Ahhh yes, a new TV. It never is that simple anymore indeed.
HDR types, refresh rates, the type of panels used, the sizes only keep on growing (small sizes are rare these days for a good tv) ...
I'm moving this summer, so when we're done with the important stuff, we'd also be looking for a new tv. (I believe that it was already decided for me that it'll be a 'The Frame' haha)
