LG OLED evo C37 2023

With the Brightness Booster, the panel of the LG OLED evo C3 from the upper mid-range again delivers a little more picture performance in 2023. The powerful 6th generation Alpha9 processor provides increased processing power. Features like HDR10 Pro and Dolby Vision offer an expanded colour space. The Game Optimizer clearly summarises all important gaming features. A modular stand makes it easy to attach compatible LG soundbars.

With the Samsung S90C QD-OLED, Samsung has launched a scaled-down version of the S95C based on the so-called LaserSlim design. This means that the casing is not quite as thin as its big brother with the Infinity Design. The popular One Connect is also not part of the scope of delivery. Nevertheless, essential features such as high luminance, good reflection retention and a frame rate of 144 hertz are maintained when used as a monitor on a computer.

Reflections Comparison

Visible reduction of direct light incidence

Both the C3 and the S90C have a reflective coating that reduces glare. The Samsung model is really good in this respect and reduces direct light nicely.

In contrast to the larger G3, the smaller brother avoids a large part of the violet colour cast and at the same time ensures less intense reflections on the panel. With the QD OLED, on the other hand, you see a pinkish hue as soon as the device is switched off.

Consistent quality for all

OLED TVs are known to offer amazingly wide viewing angles, which are clearly one of the advantages of this technology. As a result, quality losses are practically non-existent on both devices.

So you can comfortably watch the screen in larger company without having to worry about quality disadvantages due to an unfavourable positioning relative to the screen. However, if you regularly watch in a large group, a size of over 70 inches might make sense.

Hardly any differences worth mentioning

When using the smaller SDR colour space, the C3 in particular achieves a better result across the entire screen surface. As expected, smaller areas of brightness are not reproduced that brightly.

While the automatic brightness limiter on the LG – even compared to its predecessor – is not quite as aggressive, the function on the S90C dims the picture brightness visibly more to the disadvantage of displaying bright picture content.

Increased dimming on the Samsung

While the C3 is not quite in the upper brightness range, the Samsung S90C generally manages to jump above 1000 nits. On the other hand, the LG shows less ABL aggressiveness during longer viewing of bright HDR content. Samsung’s QD OLED does feature particularly vivid highlights, but large bright scenes are then clipped harder by the automatic brightness control.

However, the luminance on the panel cannot compete with the values of the step-up model. Despite the progress in the OLED sector over the past few years, the technology is still only suitable to a limited extent for viewing in bright and very bright lighting conditions.

Wide range of equipment for your home cinema

Optimal black levels without disturbing blooming effects and access to popular streaming services are available on both devices. However, you will find differences in the support of HDR formats: While LG uses Dolby Vision as usual, including the ambient light-dependent IQ variant and classic HDR10, Samsung offers HDR10+ and HDR10+ Adaptive. It saves on the licensing of the Dolby standard. IMAX content is not supported either.

Equipped with lots of gaming functions

If you are looking for a TV with low input lag and expect a fast response time, both TVs are an attractive option for you. If you have a powerful computer, you can even push the panel up to a refresh rate of 144 hertz with the S90C.

An additional set of features such as variable frame rate, AMD FreeSync and Nvidia G-Sync further enhances the package in this area. Fans of Dolby Vision Gaming can look forward to corresponding support. However, this applies to the TV from LG. Samsung continues not to offer the format.

Sharp and smooth

With interpolation switched on, you get a frame rate of 120 hertz in normal TV mode. Sporting events with a lot of movement and fast camera pans can thus be output clearly and without any noteworthy motion blur.

Thanks to the uniform display of colour areas, the screens also ensure a clean display of game fields. So you don’t have to fear spot islands or unclean colour gradients.

Versatile equipped

Both the LG and the Samsung provide you with several voice assistants at the same time. Among them are Alexa and Google. In the S90C, you can also use Bixby. On the C3, you will get the counterpart called ThinQ. Both models have an ultra-slim casing design.

Thanks to Q-Symphony, you can add compatible speakers to your setup. In principle, this is also possible via the WiSA Standard on the C series model – for example, with the C39LC sales variant.

You can output uncompressed Dolby Atmos sound via eARC. DTS:X, on the other hand, is only an option on the LG. But there it is only available as a forwarded sound signal. Direct output via the TV speakers is not possible. In terms of size diversity, the QD family is smaller overall, having only three sizes available.

Our conclusion:
Sharper brightness vs slight downgrade

Both models present an anticipated typical OLED quality, which is characterised by deep blacks, high contrast and wide viewing angles. Despite more aggressive brightness dimming, the QD TV stands out slightly in our comparison between the LG OLED evo C3 vs Samsung S90C QD-OLED.

When it comes to gaming, the TVs score with low lag, fast response time and features like a dynamic picture sync and of course 4K at a refresh rate of 120 hertz.

In summary, both the LG OLED evo C3 and the Samsung Q90C QD-OLED are reliable TVs with strong specifications. Ultimately, the decision for one of these devices will depend on individual preferences and needs.
