What people are saying
Rated 4 out of 5 by from Great value. Was looking to buy a used monitor but when I saw the price on this I figured I'd take a chance on buying it. Performs well. Easy to install though the HDMI cable that came with the unit was defective. Only complaint is the on/off switch is used to a number of things that would best be on a menu. Despite that the monitor is a great value and I would buy it again.

Which LG monitors are compatible with a Mac (Mac Mini) computer?

Asked by: ABQGreg
Most, if not all of our monitors are Plug and Play monitors so they all will work with a Mac Mini. It's just a matter of connectivity and depending on what connections you have on your mac mini, you may or may not need adapters to make the necessary connections depending on what connectivity the monitor has...^IFV

Can this monitor be use as a computer monitor and cable TV?

Asked by: Dking174
The main difference between a monitor and a TV is that monitors do not have built-in tuners like TVs do and only a few monitors have built-in speakers. To use the LG 27" Class Full HD TN Monitor with AMD FreeSync (27" Diagonal), Model # 27MK400H to watch cable programming, your cable's Set-Top box will need to have an HDMI Out which you can connect to the HDMI In on the monitor and you will need to connect a pair of active or passive computer speakers to the monitor for sound since it doesn't have built-in speakers...^IFV

I have two camera systems, so can i input both a HDMI and dsub at the same time to this monitor? Can i split screen the two systems on the one monitor display at the same time?

Asked by: justin113
The HDMI port on the LG 27" Class Full HD TN Monitor with AMD FreeSync (27" Diagonal), Model # 27MK400H is a digital port while the D-Sub port on it is an analog port so the two ports are independent on one another. You cannot view two inputs simultaneously on this monitor, it does not support Picture-by-Picture. You can download the OnScreen software which has Screen Split 2.0 that enables you to resize and display multiple windows at once, with 14 options including four different picture-in-picture (PIP) choices...^IFV
