LG MP400 Full HD IPS Monitor, 75Hz
LG's MP400 is a Full HD IPS monitor offered here in two sizes: the 24-inch class 24MP400-B, with a 23.8-inch screen, and the 27-inch 27MP400-B. Both use the same IPS panel specification, with 178° viewing angles, 1000:1 typical contrast and a 5ms (GtG at Faster) response time, and run at up to 75Hz over HDMI. FreeSync smooths motion in games, Reader Mode and Flicker Safe keep long working days comfortable, and a 3-side virtually borderless design sits on a tilting stand. HDMI and D-Sub inputs connect a current laptop or an older desktop.
Quick Glance
Key Features
IPS Colour at Wide Angles
LG's IPS panel keeps colour reproduction consistent and lets you view the screen from wide angles, 178° left, right, up and down. Both sizes show Full HD at 1920 x 1080 with 16.7M colours, NTSC 72% colour gamut and 1000:1 typical contrast, behind an anti-glare surface.
Reader Mode and Flicker Safe
Reader Mode adjusts colour temperature and luminance to be closer to reading a paper book, to help lessen eye fatigue over long documents. Flicker Safe reduces invisible flickering on the screen, which helps reduce eye strain through a full working day.
FreeSync, DAS, Black Stabilizer and Crosshair
FreeSync technology virtually reduces screen tearing and stuttering in fast-paced games at up to 75Hz. Dynamic Action Sync reduces input lag, Black Stabilizer brings out detail in dark scenes, and Crosshair fixes a target point in the centre of the screen for better aim.
Detailed Specifications
Specifications as published by LG UAE on the product pages for the 24MP400-B and 27MP400-B. Where a figure differs by size, every size is listed, in LG's own wording.
Need-to-Know
Two sizes share this page. The IPS panel specification, inputs, features and stand are the same on both; what changes is the screen size, the footprint, the weight and the power draw.
- The 24-inch model is a 24-inch class screen: LG states its size as 23.8 inches (60.4 cm).
- 75Hz is over HDMI. LG lists the D-Sub input at 1920 x 1080 at 60Hz, so use HDMI for the higher refresh rate.
- Two inputs only: one HDMI and one D-Sub (VGA). LG lists no DisplayPort and no USB-C, so a laptop with only USB-C needs a USB-C to HDMI adaptor.
- No audio: LG lists no speaker and no headphone output for this model. Route sound through the computer or a separate device.
- The stand tilts only. For height or swivel adjustment, use the 75 x 75 mm wall mount with a monitor arm.
| Size | Model | Screen size | With stand (W x H x D) | Weight with stand | Power (typ. / max.) |
|---|---|---|---|---|---|
| 24" | 24MP400 | 23.8Inch · 60.4cm | 539.9 x 414.4 x 190 mm | 2.6 kg | 19W / 22W |
| 27" | 27MP400B | 27.0 Inch · 68.6 cm | 612 x 454.9 x 190 mm | 3.4 kg | 22W / 26W |
Both sizes are Full HD. The 24-inch class model packs the same pixels into a smaller screen for a sharper image; the 27-inch gives larger text and a bigger picture from the same sitting distance.

Frequently Asked Questions
Only the physical size. Both are Full HD 1920 x 1080 IPS panels at up to 75Hz with 250 cd/m² typical brightness, 1000:1 typical contrast, a 5ms (GtG at Faster) response time, the same HDMI and D-Sub inputs, the same tilting stand and the same 75 x 75 mm wall mount. The 24-inch class model has a 23.8-inch screen; the 27-inch gives the bigger picture and text.
IPS. LG lists the panel type as IPS for both the 24MP400-B and the 27MP400-B, with 178° viewing angles in every direction, so colours hold up when the screen is viewed from the side.
Connect over HDMI. LG lists the HDMI input at 1920 x 1080 at 75Hz and the D-Sub input at 1920 x 1080 at 60Hz. Set 75Hz in your computer's display settings after connecting over HDMI.
No. LG lists no speaker and no headphone output for this model. Sound stays on your computer, laptop or a separate speaker or headset.
Yes. Both sizes have a 75 x 75 mm wall mount, which fits standard monitor arms and wall brackets. The included stand tilts but does not raise, lower or swivel, so an arm is the way to get those adjustments.
