Monoprice Zero-G Slim 27" IPS Monitor Review
by Chris Heinonen on August 26, 2013 12:00 AM ESTDisplay Uniformity is measured using CalMAN 5.1.2 at 25 locations on screen. Every measurement is compared to the center reading, which is the reference point. Here the Zero-G does very well. I expected a far less uniform display than I got.
White level is very even, staying in the 90%-100% range over most of the monitor. Even viewing gradients and full-white test patterns on the screen I don’t notice issues with the uniformity here.
Black level has a larger uniformity issue. The upper-left corner suffers from a fair amount of light bleed. It is more bleed than I have seen from other displays, and is easily noticeable. The other corners are better, though the upper right is also a bit light. The upper-left is easy to notice in daily use.
Because of that bright corner, the contrast uniformity drops in that area. The right side of the display has better contrast than the center due to a lower black level on that half.
On our color uniformity test, the Monoprice is nearly perfect. The highest dE2000 error compared to center is 2.13, and even that is virtually invisible. Despite its low cost and some backlight issues, color uniformity is nearly perfect on the Zero-G.
I expected to see results that were more similar to the Black Uniformity on the Monoprice Zero-G, but the results on White Uniformity and dE2000 Uniformity are very impressive. I’m really surprised in a good way by these results.

Minor pedantic correction: lack of OSD and a scaler (plus the fact that there is only DVI as the sole supported input) keeps input lag and overall latency low, but the pixel response time of the S-IPS panel remains the same as before, i.e., "approximately 6ms or less (GTG)"Koblek - Tuesday, August 27, 2013 - link
Thanks for the correction blackoctagon:)blackoctagon - Tuesday, August 27, 2013 - link
In a recent BenQ review Chris claimed that he would review these if he could get his hands on a sample. At the time he seemed unaware of Overlord - he claimed that the only overclockable IPS screens were imports - so I hope he will eventually review these delightful monitors.That said, no I'm not aware of any 'official'/pro reviews, just lots of glowing user reports

I have a korean 27" and it is a solid monitor. I also have a Viewsonic VP2770LED and it blows the korean monitor away in terms of quality and image. The step up from a typical TN to the korean is enormous, but so is the jump from the Korean to a fully featured high end monitor. Something that is very important for some people is the PWM dimming. I had major issues with head aches using the Korean monitor daily, while the Viewsonic has been pain free.atx9307 - Monday, August 26, 2013 - link
If anyone is looking to make a purchase at Monoprice now through 9/15, use code EMP1166 to get the lowest pricing listed on the site :)borderdeal - Monday, August 26, 2013 - link
I bought a X-Star monitor from ebay. I also got a Eye-one Display 2 calibrator for $35 shipped from ebay. I upgraded from a 27" 1920*1200 TN monitor. The X-star is way way better in color and viewing angels as expected. But calibrating the monitors made a big difference in both monitors. Even in the TN panel that I was amazed and regret not buying the Eye-one Display 2 before.cheinonen - Tuesday, August 27, 2013 - link
FYI (and for everyone else), the i1Display2 hasn't been made for a few years now. It has a non-sealed optics design that is especially prone to drift. I compared mine (kept in a sealed bag with silica) to a NIST-certified i1Pro the other year and the i1Display2 had an average dE2000 error of close to 10.0. They can measure light output fine, but getting color accuracy from them after more than a year or two just doesn't happen due to the design.Impulses - Tuesday, August 27, 2013 - link
Any recommendations for a decent calibrator on a budget?borderdeal - Tuesday, August 27, 2013 - link
I think he is talking about this one but it is not cheap:http://www.amazon.com/X-Rite-EODIS3-i1Display-Pro/...
