A:Answer Question is vague. Upgraded to what or with what? It is a fully functional 4K smart TV with speakers, remote and stand, wall mountable and lots of inputs like USB, HDMI, A/V. There are no 4K video sources available or any TV streams yet easily to exploit its 4K capability. If one has a 4K video camera then perhaps one can check out its true 4K performance. The main reason I bought it is at the price point of $500, it had a very good video quality better than some known brand and an unbeatable mfr 4 year parts and labor warranty.
