Results: Color Gamut And Performance

VP2770-LED Vs. S27B970D: 27" Monitors At 2560x1440
By

Color gamut is measured using a saturation sweep that samples the six main colors (red, green, blue, cyan, magenta, and yellow) at five saturation levels (20, 40, 60, 80, and 100%). This provides a more realistic view of color accuracy. Since there are no color management controls on either monitor, we're only showing the post-calibration graphs (although we’re sure they'd look pretty much the same out-of-box).

ViewSonic VP2770-LED

Color luminance is a little low for blue, red, and magenta, and the error increases as the saturation rises. Green, yellow, and cyan maintain almost perfect levels at all saturation points. The net effect on Delta E is small, with the exception of blue, which has visible errors from 40 percent and up. The other colors stay closer to or underneath the visible error level of three. This is a fair result.

Samsung S27B970D

Samsung's S27B970D measures noticeably better than the ViewSonic in its Standard mode. The only color showing any real inaccuracy is blue, but the error is slight. Again, this is mostly caused by its low luminance, especially at 100 percent. Aside from that, this is an extremely accurate panel. We did measure a slightly better result in the sRGB mode, but since this prevented us from correcting any grayscale error, we decided to stick with Standard.

Here is the comparison of post-calibration chromaticity error. Remember that a Delta E value below three is imperceptible to the naked eye.

All of the panels we’ve tested recently have no visible color error. Samsung’s average Delta E value is extremely low at 1.62 in the Standard picture mode. The factory-calibrated mode comes out a bit higher, with a Delta E of 2.69. Coincidentally, ViewSonic also turns out a Delta E value of 2.69. This is excellent performance.

Gamut Volume: Adobe RGB 1998

There are basically two categories of displays in use today: those that conform to the sRGB standard like HDTVs, and wide-gamut panels that show as much as 100 percent of the Adobe RGB 1998 spec.

The VP2770-LED and S27B970D fall into the former category, making them ideal for gaming and video content. Even out of the box, each screen's image will closely match the TV in your living room. If you require a larger color gamut for photo or graphics production, you’ll need to look elsewhere.

We use Gamutvision to calculate the gamut volume based on an ICC profile created from actual measurements. Given the premium price of the Samsung, we expected at least a wide-gamut option. But alas, there isn’t one. Both screens offer about the same gamut size as their competition.

Monitors that display more of the Adobe RGB 1998 gamut are generally priced higher. But they won't look as good in movies or games due to their higher color saturation. Unless the content is actually mastered using the larger gamut (and none presently is), it won’t display correctly on a monitor designed to conform to Adobe RGB 1998. So, it’s important to select a monitor based on its intended use, rather than the size of its color gamut.

    Why not do a review on those $330 Korean 1440P monitors that enthusiasts talk about? I like to see what i am missing with the extra $900. Really i'm serious i really want to know what justifies the 1 grand price tag.

    BigMack70I'm glad to see 1440p monitors getting some attention, but I just don't see the prices of these being justifiable to most users over the USA-based Korean 1440p IPS panels that are starting to become more numerous.$800-1200 is just nuts for anyone using these for home use or gaming, IMO.


    Agreed. I bought a Dell U2711 a few months ago, but if something forced me to replace it, I'd probably go with one of those cheap Korean panels -- or a TN panel 2560x1440 monitor if somebody would actually make one - I doubt I'm the only one who likes the resolution but isn't so picky about color quality. I had no objection to the color quality on my Samsung P2770HD, and the color shifts of a TN panel are affected by the physical size of the monitor, not the resolution, right?

    Dell's UltraSharp U2713HM is less than $600 in my country if we go by standard conversion. Would you guys say that's a good price?

    That's great to hear, I agree with the others that the price of these models is too much to consider unless they were generating $$$s for me. $3-400 seems like the range I would be willing to spend on these. And as for the USA based korean cheap models, are there any legit retailers of these? Please point me at them.

    Just bought a ASUS VS278Q-P for $310. It's a 60Mz monitor and I do game, but I'm happy. My previous monitor lasted 8 years (Samsung SyncMaster 213T, bought it for $1k). I'll upgrade when this one dies, hopefully 4k/UHD will be affordable. Supposedly, only serious gamers can tell the difference between 60Hz and 120Hz. I'm not a serious gamer, so it works just fine for me. 120Hz monitors of that size are nearly twice the price.

    Here are the inexpensive $300-$400 27" korean monitor brands: Yamakasi Catleap, Achieva Shimian, Crossover, PCBank, Potalion, Auria

    "The reason these monitors are cheap - LG makes IPS panels for apple cinema displays. Apple only accepts grade A+ panels. That means the all the grade A,A-,B+, etc are not accepted and returned to LG. LG resells those IPS panels to other manufacturers. You can get the whole story on google if you're interested. In addition, you're getting no support and no manufacturers warranty."

    It would be really interesting to get a review of these monitors that go for 50% or less of the price of the Big Brand stuff. If it's even 85-90% quality compared to the big brands, then they are worth the plunge. :D

    Personally, I was not impressed with the Auria monitor. My Acer HN274H TN monitor has better contrast. Viewing angles are far better on the Auria, but that's to be expected on an IPS. At any rate, I returned the Auria after a day of use because after many attempts to adjust the contrast/color, it didn't hold a candle to the colors or contrast on my TN. The Auria definitely had deeper black, but the in-betweens seemed to be missing no matter how I set the contrast and color. I honestly couldn't justify the tradeoff of higher resolution to lack of contrast. Maybe I got one of the LG B+ throw-away panels?

    Don't forget the Auria at Microcenter. Many Toms users, myself included, have them.

    I'm waiting for this or higher resolution in a 24" size monitor that has very, very narrow or no bezel, true 5ms response time and refresh rate of 120hz. Perhaps I'll live long enough to see one but I'm starting to doubt.

    I refuse to spend more than $400 on a computer monitor no matter what resolution it is running at.

    I just dont see QHD picking up any traction in the main consumer market until they get prices down to reasonable levels.

    Heck I can pick up two 1080p 23/24 inch panels for

    Hey Toms, you interested in an experiment where you cut off the bezels on 3 1080p monitors, and stick them together for a seamless experience ?

    I understand the reason why Windows 7 had Magnifier Tools just recently as I move on from 1366x768 to 1980x1200. And these things at even higher res, I don't think my focus is that good even with Magnifier Tool...

    Even with my recent resolution, I experienced some hard time to adjust myself when gaming is involved. The HUGE screen about 60 inch from my eyes still hurts my respond. I'm too focused on what happen on the middle of the screen and never had a chance to look at details on corners, when I do, it's already too late...

    I don't think I'm ready for such resolutions, even if someday my rig is.

    I have the Dell U2711 also. Im a very visually detailed person. Audio I cant tell the difference between low to mid, or mid to high end systems... but visually I notice. My friends and family dont notice visual details or color accuracy. They think my monitor was a waste of money, but I dont. You need to know yourself before making a purchase on these. Also, if your gaming, you'll need a beefy system.. the jump from 1080p requires more hardware than youd expect.

    I run a 3 monitor set-up; use it mostly for 3d modeling and CAD, and occasional gaming. 2048 by 1152 23" Samsung on the left; 32" Samsung TV in the middle and LG 23" IPS on the right.

    Want to replace this mess with 3 27" QHD IPS panels. VESA mounts are mandatory; minimal/no-bezel cases would be preferred. I don't see that combination of features available anywhere.

    Also at $700 - $1000 dollars apiece it would be impossible for me to get all three at the same time. I could swing the cash for three of the Korean panels but spending that kind of money on a scary warranty, quality gamble is a bit un-nerving.

    So I guess some comprehensive reviews of the lesser panels and comparisons to the name brand monitors would be extremely helpful for me at this point. I could have worse problems!

    This certainly applies to my 53-yr old eyes. I have two 1920x1080 monitors now, and I use the smaller one (21.5") on my primary PC because I am a little less likely to miss things than on the 23" one. Also, it isn't just the cost of the monitor; for games you're looking at $400-$600 price of graphics card(s) to go with it, plus a beefier PSU... I just can't justify it. I'm not knocking those who can, but I can't.
    I am happy with 1920x1080; I suspect my next monitor upgrade (unlikely to be soon) will be to get a 120Hz monitor for 3D, but not to get more real estate.

    More correctly, it's WQHD (2560 x 1440)
    QHD is more generally 3840 x 2160, but in regards to being 4x 720p, it's acceptable. Just not too... correct.

    For example, 720p shouldn't be HD if 1080p is HD. Like... 720 should have been 720miniHD but for marketing use, it's HD because HD is always good. So QHD is more reasonably 4x 1080p.
