LG B2 vs C2 OLED TV Comparison

LG B2 and C2 are parts of the LG’s 2022 OLED TV lineup. The C2 sits between the LG G2 and B2 while the LG B2 sits between the LG C2 and A2. You need to know, two years ago, whether it is lowest model or highest model, they use the same panel technology. Like last year, LG C1 and B1 or even A1 uses the same OLED panel technology. So, can be ascertained that they can deliver almost the same picture quality. Their difference is only on out of picture quality. But in this year, that all has changed. The LG G2 use a new OLED panel technology that also found on LG G1 in last year, which is evo OLED Panel. You need to know, LG Has claimed that the evo OLED panel can deliver brighter peak brightness. On the other hand, the LG B2 uses a traditional OLED panel that also found on the lower model LG A2 or most model in previous years.

Besides their panel technology, the LG B2 is also powered by less power image processor than the C2. If The LG C2 is powered by Alpha 9 Gen 5 images processor, the LG B2 is powered by Alpha 7 Gen 5 images processor. One of the advantages of the Alpha 9 Gen 5 is that it now delivers a Dolby Vision Upgrade. And of course, there are other advantages that offered by the LG C2 over the down-side model LG B2.

In the market, LG C2 comes with a lot of screen sizes options. It even is the OLED TV model that comes with the most screen sizes option. From the smallest, there are 43 inches (OLED43C2PUA), 48 inches (OLED48C2PUA), 55 inches (OLED55C2PUA), 65 inches (OLED65C2PUA), 75 inches (OLED75C2PUA), and 83 inches (OLED83C2PUA). On the other hand, the LG B2 comes in 3 screen sizes option only, which are 55 inches (OLED55B2PUA), 65 inches (OLED65B2PUA), and 77 inches (OLED77B2PUA). And with the same screen sizes, as the lower model, LG B2 is sold hundreds dollar more expensive than the LG C2. So, what advantages are offered by the LG C2 over the B2 OLED TV and which is a better choice?

Dark Room Performance

As we have known, all OLED TVs is very strong in dark room thanks to their infinite contrast ratio, pixel dimming level and nearly perfect black uniformity. As well as the LG B2 and C2, both also have great performance in a dark room. Unlike LED TVs that need backlight as their light source, OLED panel doesn’t need backlight thanks to their pixels that can emit their own light. And the great thing is that each of their pixel can work individually, which means each of them can switch on/off or dim without influenced by the condition of other pixel. So, when they are showing black, pixel in black area will be totally switched off, so there is no light at all emitted from their screen. That’s way the OLED TV including LG B2 and C2 OLED can produce nearly perfect black level and black uniformity. So, even if they are set in a pitch-dark room, black produced remains look really black. And of course, this also makes dark colors can be shown fairly well.

LED Vs OLED Black Dark Room

That is not only that, their individual self-lighting sub-pixel also makes them has pixel dimming level. This is equivalent to LED TV with Full Array Local Dimming that has the number of dimming zones is equal to the number of pixels. So, when they are showing small highlight in a dark scene, there are only pixels in the bright area that is switched on while the rest are switched off. The result, small highlight can be shown without blooming around it. And combination of all makes dark scene looks incredible with a lot of details and almost no “crushed black”.

Winner: Draw

Bright Room Performance

Performance of the LG B2 and C2 in a bright room may be not as good as premium LED TVs, but their performance is still good. And in this point, the difference in their OLED panel technology is influential. With SDR content, the LG C2 can gets brighter, which is around 425 nits while the LG B2 gets around is around 375 nits only. Ignoring their difference, their SRDR peak brightness actually is fairly good. As long as you don’t use them in a very bright room with a lot of window or lamps, their peak brightness is bright enough to fight the glare.

Furthermore, both also can handle reflection greatly, even reflections from strong light source. And this makes them doesn’t have any issue with reflection if you use them in a bright room. And of course, combination of their good SDR peak brightness and outstanding reflection handling makes them have great performance when used in most bright rooms.

Winner: LG C2

Picture Clarity

Although the LG C2 comes with an upgrade images processor than the LG B2, but both can do a very good job in processing images. Both have AI-based up-scaling engine and deep learning machine. Combination of these technologies allow them can up-scale low resolution to 4K quality fairly well. So, even though you play content with lower resolution like DVD movies with 480p or HD movies, you can enjoy them in 4K resolution with quality close to native 4K content without a lot of artefacts. And the higher resolution of the source like Blu-ray movies with 1080p resolution or native 4K content, the images displayed on their screen will looks much smoother with a lot of fine details.

Beside they have good up-scaling engine, both also have good gray uniformity. So, when they are displaying a content that has large bright area with uniform color, the screen looks very uniform without a lot of dirty screen effect. This is good for a content that has large area with the same color like sport field. Meanwhile, compare between them, the LG C2 is a bit better than the B2, but their difference is not very significant.

Winner: LG C2

Color Reproduction

Both of the LG B2 and C2 OLED have outstanding color gamut and their color gamut is almost similar. In DCI P3 color space where most of current HDR content are mastered, their color coverage is nearly perfect, almost 100%. This means, all colors of HDR images mastered in DCI P3 like HDR10 content can be shown fairly accurate. Sadly, their color coverage in Rec.2020 is only decent, where the LG C2 cover about 78% while the LG B2 cover around 77% of color space. This means, it is still good for HDR content that mastered in Rec,2020 like Dolby Vision Content, though, some certain colors may be not displayed accurately.  Sadly, their color volume is just decent. Both may be able to show dark shades of colors fairly well. But since the use of white sub-pixels desaturate bright colors, this makes them cannot produce very bright colors fairly well.

While their color gamut and color gradient is almost similar, the LG C2 has better color gradient than the LG B2 thanks to its image processor up-grade. On the screen of the LG B2, there is small banding in almost all shades of colors, even in shades of gray, banding is a bit noticeable. Meanwhile on the screen of the LG C2, there may be still a little banding in all colors, but it is less than the LG B2. Both actually have a feature that can help to remove banding called “Smooth Gradation”. Sadly, this only work well with low quality content while with high quality content, this precisely can cause some loss of fine details.

Winner: LG C2

Side Viewing Angle

Just like other models of OLED TVs, both of the LG B2 and C2 also have wide viewing angle. Black level of images look very consistent when viewed from extremely side angle, which is great. That is not only that, the brightness of images also looks very consistent from extremely wide angle. At certain angle, around 30 degrees off center for the LG C2 and around 50 degrees off center for the LG B2, color of images may still shift. However, images remains still looks accurate from wide angle. This is suitable for you who have a wide seating arrangement for watching TV or often watch a big game with a group of friend or family.

Motion Handling

The other great point offered by OLED TVs including the LG B2 and C2 is about their nearly instant pixel response time. With around 2.5 ms of pixel response time, this makes fast motion looks very clear with almost no blur trail following fast moving object. But on the other hand, the near instant pixel response time can cause low frame rate content like 24p movies appears to stutter. Fortunately, this issue can be reduced by interpolating them to higher frame rate or enabling their BFI (Black Frame Insertion) mode.

Unlike LED TV that use PWM dimming system to dim their backlight, both don’t use PWM since they don’t have backlight. This makes their screen is almost flicker-free, which is great. However, a flickering that match to the frame rate of content is required to reduce persistence blur. And for this purpose, both have an optional BFI mode that make their screen flicker. A bit unfortunately, both only support 60 Hz BFI mode that means they can flicker at 60 Hz only, even if they are playing 120 Hz content. This is strange considering in last year, all models of LG’s OLED TV support both 60 Hz and 120 Hz BFI. So, for 60 fps content, it is great. But for 120 Hz content, this precisely can cause some duplications. So, this will be disappointing if you want to play 120 Hz games and want to use this feature.

Both have native 120 Hz refresh rate panel that means they can play any 120 Hz content properly, which is great. The great thing is that they also support VRR (Variable Refresh Rate) panel. No matter the resolution of the source, their VRR technology is able to range between 20 Hz and 120 Hz, depending on the content. Furthermore, their VRR technology is also compatible with FreeSync, GSync, and HDMI Forum VRR. So, whether you play game with PS5 or Xbox X Series, a PC with Nvidia or Radeon Graphic card, they work well with them. As we have known, VRR technology can improve their gaming experience by reducing screen tearing.

Winner: Draw

Inputs

As their main connectivity, both of the LG B2 and C2 are equipped with 4 HDMI ports. All of their HDMI ports supports most of HDMI features like HDCP 2.2., CEC, ALLM, and HDMI 2.0 full bandwidth. Additionally, one of their HDMI ports also can be used as HDMI ARC and the great thing is that it also supports eARC. This allows them can pass high quality audio formats like Dolby Atmos via True HD. Sadly, although their HDMI ARC supports eARC, but they don’t support any DTS formats. The other great point is that all of their HDMI ports support HDMI 2.1, allowing them support HFR content like 4K @ 120 Hz. This allows you to play high quality games supported by latest model of game console like PS 5 or Xbox X Series.

Besides their HDMI ports have great ability, their input lags in Game mode is also.  No matter the resolution, with 60 fps games, input lag of the LG B2 is about 12 ms while input lag of the LG C2 is about 10 ms. With 120 fps games, their input lag is much lower and almost similar, which is about 6 ms for both. Ignoring their difference, their input lags is low enough to make them very responsive for any games. Your act on your game pads will be in sync with what you see on their screen, which will please most gamers.

LG B2 vs LG C2 Performance

Movies

The LG B2 and C2 OLED are great TVs when used for watching movies in a dark room. Both have outstanding dark room performance. Dark scenes of images have a lot of details and without “crushed black” thanks to their infinite contrast ratio, nearly perfect black uniformity, and pixel dimming level. Additionally, small bright object can also be shown perfectly without any blooming around it.  Besides they have good performance in a dark room that offer you watch movies with cinematic experience, both also have great picture quality overall. They have excellent 4K up-scaling engine that allows you to watch your old collection movies in 4K resolution. Their instant response time and BFI feature makes fast action movies looks very smooth on their screen. Both of the LG B2 and C2 can handle 24p judder well. So, no matter the source, both can show them with judder-free.

However, this doesn’t mean they don’t have shortcoming. As we have mentioned, their instant response time makes low frame rate content appears to stutter. And since most movies have frame rate of 24 fps, this certainly also makes movies can appear to stutter. Interpolating them to higher frame rate or enabling their BFI mode may can reduce images stuttering, but this cannot be removed completely. But overall, their performance is still great overall.

Winner: Draw

Sports

When used for watching sports, their performance is also equally great. Both have good SDR peak brightness and great reflection handling, allowing you to watch sports in most bright rooms without distracting by the glare and reflections. That is not only that, their excellent motion handling and BFI mode also makes fast sports looks very smooth on their screen. If you watch sport with large surface with same color like hockey or baseball, the field looks very good without a lot of dirty screen effect. And if you watch a big game with a group of your friend or family, all of you will get the same picture quality, even for you who sit on the side.

Sadly, although both have good SDR peak brightness, but their ABL is very aggressive, so large bright scene will look dimmer. This means, you will get brightness fluctuations in some sports. But this actually is not very distracting since most of content rare show the entire screen is bright.

Winner: Draw

Video Games

Performance of the LG B2 and C2 when used for playing games will please most gamers. Besides they have excellent picture quality and great motion handling that makes images of games looks well and smooth on their screen, both are also very responsive for any games thanks to their low input lags. That is not only that, they are also supported by some advanced features that will improve your gaming experience. The VRR technology allows you to play any games with screen tearing free. Additionally, since their VRR technology is compatible with FreeSync, GSync, and HDMI Forum, their VRR can work well with most modern games console. The support of HDMI 2.1 also allows you to play high quality games supported by a modern game console like PS5 or Xbox X Series.

However, as we have known, the OLED Panel is susceptible to permanent burn-in, especially when they are displaying a static image over long time. So, playing the same games for long time should be avoided to reduce the risk of permanent burn-in. Overall, both are great TVs for video games. However, the LG C2 is a bit better thanks to it’s a bit lower input lag.

Winner: LG C2

HDR Performance

Both of the LG C2 and B2 support the same HDR format, which are HDR10, HLG, and Dolby Vision. This gives you a flexibility to watch HDR content in different format. And overall, their HDR performance is great, especially when showing shadow details. Thanks to their infinite contrast ratio, perfect black uniformity, and pixel dimming level, shadow of HDR images looks outstanding with a lot of fine details and there is almost no noticeable “crushed black”. In essence, shadow details of HDR images can be shown as expected in HDR.

Meanwhile, in color reproduction, their performance is also great, especially for most current HDR like HDR10 content. As we have discussed above, their color coverage in DCI P3 is nearly perfect. And since most current HDR like HDR10 content is mastered in DCI P3 color space, of course, they looks very vivid and life-like on their screen. Sadly, both cannot show bright saturated colors, so very bright scene may be shown less accurate. Additionally, both also only have decent color coverage in Rec.2020 where next-gen HDR format like Dolby Vision are mastered. This means, besides very bright colors, some certain colors of Dolby Vision content may look inaccurate.

Meanwhile, the advantage of the LG C2 over the LG B2 is about their color gradient thanks to its upgrade images processor. As we have discussed, color gradient of LG B2 is only decent. So, there is still noticeable banding when they are showing HDR content. On the other hand, there may be still some little banding on the screen of the LG C2, but it less noticeable than on the screen of the LG B2.

The other advantage of the LG C2 is about its HDR peak brightness thanks to the evo OLED technology. With HDR content, the LG C2 can show small highlight at around 800 nits. This may be less bright than 1000 nits what intended by content creator for cinematic HDR experience. But small highlight still pop the way they should in HDR. On the other hand, the LG B2 can only show small highlight at about 700 nits. This may be not as bright as the LG C2, but it is still bright enough to make small highlight look standout on its screen.

Overall, the LG B2 and C2 have great HDR performance. However, the LG C2 is better thanks to its better color gradient and brighter HDR peak brightness.

Winner: LG C2

Conclusion

As we have discussed above, except its 42 inches and 48 inches variant, the LG C2 has used evo OLED panel found the LG G1 in last year or LG G2 in this year. This really deliver brighter images than standard OLED panel of the LG B2. Additionally, the use of Alpha 9 Gen 5 processor also makes performance of the LG C2 is better than the LG B2 that use Alpha 7 Gen 5 in some features. Nevertheless, overall, both are great TVs for mixed usage. Although not as good as the step-up model C2 OLED, performance of the LG B2 is also not far behind the C2 OLED. So, ignoring the superiority of the LG C2, whether you use them for watching movies, sport, TV Shows, HDR content, or playing games, you will be satisfied with their performance and picture quality.

So, which is a better choice among them? If you want small screen TV, there is no option for you since the 42 inches and 48 inches variant are only available on LG C2. Meanwhile, for larger screen, especially 55 inches, 65 inches, and 77 inches where these screen sizes are available on both, the decision certainly comes back to you according to your own preference. The LG C2 may be better overall, but with the same screen sizes, it is sold more expensive than the LG B2.
