Dynamic Action Sync
Minimize input lag with Dynamic Action Sync so you can catch every single moment in real-time.

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.

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

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
