LG C5 vs TCL QM8K — the OLED vs Mini-LED shoot-out
TCL's 2025 flagship Mini-LED TV offers incredible brightness and color performance at a reasonable price with myriad gaming features for those who need them.
LG's C-series has, year after year, proven itself as the best bang for your buck when it comes to OLED TVs. For that reason, among many others, the LG C5 OLED TV is one of the best OLED TVs you can buy right now.
But TCL is known for its budget displays, too, and the 65-inch TCL QM8K Mini-LED TV — its flagship model in 2025 — comes in at just $1,597. That's just $100 more than the 55-inch C5 OLED.
So which one should you buy? There's a lot to unpack when pitting the LG C5 vs the TCL QM8K. Here's how the two stack up and if it's worth shelling out a bit more for the OLED vs its Mini-LED counterpart.

Design-wise, the QM8K and LG C5 couldn't be farther apart. They're built on two completely different panels and screen types, with the QM8K using an LCD screen with Mini-LED backlighting and the C5 running on LG's WOLED panel.
Through these variances, you can also infer several aspects that make or break your decision when deciding between the LG C5 vs the QM8K. The biggest one is size and weight, as the OLED will be much thinner and less bulkier than its Mini-LED counterpart.
In fact, the LG C5 OLED weights 10lbs lighter than the QM8K at 36.6lbs. Luckily, they both share a similar pedestal stand in the 65-inch configuration, which is sturdy enough and can fit on most surfaces.
If you're worried about your sunny room becoming a problem, the QM8K might be the better option as it's equipped with an anti-glare coating. The C5 unfortunately doesn't have one, unlike the flagship LG G5 OLED TV, but LG does claim its "Bright Room Ready" feature diminishes glare just as well.
One of the major downsides against the QM8K TV is its lack of extra HDMI 2.1 ports. That's a real shame. TCL aims to make the QM8K the gamers' TV with tons of gaming features but that's hard to do with so few HDMI 2.1 ports. Meanwhile, the LG C5 has a total of four HDMI 2.1 ports, which means you have more options to choose from even if you're connecting an eARC compatible soundbar, like the Sonos Arc Ultra.
In terms of remotes, LG always proves the weakest link. The magic remote is an annoying gimmick that turns the clicker into a digital pointer. It's very annoying to use, but I still have to give LG some props for the redesign of its remote for 2025, as it's now less bulky and far easier to handle.
That being said, it's still not perfect. There's no dedicated input button on the remote, just one that acts as an all-encompassing smart home hub. Plus, with the select button in the center also serving as a scroll wheel, I tend to fudge the control and scroll all across the screen when I'm just trying to open an app.
No matter the case, both TVs will look just as good on a wall or stand in your living room. This really comes down to if you'd rather have a thin and light TV or something a bit heavier sitting on the wall of your house.
Winner: Draw

There's a lot to consider when looking at these two TVs side by side in terms of metrics.
The elephant in the room is brightness, which OLED TVs tend to lack. You can see here the C5 beats the QM8K in terms of SDR brightness, by just about 100 nits, but the Mini-LED TV blows the OLED out of the water with HDR content.
This should come as no surprise and it's definitely nothing to scoff at. The QM8K hitting over 4,000 nits in a 10% window is pretty impressive, especially when you consider its next closest rival, the Hisense U8QG, tops out at 3,916 nits.
But better brightness isn't what's selling TVs. Overall picture quality is the big ticket item, and the QM8K definitely will suffer when it comes to shadows and highlights. While we didn't note any blooming concerns on the QM8K, a real letdown was viewing angles, a problem that plagues most Mini-LED TVs.
If you're wanting richer blacks and finer details in darker environments, the LG C5 is definitely the one to go with. It also has incredible upscaling thanks to its Alpha 9 Gen8 processor, which can boost 720p to 4K with minimal artefacting.
Overall, it's simply hard to beat an OLED in the picture performance game. The QM8K definitely has some strong performance metrics and its brightness in HDR is some of the best we've ever tested, but the LG C5 is just too hard to topple with its inky blacks and improved contrast.
Winner: LG C5
In the world of smart TV platforms, Google TV tends to reign supreme. It offers an incredible list of features, many of the best streaming services, in tandem with tons of free channels to enjoy. It's genuinely hard to beat.
But LG's webOS has seen some major enhancements. While game streaming is still in its infancy, having easy access to Xbox Game Pass and Nvidia GeForce Now through webOS is a huge win in my eyes.
No matter which interface you end up choosing, you will have to deal with ads. It's important to note that LG is taking some steps to make webOS even more debilitating (and frightening) to use with ads served dictated by your emotions, but we're not quite there just yet.
For now, LG's webOS is a worthy compromise if you're hankering for a new OLED screen. Even if it's not up your alley, you can always tack on one of the best streaming devices, like a Roku Ultra, but given how snappy and easy-to-use webOS is, you might be fine living with webOS (for the time being).
What you might not be willing to live without is an ATSC 3.0 tuner. LG's axed the spec from its lineup since 2023, meaning none of its newer models have access to NextgenTV and 4K broadcasts. The TCL QM8K, on the other hand, does have one, so if you've got an antenna and want to watch live 4K TV, the Mini-LED TV might be the better pick.
Winner: TCL QM8K
You really can't go wrong with either TV when it comes down to gaming. While neither option here has that 165Hz refresh rate seen on several other 2025 models, their 144Hz support is more than enough for most gamers, especially when modern consoles top out at just 120Hz in 4K via VRR.
If you're planning on running a PC with your TV for gaming purposes, I'd recommend going with the QM8K. Unlike other TVs, it lets you drop the resolution to reach higher refresh rates, in this case 288Hz at 1080p. It's highly unlikely you'll find any games that run anywhere close to that, but it's an option if you're willing to sacrifice resolution.
Despite the higher refresh rate of the QM8K, games will look far better when played on the LG C5 OLED. Not only are OLEDs generally better for gaming, but LG TVs tend to be the best choice for the pastime. Plus, the C5 OLED can hit a low input latency of 9.1ms, which beats the QM8K's 13ms by quite a bit.
The QM8K has some neat gaming tools and features, but I'd still be buying the C5 to get the best possible picture performance.

There's a reason we typically recommend OLED TVs over their Mini-LED TV counterparts. They simply offer the best possible picture performance in the market and come with a range of features that suit most users.
The LG C5 is the poster boy for OLED TVs. It's a value proposition that's made better each year and the price will only diminish as we continue further into 2025. While you definitely could save yourself $400 by going with the 65-inch QM8K that's $1,597 right now, I would go with the more expensive option here.
Not only is the LG C5 OLED far superior in terms of picture quality and features, but we gave it a perfect score in our official review. It's one of the few TVs we've tested so far in 2025 to get that perfect rating, and not just among OLEDs.
If price is a concern, you can always go with the 65-inch LG C4 OLED TV that's currently $1,396 ($200 less than the TCL).
Overall, the TCL QM8K is a great TV and one that delivers great performance for the price. But if you want the best possible performance, you want the C5 OLED.

LG 5.1.1-Channel Soundbar Bundle Hits All-Time Low Only at Best Buy, Subwoofer and Rear Speakers Included
Living‑room movie marathons lose their sparkle when the dialog whispers, the explosions mumble, and the bass feels like a polite tap instead of a heartbeat. The LG 5.1.1‑Channel S70TR Home Theater Soundbar with wireless subwoofer and rear speakers aims to fix all that in one shot. Unbox it, park the slim bar under your television, and place the wireless sub and two petite surrounds behind the couch, then settle in for audio that wraps around you instead of drifting from a single speaker strip. Head over to Best Buy to get the LG 5.1.1‑Channel S70TR Home Theater Soundbar for just $400, down from its usual price of $500. That's a discount of $100 and 20% off. See at Best Buy The main bar hides a surprising nine drivers, including a center channel that keeps speech clear no matter how chaotic the scene, plus up‑firing units that bounce sound off the ceiling for Dolby Atmos height effects. Rain patters overhead, helicopters sweep past the sofa, and crowd noise rolls in from the stands, all while the wireless sub drops low notes you can feel in your chest. Two compact rear speakers round out the bubble, giving game night crowd chants and streaming concerts a genuine live vibe. LG's WOW Orchestra feature lets the bar coordinate with many LG televisions so the TV's built‑in speakers add extra lift rather than sitting silent, useful when you want even more front presence without cluttering the setup. Automatic room calibration pings the walls with brief test tones, then fine‑tunes each channel in under a minute, so the sweet spot lands where the coffee table already sits. If late viewing risks waking kids, Night Mode pulls back the bass bump and raises voices so every word stays intelligible at lower volumes. Connection options cover nearly any device. HDMI eARC carries uncompressed Atmos tracks from Blu‑ray players and modern streaming boxes, while a second HDMI input keeps a game console ready to roll. Optical and Bluetooth round out the list, the latter handy for quick playlists from a phone when the television is off. The remote places volume and sound mode buttons under a thumb, but Alexa and Google Assistant compatibility mean you can also say, 'Turn up the bass,' and the bar responds without hunting for the clicker. Movie lovers, sports fans, and casual listeners alike will notice the leap from flat panel audio to room‑filling surround the first time a theme song swells. The LG 5.1.1‑Channel S70TR Home Theater Soundbar is still available for $400 at Best Buy, a welcome drop from its regular $500 price. See at Best Buy

This OLED was just crowned the 'King of TVs' — beating, LG, Samsung and Panasonic
The Sony Bravia 8 II OLED TV stole the show in the 21st annual TV shootout hosted by Value Electronics this past Saturday and was once more crowned "King of TVs." The event brought together four of the best OLED TVs in a bout that covered color, brightness, contrast and more. The TVs up against one another included the Sony Bravia 8 II, Samsung S95F OLED, Panasonic Z95B OLED, and LG G5 OLED. Unlike last year, Value Electronics did not host a secondary panel for LCD screens (which Sony also won with its Bravia 9 Mini-LED TV) but, counting this year's win, Sony has won "King of TV" in some capacity for over seven years running. LG G5 OLED Samsung S95F OLED Sony Bravia 8 II OLED Panasonic Z95B OLED Contrast/Grayscale 3.69 4.38 4.41 3.84 Color 3.84 3.88 3.84 3.97 Processing 3.31 3.66 4.22 3.78 Bright Living Room 4.06 4.19 4.19 4.25 Overall 3.68 4.00 4.16 3.92 LG G5 OLED Samsung S95F OLED Sony Bravia 8 II OLED Panasonic Z95B OLED Dynamic Range/EOTF Accuracy 3.41 3.88 3.94 4.03 Color 2.84 4.13 4.03 4.00 Processing 3.34 3.72 3.53 3.97 Bright Living Room 3.94 4.38 4.19 3.88 Overall 3.30 3.97 3.88 3.98 To determine the victor, a panel of judges rated the TVs on their SDR and HDR performances, scoring TVs out of 5 in terms of their Color, EOTF accuracy, processing, contrast, and "bright living room" performance. You can find the results of the shootout in a PDF on Value Electronics' website, but we've copied the most important results above for your convenience. Although the Sony Bravia 8 II OLED won overall, which makes a whole lot of sense given how its test results blew us away, the Panasonic Z95B OLED was crowned best HDR TV at the show. That's a phenomenal win for a company that only just returned to the US market last year. (Note: Panasonic opted out of the competition in 2024.) Get instant access to breaking news, the hottest reviews, great deals and helpful tips. It's also interesting to see just how poorly the LG G5 did. It had some of the lowest votes in the shootout across most categories, especially in its color, processing, and EOTF accuracy, the latter of which is a test to see how accurately a TV reproduces brightness levels. Samsung's S95F OLED TV wasn't far behind in SDR, but even with that special anti-glare coating, the Panasonic Z95B still beat it in the bright living room category, which I found particularly intriguing. And on the HDR front, the S95F wasn't too far behind the Z95B, which beat it out by just one decimal point. While Sony wrapped up a win, Samsung and Panasonic put up a good fight.

LG C5 vs TCL QM8K — the OLED vs Mini-LED shoot-out
The C5 is LG's mid-range OLED in 2025. It delivers an incredible picture, a thorough collection of gaming enhancements and plenty of additional features.
