LG reveals their 34GK950G and 34GK950F Nano IPS G-Sync and FreeSync displays
At IFA 2018, LG has unveiled two gaming-oriented displays for ultra-high-end PC gamers, both of which offer resolutions of 3440x1440 and high refresh rate playback.
These two monitors are designed to cater to the opposing sides of the PC market, with the 34GK950G supporting G-Sync while the 34GF950F supports VESA Adaptive-Sync and FreeSync 2. Both monitors use an LG "Nano IPS" display, which used a flicker-free W-LED backlight with a KSF phosphor layer to deliver 98% coverage of a DCI-P3 colour space.
From here on, both monitors become very different, with the G-Sync variant supporting a 100Hz refresh rate and a 120Hz overclocked mode while the FreeSync version supports a full 144Hz refresh rate without any need to overclock. In modern displays, "Overclocking" refers to the limiting of colour depth, chroma or other bandwidth-heavy features to enable support for higher maximum refresh rates. This makes the FreeSync version of this display superior in terms of image quality, at least when compared to the G-Sync version when running at its overclocked 120Hz mode.
Why is the G-Sync version so limited? The 34GK950G only offers support for DisplayPort 1.2 and provides an 8-bit colour depth, whereas the FreeSync 34GK950F supports DisplayPort 1.4, which delivers the ability to support higher refresh rates without compromises. The FreeSYnc version also supports HDMI 2.0, while the G-Sync version only supports HDMI 1.4, suggesting that it doesn't use Nvidia's latest DisplayPort 1.4 complaint G-Sync module.
Both monitors support a peak brightness of 400 nits, which is low as far as HDR compliance goes, though it is enough to grant the FreeSync version a full FreeSync 2 certification. The FreeSync version also offers support for 10-bit colour depths (8-bit + FRC). Both models feature stand with tilt, height and swivel options, though the G-Sync version also features LG's "Sphere Lighting" system on the rear of the monitor.
Right now, the G-Sync version of this monitor is set to ship in November for an MSRP of €1399. The pricing and release date of the FreeSync version remains unknown, though it is expected to release within a similar timeframe.
