24″ LG 24GM77-B – Full Specifications
The LG 24GM77-B is a 24-inch TN monitor built around a fully height-, tilt-, swivel- and pivot-adjustable stand that most budget 1080p monitors skip.
Overview
The LG 24GM77-B is a 24-inch TN monitor built around a fully height-, tilt-, swivel- and pivot-adjustable stand that most budget 1080p monitors skip. It runs Full HD 1920 x 1080 at 56 Hz - 144 Hz though it skips HDR certification. Brightness is rated at 350 cd/m² with a 1000 : 1 static contrast ratio, and the Anti-glare/Matte (3H) coating keeps reflections down. Connectivity is 1 x USB 3.0 (upstream), 2 x USB 3.0 (downstream), 2 x HDMI 1.4, and the stand offers height, tilt, swivel and pivot adjustment at 5.43 kg. Buy it if ergonomics and all-day desk comfort matter more to you than raw refresh rate; skip it if you specifically want the highest Hz number on the spec sheet, since faster 144Hz+ alternatives exist at a similar price.
Key Highlights
- Full ergonomic stand with 100 mm of height travel plus pivot and swivel
- 1000 : 1 static contrast ratio for a TN panel

HDR & Brightness Reality
The 24GM77-B does not carry any HDR certification. Its 350 cd/m² typical brightness and 1000 : 1 static contrast sit well below what's needed for a meaningful HDR image, so content will play back in standard dynamic range regardless of what a source device offers. If HDR video is a priority, look elsewhere in this lineup at a model that specifically lists HDR10 support.

Pros & Cons
- 144 Hz refresh rate is genuinely fast for the price point
- Full-featured ergonomic stand with height, tilt, swivel and pivot
- Slim 57.3 mm profile keeps the desk footprint small
- Anti-glare/Matte (3H) coating cuts glare in bright rooms
- No HDR certification of any kind
- No built-in speakers, so external audio is required
- sRGB coverage is not published, so colour accuracy is unverified
- Only 1000 : 1 static contrast, unremarkable for a modern panel
