As colleagues write, but ... here we have to consider whether we want to have something modern or an older model without "fireworks".
Everyone has an individual approach to the subject, but it usually happens that every now and then the producers "make" us happy with some "news", which after some time turn out to be a "misfire". 3D, Smart, Qrwed etc. Unfortunately, if we want to have a better matrix, we have to buy and pay for these "inventions". For me, the OTV should be as large as possible (65 ") 4K, be able to record programs and as many movie playback systems as possible, and above all, a very good matrix (e.g. Q-LED). I am not interested in sound because I listen to it on a separate device, but it should be at least decent. OLEDs are still IMHO underdeveloped and you need to wait a bit until this technology "grows up". Of course, I will also be happy to pay for BT audio. I do not mention a few HDMI and USB sockets because it should already be a standard. Some voice control or I am not interested in remote controls with a cursor on the screen, but ... as I have already mentioned, the manufacturer forces the customer to buy them if he wants to have, for example, a better matrix. You must also be aware that such a new OTV will "live" for 5 years at most .
