4K is absolutely retarded. TV isn't even 1080p yet, and game consoles BARELY reach 1080p AND.... a lot of people say they don't even notice the difference betwee 720p and 1080p.
Yet they're pushing 2160p? Who the fudge thought that was a good idea?
What companies need to do is push different models for different needs. All TVs seem to have compromises, but the compromises people are ready to make to keep it affordable isn't the same for everyone.
They have to make, for example, a TV that has ok image quality, with ok speakers, with ok smart features, for the average go. One that has the best image quality, but no speakers and no smart features for those who only care about image quality. Etc. make different products for different people! Now it's all or nothing. Either you have crappy image, with crappy sound, with no smart features, OR you have superb image, superb sound, way too much smart features and 3D and... and big fat price tag.
Personally, what I would want to buy ideally, is a display with the BEST image quality possible, with best motion resolution and input lag, etc. for gaming, but WITHOUT 3D, 4k, speakers, TV tuner, smart features, but no, if I want a good picture, I have to pay for all that crap I don't need.
