I see a lot of people saying OLED > 4k, but is that only for now? will you be upgrading to 4k lets say next year? im in desperate need for a new TV and i dont know whether to go "Future Proof" with a 4k now, because i dont really have the funds to get an OLED then 4k next year to say. Im hoping to have this new TV for years so i dont really want to be changing it after a year or 2 so is it worthwhile to just get a 4k one now? if so which are the best for around 500-700? Thank you.
