The set on this page is a used 85-inch TCL 85QM8K. It is a QD-Mini LED QLED 4K television with a native 144 Hz refresh. TCL QM8K Black Friday deals are deals on TCL’s QM8 series mini-LED television for the K generation of that line. TCL’s habit is to keep the QM8 name and change the letter by year, so a QM8K is not a QM8 from an older season, and it is not a QM7 or a QM6. The QM8 class is the brighter mini-LED set TCL aims at people who want a lot of screen for the money, with local dimming rather than an OLED panel. You are not buying Samsung’s S95 series. You are buying a specific TCL.
Size is most of the decision. These sets are commonly discussed at 65, 75, and 85 inches, and sometimes smaller or larger. The inch number in the title is the product. A Black Friday percentage on an 85-inch does nothing for a room that fits a 65.
What the QM8 name is promising
Mini-LED in this class means a full-array backlight with many dimming zones, which is how a non-OLED TV gets closer to a deep black and a bright highlight. The zone count, the peak brightness, and the refresh rate are printed on TCL’s page for the QM8K and they differ by size. Use those figures for the size you are buying. Do not copy a review of a QM8 from two letters ago. The letter is the generation. A higher zone count is not a moral victory if the processing looks bad to you in a store. If you can see a floor model, look at a dark scene with subtitles and at a sports ticker. Blooming around bright text on a black background is the thing mini-LED still does. OLED does less of it and costs more. That is the trade.
The panel is a 4K LCD. Refresh rate on TCL’s upper sets has been 120Hz or a 144Hz class on recent QM8 years. Confirm it on the QM8K. Motion and game mode matter if a console is attached. HDMI port count is the practical spec people skip. You want enough HDMI 2.1 ports for the devices you actually own, not a single good port and three older ones if you have two consoles and a receiver. Read the port list. A soundbar using eARC takes one port’s job. Plan the chain.
The smart system on recent TCL sets has been Google TV. Confirm that for the QM8K, because a store brand or a region model sometimes differs. Google TV means the Google app set and a Google account, with a home screen that promotes content. You can use an external streamer if you hate the interface. The remote and the power cable are in the box. A wall mount usually is not. Feet style varies. Measure the distance between feet against the console you own. An 85-inch set with wide feet and a narrow cabinet is a set you cannot put down.
Build and reflection are ordinary TV issues. A bright room wants you to stand at an angle and look for a mirror finish. Some QM8 years have been glossier than others. The spec will not say “annoying in a sunny apartment.” Your eyes will. HDR formats should be listed. Dolby Vision and HDR10+ support have varied by TCL year. If you subscribe to a service because of one of those formats, confirm the QM8K lists it.
TCL QM8K Black Friday: Black Friday Deals 2026 buying advice
Choose the size with a tape measure and a seat, not with the largest percentage off. Black Friday Deals 2026 will push the biggest QM8K because the dollar figure looks dramatic. A set that overwhelms the room is not a bargain. Sit at your real distance. If you are upgrading from a 55-inch, a 65-inch is a large jump and a 85-inch is a different living room.
Compare the QM8K with a QM7 only on purpose. The QM7 is the step down: usually fewer zones and a lower price. It can be the right TV. It is not the QM8K. An OLED from LG or Samsung is the other direction: better blacks, different warranty worries, higher price. If you have already decided mini-LED is what you want, stay in the QM8K sizes and stop opening OLED tabs that make you miserable.
Delivery and the first-power check matter more as the box grows. Photograph damage before you unpack if the carton is crushed. Power the set and look at a solid gray or solid color for cracks and bright spots. Mini-LED zones that fail can show up as a stuck bright patch. That is a return, and it is easier before the holiday return clock runs out. Keep the box if the seller requires it. An 85-inch box is a storage problem you should accept in advance.
Sound will be thin. Plan on the television speakers being enough for news and not enough for a movie. A soundbar is a separate purchase unless the bundle names a model. Do not let an unnamed bar decide the TV.
Once the set is in place, switch off any retail demo settings, pick a picture mode you can stand in the evening, and run the console or the streaming device you actually own through the HDMI port the spec sheet calls the high-speed one. Watch a dark scene with white subtitles for blooming, then a bright window scene for glare. If a zone is stuck bright, photograph it and use the return window. Mini-LED is allowed to look slightly different from OLED. A stuck bright patch in the corner is a defect, not a setting to live with.
Check the current listing for TCL QM8K and the inch size, then read zones, refresh rate, and HDMI ports for that size. Black Friday is a sound time to buy this set when the letter is K, the size fits, and you have seen or accepted how mini-LED handles subtitles. The badge QM8 alone is not enough. The K is the model.
