Both the Samsung Neo QLED QN90A and LG C1 OLED are slim and sleek TVs with premium design features.

Both Samsung and LG’s premium TVs boast futuristic and minimal designs.

The Samsung Neo QLED QN90A and LG C1 OLED are both high-end units that sport sleek and minimalist aesthetics. Samsung’s 55-inch 4K TV has a premium exterior that draws inspiration from sibling models like the Q90 series but with a much thinner frame. This super slim form โ€” less than an inch in depth โ€” is complemented by an almost bezel-less display for a more immersive viewing experience.

LG’s C1, on the other hand, builds on the design language of the brand’s C Series. Although it’s a familiar look, the all-glass display of the C1 is one of the most polished in the market today. Like Samsung’s Neo QLED, a side view reveals an ultra-thin form as well.

Where the two models largely differ is in their stands. On the LG C1, the stand is almost as wide as the TV itself. Despite taking up a lot of space, this approach offers enough support for the screen. Samsung’s QN90A, on the other hand, has a central stand that, though stable, feels wobbly. Nonetheless, it does offer better height compared to the LG C1, which makes the Samsung Neo QLED more accommodating of soundbars.

If you’re not fond of setting them up on a console or table, you can mount these TVs. Both the Samsung QLED QN90A and the 65-inch LG C1 OLED come with VESA wall mounts.


The Samsung Neo QLED QN90A has the edge when it comes to brightness. However, LG’s C1 OLED TV leads when it comes to contrast, details, and consistency across viewing angles.

Here’s a look at the different display technologies used by the Samsung Neo QLED (left) and LG OLED (right).

Choosing between the Samsung QN90A and LG C1 depends on whether you prefer QLED or OLED technology. QLED is essentially a variation of traditional LCDs. Here, Samsung’s 55-inch unit uses an array of mini-LED lights that allow for improved brightness and dimming. These are powered by Samsung’s Neo Quantum Processor 4K. If you want a TV that can combat glare easily, the QN90A is the way to go.

LG’s OLED TV, on the other hand, uses a vastly different type of tech. Unlike LCDs, OLED does away with an LED backlight and instead uses millions of self-lighting pixels. On the C1, the result is much more consistent picture quality across the different TV sizes. LG’s 65-inch TV also benefits from infinite contrast and more intense colors. While it doesn’t get as bright as a QLED TV, the LG C1 has the edge when it comes to fidelity across viewing angles.

In terms of resolution, the two offer similar feature sets. Both Samsung’s Neo QLED and LG’s OLED TV support 4K resolution. The units also enjoy a 120Hz refresh rate. While both have impressively short lag times, the LG C1 is the better gaming TV. Aside from the presence of HDMI 2.1, it comes with a dedicated gaming optimizer menu. It also supports Dolby Vision HDR and is compatible with NVIDIA’s G Sync.

Sound Quality

The sound quality on both the Samsung Neo QLED and LG OLED TVs is a bit of a step down from their impressive picture quality.

Samsung Neo QLED vs LG OLED Sound Quality Review
The sound quality you get from these models is better than your standard TV.

Both the Samsung QN90A and LG C1 offer solid although unexceptional audio performance. Equipped with a 4.2.2-channel speaker system (60W), the Neo QLED TV is designed to project sound across all sides. The integrated speakers also work best with Samsung’s Object Tracking Sound+ (OTS+) technology, lending a directional and realistic sound quality.

It’s a great alternative since the QN90A lacks a native Dolby Atmos. Even though the bass is average, the overall quality is a dynamic sound that keeps up with whatever’s shown on screen.

Meanwhile, the LG C1 comes with a 2.2 channel audio (40W output) that offers great clarity across a range of content. Even on fairly loud tracks or shows, LG’s speakers handle it consistently. Unlike the Samsung Neo QLED, however, the C1 comes with Dolby Atmos. It also features AI Sound Pro that optimizes audio settings depending on the content being watched.

Still, the overall sound quality on the LG C1 is a step below its more impressive picture quality. Fortunately, the availability of standalone soundbars should make it easy to upgrade your viewing experience.

Smart Features

While both TVs come with a solid smart TV feature set, the Samsung Neo QLED QN90A offers access to more apps than the LG C1 OLED TV.

Of course, a Samsung Neo QLED 4K TV will not be complete without smart features. On the QN90A, you get on board the Tizen platform that offers both apps and a full web browser. LG’s C1 OLED TV, on the other hand, runs on webOS. Both platforms are streamlined and fairly easy to navigate, with less clutter compared to other TV iterations in Samsung and LG’s catalog.

Like many smart TVs, the QN90A and C1 include content from favorite streaming services like Netflix, Apple TV, and YouTube. Samsung, however, has the edge when it comes to the number of available apps from its app store. Both TVs also carry smart remote controls that boast more quick access keys and app shortcuts. The LG C1’s inclusion of an intuitive scroll wheel, however, gives it the edge over the Samsung QN90A.

The Samsung Neo QLED and LG OLED TVs support voice assistants, too. Alexa and Google Assistant are built-in to the LG C1 OLED. Meanwhile, Samsung brings the same two assistants but adds the company’s very own Bixby into the mix.


Get the LG C1 OLED TV if you want the best picture quality in the market. Opt for the Samsung Neo QLED if you need a bright TV with plenty of apps.

Choosing between a Samsung Neo QLED TV and an LG OLED TV boils down to preference โ€” and budget. After all, both TVs share a similar sleek and futuristic design you only get to enjoy on a high-end model. Like other QLED TVs, Samsung’s 55-inch QN90A banks on its impressive brightness. It also anchors itself on the expansive apps available on the Tizen platform. Plus, it’s the less expensive TV of the two.

LG’s C1, on the other hand, relies on the impressive and consistent picture quality available only to OLED TVs. While it may not get as bright as the Samsung QN90A, the 65-inch LG C1 leads in contrast, sharpness, and detail. It makes a great gaming TV, too, thanks to dedicated ports and compatibility with different gaming platforms. The only downside to this feature set is that you’ll end up shelling more dollars.
