UHD stands for ultra high definition, and is also referred to as 4K, pertains to resolution. In other words, how clear and sharp images are. QLED stands for quantum light-emitting diode, which is a term for TVs in regards to color technology. More specifically, a QLED TV is one that uses Quantum Dot by Samsung.
Resolution, color, video processing and other image quality factors are basically the same. Most QLED and OLED have the same resolution and 4K, and both can achieve 8K resolution too. Neither technology has major inherent advantages in color or video processing, although QD-OLED could deliver improved color.
QLED TVs are almost all UHD. As a newer technology, QLED is utilized in 4k resolutions and higher which happens to qualify them as UHD displays. UHD, or ultra high definition, refers to the resolution of a display being 4k (3,840 x 2,160 pixels) or higher resolution. QLED and UHD are not competing terms.
In looking at standard 4K LED TVs vs 4K OLED TVs, both offer great viewing experiences and improvements over 1080p. But LG OLED technology will truly transform your home entertainment experience with superior blacks, cinematic colors and High Dynamic Range with Dolby Vision support.
In terms of picture quality, OLED TVs are generally considered to be the better option due to their perfect blacks and infinite contrast. However, QLED TVs can still produce very high levels of brightness and colour accuracy, and they are often more affordable than OLED TVs.
The Quantum Dots that make up the QLED panels are capable of emitting not only brighter and sharper images but darker ones for low-lit scenes. QLED displays outperform both LCD and LED displays in terms of color reproduction and, naturally, the images offer a superior contrast ratio.
If you prefer a brighter picture, Samsung's QLED sets are the way to go. However, if you want a better contrast ratio (where blacks look black and not gray) and a wider viewing angle, we recommend an OLED TV from LG.
Is LG better than Samsung in TV? When it comes to Samsung TV vs LG TV, QLED TVs from Samsung is the superior of the two brands. Along with this, for people who are looking for an enhanced contrast ratio and a wider viewing angle, LG OLED TVs are a good way to go.
While OLED TVs are known for their exceptional contrast, QLED TVs excel at peak brightness. Most up-to-date QLED and OLED displays offer Ultra High Definition (UHD) resolution. QLED enables higher brightness in addition to increased longevity because it is resistant to burn-ins.
Samsung vs LG
Samsung TVs usually get a fair bit brighter and have better contrast, while LG TVs generally have much wider viewing angles and better smart features. While LG has more OLEDs in its lineup, Samsung has released its own OLED TVs known as QD-OLED, which produce brighter colors than LG's OLEDs.
Although there are plenty of quality TV and computer monitor screens out there, UHD 4K and 4K HDR lead the pack. Of the two, 4K HDR is a better option because it boasts a high pixel count and the ability to adjust the colors and contrast automatically, giving you a next-level viewing experience.
A 4K TV comes equipped with this same resolution—roughly four times the resolution of the previous 1080 standard—whereas UHD offers a display resolution of 3,840 x 2,160. While this is slightly short of "true" 4K, UHD resolution is often rounded-up and referred to as 4K for the sake of simplicity.
Buy an OLED TV if:
You want the best possible picture quality, regardless of price: OLED TVs produce the best HDR picture quality, the best motion, and the widest viewing angles of any TV currently available. Learn more about OLED technology in this article.
Sony vs Samsung
Samsung TVs have a picture quality comparable to Sony TVs, and in general, they're pretty competitive with each other. A big difference is that Samsung has better gaming performance, but if you don't need that, either brand is a good choice.
With an increasing number of pixels are displayed, most Full HD smart TV allows you to enjoy better colors and clarity and more lifelike images on the screen. On the other hand, 4K TVs have four times more pixels than Full HD smart TVs. 4K refers to a horizontal resolution of 4,096 pixels.
The results are dramatic, and OLED TVs have topped our “Best TV” lists for several years. For the best example of the best display technology, we recommend the LG C2 (available at Amazon for $1,296.99) . This LG is not only the best OLED TV of 2023, it's our current pick for the best TV, period.
Is OLED TV worth buying? OLED TVs have the best picture quality, best viewing angles, infinite contrast ratios, true blacks, and—on some models—very thin profiles. So, while OLED TVs aren't as bright as LED or QLED TVs, and are more expensive than both, they're well worth the investment.
Samsung and LG are well-regarded for producing high-quality smart TVs. As a result, there is no clear winner as to which is best. With that said, there are some key differences between the two that may make one brand better than the other depending on what you are looking for in a television.
The lifespan of OLED TVs is a common concern among consumers, but the technology has proven to be reliable and durable. OLED TVs are known to have a lifespan of around 100,000 hours, which is equivalent to over a decade of use (with an average of 8-10 hours of watching hours daily).

Drawbacks or disadvantages of QLED
➨QLED based TVs suffer from "light bleed" effect. This effect is visible in certain scenes. It results into slight haze around bright objects which blurs lines which should be usually sharp. ➨With QLED based display screens, best viewing angle is dead center.
It's also worth mentioning a newer technology called QD-OLED TVs. This combines the best of both worlds, using a blue OLED panel with a quantum dot filter to create brighter primary colors. The result is a screen that has better color saturation (around 200% of traditional LED-LCD TVs) and better off-axis viewing.
QLED TVs have better color accuracy, contrast, and brightness, resulting in altogether better picture quality. QLED is often more expensive than LED and consumes more energy. LEDs are made by every major TV manufacturer, while QLED is Samsung's exclusive technology. LED TVs offer a wider viewing angle than QLED TVs.
The lifespan of a Samsung TV is roughly 4 to 8 years.
In addition, it may last longer if you don't use it much or when the picture is not turned to maximum brightness during screen time. Also, proper maintenance is another factor that is going to affect the longevity of your Samsung TV.
