27-inch 144 Hz IPS gaming monitor
The LG UltraGear 27G411A-B is a 27-inch flat-panel monitor built for competitive gaming. Its IPS panel delivers 178-degree viewing angles and covers 99 percent of the sRGB colour space. A 144 Hz overclocked refresh rate and 5 ms grey-to-grey response time target fast-paced titles. The display supports both FreeSync Premium Pro and G-Sync Compatible adaptive sync.
144 Hz overclocked refresh rate
The single specification that decides suitability is the 144 Hz overclocked refresh rate paired with a 1920 x 1080 resolution. Buyers whose graphics cards cannot sustain high frame rates at 1080p will not benefit from the panel speed. The 250 cd/m² brightness and 1,500:1 contrast ratio are adequate for SDR gaming but limit HDR impact. This monitor is not for users who need higher resolution or brighter HDR highlights.
Tilt-only stand and VESA 100 mount
Installation is straightforward: attach the stand for tilt adjustment or remove it to use the 100 x 100 mm VESA pattern. The package includes one DisplayPort 1.4 cable and one HDMI connection for video, plus a 3-pole headphone jack for audio pass-through. Common issues include forgetting to enable the overclocked refresh rate in the OSD and using a cable that does not support the full 144 Hz bandwidth.

Questions about this item
How does the 144 Hz (OC) refresh rate behave once the monitor is connected to a PC?
The panel runs at up to 144 Hz when overclocked, so fast-paced games show smoother motion than at standard 60 Hz, provided the graphics card can deliver matching frame rates.
What does the DisplayPort 1.4 connection cap in practice?
DisplayPort 1.4 carries the full 1920 x 1080 resolution at 144 Hz with FreeSync Premium Pro or G-Sync Compatible variable refresh, while the single HDMI port is limited to lower refresh rates at the same resolution.
What does the 100 x 100 mm VESA pattern mean for mounting this 27" screen?
The 100 x 100 mm mounting holes let you attach any standard VESA arm or wall bracket, and the monitor weighs 8.38 lbs with its stand or 6.39 lbs without it.
