Uncalibrated – Maximum Backlight Level

Since the G-Pro 120Hz covers multiple segments (jumbo, gaming and wide-gamut), we’re including a broader mix in today’s comparison group. We have the recently-reviewed 30” IPS-LED screen from Monoprice along with the DoubleSight DS-309W 30-inch. Both are 16:10 with wide-gamut color. Also in the mix is Overlord's Tempest X270OC, the only other fast-refresh IPS display we’ve tested. Rounding out the field are two purpose-built gaming displays: BenQ’s G-Sync-capable XL2420G and LG’s 144Hz 24GM77.

Monoprice rates the G-Pro at 350cd/m2 but our sample measures slightly over 300. This isn’t a deal-breaker unless you really need a lot of output. There is no motion-blur reduction option to dim the picture, so the extra light probably isn’t necessary in most applications.

A max black level of .3543cd/m2 is an average result, putting the G-Pro mid-pack. The Overlord is on top due to its dimmer backlight and slightly higher overall contrast.

We’d like to see a little more contrast in a gaming monitor. This result does tell us that Monoprice is using a higher-quality panel for its 30-inch gaming screen though. Considering the G-Pro’s price premium, that’s a good thing. But for IPS fans, the Overlord 27-inch display provides slightly better contrast and black levels.

Uncalibrated – Minimum Backlight Level

The backlight control takes the image down to a level that's too dark for our tastes. Remember that the brightness slider works backwards; you have to lower it to raise output. To see 50cd/m2, set it on 90.

A dim backlight always produces great black levels. If you can deal with a fairly dark image, you’ll be rewarded with deep blacks and great shadow detail. It’ll just be difficult to see.

Contrast stays pretty consistent throughout the backlight’s range, with only a four-percent drop from maximum to minimum. This means the brightness control is correctly modulating the backlight and not affecting other image parameters.

After Calibration to 200cd/m2

The calibrated black level is also mid-pack. You can see that the two TN screens offer the best contrast, followed closely by the Overlord X270OC. You’re not giving up too much performance by going with the jumbo G-Pro display, though.

The final number takes a small hit because we had to lower the contrast control one click to tighten up grayscale accuracy. It represents a 10-percent drop from the max result. That's not too bad; it's still comparable to the competition, blowing away the other two 30-inch monitors.

ANSI Contrast Ratio

Given our contrast results so far, the ANSI test looks pretty good. If not for a hotspot in the lower-right corner, it would be even better. We’re still satisfied with the quality of this LG-based panel, and feel it has solid image quality and provides a good sense of depth.

    Generally a Monoprice fan, but the frame-skipping makes this monitor pretty unappealing for its intended market. Hopefully they can fix it with a firmware update.

    Monoprice is such a cheap-skate name. Why not chose a brandname less price concious like Lemon or something?

    I think this FINALLY is a step in the RIGHT direction. Sadly you cannot buy this in Europe.

    I was long ago looking for a 2560x1600 screen, and I got a Dell second-hand, because for whatever reason manufacturers ignore the customers, and they
    stick to 1080p. No offense to anybody who plays at 1080p, but you need to understand, that most people do productivity and game when they have too much free time, and they want to immerse into the game on a large screen.
    Personally I still love older games (Wolfenstein, FC1, Half-Life etc.) more than newer releases, and those run on these resolutions at any half-decent video card.

    Furthermore, nowadays even a 500Euro *MOBILE PHONE* can do above 1080p resolution on a tiny 6" screen, and for that money they give you 32-64GB of flash, 1GB of RAM and a quad-core CPU in a tiny box.
    Thus, I do not buy into this 1080p-1440p crap screen manufacturers are trying to shovel down at our throats for 1000Euros.

    At this point, I think an IPS gaming monitor is like SATAe... A technology that can be skipped because something better exists. Give me an OLED gaming monitor. LG makes a 55" 1080p OLED TV for $2000... why not a 24"-ish OLED monitor for under $1000? You'd have a ginormous color gamut, infinite contrast, true black, and response times <1ms. It's time for somebody to come out with an OLED monitor that doesn't cost $5500! (Sony PVMA250)

    I'm more of the type of consumer that likes products to work as advertised out of the box - i.e. 120hz IPS 1080p out of the box. I don't want to have to "overclock" it to its advertized settings, and then have it not work on the advertised ports.

    Any overclocking I do personally shouldn't be advertised on the box.

    Cool Specs, and I really dig the larger panel size

    ...that said, after using G-Sync for 6 months now I'm scratching my head as to why any manufacturer would make a gaming panel without G-Sync or Free Sync in it.

    Refresh induced stuttering and frame tearing shouldn't be acceptable in 2015

    Been gaming on a HP 30 inch IPS now for 5 years at 60hz. Its been worth every penny for $1200. I would steer clear of this off brand monitor regardless of 120 hz.
  • airborn824
    But that price is toooo HIGH!!
  • Eggz
    Close, but no cigar, MonoPrice. Looks like the Acer Predator XB270HU stays on top for now.
  • whimseh
    Yowza that is overpriced!

    The frame skipping CANNOT be fixed via a firmware update so don't be fooled by Monoprice's flat out lie! The frame skipping is due to the PCB connections used and the TCON - those issues are hardwired, silicon issues and there is no way a FW update can change that fact. This monitor is a FRAUD and should not be discussed as a 120hz monitor since it is entirely misleading to the average consumer thinking they found a holy grail 16:10 IPS panel that they could game on. The frameskipping issue should have been the LEAD on this story and the monitor basically tested as an impostor 120Hz IPS panel.

    Funny how people got their panties in a wad over the Nvidia 970 4gb 3.5gb issue claiming Nvidia are frauds (and leading to one lawsuit for false advertising I believe) and no one seems to make the same claims against MP here when the monitor CLEARLY is not a 120hz panel. MP should be forced to remove this from production or change its advertising as it is completely false.

    It would be nice if they had more monitor reviews. I'm interested in a 23"-24" ips that has a high Adobe RGB gamut (no banding like the 6/8 bit screens do).
  • juergenscht
    So Mr. Eberle didn't list 16:10 as a "Pro"? That guy is a complete pleb.
  • codo
    Stick with my ROG swift, thanks
  • SBMfromLA
    Well, it's down to $755.12 on Amazon now.

    For my personal opinion, so far the only true monitor I think that can compete in the gaming side of things that is a IPS with over 120 HZ is the XB270HU (albeit they seem to have some QA on some of the monitors....), at least they're making a step in the right direction.. Along with that, I know that ASUS announced some time ago that they were going to essentially remake their ASUS ROG SWIFT monitor except with IPS and 120 HZ. It's good to see though that more and more IPS monitors are coming out having 1440p+ 120/144Hz be the standard, also a plus if they have G-SYNC/FreeSync.

    I received an Acer Pred monitor and returned it. Hated the polarizer used and it looked muddy to me. I loved the features, but as an AHVA panel with the AG coating it just didn't match my other IPS screens at all - it felt I don't know kind of like a TN panel, which is a weird thing to say I know. I want only a glossy IPS - no coatings. Seems silly to slap a coating on an IPS screen since it does affect color and brightness when you view it next to a glossy panel. My Pred had a horrible white spot in the bottom corner, which was another reason for the return.
  • SkyBill40
    Uh, no. Given the frame skipping issues, this monitor is definitely a pass for me no matter if it's IPS and 120Hz+ or not. I'd much rather take a TN or AVHA paneled 144Hz monitor over this.

    the Freesync, 1440p, 27" ACER XG270HU is only 499.99 on Amazon now. too bad it's got the ugly red accents. blows this thing away.
