Monoprice G-Pro 30-Inch 120Hz IPS Gaming Monitor Review

Results: Viewing Angles, Uniformity, Response And Lag

To learn how we measure screen uniformity, please click here.

Viewing angle performance is the primary reason gamers are clamoring for more IPS options. The technology is certainly better than TN in this regard, but it isn’t perfect. The G-Pro shows a green shift at 45 degrees with a visible light falloff. Shadow detail holds up extremely well, however. In the top-down photo, there is a reduction in gamma, though you can still clearly see all the brightness steps. When a display is this large, IPS or VA is pretty much mandatory.

Screen Uniformity: Luminance

A 13.68-percent result suggests there is a little light bleed in our specific sample. The only hot spot we can actually see is in the lower-right corner. That zone is .05cd/m2 brighter than the rest of the screen, which is otherwise uniform.

Here’s the white field measurement:

The white field result is comfortably below 10 percent, which is our standard. There are no visible problems anywhere on the screen. You can see that the two TN-based monitors, while decent, aren’t quite up to the uniformity level demonstrated by the IPS displays.

Screen Uniformity: Color

We reviewed the DS-309W quite a while ago and weren’t collecting color uniformity data back then, which is why its result is blank. The G-Pro shows a little color shifting on the right side of the screen. While the rest of the zones look perfectly white, the three on the right show a subtle green tint. We’re nitpicking for sure; you won’t see a problem in real-world content.

Pixel Response And Input Lag

Please click here to read up on our pixel response and input lag testing procedures.

While the G-Pro 120Hz doesn't quite post the speedy response of a TN panel, or even Overlord’s IPS model, it’s still faster than the majority of 60Hz IPS screens. It is, however, also a little too slow to support the smoother motion one normally sees at 120Hz.

Here are the lag results:

The main draw of this monitor, besides its large IPS panel, is low input lag. It’s not quite as snappy as Overlord’s X270OC but only trails by a small amount. While you won’t experience super-smooth motion or minimal blur, response to user input is nearly as fast as the TN gaming displays we’ve tested.

Running at 120Hz

After setting up the G-Pro to run at 120Hz, we noticed that the movement of on-screen objects didn’t seem much more fluid. Usually it’s easy to see the difference between 60 and 120Hz. Here, we weren’t experiencing it. Thankfully Blurbusters.com has plenty of tests for evaluating blur reduction, overclocking and frame skipping. We theorized that the latter was our culprit.

The first test flashes squares in sequence on a grid. If every frame is rendered, a still picture will show several squares turned on consecutively. Here’s the 60Hz result:

Obviously the G-Pro runs just fine at 60Hz with no frame drops. Now check out what happens at 120Hz:

The alternating black and white squares indicate the G-Pro is dropping every other frame at 120Hz. We got the same results at 72, 85 and 100Hz as well. I spoke to a product manager at Monoprice and he confirmed our observations; it’s a problem they’re working on. It could be fixed by a future firmware update. But if you don't want to gamble, it might be better to wait for a next-generation product.

In short, you won’t see significantly smoother motion on a G-Pro running at 120Hz, but you will benefit from much lower input lag than a typical IPS monitor.

    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

    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.
