There has never been a better time to buy a Samsung TV. That’s because most of the manufacturer’s televisions are in the discount corner for Cyber Monday, including everything from HDTVs and LED 4K TVs to 4K and 8K QLED TVs. With pricing starting at just $250 for a 43-inch and interest-free financing available to boot, there’s bound to be something for everyone.

One of the hottest sales today is a 70-inch Samsung 4K TV deal at Best Buy. See more discounts below:

So, what’s the difference between the top-of-the-line Q90R, the middle-of-the-road Q80R and Q70R, and the bottom-of-the-barrel Q60R? Aside from the obvious design differences, the most notable change is that the Q60R has an edge-lit backlight, so it can’t quite reach the same contrast levels as the other three — so it doesn’t make detail pop quite as well. But again, it’s miles ahead of a regular LED TV.

The Q90R, Q80R, and Q70R, on the other hand, all have what’s known as a full-array backlight, which can shut off sections of the screen to achieve a darker black level. What sets them aside from each other is the number of dimming zones each model has. The Q70R has a total of 48, versus the 96 on the Q80R and the 480 on the Q90R. All this means is the Q90R can shut off more individual parts of the screen to produce more accurate contrast.

It’s at this level that the differences will really only matter to die-hard film buffs. For the average viewer who’s just looking for something to tune into the latest must-see Netflix Original or maybe even a movie or two over the weekend, the Q60R is bound to impress. While those after the best viewing experience possible will have their fate decided by their budget — even on sale, there’s a considerable gap between the Q70R, Q80R, and Q90R.

If you’re looking for something bit different — maybe something from a different manufacturer — you’re in luck: There are plenty of other Cyber Monday TV deals happening right now.
