TCL has introduced Mini LED TVs with more dimming zones and LG is producing amazing OLEDs. this article will compare two brands' flagship 4K TVs for 2023, the TCL QM850G MiniLED TV and the LG G3 OLED Evo TVs.

TCL's QM8 series will be available in 65, 75, and 85-inch sizes, along with a huge 98-inch model. This is the largest TV model ever to use Mini LED, enabling precise backlight control to output a quality picture even with the huge 98-inch screen.

The TCL QM850G MiniLED features a Bezel-less design with extremely thin bezels that won't distract and a minimalist, stylish look that blends into a variety of environments. The TV supports wall mounting, and its panel is not as thin as OLED. You can also use the Height adjustable stand (65-85" models only) to mount it on furniture. The stand is located right in the middle of the panel, so there is plenty of space for mounting the TV even on smaller furniture.

Although LG has dropped the Gallery moniker this year, we can still be pleased with the LG G3's artful appearance. Its panel is very thin and will look great when you hang it on the wall using the included Zero Gap wall mount. The TV is light enough that even one person can easily install it. It doesn't come with a stand, so you'll need to buy a separate floor stand or legs if you don't want to wall-mount it.


Like last year's G2, the G3 is available in 55", 65", 77", and 83" sizes, while the 97" size is only available in Europe.
