There’s nothing worse than straining to watch a show or movie because the screen is smudged or covered in dust. If you don’t clean your TV occasionally, dust and fingerprint smudges can build up. Periodically clean your TV so it keeps looking brand new and you can keep seeing the picture clearly.

Important: Never use any type of window cleaner, soap, scouring powder, wax, or any cleanser with solvents such as alcohol, benzene, ammonia, or paint thinner. Never use abrasive pads or paper towels. If you do, you can scratch the screen or strip the anti-glare coating off the screen and cause permanent damage. Never spray water directly onto the TV. Make sure to wipe the TV as gently as possible. TV screens are fragile and can be damaged when pressed too hard.
- Turn the TV off and let it cool down for a few minutes before unplugging it.
- To clean the frame and screen, gently wipe it with a microfiber cleaning cloth. Make sure to wipe the TV frame and screen as gently as possible. TV screens are fragile and can be damaged when pressed too hard.
- If you don’t see results, spray water directly on to your microfiber cleaning cloth and gently wipe the frame and screen.
- Let the TV dry completely before you plug the TV back in.
1. What does “4K” mean, what does “Ultra HD” mean, and what are the differences between the two?
Quite simply 4K is used to refer to a resolution which amounts to about four times the pixel count of Full HD resolution. Full HD is measured at 1920 x 1080 pixels and for most consumer purposes, 4K UHD resolution is set at 3840 x 2160 pixels, which is roughly 4 times as many pixels as FHD (Full HD). They’re also colloquially called 2160p and 1080p resolutions respectively. There is also a less common 4K resolution called DCI 4K, rarely found in 4K TVs but common in 4K home theater projectors and some 4K video cameras. This is set at 4096 x 2160 pixels and offers roughly half a million pixels more than 4K UHD.
As for ultra HD, it has a more flexible meaning. Right now it’s practically synonymous with 4K UHD TV displays and other 4K consumer products but when other resolutions like 6Kand 8K become more common, they could also be called ultra HD.
2. Why are 4K screens/displays preferred over 1080P
what are the advantages and why is this technology worth it? How does this ultra-high definition technology change the user experience for the better on various devices (TVs, computer monitors, phones and cameras)?
4K resolution isn’t actually easy to distinguish from normal FHD on smaller display devices of less than 45 inches across (diagonally) unless you get really close up to the screen but aside from this 4K definitely brings with it a much better level of sharpness on all larger screens and even on smaller screens, the sharpness and smoothness of digital video looks far superior when viewed close up. Aside from these obvious benefits, 4K display devices come with the best peripheral display technologies these days and 4K recording devices are obviously better because their 2160p video output is more future-proof for being displayed on larger screens (which are becoming more popular among consumers).
3. What are the current 4K screen technologies available to consumers (e.g., HDR, OLED, AMOLED, Quantum Dot [QD], UHD, etc.)? Please describe the differences between these technologies mentioned and list any others that I failed to mention.
The most important 4K display technologies (mainly for 4K TVs) currently available are HDR and OLED. Quantum Dots and other brand-specific technologies mostly revolve around enhancing 4K resolution or HDR in any case. OLED is its own distinct display technology for display design and it is also found in non-4K screens.
4. Where can consumers currently get/watch 4K content (e.g., streaming sites, 4K UHD Blu-ray players, etc.)? Why isn’t broadcast TV in 4K yet, and when is this coming?
The best and most easily accessible sources of 4K content for anyone anywhere in the world are 4K UHD Blu-ray discs. You’ll need a 4K Blu-ray player to play them but if you get one, you can watch any of the dozens of 4K movies now coming to Blu-ray on your 4K TV even if you have no other source of 4K content or the right internet connectivity to access streaming media apps. After 4K Blu-ray, the most easily accessible content in 4K is the stuff available from streaming internet services like Vudu, Amazon Prime, Netflix, YouTube, Hulu and others and apps for all of these are found on most 4K TVs right out of the box. However you’ll needs at least 20Mbps of connectivity to your home in order to stream 4K video from said app
