The two flagships of the Korean manufacturers Samsung and LG are competing against each other this time. The question of whether to buy a QLED or an OLED is one that arises quite quickly when buying high-end TVs, as the two technologies and the associated advantages and disadvantages are fundamentally different. Find out in the following comparison which TV is the right one for your needs!

Detailed comparison: Samsung Q90T or LG CX
The Samsung Q90T QLED is a true all-round TV that produces outstanding picture quality under practically all conditions.Due to its high peak brightness and equally good reflective properties, it is also ideal for bright rooms where OLEDs such as the CX have considerable problems producing a high-quality picture. Furthermore, it does not need a disturbing Automatic Brightness Limiter, which is used as burn-in protection for OLEDs. Due to the high peak brightness, High Dynamic Range - image/video with more dynamic range (contrast range) content is displayed in a great way and the extremely wide color The complete subset of colors which can be displayed by the screen ensures vivid and rich colors. Unfortunately, no 2020 Samsung TV supports Dynamic HDR-format with a color depth of up to 12 Bits and Mastering of up to 10,000 Nits, which is a pity especially with the Q90T. Dynamic HDR-format with a color depth of up to 12 Bits and Mastering of up to 10,000 Nits dynamically optimizes High Dynamic Range - image/video with more dynamic range (contrast range) content and thus it could be displayed much better. It also has an excellent Time it takes for a pixel to change color of less than 4ms, which also makes its Displaying fast moving objects outstanding.
It is no secret that the LG CX OLED is one of the best TVs in 2020. Due to the OLED construction it has perfect blacks and a theoretically infinite contrast ratio. Ordinary LCD = Liquid Crystal Display - a type of screen using liquid crystals for creating the image displays, such as the Q90T, cannot achieve the resulting outstanding picture quality in dark environments due to their design. In very bright rooms, however, OLEDs have a less convincing picture quality because they cannot become as bright as QLEDs. Although our comparison graphic shows that its viewing angle is still a little wider than that of the Q90T, this difference is not really noticeable under normal conditions. As far as gaming is an issue, both TVs are equally great to use. Both TVs have all the features you need for gaming. HDMI 2.1, Variable Refresh Rate - synchronizes the display's refresh rate with the output refresh rate of the graphics card, ALLM and a low Time it takes for the input signal to appear on the screen (delay) are present on both devices. Only the better Displaying fast moving objects of the CX causes a little less motion blur.

Our conclusion: Excellent TVs with different characteristics
The LG CX OLED and the Samsung Q90T are both excellent TVs, which will probably satisfy most users. It is not easy to say which TV is the better one in direct comparison. It rather depends on what kind of requirements you have for a TV. If you want the better home cinema feeling, with an almost unbeatable picture quality in dark surroundings, then you should rather get the LG CX OLED. It can also be used in brighter rooms, but its picture quality decreases with increasing ambient brightness. But if you want to have an all-rounder that produces a great picture under almost all conditions with a high peak brightness, the Q90T would be a good choice for you. In dark environments it can’t quite keep up with the CX, but it still has an impressive picture quality. High Dynamic Range – image/video with more dynamic range (contrast range) is brilliantly displayed by both devices, but the CX can crow with Dynamic HDR-format with a color depth of up to 12 Bits and Mastering of up to 10,000 Nits IQ, which allows for dynamic optimization of content – Samsung has unfortunately skipped this on the Q90T.
Both TVs can excellently be used for Gaming, since both have all features you might need for a high-end gaming experience.
