What people are saying

Rated 3 out of 5 by from LG 24MK400H-B Pros: Brightness is good Freesync Color Presets Game Modes Con: Changing response time in game modes can prove a choppy experience in all but normal mode. doesn't seem to be an advantage. My unit had an issue with the full top row of pixels flickering when using HD input. Sent for warranty claim. Freesync seems to struggle to keep up when using fast motion FPS games, ie quickly looking left to right.

Can we watch tv from this 22” monitor (IPTV with HDMI cable)

Asked by: Ary765
Unlike a TV which has built-in tuners and built-in speakers, the LG 22'' Class Full HD TN Monitor with AMD FreeSync (21.5'' Diagonal), Model # 22MK400H-B is a monitor so it does not have built-in tuners and it does not have built-in speakers. If you want to watch TV on the monitor, you will need to attach an external tuner and external speakers. The monitor has one HDMI input on it so you can also attach a Cable Set-Top box that has an HDMI Out to the monitor...^IFV

What is difference between 22MK400H-B and 22MK400H?

Asked by: Boki
There is no difference. Both model numbers are referring to the same monitor, the LG 22'' Class Full HD TN Monitor with AMD FreeSync (21.5'' Diagonal) Model # 22MK400H-B. The "-B" at the end of the model number indicates the color of the case on the back of the monitor (i.e. black). A lot of retailers do not use the "-B" and just list it as 24MK400H...^IFV

In the U.S., neither an HDMI cable nor a VGA cable come as included accessories with the LG 24'' Class Full HD TN Monitor with AMD FreeSync (23.8'' Diagonal), Model # 24MK400H-B.
