of my own (oh boy, the irony of having such nice LCD displays and then two Vizio TVs - though they've improved significantly as of late) that I could try, hmmz. I'll see what I can fit in! Thanks for the idea/feedback!

    Anandtech/Brian, can you please please please review the DoubleSight DS-2700DW...I know a lot of people who are interested in seeing ONE review of this thing. I think at $399, it would be a nice comparison.
