40" / 43" 4k TV to replace Panny TX L37V10B? I still love the picture on my Panasonic 37" IPS Panel, which I've had for 6 years. Would like a slightly larger screen. 40 - 43". HD or UHD? Do I go for Panny 40CX680, Samsung 40 JU6410 or Sony 43 X8305C or 805C? Is the Picture Quality better on these new TV's? Hard to tell in Currys without tweeking each set!!!!!!! Or keep my current TV for another year or so while all the software is sorted? Don't need 3D or Netflix etc.
