TCL QM7L vs QM7K: Is the 2026 Model Worth It?
The QM7L replaces the QM7K as TCL's mid-range Mini-LED. Its big change is SQD, new quantum dots that labs measured covering far more colour, and it is brighter. But reviewers also found it less accurate out of the box, and the gaming hardware is the same. Here is how the two compare at 65 inches.
The TCL 65" QM7K is no longer sold. This comparison stays here as a record for owners and anyone weighing up these models.

Verdict: For anyone shopping now, the QM7L is the one to buy: it is TCL's current model, RTINGS rates it "a bit better than the QM7K overall", and it is brighter and much more colourful. If you already own a QM7K, there is little reason to upgrade: it is the more accurate TV out of the box, with the same two HDMI 2.1 ports and the same 144Hz refresh rate.

Brightness figures: the QM7K's is Tom's Guide's measurement of the 65-inch; the QM7L's is the same lab's measurement of the 75-inch, because no 65-inch figure has been published.
What Changed, Category by Category
Colour QM7L Wins
This is the QM7L's headline upgrade. TCL calls it SQD: improved quantum dots plus a new colour filter. In Tom's Guide's lab the QM7L covered about 90% of the Rec.2020 colour range against about 79% for the 65-inch QM7K, a big jump that puts it close to far more expensive TVs. Tom's Guide later named the QM7L its top Mini-LED TV of 2026.
Brightness QM7L Wins
The QM7L is brighter, though the published numbers come from different sizes. Tom's Guide's lab measured about 1,730 nits on the 65-inch QM7K and about 2,270 nits on the 75-inch QM7L (10% HDR window, Filmmaker Mode). Digital Trends saw the same direction: roughly 2,000 to 2,400 nits on the QM7K and about 2,800 on the 85-inch QM7L. TCL rates the 65-inch QM7L at up to 3,000 nits.
Accuracy Out of the Box QM7K Wins
The extra punch came at a cost. Digital Trends measured an average SDR colour error of about 2.6 on the QM7L against about 0.8 on the QM7K, and RTINGS says the QM7L overbrightens HDR content much more than its predecessor. If you want a natural picture without adjusting settings, the older TV was better. If you are happy to spend a few minutes in the picture menu, the QM7L's wider colour gives it more to work with.
Local Dimming Too Close to Call
TCL's headline zone count went down, from "up to 2,800" on the QM7K to "up to 2,100" on the QM7L, but those are the maximums for the largest sizes. TCL gives 1,152 zones for the 65-inch QM7L and pairs them with a new backlight controller; we could not find the 65-inch QM7K's count. Reviewers praise the QM7L's blooming control, and Tom's Guide noted only slight blooming off-angle. Without matched data, we won't declare a winner.
Gaming Tie
The gaming hardware barely changed. Both run at 144Hz with two full-bandwidth HDMI 2.1 ports (TechRadar), VRR and ALLM. On the QM7L the other two ports run at 4K/60Hz, and the soundbar connection (eARC) sits on one of those slower ports, so both fast ports stay free for consoles. Input lag on the QM7L measured about 9.4ms. RTINGS found the QM7K's motion slightly clearer in games.
Overall QM7L Wins, Narrowly
RTINGS sums it up as "a bit better than the QM7K overall". The QM7L is the more impressive TV in a showroom and in HDR; the QM7K is the calmer, more accurate one. TCL kept the launch price the same as the QM7K's, according to Tom's Guide and TechRadar.
Who Should Get Which?
Get the QM7L if...
- You are buying now and want TCL's current mid-range Mini-LED
- Colour and HDR punch matter most to you (see our best Mini-LED TVs)
- You have one or two consoles and want 4K/144Hz gaming (see best TVs for PS5 and Xbox)
Keep your QM7K if...
- You value an accurate picture without calibration
- Gaming is your priority: the ports and refresh rate are the same
- You are happy with its brightness in your room
Neither TV has a matte screen; reviewers found the QM7L's glossy despite TCL's anti-reflection claim. If glare is your problem, the Hisense U7 vs TCL QM7L comparison covers the matte-screen alternative.
Frequently Asked Questions
Is the TCL QM7L brighter than the QM7K?
Yes, but the published measurements come from different sizes. Tom's Guide's lab (shared with TechRadar) measured about 1,730 nits on a 10% HDR window in Filmmaker Mode on the 65-inch QM7K and about 2,270 nits on the 75-inch QM7L. Digital Trends measured roughly 2,000 to 2,400 nits on the QM7K and about 2,800 on the 85-inch QM7L. No lab figure for the 65-inch QM7L is publicly available.
Does the QM7L have more dimming zones than the QM7K?
TCL's headline figure actually went down, from "up to 2,800" zones on the QM7K to "up to 2,100" on the QM7L, but both are the maximum for the biggest size. TCL gives 1,152 zones for the 65-inch QM7L. We could not find a per-size count for the 65-inch QM7K, so a like-for-like comparison is not possible.
Should I upgrade from a QM7K to a QM7L?
Only if colour volume matters a lot to you. The QM7L's new quantum dots cover far more of the Rec.2020 colour range (about 90% against 79% in Tom's Guide's lab) and it is brighter, but the QM7K is more accurate out of the box, has the same two HDMI 2.1 ports and the same 144Hz refresh rate, and RTINGS rates the QM7L only "a bit better" overall.
Why do reviewers say the QM7L is less accurate?
Digital Trends measured an average SDR colour error of about 2.6 on the QM7L against about 0.8 on the QM7K, and RTINGS says the QM7L overbrightens HDR content much more than the QM7K did. The newer TV is more vivid but needs more adjustment to look natural.
Is the QM7L Pro the same TV?
No. The QM7L Pro is a separate model sold at Costco with four HDMI 2.1 ports. RTINGS reports other differences too, so do not assume reviews of one apply to the other.

We have not tested either TV ourselves; where a figure comes from a specific reviewer, it says so. Tom's Guide and TechRadar share one test lab, so their identical measurements count as one source.
