LG UltraGear 27G850A Review

Quick Summary

The UltraGear 27G850A is a 27-inch 4K gaming monitor from LG built around one clever idea. It runs at 4K and 240 Hz for big, detailed games and films, then drops to a Full HD 480 Hz mode with a hotkey when you want maximum speed in competitive shooters. The Nano IPS Black panel brings deep contrast, DisplayHDR 600 and wide colour, and DisplayPort 2.1 prepares it for newer graphics cards. It is a premium buy at roughly ₹69,500 on Amazon.in, and it only makes sense with a powerful PC behind it.

Design & Build Quality

The monitor looks like a serious gaming display without shouting about it. The screen is virtually borderless on three sides, and a hexagon-style RGB lighting accent adds some character without spoiling a desk setup. The L-shaped stand is the smart part: it keeps the footprint small, which matters on the compact desks common in Indian homes, and it still allows height adjustment of 110 mm, tilt, swivel and pivot. That is a full set of adjustments that many gaming monitors in this class skimp on, and a 100 x 100 mm wall-mount pattern is there if you would rather free the desk completely.

At about 9.4 kg with the stand and 5.2 kg without it, this is a solid, reassuring piece of hardware rather than a flimsy panel. It is easy enough to place once, but you will not want to move it around often.

Display Quality

This is where the 27G850A earns its price. The Nano IPS Black panel is LG's answer to the one weakness of ordinary IPS screens: washed-out blacks. LG claims a typical contrast ratio of 2,000:1, double the usual 1,000:1 of a standard IPS display, and in dark scenes that shows as deeper shadows and better separation of detail than a regular IPS monitor can offer. Typical brightness of 450 nits and VESA DisplayHDR 600 certification give highlights some real lift, although DisplayHDR 600 is a mid-level tier and should not be mistaken for the dramatic HDR of the most expensive screens.

Colour is a strength. Coverage of 99% of the DCI-P3 gamut (typical) means games, films and photos look rich, and the monitor is colour calibrated at the factory, so it looks right straight out of the box. For someone who edits photos or video as a side hobby, hardware calibration support and LG's calibration software are a welcome bonus. At 27 inches, 3840 x 2160 pixels is a very sharp combination; text and fine game detail look crisp at normal desk distance.

Gaming Performance

The headline feature is Dual-Mode. Left in 4K mode, the panel refreshes at up to 240 Hz, which is unusual at this resolution and makes fast motion look far smoother than the 60 Hz or 144 Hz found on most 4K monitors. Press the hotkey and the screen switches to Full HD at up to 480 Hz, the kind of speed that competitive players of fast shooters chase. LG states that in this mode the picture is shown at the size of a 24-inch monitor, so the image gets smaller; that is a sensible trade for pure speed, and you can switch back whenever you want the big picture.

The quoted 1 ms (GtG) response time applies at the monitor's fastest setting, as with every gaming monitor, so treat it as a best-case figure. Variable refresh rate support is broad: AMD FreeSync Premium Pro, NVIDIA G-SYNC Compatible and VESA AdaptiveSync certification mean tear-free play whichever graphics card you own. The usual LG gaming extras are present too, including Black Stabilizer to reveal enemies in dark corners, a Crosshair overlay, an FPS counter and Dynamic Action Sync to reduce input lag.

The catch is obvious: driving 4K at anything near 240 fps takes a very powerful graphics card, so for most games you will run the screen well below its ceiling. The monitor is future-ready rather than something every gamer can fully use today.

Connectivity & Everyday Use

Connectivity is well planned for a modern gaming setup. The monitor has one DisplayPort 2.1 input and two HDMI 2.1 ports, so a PC and a games console can be connected together. Do keep in mind that current consoles top out at 120 Hz, so they will not use the 240 Hz mode. A USB 3.2 hub with two downstream ports and one upstream port lets you plug a mouse, keyboard or headset receiver into the monitor, and a 4-pole headphone output carries both sound and a microphone, with DTS Headphone:X virtual 3D sound for headsets. LG lists a headphone output but no built-in speakers, so plan on a headset or a separate speaker set. LG also does not list a USB-C port.

Features Assessment

The software side is helpful without being intrusive. The LG Switch app lets you save picture presets, apply them with a hotkey and split the screen into up to 11 layouts, which is handy for keeping a game, a chat window and a browser side by side on a large 4K canvas. Auto Input Switch moves to the active source on its own, Reader Mode and flicker-safe backlighting reduce eye strain on long sessions, and the screen carries TÜV Rheinland Low Blue Light certification (hardware solution). A colour-weakness mode and a user-defined hotkey round out a practical set.

Ease of Use

Setup is simple: attach the stand, connect the supplied HDMI, DisplayPort and USB cables, and the on-screen display and LG Switch handle the rest. The stand's height and tilt are smooth to adjust and the hotkey for Dual-Mode means that switching between 4K and Full HD takes a second. Wall-mounting is possible if you prefer a clutter-free desk. The monitor uses an external power adapter, which is a small inconvenience for cable management but common for this class.

Value for Money

At around ₹69,500 on Amazon.in against an MRP of ₹70,000, the 27G850A sits at the premium end of the gaming monitor market. You are paying for the combination of a 4K 240 Hz Nano IPS Black panel, a Full HD 480 Hz mode, DisplayPort 2.1 and a well-built adjustable stand. LG India's own page does not list a price for this model, so Amazon.in is the place to buy it. If you only game at 1440p or 144 Hz, you can spend a lot less and lose very little; the extra money makes sense only if you have the graphics card to use the speed, or you want a single monitor that can serve both cinematic 4K and fast competitive play.

Who Should Buy It?

Buy it if you own, or plan to buy, a high-end graphics card and you want one monitor for both visual showpiece games and fast competitive titles. It also suits enthusiasts who edit photos or video on the side and want accurate, wide colour without a second display, and anyone who values DisplayPort 2.1 for future upgrades.

Who Should Consider Alternatives?

Console-only gamers should look elsewhere, because current consoles cannot use the 240 Hz mode. Buyers on a tighter budget will do well with a 1440p or 144 Hz gaming monitor, and people who want the deepest blacks of an OLED screen should look at OLED models instead. If you need built-in speakers or a USB-C port for a single-cable laptop setup, check the specifications of other monitors before you commit.
