Hey Road - 4k is twice the resolution and has 4 times as many pixels so its pixel density is higher giving you a more immersive watching experience. The Q60T does have the Quantum Processer 4K Lite that can up scale all your content to near 4K quality. I would suggest a 4k Blu-ray player as they will play DVDs , Blu-ray and 4K Blu-ray discs . ^ Jason
