A bunch of Samsung 4K TVs are up to $500 cheaper at Walmart through May 5

Next up is the Samsung 7 Series, which is slightly more high-tech than the 6 Series. For starters, the 7 Series offers better image processing, meaning you'll get a slightly more vivid picture and better colors.

Like the 6 Series, the 7 Series is available in a range of display sizes, and has a 4K resolution with HDR support. There's even a curved version of the TV. If you like the idea of the slightly more immersive experience, the curved version might be for you.

If you have a slightly higher budget, then it's worth considering one of Samsung's QLED TVs. While most of the TVs on this list use LED technology, which is fine in its own right, the Samsung Q70 series uses what Samsung calls "quantum dots," which essentially means that the TV can produce much higher contrast and much deeper colors. Safe to say, if you want an amazing image quality and don't mind paying for it, then the Q70 series is the way to go.
