Questions about 50″ vs 70″
Is 70″ worth it over 50″?
Yes if you want noticeably more picture: the 70″ has 96% more screen area than the 50″. Whether it's worth it comes down to budget and how far you sit.
Will the picture quality change?
Picture quality depends on resolution and panel, not size — a larger screen just spreads the same pixel count over more area, so pixel density drops unless you also step up in resolution.
Do these sizes include the bezel?
No — both figures are for the visible screen only; real cabinets run a few centimetres larger on each side depending on the model.
