LG has introduced its new UltraGear trademark for gaming monitors, which are intended to complement its UltraWide and UltraFine-branded displays. Among LG's Ultra displays, the UltraGear LCDs will be specifically designed for gamers and will be equipped with features to match. The first two monitors in the new lineup will be the UltraGear 34GK950-series 34-inch curved displays, one with FreeSync 2 and one with G-Sync.

LG’s Nano-IPS Treatment Gets to Gaming Displays

Both UltraGear 34GK950-series monitors are based on LG’s 34-inch 3440×1440 resolution IPS panel, offering a 21:9 aspect ratio and 5 ms GtG response times. LG does not disclose curvature radius of the monitors, but considering their sizes and positioning, it is reasonable to expect something standard like 1800R or 1900R. Meanwhile, paired with LG's LED backlighting, the complete display can hit 400 nits of brightness and a 1000:1 contrast ratio.

The main thing about both UltraGear 34GK950-series monitors is LG’s backlighting featuring its Nano-IPS technology, which LG yet has to explain in detail. As the name implies, the tech relies on nanoparticles applied to the screen’s LED backlighting to absorb excess light wavelengths and improve intensity, purity, as well as the accuracy of the on-screen colors. Fine-tuning spectral output of backlighting enables LG to improve color reproduction and the company claims that both LCDs can display 1.07 billion colors while covering 98% of the DCI-P3 color gamut (which is a better result than that of LG’s professional-graded 31MU97-B, at least on paper).

In theory, adjusting backlighting spectral output should also improve contrast ratio: however the UltraGear 34GK950-series displays both are rated for 1000:1, which in normal for IPS-type displays. Meanwhile, both monitors carry VESA’s DisplayHDR 400 badge, which mandates rather light requirements for both HDR brightness and blacks/contrast ratio. By contrast, LG’s ‘non-gaming’ 32UK950 monitor featuring a Nano IPS backlighting announced last year features a 1300:1 contrast ratio and is DisplayHDR 600-certified, which means that it can hit a tunnel maximum limit of 0.1 nits max.

G-Sync at 120 Hz or FreeSync 2 at 144 Hz?

Moving on to the key difference between the two UltraGear displays: the UltraGear 34GK950G-B supports NVIDIA’s G-Sync dynamic refresh rate technology, whereas the UltraGear 34GK950F-B features AMD’s FreeSync 2. 

The UltraGear 34GK950G-B (G-Sync model) supports a native refresh rate of 100 Hz and can be overclocked to 120 Hz. It is unclear whether LG had to use a panel with such a refresh rate because it was compatible with NVIDIA’s G-Sync scaler, or it is a limitation introduced by the combination of the panel and the scaler. LG does not disclose the range of variable refresh rate.

By contrast, the UltraGear 34GK950F-B (the FreeSync model) supports a native refresh rate of 144 Hz, though FreeSync range is also unknown here. Besides a higher refresh rate, the 34GK950F-B is FreeSync 2 certified, which means that it supports Low Framerate Compensation, and select applications can tone map directly to this monitor's native dynamic range, reducing input lag and improving quality.

Gaming Specials

Since LG’s UltraGear 34GK950-series displays are aimed at gamers, the company has equipped them with a number of gaming-related features.

First up, both monitors are outfitted with techniques to reduce motion blur in fast-paced gaming actions in a bid to make them look sharper. LG does not say whether it uses NVIDIA’s ULMB method for the UltraGear 34GK950G-B and something similar for the UltraGear 34GK950F-B, but this scenario looks quite likely. ULMB inserts a black image between each video frame to reduce time each frame is displayed, therefore making everything look sharper. A number of display makers (ASUS, Acer, BenQ, etc.) have introduced a similar technology for AMD FreeSync-supporting LCDs, so LG could do something similar as well. In any case, both monitors advertise “1 ms motion blur reduction” feature.

Next up is LG’s proprietary Dynamic Action Sync (DAS) technology that reduces input lag by eliminating certain internal processing of the display. A number of other makers of gaming displays have introduced their input lag reducing techniques, so it is natural that LG wanted to add the feature to its UltraGear displays.

In addition, just like previous-gen gaming LCDs from LG, the new monitors support brightness presets for FPS and RTS games as well as the Crosshair feature. The only difference here is that the UltraGear 34GK950G-B features three presets for FPS and RTS genres, whereas the UltraGear 34GK950F-B supports the so-called Black Stabilizer technology that adjusts brightness in dark scenes. LG does not explain whether the Black Stabilizer simply ups brightness when it detects a dark scene, or uses a more sophisticated technique, but the point is that owners of the UltraGear 34GK950F-B will not get lost in dark tunnels of Doom or Metro 2033.

Same Chassis, Same Look, But There Are Differences

LG’s UltraGear 34GK950G-B and UltraGear 34GK950F-B monitors use the same chassis that features very thin borders on all sides and a stand that can adjust tilt, height, and swivel.

On the connectivity side of things, the monitors have DisplayPort and HDMI inputs (two HDMI inputs in case of the 34GK950F-B), a dual/triple-port UBS 3.0 hub, an audio input, and a headphone output.

The key difference between the G-Sync and FreeSync-supporting UltraGear 34GK950-series displays is that the G-Sync model has Sphere Lighting — a ring of RGB LEDs with six color settings — on the back. By contrast, the FreeSync model has red inlays on the back to emphasize its gaming nature, a method used by a variety of hardware manufacturers.

Pricing and Availability

LG does not disclose availability timeframe for its UltraGear 34GK950-series monitors; for the moment it's only saying that they are “coming soon”, which is a very flexible definition that may equally mean by holiday season 2018 or sometimes post-CES 2019. As for pricing, LG’s non-gaming UltraWide 34UC98-W featuring a WQHD resolution and a 60/75 Hz refresh rate used to cost $1000 (it is currently available for $800). Keeping in mind more advanced panels and higher refresh rates of the UltraGear 34GK950-series, we are definitely talking about prices that are north from the previous series.

    4k is 16:9 and would be 32". 34" monitors only come in 21:9 ultrawide, which is a 3" downgrade in vertical space vs 30" 2560x1600; and it's the increased vertical space that is generally why people want 16:10. You'd need to go up to ~41" in an 21:9 ultra wide to match the height; or 60" in 32:9. AFAIK neither of those options exist yet.

    What is really needed at this juncture is for the 38" monitors to increase in refresh rate and response times. All of the 38"'s are LG panels that have a native ms rate of 8. They claim 5 in fast-mode but that is not working out well by all accounts. So these 38s are 3840x1600, this is a sweet spot for pixel density, being around the 111 range. None of the 38's have G-Sync and i believe none have FreeSync either. There are only 4 of them. (Dell, LG, ASUS, Acer). There have been accounts of ghosting and banding and vidoes to prove it during video playback. This would leave a concern with games as well and that's what I would be using the monitor for. I agree that the 3" is a downgrade in vertical space on the 34 and thus I will not be interested in the 34 at all. I really do like the idea of a 3840x1600 because I am currently using a 27" ASUS 16:9 2K and the visuals are stunning in games and normal desktop usage. I want as close to that resolution (or slightly above 2K) that I can get. If they could get G-Sync, 4ms (native), 144Hz refresh, good # of nits, decent stand, thin bezel, & good benchmarks out of a 38" (37.5" true size), I would be ecstatic. Right now however, it's a frustrating waiting game. I'm guessing 2Q 2019 before i see anything like that.

    Um, why are there LEDs on the back of the sets? I usually only see the back of my monitor when I'm first setting it up or the unlikely event that I'm dusting back there.

    The point is for the lights to reflect off the wall behind the monitor. It will make any professional office setting look like a super cheap strip club.

    It's a check-box "feature" for 12 year old "gamerz". I can't figure out why, but I assume since all OEMs are adding these garish lights it boosts sales somehow.
