Samsung and LG dominate the big HD flat screen category but...
Unfortunately they tend to be less compatible with other HDMI audio and video components especially for the CEC operation.
CEC is the system control software that handles the 1 button Power On and input modes. Samsung and LG rewrote their CEC software outside the standards, making it unreliable with other brand HDMI components. In our AV install biz we typically use the Sony flat screen products they are far more compatible but usually a few more $$..

Just my $0.02...
