If there is a way to set the resolution on the TV then it should be like a FHD or HD screen.My question is, how much of a difference will it be if they stream HD content on a 4K TV? As in will it be noticeable enough to care, or would they be able to live with it? The problem is that the internet is spotty at their location, so most of time they would be streaming at 720/ 1080 resolution.
I was looking at this Samsung 40" 4K TV for 28k or this slightly bigger 43" 4K TV for 37k.
But you will be paying for pixels you are not using.
