I am using LG LH70YR from the last 6 months. Never ever felt an issue. Earlier i was on Samsung LA71 series. Had to tweak a lot to work on HDMI (the things suggested by Udit).
With this one, I can use my PC output on HDMI and get stuff crystal clear on the screen. I do not have another monitor and this TV is my only monitor. No underscan/overscan issues. Everything just perfect.
Also the 100Hz engine is just amazing when you watch movies. Puts so much a fluidity to the motion.
I bought it for 46K I guess. You can get it for like 38-39K now.
