The LG 24GM77 ($349.99) is a well equipped 1080p gaming monitor that delivers speedy performance, accurate colors, and a host of gamer-friendly settings and features. It uses a 24-inch Twisted-Nematic (TN) panel with a 144Hz refresh rate, a 1-millisecond pixel response, and a Dynamic Action Sync (DAS) feature that reduces input lag. Its viewing-angle performance could be better, and it doesn't offer the variable frame rates and anti-tearing technology of our Editors' Choice, the BenQ XL2420G , but it is $300 less expensive and more than capable of handling your gaming needs.

Design and Features
The 24GM77 isn't overly flashy, but its black cabinet with red accents tells you that it isn't an ordinary monitor. The 1,920-by-1,080 panel has a non-reflective, anti-glare coating and is framed by thin (0.6-inch) bezels. The 8.5-pound cabinet is supported by a rectangular stand with a telescoping arm that gives you 4 inches of height adjustability. The hinge assembly provides 25 degrees of tilt and a 90-degree pivot range. The cabinet has four VESA holes for wall mounting. There aren't any speakers on this model, which is by no means a deal-breaker, since most monitor speakers are inferior to desktop speakers, but it may be a factor if your desktop space is limited.

Beneath the bottom bezel is a small control panel that holds two arrow buttons (left and right), a Black Stabilizer button, a Game Mode button, and a Dynamic Action Sync (DAS) mode button. The Black Stabilizer function lets you adjust black contrast to improve visibility in dark scenes, and the DAS button enables the Dynamic Action Sync feature, which is used to reduce input lag. The Game Mode button lets you toggle through seven gaming presets, including three Gamer modes that can be customized with varying Brightness, Contrast, Sharpness, Gamma, Color Temperature, Black Stabilizer, DAS, and Motion 240 (anti-blur) settings. There are two First-Person-Shooter (FPS) presets that are optimized for FPS games and one Real-Time-Strategy (RTS) preset that is optimized for RTS games.

Access to the menu system comes by way of small jog dial at the bottom of the control panel. Here, you can manually adjust the above-mentioned settings and fine-tune color levels using the 6-Color Hue and 6-Color Saturation settings. The jog dial is also used to select an input source and power the monitor on and off.

My Experience

I’ve been working with computers for ages, starting with a multi-year stint in purchasing for a major IBM reseller in New York City before eventually landing at PCMag (back when it was still in print as PC Magazine). I spent more than 14 years on staff, most recently as the director of operations for PC Labs, before hitting the freelance circuit as a contributing editor. 

The Technology I Use

I do all of my writing on my aging but trusty Lenovo Thinkpad T460.

At home I have two wireless networks running: one for streaming, gaming, and other day-to-day networking tasks, and another for testing all sorts of smart home devices including smart plugs and switches, lighting, indoor and outdoor security cameras, home security systems, air conditioners, smart grills, robotic lawn mowers, pool cleaners, and whatever else finds its way to my door.

It’s not uncommon to find people standing in front of my house taking video of a robotic lawn mower traversing my lawn during the summer months. Now if only someone would come up with a robotic snow blower, I’d be all set.
