What you need to bear in mind is that there really is little or no point having a 32" 4k resolution screen.

It's only when you get to larger screen sizes such as 50" / 65" / 80" / 103" / Edge Blended projection / Large Video walls and LED walls that 4k resolution comes in to play and really does add a noticeable difference.

You need space to have something this large to enjoy it and that is something that a lot of people now days don't have...Also think about how far in distance you need to be from it and how many people it is trying to serve.

So 4k resolution is actually Borderline living room viewing really depending on how big your living room is.

you will still get a great picture at full HD on a 42" or 46" screen. Yes you can still transfer a source scan at a higher resolution and compress it better, sharper and cleaner but in reality it's only when the pixels become apparent as dots on a large screen we need a higher resolution to compensate for this.

If you have a small screen with 4000 pixels you would just as easily glance over it as a HD signal as the detail would be too small to discern unless you put on microscopic goggles.
