I want to view my images on a 40" HD Flatscreen TV. It's a couple year old Samsung 40". The jpegs I rendered look like crap on it. They are VERY grainy and look awful. Funny thing is that on an older model 720p HDTV, the images look fine with correct tonal representation. This older model can also be used as a PC screen. Is it because one is LED and the other LCD? That is, I think it maybe LED. I rendered original camera resolution from its highest settin (EM5 MKII) at 72dpi. What on earth am I doing wrong? I am at a loss and can't find a darn thing on the net. Help!
