SUHD (Super Ultra High Definition) combines UHD resolution with a Nano Crystal display so that SUHD creates an even greater spectrum and more accurate reproduction of colour.

While SUHD TVs focus on the use of quantum dot nanocrystal layers in their screens, LG's OLED TVs offer the deepest blacks possible because of their organic light emitting diodes, which can individually shut themselves off where needed for a particular image.

In LED TVs, good picture quality is seen in QLED TVs with good contrast ratios [ with HDR, dimming and other technologies ]. You can get a SUHD TV much cheaper than OLED TV. In short, if money is not a matter and you are ok with shorter life span of the TV, go with the OLED. It provides the best viewing experience.

SUHD falls between LED and QLED, offering a mid-range solution with impressive picture enhancements. In summary, each display technology has its strengths and caters to different needs. Consider your viewing environment, content preferences, and budget to find the display technology that best suits you.

While quantum dot filters increase colour definition and brightness, as LCD TVs, SUHD products do still use an external backlight system to illuminate pixels. The ideal scenario is for each pixel to produce its own individual light – like OLED TVs do.

Any TV with a resolution higher than 1080P is known as ultra HD TV ( 4K TV is also an ultra HD TV with a resolution of 3840X2160) whereas smart TV is the one which can be connected to the internet through WiFi/ethernet port and which has popular applications like prime video or YouTube in built.

The displays of 4K UHD produces accurate colors but, as in many LCDs and LEDs, the richness is not comparatively high as the SUHD TVs. The SUHD is better in providing rich information, a realistic and deep display than the 4K UHD.

What is the difference between UHD and SUHD? UHD and Su HD both are 4K with a resolution of 3840 X 2160.

This can be also referred as 4K progressive or 4 times HD resolution. The displays of 4K UHD produces accurate colors but, as in many LCDs and LEDs, the richness is not comparatively high as the SUHD TVs. The SUHD is better in providing rich information, a realistic and deep display than the 4K UHD.

It comes across more refined, cleaner and more defined than the previous 4K TVs. To me, it's a 10% improvement in color representation. Next, the SUHD lineup has a brigher backlight which is capable of hitting 1000 nits at peak brightness and produce deeper blacks as well, though this is more difficule to discern.

Ultra High Definition (UHD) is the resolution 3840x2160P. What this means is that there are more pixels per inch (PPI) in a UHD TV. This gives a higher resolution on the TV. UHD is used on larger TVs so you can sit closer to the TV and still enjoy a crisp, clear picture.
