Our all-time favorite TV bargain is back for a limited time.

Right now, Best Buy is offering TCL's 65" 8 Series 4K Roku TV for $999.99. That's 50% off and the best price we've seen on this TV. If you want a bigger screen, Best Buy has the TCL 75-inch 8 Series 4K Roku TV for $1,799. That's $1,200 off and the second lowest price we've seen for this TV. What makes these 4K TVs a great deal is that the 8 Series is TCL's first premium TV with QLED technology, which delivers great picture quality.

Our review of the TCL 8 Series QLED Roku TVs showed that TCL has successfully combined technologies such as quantum dot enhancement and mini LED backlighting with a high-quality LCD to deliver great color and video processing.

The colors on the TCL 8 Series are very accurate and its performance rivals the best TVs on the market today. Fast action scenes were smooth on this set, with no discernible flicker or judder. In other words, people and objects moved quickly and smoothly on the screen.

Comparing the 8 Series side-by-side with the LG C9 OLED and Samsung Q80 QLED TVs, the TCL 8 Series holds its own. While overall picture quality may vary between competing models, we were impressed with how well the 8 Series handles near-black colors and dark shadows; it is the best TV TCL has released and a great buy for 4K TV fans looking to get the most value from their purchase.

These TVs won't be as discounted until Amazon Prime Day.
