What People Are Saying

Rated 5 out of 5 by from AMAZING PC GAMING MONITOR! (Only 4ms) The following reasons are what make this monitor/TV great: A: Excellent gaming monitor with a Response Time of only 4ms! B: Great screen size support from 800x600 - 1920x1080. Unlike other monitors/TVs that only support 480,720,& 1080, this also supports sizes like 800x600, 1024 x 768, 1280 x 1024, 1366 x 768, & others. C: Great contrast with dark blacks and good color matching. D: Loaded with features including clear text & USB support for many media types including various video support with great picture quality and playback. E: 3 HDMI, VGA, Component, Composite, & Optical Audio output allowing for a great variety of devices to be connected. F: Descent ppi(pixel per inch) that I am able to use it as a PC monitor with sitting only 2'(feet) in front of it. It would probably be the largest size (42") a person would want to go without having support for sizes larger than 1080p. Icons, font, etc. is just the right size that they are not too small to see but also not too large that they look oversized.

Rated 2 out of 5 by from Faulty Motherboard Our LG tv was only 14 months old and the motherboard blew. Upon taking to our repair shop, he advised that the required replacement motherboard was incorrect. We have been without our tv for 3 months and was just informed it was ready. He had to call in LG service reps to figure it out. Now we have to pay for the repairs due to faulty installation from the start....................Go figure!

Rated 5 out of 5 by from Great Features Bright, crisp picture. Even the sound is better than expected. The setup out of the box is easy and simple. Menus are easy to use. We received this as a Christmas gift from my sister and her partner, this is not the one we would have chosen as we were saving for a 1080p and 120Ghz. I am surprised at the performance of this 60Ghz, no sluring during fast action sports. Great TV and I am blessed to have it.
