OLED TV- What is it and How Does it Work?

The Signature OLED RX is a 65-inch 4K TV that rolls up and disappears into its base. It also has a line view setting that peeks the TV out for use as a clock or to show photos.

In 1997, the FDA allowed pharmaceutical companies to advertise prescription drugs directly to consumers in TV ads. This opened the floodgates to the side effect-filled commercials we see on television today.

ARC is short for Audio Return Channel and allows the TV to send audio back to your AV system via an HDMI cable (it only works with compatible gear of course). In a way it’s like a normal headphone jack but far better as it removes the need for extra cables, reduces audio loss over long distances and supports object-based surround such as Dolby Atmos.

The TV RX is LG’s first 8K tv which means it has some pretty impressive specifications. For example it has 4K upscaling for HD content and an array of AI features that improve image quality and help with things such as noise reduction. It also has an innovative brushed aluminium base that lets you engrave a message and it can act as a smart speaker with Amazon Alexa and Google Assistant built in.

It’s a premium TV that comes in both flat and curved models. Both support Dolby Atmos for immersive audio and have full HDR to give a great picture. This model uses a unique panel design that LG calls Signature OLED and it can display a wide colour range for excellent colour accuracy.

Variable refresh rate support (VRR)
Many games support VRR, which is a variable frame rate that the TV matches with the game to reduce the number of dropped frames and stuttering you might otherwise experience. This feature only works when the TV and game both support it and it’s most important for gamers. It’s important to check that your TV supports VRR and that your graphics card or console supports it too.

Composite / RCA inputs
If you have an older TV then it might have a composite or RCA connection which is useful for connecting things like DVD players or early satellite receivers. This is an analogue only connection so it can’t support High Definition video connections and requires separate audio cables for sound.

S-Video input
S-video is an improvement on component video and is a single yellow phono connector that can carry both Luminance and Chrominance in two separate streams which helps improve picture quality. However it’s not compatible with audio so you’ll still need to use separate cables for that.

USB input
Most newer TV’s will have a USB connection which can be used to connect a flash drive and view photos or play music from a USB stick. Some TV’s can even connect to a USB hard drive for PVR functions (recording shows) which is really handy.

The ethernet input on modern Oled tv rx is often used to connect to your wireless network for access to online content. It’s also sometimes used for diagnostic purposes like updating the TV’s firmware or running a remote control diagnostic. It’s not something you’ll need for most day to day usage though.

LG TV RX – What You Need to Know

LG’s groundbreaking rollable TV RX has different capabilities in each of its view states. In full view the screen rolls out for viewing while in line view it minimizes with useful information like weather and time. In zero view the TV can act as an advanced AI smart speaker.

Lou says the FDA’s rules say drug ads must include the major risks of a medication and sources where consumers can find prescribing information, such as a doctor or a toll-free telephone number.

ARC, short for Audio Return Channel, is a feature first introduced in HDMI version 1.4 back in 2009. It lets your TV send audio data to a compatible soundbar or AV receiver over the same cable used to carry video. That eliminates the need for a separate optical audio connector and makes a tidy, simplified setup possible. You’ll still need a high-speed HDMI cable with ARC support (check the manual for model-specific details).

The other big advantage is that ARC supports two-way audio flow, meaning that your TV can send the music and dialogue from its own built-in apps and streaming services back to itself over the same cable. This means you can control your media player’s volume using your TV remote, which is a big convenience.

A limitation of the original ARC specification is that it doesn’t allow 5.1 audio to pass through, even when your TV is set up in a surround-sound configuration and you’re playing a movie with a Dolby Digital or DTS soundtrack. This was a big frustration and helped lead to the development of eARC, which fixes this issue.

For most buyers, ARC is going to be the most important thing they’re looking for. It’s the fastest and easiest way to get up and running with a new TV, eliminating the need for a separate optical audio cable that might otherwise be needed to connect your media players.

It’s also the only way to use your TV to control your AV system, and this can be a real timesaver if you’re constantly juggling inputs between a set-top box, games console or Blu-ray player and your home theater setup. You’ll need to enable TV Audio Output on the AV receiver or soundbar, and make sure your devices are set up as outputs rather than inputs, but that’s pretty easy to do with most modern systems.

ARC isn’t just a nice convenience, it actually improves the audio quality over older standards like TOSLINK. The ARC protocol gives you more than double the bandwidth that TOSLINK could ever manage, and that extra room makes all the difference when it comes to clarity and detail.

ARC is available on all of the TVs we’ve reviewed here at FlatpanelsHD and most soundbars too, from the Devialet Dione to the Sonos Arc and beyond. ARC is included in every one of our top 10 best TVs for 2019, so it’s very likely that any TV or soundbar you buy today will have this capability. That said, you should always be wary of buying an old TV with this functionality disabled or, worse yet, a TV that doesn’t have it at all. It just isn’t worth the hassle.
