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

So far we’ve only had the chance to test one 120Hz IPS monitor, Overlord’s X270OC. Now Monoprice has brought its G-Pro 120Hz 30-inch 16:10 screen to the fast IPS party. Today we see how it performs in our benchmark suite.

We’ve reviewed quite a few gaming monitors lately, and all but one were based on old-school twisted-nematic (TN) technology. While these panels offer all of the contrast, color accuracy and brightness of more contemporary in-plane switching (IPS) parts, they suffer from poor off-axis image quality. And in the 27-inch form factor, it gets harder to find that perfect sweet spot where the picture looks uniform from edge to edge.

IPS panels improve upon competing technologies in every area but one – speed. It seems that running one at refresh rates over 60Hz is something of an engineering challenge. Until recently, Overlord Computer was the only company stepping up to build a true IPS-based gaming monitor. Its Tempest X270OC fared extremely well in our tests last summer. We thought it would compel other vendors to join the IPS/gaming category, but sadly that didn't come to pass. Only Acer has joined in with its 27-inch XG270HU, a monitor we expect to have in our labs very soon.

When Monoprice announced its 120Hz G-Pro IPS 30-inch display, we were quick to request a sample. Not only does it offer extra speed, but you get a large 16:10 screen based on a well-engineered LG panel part with LED backlighting.

It’s interesting to note that Monoprice markets the G-Pro solely as a gaming monitor. If you look at the specs, however, it almost carries professional display cred. The GB-r-LED backlight enables wide-gamut operation. which Monoprice doesn’t advertise on its website. Then again, the extra gamut volume is unnecessary for gaming or typical computing tasks. We only wish there was an sRGB option in the OSD. You may have also noticed the 10-bit color depth. LG's panel is indeed natively 10-bit, though you need a full 10-bit signal path from your graphics card to take advantage.

That's not to draw attention away from the main reason we're here today: the G-Pro’s 120Hz refresh rate. Monoprice describes the screen as “overclockable” rather than simply rating it like other companies. What this means, as we quickly realized, is that you have to create your own resolution presets to enable refresh rates higher than 60Hz. And you can only use the DVI interface. DisplayPort has the necessary bandwidth, but it wouldn’t work for us at 120Hz.

We’ll lay our findings out over the next seven pages. In short though, while the G-Pro does work as advertised, it isn’t quite plug-and-play. What you do get is a wide-gamut display with reasonably fast panel response and low input lag. If that is your primary gaming requirement, and you want a large 16:10-aspect screen, this is the only game in town for now. Let’s take a look.

    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.
  • GObonzo
    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.
