I know that televisions have been discussed before but I just upgaded from a 43” Sony Bravia to a new Samsung 65” QLED 4K set and I am amazed at the quality of the picture. I have no 4K source right now but am buying a new Sony 4K Blu Ray player. I watched Saving Private Ryan on Netflix last nght to test it out and the upscaling to 4K was beautiful even though the source was not technically a 4K movie. I use a 5 channel Denon receiver for the sound. I debated on an OLED model but just could not see that it was worth the price difference. Maybe if they were side by side then it would be more apparent. Ready for football season now.
