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 and more vibrant colors than LG's OLEDs.
While little to choose between Samsung TV and LG TV in terms of raw quality, you should consider the supported formats. While LG supports Dolby Vision on its high-end TVs, Samsung TVs choose HDR10+ instead. LG has the advantage here, as Dolby Vision has a 12-bit color gamut versus HDR10+'s 10-bit.
Samsung's Crystal UHD TVs not only display 4K content accurately but also offer additional features that enhance the viewing experience. When considering factors such as image quality, HDR support, and smart features, Samsung's Crystal UHD range provides a more well-rounded experience in comparison to LG's UHD range.
Samsung's Quantum Dot technology adds a thin layer of nanocrystals to the screen, while LG's WOLED technology adds a beam of white light. Both are intended to improve picture quality, but the Samsung OLED ends up looking ever so slightly brighter (read: better) than LG OLED.
You prefer better contrast and blacker blacks
With LG being the top manufacturer of OLED TV panels worldwide while Samsung Display dominates QLED panels for TVs, the LG TVs versus Samsung TVs debate can easily turn into an OLED vs QLED question.
OLED has better contrast and black level
QLED/LCD TVs, even the best ones with the most effective full-array local dimming, let some light through, leading to more washed-out, grayer black levels and blooming around bright sections.
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.
Truth be known, buying a 4K TV versus a UHD TV will not make much of a difference to the average viewer, with both offering excellent resolution. However, if having the highest possible picture clarity is essential to you, you'll want to look for a 4K unit that displays at 4,096 x 2,160.
OLED has a significantly wider and better viewing angle when compared to 4k UHD LED TVs. Unlike LEDs that still have shutter issues because of screen pixels, OLED comes with advanced pixels powered by self-illumination capabilities. Thus, OLED is a clear winner in this department.
In this respect, Full HD smart TV offers only 32 degrees, whereas 4K gives four times much more resolution. With 4K, you feel more extensive coverage and enjoy the smoother immersive experience. As mentioned above, a 4K smart TV might be a better choice than a Full HD smart TV.
Their LED models consistently have great viewing angles, but that comes at the cost of having mediocre picture quality in a dark room, quite the opposite of their OLED offerings. Luckily, all their smart TVs come with the user-friendly webOS platform built-in, making it easy to watch your favorite content.
As said earlier, QLED technology is just an improvement of LED TVs. It doesn't provide a completely different way of emitting light or producing images. Instead, it boosts the TV's brightness and color accuracy.
But as long as you have the right internet speed to use 4K technology, there's no reason to avoid 4K TVs. That said, it's not worth paying extra until more 4K content is available. The good news is that 4K TVs are becoming more reasonably priced.
Full HD is just another term for 1080p or 1920x1080, and those are all ways of referring to the same resolution. By contrast, 4K has a resolution of 3840x2160. That's a lot more pixels in the overall image — totaling over 8 million pixels. As always, the higher the resolution, the sharper the picture will be.
Ultra-High Definition (UHD) refers to displays capable of displaying images with at least 3840 by 2160 pixels resolution. This is 4 times the total number of pixels available in FHD. 4K is the term used for UHD displays that can display images with a resolution between 3840 by 2160 pixels up to 4096 by 3112 pixels.
In terms of sheer pedigree, LG comes out as the better brand. As we've said, its OLED televisions are among the very best commercially available sets out there – and on top of that, the webOS smart platform has the stronger reputation.
LG TVs are manufactured by LG Electronics, with help from their manufacturing affiliate, LG Display which manufactures the LCD panels, OLED displays, and flexible displays, for different screen sizes.
LG TVs are designed to last up to 100,000 hours or more, meaning at least a decade of normal use. This is on par with LED TVs from almost every other brand. So, there's no competitive advantage there.
In terms of picture quality, OLED TVs are generally considered to be the better option due to their perfect blacks and infinite contrast.
The optimal choice will rely on your specific requirements. For instance, OLED is the way to go if picture quality is your top priority, but QLED is the better option if you are on a tighter budget. Typically, QLED and OLED TVs are Ultra High Definition (UHD) models, so you definitely have some options to consider.
The LG C1 OLED and the Samsung QN90A QLED are both excellent TVs, but they use different panels. The LG is an OLED with a near-infinite contrast ratio, nearly instant response time, and wide viewing angles. The Samsung has a VA panel, so it still has an excellent contrast ratio, but its viewing angles are only decent.
