I sit a decent distance from the TV (8 feet or so now from a 46" set) so it'd be fine I am sure for SDE.
One good thing is I re-calibrated my Samsung D630 last week and either I adjusted something in error since I last calibrated it 1-1.5 years ago or some voodoo magic has occurred as the image now is much better than it was before. I think I maybe changed the gamma setting by accident since then so I was running with too low a gamma and this new calibration corrected that. Since it looks really good right now I have less an urge to upgrade so I can wait it out and see what the hell this IMO pathetic industry is going to throw at us later this year and early 2015.
All I want is a freaking 55-60" TV with minimal annoying issues (banding, uniformity, IR...) and decent picture quality that is a clear upgrade to what I have now with the Sammy. You'd think this shouldn't be hard yet boom, it apparently is. Maybe OLED will be the way to go if the IR really isn't a big issue like it is on my VT25. I would prefer a flat guy yet I have my bedroom window behind where my TV is so I can't wall mount it like I believe that new flat LG model requires.
