I purchased this monitor to replace an older 19" screen that was lower resolution. The larger 1080p display provides excellent resolution. It's not actually "borderless on 3 sides" because there's a 1/4" border on 3 sides. When using 2 monitors side-by-side, that leaves 1/2" between the two screens--better than most monitors in this class. By default, the monitor connects with the Mac at 75Hz, but the standard spec for this model is 60Hz. Visibly, it's not a difference for me. In the 75Hz mode, sometimes when the monitor wakes up after a computer sleep mode, there's a screen full of snow. This problem doesn't seem to happen in the 60Hz mode, so that's where I have it set.
The power button/joystick is directly behind the LG logo on the front and easy to miss. The manual isn't very clear on the location of the power button. Pressing the button quickly pulls up a menu that lets you adjust quick settings, the input (VGA or HDMI), picture settings and general information. There are lots of options for those who like to tweak their monitor. I have found that the default settings work very well.
The monitor base is very basic with a flat surface (to help reclaim some of the desktop space taken up) with a vertical tilt swivel on the monitor. For stand or wall mounting there is provision for VESA 75mm mounts.
[This review was collected as part of a promotion.] It's a great monitor, but whoever decided that after the picture appears, that there should be a 20 sec display for "accessibility & beep guide smack in the middle every time the blanks out for a second should have his/her head examined. It is a real nuisance. In a corner would have been better if it can't be turned off. At least the HDMI display is only 3 sec and in a corner, which is fine. Recently bought 3 monitors, 27" & 22" (2) and they all do this. Tempting to return them. Would like to hear back on this from someone.
