Up until recently LCD TVs were dominating the market. Being around for many many years manufacturers have improved the technology and production problems to a point were each year now we get small improvements over the last. But no matter how many years will pass Liquid Crystal Displays as their full name is will always have some big weaknesses that derive from the technology that is used. And the most obvious one is black colors. Manufacturers have dramatically improved this over the years but they never could achieve true black colors. And this is where OLED came in. With OLED technology TV manufacturers were able to achieve what was impossible up until now with the classic LCD panels. True black colors. Although Panasonic and Sony are slowly jumping on the OLED bandwagon LG was one of the first to fully support this new technology. So now we are at a point that OLED TVs have become mainstream although their price is still a bit on the high side compared to classic LCD TVs. Today we will be looking at a 2017 model in this LG OLED55B7V review.


The LG OLED55B7V is a 55″ OLED 4K UHD TV. Being and OLED means that there is no need for backlights and this makes these TVs unbelievable thin. I really like how thin it looks and it makes a great looker in any room you want to place it either on a furniture or on the wall. The OLED panel is surrounded by a thin metallic silver trim which extends to the black bezel. The bottom part of the TV is a bit more thick considering this is where all the connections and hardware is housed as well as the speakers. The TV is placed on a metallic crescent stand with the LG OLED engraved on it. The US model with number OLED55B7A comes with a little different stand design that shows on the pictures below without changing anything else on the general design or characteristics of the TV.

Video Quality

The advantage of OLED technology can be seen immediately from the first viewing. The advantage of being able to switch on and off each and every pixel of the TV individually is very clear compared to other technologies. This way you get absolute blacks and you do so without nearby bright elements affecting any part of the screen. Peak brightness is still the biggest weakness of OLED technology and although we are still away from the theoretical 1000 nits that LG claims things are better than last year’s models showing that improvements are made each year as the technology matures. When you get so true blacks the colors pop out of the screen with stunning vibrancy and realism. OLED always struggled to find some balance between unbelievable true blacks and clean visible shadows and in this regard things seem to have improved a bit this year also. Viewing angles are also a strong point of OLED technology due to the self emitting nature of it’s pixels making them ideal in big rooms with different viewing positions without loss in contrast or saturation.

As far as HDR we get a lot of different options with the TV being able to handle HDR10 which is the open standard used in 4K UHD disks, HLG (Hybrid Log-Gamma) which is the HDR that is used for broadcasting in Europe, Dolby Vision which is the proprietary HDR technology by Dolby that is using dynamic metadata for scene by scene optimization and Technicolor’s Advanced HDR which is still a format that has not yet become very known to most.

The LG OLED55B7V has proved to be very good for gaming also with a very low input lag measured at around 21ms if you use the Game mode in either 1080p resolution or 4K with HDR. Many people are worried for image retention and the reality is that this is a problem even with premium models. My experience has shown that this depends on a lot of factors and sometimes you need to be lucky to get a good unit because even if you are extra careful you can still get this problem with any TV nowadays. Fortunately I didn’t have any image retention with the LG OLED55B7V but you should always be careful not to leave any image frozen for a long time that could potentially create this problem.


All the inputs are on the body of the TV compared to other brands that prefer to use a separate box that houses all the connectors. To tell you the truth I prefer to have everything separately because it gives more freedom as to how and where to place all cables instead of having all of them hanging on the back of the TV but i guess this is a personal taste without affecting the performance in any way.

What we get here is 4 HDMI 2.0b ports that are HDCP 2.2 compliant enough to connect all devices you would need if you don’t use an A/V receiver with a lot of HDMI inputs. We also get 3 USB ports one of which is version 3.0 something very useful when it comes to big files that need fast transfer rates. We also get a typical RJ-45 Ethernet port if you prefer wired connection to the internet, an optical digital out port, terrestrial and satellite inputs as well as a common interface port and lastly a headphones port. All in all i would say we get everything you would expect and need from a TV like this.

OS, Apps and Features

As with all LG TVs for 2017 this model is using the WebOS 3.5 platform which is user friendly and very responsive without any major delays in comparison with other TVs that use Android. The platform offers a wide range of applications laid like cards that can be arranged in any way you prefer.

The remote control has a great design also combining the motion sensing pointer with a full suite of buttons. You can also find dedicated buttons for Netflix and Amazon but you can also program shortcuts for other applications to use with any number on the remote you want. The buttons are spaced out making them easy to press without pushing the wrong button accidentally.

For such a thin TV we get pretty good sound quality for casual viewing with clear speech and adequate dynamic range. The down firing speakers don’t help a lot to make the sound stretch far into the room so I would suggest a separate sound system if you are serious with your viewing pleasure.

Final Thoughts

The LG OLED55B7V is really a great TV that you can find in either 55″ or 65″ variants. OLED has come a long way and as it is right now the picture quality is truly stunning deserving a viewing to really appreciate what it has to offer. You may not get the brightness of LED LCD TVs but each year OLED is improving on this while on the other hand LCD TVs will never have the spectacular blacks you get now with OLED. One real downside of course is the price that is still on the high side even compared to the top tier LCD TVs. If you have the budget then by all means go for it but if your budget is something you have to consider then you may want to think twice if it really is worth it to pay extra money. Highly recommended.

  1. Very informative. I am a huge fan of LG TV’s, but they tend to be a bit more pricey than the other brands. I love the design of this unit, but what has helped me decide on this is the 4 HDMI inputs. Most TVs only offer 3, but with a game console, cable, Apple TV, and a 3D blu-ray player, I would much rather find a TV with enough ports rather than buying an expansion unit. Thanks for sharing this!

    • If 4 HDMI ports is what you need then this TV has enough for you. Overall this is a spectacular TV and you will not go wrong with it if you decide to buy it.

  2. That is a beautiful TV! The price is pretty high still. When you do think they’ll start to come down on the price? I know with technology there’s always a period where the price is inflated and then it drops rapidly at some point. How many years out are we, do you think?

    • Hello Christina. Price will definitely go down over the years and as new technologies come out but in my opinion as both OLED and LCD TVs will coexist OLED will always be a bit higher in price than anything else unless some other new TV technology come out to replace it. This happens because OLED is a more expensive technology to produce unfortunately. I think it will be another 3-4 years before we see any considerable price reduction to make even the smaller OLED models affordable.

  3. Stratos,
    I have an 2 year old model LG 65 inch LED tv mounted on the wall. I love the picture and sound is OK for the room it is in. I am very happy with this purchase. The USB and HDMI ports are pointed to the side, I can plug into it without my fingers trying to find a plug in port. This makes for easy video file uploads and views.
    Do you think the upgrade to a OLED system would be worth the money. I do not play games on it, I have a blue ray player hooked up to it for watching movies.

    • Hey John. I have seen both LED LCD and OLED TVs side by side and i tell you for sure the difference is unbelievable. For me it is worth it but it depends on a lot of things. Your TV is not that old but if you are considering an upgrade this TV is definitely one to look for. The quality upgrade over an LED LCD is big.

  4. I have been in the market for a new television and agree that LED’s are often very dark. It looks like LG has solved this problem with the OLED TV.

    While the many pictures you display here demonstrating the quality of the picture, I particularly like the kids with the flashlight illuminating the bicycle.

    When you head over to your recommendation on where to buy (Amazon), I see that the 65 inch is also reasonably priced for the quality. Thanks for the review.

    • Hello there. Yes OLED sometimes can have some problems display scenes darker than what they really are but in general the picture quality is absolutely stunning compared to LED LCD TVs. If you consider buying a new TV and you have the budget i would definitely recommend an OLED.
