What people are saying

Rated 5 out of 5 by from Excellent HD Picture This was a excellent buy. I really love the HD picture. It’s seems the picture is better now than the first day I bought it. I have bought 3 other LG TVs since this 79ub9800 purchase.

Rated 3 out of 5 by from Good Sound, but Menu is lacking The remote has buttons that arn't even used. You have to drill 3 to 4 layers down just to get to where you can change the output from the built in speakers to other out put options. Something like that should be on the remote.

Rated 5 out of 5 by from A totally immersive presence in the room The equipment is an engineering marvel, but the picture is unbelievable. Deep rich blacks and brilliant vibrant colors captivate you. It dominates the room, you can't take your eyes off of it.

I have a 79UB9800. What are the improvements if I go to 83in LG C1 OLED?

Asked by: angelom
The LG 79'' Class (78.5'' Diagonal) 2160p Smart w/ webOS 3D Ultra HD 4K TV,Model # 79UB9800 is a 2014 model while the LG C1 83 inch Class 4K Smart OLED TV w/AI ThinQ® (82.5'' Diag), Model # OLED83C1PUA is a 2021 model so the technology in the 2021 OLED83C1PUA is much more advanced than the technology employed in the 2014 79UB9800. The 79UB9800 is an LED LCD TV and the OLED83C1PUA is an OLED TV. OLED TVs are more like Plasma TVs.They’re thin, light, and offer incredible contrast and color that’s second to none. When OLED TVs first arrived in 2013, they were lauded for their perfect black levels and excellent color, but they took a bit of a hit due to brightness levels that couldn’t compete with LED TVs, however, current OLED TVs are much brighter than they used to be. LED TVs use LEDs as their source of backlighting. Thus, when you see the term “LED TV,” it simply refers to an LED-backlit LCD TV. The “OLED” in OLED TV stands for “organic light-emitting diode.” OLEDs have the unusual property of being able to produce both light and color from a single diode when they’re fed electricity. Because of this, OLED TVs don’t need a separate backlight. Each pixel you see is a self-contained source of color and light. The biggest benefit of OLED screens when compared to LED TVs is that each individual pixel receives its own luminance and power (as opposed to LED TVs, which have persistent pixels that require an external source of light to see). When it’s on, you can see it. When it’s off, it emits no light at all — it’s completely black. As a result, OLED TVs produce deeper blacks allowing for higher contrast and richer and when it comes to black levels, OLED reigns as the undisputed champion. LED TVs rely on LED backlights shining behind an LCD panel. Even with advanced dimming technology, which selectively dims LEDs that don’t need to be on at full blast, LED TVs have historically struggled to produce dark blacks and can suffer from an effect called “light bleed,” where lighter sections of the screen create a haze or bloom in adjacent darker areas. OLED TVs suffer from none of the black-level problems of traditional LED TVs. If an OLED pixel isn’t getting electricity, it doesn’t produce any light and is, therefore, totally black. When it comes to brightness, LED TVs have a considerable advantage. Their backlights can be made from large and powerful LEDs. OLED TVs can get pretty bright, too, and with such dark black levels, they have a high contrast between the brightest and darkest spots on the screen, however, it’s important to note that all modern TVs — whether OLED, LED, or QLED — produce more than adequate brightness. The consideration then becomes where the TV will be used. In a dark room, an OLED TV is going to perform best, and while LED TVs will outshine them (quite literally) in more brightly lit environments, there have been big gains recently in OLED brightness, making them perfectly suitable for nearly any situation, save direct sunlight beaming onto the screen. Response time refers to the time it takes for each individual pixel to change states. A pixel’s state is not only its color but also its brightness. With a faster response time, you get less motion blur and fewer artifacts (source material notwithstanding). Because OLED pixels combine the light source and the color in a single diode, they can change states incredibly fast. By contrast, LED TVs use LEDs to produce brightness and tiny LCD “shutters” to create color. While the LED’s brightness can be changed in an instant, LCD shutters are by their nature slower to respond to state changes. OLED currently offers the fastest response time of any TV technology in use today. OLED can achieve refresh rates of up to 1,000 times higher than LED TVs. With LED TVs, the best viewing angle is dead center, and the picture quality diminishes in both color and contrast the further you move to either side. OLED TVs can be viewed with no luminance degradation at drastic viewing angles. OLED panels require no backlight, and each individual pixel is extremely energy-efficient. LED TVs need a backlight to produce brightness. Since LEDs are less energy-efficient than OLEDs, and their light must pass through the LCD shutters before it reaches your eyes, these panels must consume more power for the same level of brightness. OLED panels require no backlight, and each individual pixel is extremely energy-efficient. LED TVs need a backlight to produce brightness. Since LEDs are less energy-efficient than OLEDs, and their light must pass through the LCD shutters before it reaches your eyes, these panels must consume more power for the same level of brightness. OLED is also lighter and thinner, uses less energy, offers the best viewing angle by far and is the superior TV technology today...^Ivan The OLED83C1PUA

What is wall mounting system of 79' smart 3D tV

Asked by: Kaps
If the model number for the LG 79" Class (78.5" Diagonal) 2160p Smart w/ webOS 3D Ultra HD 4K TV, Model # 79UB9800 is the correct model number for the TV that you are inquiring about, LG has an optional Wall mount bracket Model # LSW640B that is compatible with this TV. The TV is also a VESA compatible TV so any VESA compatible Wall Mount that has the same Wall Mount A x B Pattern of 600 x 400 will work although we recommend that you use an LG brand wall mount. When you do not use LG’s wall mount bracket, please use a wall mount bracket where the device is adequately secured to the wall with enough space to allow connectivity to external devices. If you choose to use an optional Wall Mount, consult with your local dealer for a wall mount that supports the VESA standard used by your TV model...^IFV
