By this level there is no query whether or not OLED-based TVs have the very best image high quality obtainable: they do. For my part they’re undoubtedly value the additional cash in comparison with different high-end TVs. The one query that issues is, in the event you can afford an OLED TV, which one must you purchase? LG is the OLED chief and its 2020 CX collection achieves as spectacular an image as any TV I’ve ever examined, however proper now it isn’t the very best reply to that query.
Higher image high quality than any non-OLED TV.Superior distinction and off-angle picture.Slim design and filled with options.
Do not Like
Costly.Not appreciably higher than cheaper 2019 fashions.
After reviewing the CX, the TV that I like to recommend most OLED customers purchase as an alternative is the LG B9 from 2019. I in contrast the 2 LG OLEDs side-by-side in my spanking new basement TV lab, and it was actually robust to inform the distinction between them in image high quality. My measurements sussed out some slight variations, and watching some low-quality materials gave a vanishingly small edge to the CX, maybe due to its improved processing.
However that is tiny potatoes in comparison with the massive worth distinction between the 2 proper now — $600 to $800 for the 65-inch dimension, relying on the place you store. The value hole will shrink because the CX will get discounted and the B9 sells out later this yr, however even then one other TV will stay inexpensive and sure a greater worth as effectively: the 2020 BX collection. Search for Proinertech’s evaluation of that TV quickly.
My different comparability TV was the TCL Eight-Sequence, which has the very best image high quality of any non-OLED TV I’ve just lately reviewed. It is a excellent performer and brighter then both OLED, however each the B9 and CX beat it for general image high quality. Each OLED TV I’ve ever reviewed reveals the true black ranges, infinite distinction and near-perfect off-angle efficiency that makes photographs come to life like no different TV know-how you should purchase.
Get to know the LG CX collection
It is pronounced “C-10” as a result of LG desires to be like Apple I suppose.It is available in 48-, 55-, 65- and 77-inch sizes. The 48-inch mannequin is new for 2020.As regular for OLED TVs, the 77-inch mannequin is proportionally dearer, at practically twice the value of the 65-incher. Competing 75-inch LCD-based TVs are rather more inexpensive. The 2020 CX provides just a few extras that the B9 is lacking, particularly an improved picture processor, compatibility with AMD FreeSync and a brand new Filmmaker image mode. In any other case they’re principally the identical.The one variations I famous between the B9 and CX are barely completely different stand designs and LG’s processing. As I discussed above, I do not suppose the CX’s slight picture high quality benefit is definitely worth the worth distinction.OLED show know-how is basically completely different from the LED LCD know-how used within the overwhelming majority of right now’s TVs, together with Samsung’s QLED fashions.The perfect LCD TVs I’ve reviewed up to now, just like the TCL Eight-Sequence and Vizio P-Sequence Quantum X, scored a “9” in picture high quality. At occasions they had been brighter in HDR than the OLEDs, however in any other case the OLEDs’ photographs had been superior in nearly each method.All OLED TVs are extra topic to each non permanent and everlasting picture retention, aka burn-in, than LCD TVs. We at Proinertech do not think about burn-in a cause for most individuals to keep away from shopping for an OLED TV, nonetheless. Try our information to OLED burn-in for extra.
Not a lot has modified with LG’s design. The panel on the B9, the CX and different current OLED units continues to be vanishingly skinny when seen from the aspect, a few quarter-inch deep, with a chunkier part on the backside that juts out one other 1.75 inches. That part homes the inputs, energy provide, audio system and different depth-eating TV parts.
From the entrance it is pure TV minimalism. There’s lower than a half-inch of black body across the high and sides of the image itself. Then there is a bit extra beneath, however no hint of silver, no “LG” or every other brand in any respect.
The CX’s stand is similar to the C9’s, its angled edges and medium width throughout the underside of the display. It is extra closely weighted than the B9 on the rear to (I presume) higher resist tipping ahead. That stated, I’ve by no means had any concern of the B9 tipping ahead, and I at all times advocate utilizing a TV security strap if in case you have youngsters.
Strong app and voice help
LG’s webOS menu system can be principally unchanged from final yr. It nonetheless lacks the progressive extras and app-based setup of Samsung’s Tizen system and falls effectively wanting the app protection of Roku TV or Sony’s Android TV. If you’d like extra apps, your finest wager is to get an exterior streamer, though solely a handful, together with the Apple TV 4K, Amazon Hearth TV Stick 4K and Nvidia Protect can help Dolby Imaginative and prescient and Dolby Atmos. In the meantime LG’s apps for Netflix, Amazon, Disney Plus and Vudu all help Dolby Imaginative and prescient and Dolby Atmos, whereas Apple TV app helps Imaginative and prescient however not Atmos. Utilizing the TV’s built-in apps will get you the highest-quality video and audio from these providers, no exterior streamer required.
The distant tracks the movement of your hand to whip rapidly across the display, one thing that is significantly useful when signing into apps or looking out utilizing an onscreen keyboard. The scroll wheel can be nice for shifting by way of apps, like these seemingly infinite thumbnail rows on Netflix and Amazon.
LG’s TVs are nonetheless the one gadgets that allow you to use each Google Assistant and Amazon Alexa. The primary mic button invokes Google Assistant whereas a long-press of the Amazon button will get you Alexa. Each can do all the same old Assistant stuff, together with management good house gadgets, reply questions and reply by way of a voice popping out of the TV’s audio system (yep, each voices). Fundamentals like “What is the climate?” works as you’d anticipate from both assistant, full with onscreen suggestions.
The CX additionally works with Apple’s AirPlay 2 system, identical to many different TVs together with 2019 fashions just like the B9. I used to be in a position to fireplace up my iPhone to share pictures and video to the display from the Pictures app in addition to mirror my Mac and cellphone screens. The LG additionally has the Apple TV app, after all.
HDR10 and Dolby Imaginative and prescient
The feature-packed CX consists of nearly all the things that issues in a contemporary TV. LG says the brand new A9 Gen three chip — included on the CX however not on the B9 or BX — has improved deep studying chops and “AI image Professional” enhancements. I did not discover any main advantages from the processor in my testing.
New for 2020 is the Filmmaker Mode, which takes the place of the Technicolor Knowledgeable modes of years previous. As promised it turns off the Cleaning soap Opera Impact for film-based content material (yay) however so do many different modes within the CX, together with Cinema, ISF and Dolby Imaginative and prescient itself (sure, this TV has a LOT of image modes). Whereas plenty-accurate it is also comparatively dim so I ended up utilizing Cinema and ISF Shiny for most important viewing.
All of LG’s 2019 and 2020 OLED fashions embody the newest model of the HDMI commonplace: 2.1. Which means their HDMI ports can deal with 4K at 120fps, help enhanced audio return channel (eARC) in addition to two gamer-friendly extras: variable refresh price (VRR) and automated low latency mode (ALLM, or auto sport mode). Try HDMI 2.1: What it’s worthwhile to know for particulars. I did not take a look at any of those options but for this evaluation.
Talking of VRR, the B9 and CX additionally help the Nvidia G-Sync commonplace. One distinction between the 2, nonetheless, is that solely 2020 fashions just like the CX may even help AMD FreeSync.
Bear with me, regular readers, as a result of there’s one ultra-technical downgrade on the CX in comparison with the 2019 C9. As reported by Forbes, the brand new mannequin’s HDMI ports help 4K at 120fps as much as 40Gbps (10 bits), whereas final yr they went as much as the total 48Gbps (12 bits). In an announcement, LG advised Proinertech that “the market scenario evolution indicated that actual content material that requires 48Gbps will not be obtainable out there.” The one gadgets that may look higher at 12-bit in comparison with 10-bit are next-generation consoles just like the PlayStation 5 and Xbox One Sequence X, however I would be stunned if it makes an enormous distinction.
The choice of connections is in any other case top-notch. Not like lots of Samsung’s units, this one really has an analog video enter for legacy (non-HDMI) gadgets, though it now not helps analog element video. There’s additionally a devoted headphone/analog audio output.

Image high quality comparisons
Usually I will evaluate a TV in opposition to 4 or 5 others side-by-side, however throughout coronavirus lockdown the scale of my basement — and restricted entry to comparability TVs — diminished that quantity to 2. Fortunately they had been two of the very best TVs of 2019, the B9 OLED and the TCL Eight-Sequence. As I discussed above the CX and B9 had been principally tied, with picture high quality that deserves a rating of 10/10, whereas the TCL fell a bit wanting each.
Click on the picture on the proper to see the image settings used within the evaluation and to learn extra about how this TV’s image controls labored throughout calibration.
Dim lighting: Lined up in my darkened basement TV lab, the CX instantly distinguished itself from the LCD-based TCL however not a lot from its sister LG OLED. Between the 2 OLED TVs I did not spot any main variations.
Watching the 1080p Blu-ray of Parasite, the trademark good black ranges and superior distinction of OLED had been an improve in punch and realism. Each scene benefited, however as regular the darker ones confirmed the biggest variations. Because the Parks focus on the transgressions of their chauffeur in Chapter Four, for instance, colours of their faces, garments and the encircling kitchen regarded, effectively, richer and extra reasonable. In extraordinarily darkish scenes like Park Dong-ik’s trip behind the automotive, the distinction was much more evident in a side-by-side comparability.
Shadow element was glorious on the CX and general darkish areas nonetheless regarded considerably extra reasonable than with the TCL. Professional tip: In my really helpful image mode, Cinema, bump up Brightness from 50 to 52 to reclaim these shadows whereas nonetheless preserving good black ranges.
Shiny lighting: No main adjustments right here: The CX was as brilliant as earlier LG OLEDs and considerably dimmer than high-end LCDs.

LG OLEDs from 2019 and 2020 have a setting referred to as Peak Brightness that enhances the sunshine output for SDR sources in Cinema and Knowledgeable modes. The concept is to extend distinction for brighter viewing environments whereas sustaining the superior colour accuracy of these modes. As with most TVs, the brightest mode for HDR and SDR (Vivid on the CX) is horribly inaccurate. For the correct colour columns above I used ISF Knowledgeable Shiny (Peak Brightness: Excessive) for SDR and Filmmaker mode for HDR — I like to recommend CX house owners do the identical to get good colour in brilliant rooms.
General, the OLED units are nonetheless lots brilliant sufficient for almost any viewing atmosphere. Sure, they do get fairly a bit dimmer than the LCDs when exhibiting full-screen white — a hockey sport, for instance — however even in these conditions they’re hardly dim.
The CX and B9 preserved black ranges and diminished reflections very effectively — higher than the TCL. I did not evaluate a Samsung immediately for this evaluation however prior to now that model’s high-end fashions have delivered the very best bright-room efficiency general.
Coloration accuracy: Earlier than my commonplace calibration, the ISF Knowledgeable, Cinema and Filmmaker modes had been already tremendous correct, among the many finest I’ve seen, and afterward the CX was as correct as I would anticipate. As regular, OLED’s superior black ranges additionally improved the notion of colour saturation in comparison with the LCD different shows. Shiny colours just like the fruit on the Parks’ countertop or the inexperienced of their yard in Chapter 11 had been lush and vibrant, whereas pores and skin tones just like the face of Mrs. Park remained true. I additionally appreciated that, in contrast to many LCDs together with the TCL on this comparability, the CX did not introduce a blue tinge to near-black areas.
Video processing: Watching the Parasite Blu-ray it was troublesome to see any processing benefits of the CX over the B9, maybe as a result of it is a very high-quality supply to start with. Searching for proof of the CX’s fancy new chip in motion, I attempted an previous favourite: Sport of Thrones’ The Lengthy Night time episode on HBO Max, streaming from an Apple TV 4K (set to 1080p SDR to match the native stream).
The opening setup of the military awaiting the approaching of the white walkers was rife with blockiness, banding and different compression points, in addition to primary video noise. However the CX did not clear it up significantly better than the B9. There was barely much less banding on the CX throughout a pan over Winterfell (5:19), for instance, and fewer near-black noise within the sky throughout the Dothraki cost (12:51) and when the solitary horse returns (13:47), however I needed to look arduous to identify the advance. And generally the B9 regarded higher; for instance it confirmed much less noise than the CX within the black sky round Sir Davos’ face (7:13). I am going to give the slight edge to the CX, however it’s actually refined.
With the Actual Cinema setting turned on, the CX handed my go-to 1080p/24 movie cadence take a look at from I Am Legend in Off, Cinema Clear and Person (Zero-Four for De-Judder and 10 for De-Blur) TruMotion place. The latter two additionally delivered the TV’s most movement decision (600 traces). For 2020 LG’s Person De-Judder setting is healthier than final yr, with extra of a variety for finicky cadence purists (we all know who we’re) to dial in the correct amount of smoothness; something Four or decrease launched some judder to my eye, conveying a way of movie slightly than cleaning soap opera impact. Clear alternatively is towards the smoother aspect, albeit nonetheless tolerable. Personally I want Person: De-Judder Zero however it’s nice that there is extra good choices than ever.
There’s additionally a setting labeled OLED Movement Professional, obtainable solely within the Person part of the TruMotion menu. In earlier years it was a easy toggle that launched black body insertion to enhance movement decision however with the same old tradeoffs of a dimmer picture and visual flicker. This yr it has 4 settings, Low, Medium, Excessive and Auto, with progressively higher movement decision, Excessive tops out on the most 1,200 traces in my take a look at however was fairly dim and flickery. Medium was the very best general, measuring barely much less at 1080 traces however with practically the identical mild output as Off and no flicker. The CX is the primary OLED TV I’ve examined that may match LCD TVs with true 120Hz refresh charges, such because the TCL Eight collection or the Samsung Q70, for movement decision.
The issue? Partaking any OLED Movement Professional setting apart from Off crushed shadow element and made the picture look too darkish. My recommendation is to keep away from utilizing this setting until you calibrate the picture particularly for it — otherwise you hate blur a lot that you just’re keen to sacrifice having the ability to see darkish areas clearly.
Gaming enter lag is just like final yr, which is to say excellent. The CX confirmed 13.7 and 13.Eight milliseconds in sport mode for 1080p and 4K HDR sources, respectively. That is shy of the C9 by mere tenths of a millisecond. Should you can inform the distinction, hats off to you.
Uniformity: Like all current OLED units, the CX was extraordinarily uniform in brightness and colour, with no seen variations throughout the display. As compared the LCD-based TCL all confirmed barely brighter and darker areas with full-field take a look at patterns, though it did not have main points. And as regular the 2 OLEDs had been significantly better at sustaining constancy from off-angle, when considered from seats aside from the candy spot proper in the course of the display. There have been no variations in uniformity between the B9 and CX.
Parasite is a good film that appears spectacular in 4K HDR.
HDR and 4K video: The 4K Blu-ray of Parasite regarded spectacular on all three high-end TVs, as anticipated, however the OLEDs had the benefit. The TCL beat them in brightness and spotlight pop, nonetheless. In Chapter three when Kim Ki-woo rounds a nook of the home (13:13), the solar measured twice as brilliant — 1028 nits vs. 540 on each OLED TVs — and the distinction was apparent to my eye.
Regardless of the additional brightness, nonetheless, the general distinction and richness of the OLEDs’ picture made the LCD look comparatively flat by comparability in lots of scenes. Within the standards at 30:51, for instance, there was only a bit extra pop and colour within the meals and the flower wrappings. And regardless of its glorious native dimming the TCL nonetheless betrayed some brighter spots in darkish areas, for instance the shadows behind the automotive at 30:14.
Wanting on the attractive nature footage from the Spears and Munsil HDR benchmark, the TCL’s increased brightness paid extra dividends than the cinematic Parasite. In my side-by-side lineup the LCD’s brighter skies, snow and different daylit scenes had been extra highly effective, particularly when a lot of the display was very brilliant — the desert sand, and vegetation at 5:20 was a great instance. The OLEDs did not look dim by any means however the TCL was higher in these brilliant scenes. In additional blended and darker scenes, alternatively, the OLEDs superior distinction once more received out.
Preserving with the character theme, I switched my Apple TV again to 4K HDR mode and checked out the amazing-looking Our Planet: Coastal Seas on Netflix. From the sensible colours of the reef to the darkish recesses behind the swarms of sharks I noticed the identical themes: an general edge to the OLED TVs regardless of the TCL’s brighter picture. Netflix’s nature documentary did not present as a lot HDR punch and element because the reference disc usually, and for that cause the TCL’s brilliance did not make as a lot of an affect. In some brilliant scenes just like the splashing seals (20:34), highlights just like the waves really measured barely brighter on the CX OLED, however in others just like the solar by way of the kelp (21:03) the TCL was visibly brighter and measured as such (1440 versus 660 nits).
