Monoprice Zero-G Slim 27" IPS Monitor Review
by Chris Heinonen on August 26, 2013 12:00 AM ESTAll calibrations are done using CalMAN 5.1.2 software with an i1Pro meter and a C6 meter. Our targets are 200 cd/m^2 and gamma 2.2 for the pre-calibration and post-calibration measurements with the sRGB colorspace. We also try for 80 cd/m^2 and the sRGB gamma curve to see how well a display handles a more demanding professional setting.
| Pre-Calibration |
Post-Calibration, 200 cd/m^2 |
Post-Calibration, 80 cd/m^2 |
|
|---|---|---|---|
| White Level (cd/m^2) | 325.75 | 199.38 | 81.14 |
| Black Level (cd/m^2) | 0.373 | 0.335 | 0.322 |
| Contrast Ratio | 874:1 | 595:1 | 252:1 |
| Gamma (Average) | 1.309 | 2.195 | 3.051 |
| Color Temperature | 6744K | 6584K | 6648K |
| Grayscale dE2000 | 7.853 | 0.589 | 1.100 |
| Color Checker dE2000 | 7.611 | 0.942 | 1.000 |
| Saturations dE2000 | 5.413 | 1.083 | 0.995 |
Running the Zero-G at Contrast 50 and Brightness 50 with the sRGB preset, these are the best numbers I could obtain without a calibration. Since we are targeting 200 cd/m^2 and not 325 cd/m^2, that makes the numbers worse since we are expecting it to be 200 cd/m^2.
We see the gamma is incorrect and there are large grayscale errors. If I adjust the Brightness to 0 we see a gamma that is still wrong, and a blue color shift that gives us an average color temp of 8797K. The contrast ratio also falls to 580:1 and overall performance is worse.
If you only look at the Color Gamut chart, everything looks nice. Switch to the Saturations chart and you’ll see that the 40% red saturation target is past even where 60% should be. Blue and Magenta are over-saturated as well. The color checker chart confirms these saturation errors. This is why using only the standard gamut chart, as many people and print magazines do, provides little insight into actual performance.
Out of the box, the Monoprice Zero-G offers weird, strange performance that I haven’t seen in a long time. It also offers proof of why a panel in a monitor is only a small part of what leads to a quality display.
Calibrate the Monoprice and you have a totally different display. Look at the numbers and they are virtually perfect. If you are targeting 200 cd/m^2 you will have trouble doing better except with contrast ratio and black level. Those are still worse than what other monitors can produce.
Calibrate for 80 cd/m^2 and an sRGB target and you’ll see that performance isn’t quite as good as the 200 cd/m^2 target. The reason is the brightness control. Below are images from the CalPC client that CalMAN uses to calibrate. You can see the default line (in black) and the adjustments made to Red, Green and Blue channels for different output levels. Ideally these should track the default line.
On the Monoprice they start out much lower on the right. Because we have to correct for the brightness levels in the LUT, instead of using the display controls, we lose dynamic range and contrast ratio. The black level doesn’t change but the white level is dropping. We also don’t have as much room for adjustment for the gamma curve, which is why the sRGB one suffers.
CalMAN has corrected a lot of the flaws in the Monoprice compared to the default settings, but it has to take a large hit to contrast ratio to do so.

I do not doubt it is not a 100% accurate calibration for the problem u mentioned but for sure looks a lot better than the manual calibration I tried to do. I do not do anything professional with it so I do not need 100% color accuracy or even close to it so I am happy the way it looks and I compared it to the ICCs floating around for this monitor and I though the one done with the i1 looked better to my eyes (probably because it is wrong though)HisDivineOrder - Monday, August 26, 2013 - link
Really wish companies would produce the display hardware that would go with the IPS panels capable of pumping 120hz and give us a high speed, high frames per second IPS monitor. Even if we had to overclock it ourselves, just make sure the monitor can do it.That'd be worth it. This, not so much.

"Once you calibrate it, the Monoprice puts out a fantastic image. "I would say the same for my 24" Soyo Topaz, which is still running perfectly after 6 years. I just downloaded an ICC file from the internet, and a few small tweaks from there and the color was great. The only thing about my Soyo was that I did have a capacitor go bad on the power supply, and I had to order a $12 capacitor kit off Ebay to fix it. Having an external power brick actually sounds like a great idea for me as that would be very easy to replace.

I just got the monitor , i would like to know what your calibrations were besides brightness and contrast. I have never calibrated a monitor before and i would like to get the best experience with this monitorjb510 - Wednesday, August 28, 2013 - link
Glad you guys reviewed this, but hope you review the much higher quality Monoprice 27" IPS-Glass Panel Pro LED Monitor (PID 10489) which seem like a much better comparison to the Dell 2713HM.SeanFL - Wednesday, August 28, 2013 - link
Agree. Just bought two of the higher end monoprice 27 inch and am very impressed. They are bright and seem fairly accurate. Having displayport HDMI VGA and dvi is also nice.EMP1155 - Thursday, August 29, 2013 - link
On your next Monoprice purchase use promo code EMP1155 to receive 50+ pricing on all products. No limit to how many times you can use code. Offer ends 9/15/13Wellsoul2 - Thursday, August 29, 2013 - link
I've had the Catleap 2703 for awhile and love the color and resolution compared to a TN.I got it for $300 . The power switch doesn't always work on it after six months, but I don't care
I just switch off the power brick. (It still looks great)
I still would buy the cheap Korean one because of the price. If you want quality buy the Dell for twice the price because the $300 cheapie is probably the same as the $400 ones.

I know this is about the 27" MONOPRICE and this looks as if this is all old hashed-out stuff but.. I am going to put my two cents in for what it's worth. I purchased the MONOPRICE 30" IPS CrystalPro LCD Monitor WQXGA 2560x1600 Display last year 2013.07.13 and have been pleased with my purchase. So satisfied that I have not looked back, no wishes I had done something else, not one bit. Bang for the buck this PC Monitor is great. If you would like a complete in-depth review go here << http://toytalks.weebly.com/1/post/2013/04/review-m... >> ; If you are dissatisfied with the 60Hz RES then use a utility such as: Custom Resolution Utility [CRU] which will allow you to OverClock your 30" MONOPRICE IPS. I use my 30" piece of real-estate for work which requires rendering, AUTOCAD & some PHOTO work along with Word, EXCEL, Web Designing etc and last but not least GAMES. I utilize Dual SAPPHIRE Radeon Vapor-X HD 7970 GHZ OC 6GB and yes I can put the 30" MONOPRICE into the "Hurt Locker" in short order but that is not what I purchased this piece of real-estate for; I needed something that would be a good compromise over a broad range for different applications & this MONOPRICE 30" IPS definitely fulfills my requirements. So for what it's worth, if anyone is in need for a good all around large PC Monitor [30"] & does not have the out-lay of cash for the thousand dollar range then this is a good solid purchase.
