The S90C offers dazzling brightness for less, while the C4 delivers refined processing and newer features.

Choosing a new OLED TV can feel like navigating a minefield of technical jargon. You just want a screen that makes movie night feel like a trip to the cinema and your gaming sessions look absolutely stunning. That's the exact spot where the Samsung S90C vs LG C4 debate comes into play. Both promise perfect blacks and incredible contrast, but they achieve it in different ways. I’ve had both of these sets in my living room, running them through their paces with everything from blockbuster films to fast-paced gaming, and I’m here to break it all down for you.

Is Samsung S90C Good?

Yes, the Samsung S90C is an absolutely fantastic television, especially for those who prioritize vibrant, bright, and punchy picture quality. It uses Quantum Dot OLED (QD-OLED) technology, which allows it to produce incredibly vivid colors and get brighter than many of its competitors. This makes it a stellar choice for rooms that aren't completely dark, where that extra brightness really helps the image pop off the screen and combat ambient light. It’s a TV that grabs your attention from the moment you turn it on.

I remember setting up the S90C and putting on a 4K nature documentary. The sheer intensity of the colors—the deep blues of the ocean and the electric greens of a rainforest—was breathtaking. Later that week, I was playing a fast-paced shooter, and the TV's low input lag and smooth motion handling made the experience incredibly responsive. It felt like I had a competitive edge simply because the display was so clear and immediate. For anyone who wants a "wow" factor, the S90C delivers in spades.

What Makes It Stand Out / Key Features

• Quantum Dot OLED (QD-OLED) Panel: Combines the perfect blacks of OLED with the color volume and brightness of Quantum Dots.
• Neural Quantum Processor 4K: An AI-powered processor that expertly upscales content and optimizes picture quality in real-time.
• Samsung Gaming Hub: Allows you to stream games from Xbox, NVIDIA GeForce Now, and more, directly through the TV without a console.

• Its ultra-slim profile makes it one of the best-looking TVs on the market.

What Could Be Better

• It lacks support for Dolby Vision, which is a preferred HDR format for many streaming services like Netflix.
• The Tizen OS interface can feel a bit cluttered with ads and recommendations.
• While the built-in sound is decent, it lacks the bass to match the stunning visuals.

My Recommendation

Is LG C4 Good?

Absolutely. The LG C4 is an outstanding TV that represents a refinement of LG's already legendary C-series OLEDs. It's the quintessential all-rounder, delivering a superbly accurate and cinematic picture that will please movie purists. Its strength lies in its new a9 AI Processor Gen7, which offers some of the best image processing on the market. This means motion looks incredibly smooth, and upscaled content from lower resolutions looks sharp and clean. It’s the safe, reliable, and expertly crafted choice.

My time with the C4 was spent re-watching some of my favorite dark and moody films. Watching The Batman, I was amazed by the TV's ability to pull out subtle details in the darkest shadows without crushing the blacks. The Dolby Vision support made a noticeable difference, presenting the film exactly as the director intended. I also found the WebOS 24 interface and the Magic Remote to be incredibly intuitive. Navigating menus and finding content was effortless, making the day-to-day experience of using the TV an absolute pleasure.

What I Like

• The picture accuracy out of the box is phenomenal, especially in Filmmaker Mode.
• Support for Dolby Vision provides a clear advantage for movie and TV show lovers.
• The Magic Remote makes navigating the smart TV interface a uniquely simple and enjoyable experience.
• Motion handling is arguably the best in the business, making fast-action sports and movies look incredibly smooth.
• WebOS is clean, fast, and less intrusive with advertisements compared to some competitors.

What Could Be Better

• While brighter than past models, it can't match the peak brightness and color volume of the QD-OLED S90C.
• The central stand design, while sturdy, might not fit on all media consoles.

My Recommendation

The LG C4 is the perfect TV for cinephiles and anyone who values picture accuracy, a user-friendly interface, and the full cinematic experience with Dolby Vision. It's a polished, premium, and incredibly capable all-rounder.

Best For	Why
Movie Buffs	Its support for Dolby Vision and exceptional processing delivers a true cinematic picture.
Users Wanting Simplicity	The combination of WebOS and the Magic Remote is the most intuitive smart TV experience.
General Use	It excels at everything from movies and TV shows to sports and gaming.

Samsung s90c vs Lg c4: Side-by-Side Test

After spending quality time with both TVs, I ran them through a series of direct comparisons to see where each one truly shines. The battle of Samsung S90C vs LG C4 is a clash of two different OLED philosophies: Samsung's pursuit of vibrant brightness versus LG's focus on refined accuracy.

Sound Quality

Neither TV will replace a dedicated soundbar, but they offer decent onboard audio. The S90C uses Object Tracking Sound Lite to create a sense of sound moving with the action. The LG C4 leverages its AI processor for AI Sound Pro, which does a great job of up-mixing audio to virtual 9.1.2 channels and enhancing dialogue clarity. The C4's support for Dolby Atmos gives it a slight edge for compatible content.

Value for Money

This is a key factor in the Samsung S90C vs LG C4 comparison. As a 2023 model, the Samsung S90C is often available at a significant discount compared to the brand new 2024 LG C4. You are getting flagship-level brightness and gaming performance for a mid-range price, which is an incredible proposition. The C4 justifies its price with newer processing and features, but the value of the S90C is undeniable.

Final Verdict: Which Should You Buy?

After extensive testing, the choice between the Samsung S90C vs LG C4 comes down to your priorities and your wallet. Both are exceptional TVs that represent the pinnacle of current OLED technology, but they cater to slightly different users. If you want the most vibrant, punchy, and bright picture possible, especially for gaming and watching in a room with some lights on, the Samsung S90C is the clear winner. Its QD-OLED panel is a force of nature, and its frequent discounts make it an almost unbeatable value proposition.

However, if you are a movie purist who craves picture accuracy and the ultimate cinematic experience, the LG C4 is the TV for you. Its superior image processing, support for Dolby Vision, and incredibly user-friendly WebOS platform create a more refined and polished package. It’s the ideal choice for those building a dedicated home theater and who want their films to look exactly as the director intended. Ultimately, you can't go wrong with either, but knowing what you value most will make the decision an easy one.

FAQs Of Samsung s90c vs Lg c4

What is the main difference between QD-OLED (S90C) and WOLED (C4)?

The main difference is how they create color. Samsung's QD-OLED uses a blue OLED layer to excite red and green quantum dots, creating pure RGB colors without a white subpixel. This leads to higher color purity and brightness. LG's WOLED uses a white subpixel alongside red, green, and blue ones to boost brightness, which can slightly wash out the most saturated colors at peak brightness compared to QD-OLED.

For a PS5 or Xbox Series X, is the Samsung S90C vs LG C4 a clear choice?

No, it's not a clear choice as both are among the best gaming TVs available. Both support 4K at 144Hz (and 120Hz for consoles), VRR, and have incredibly low input lag. The S90C's extra brightness can make HDR games look more impactful, while the C4 boasts official G-Sync compatibility, which may appeal to PC gamers who also connect their rig to the TV.

Does the lack of Dolby Vision on the Samsung S90C really matter?

For many people, no. The S90C supports HDR10+, which is a similar dynamic HDR format used by services like Amazon Prime Video. Its native brightness is so high that it produces a spectacular HDR image regardless. However, if you watch a lot of Netflix or use physical 4K Blu-rays, which heavily favor Dolby Vision, you will get a more accurate, director-intended HDR presentation on the LG C4.

Which is better for bright room viewing, the Samsung S90C or LG C4?

The Samsung S90C is noticeably better for bright room viewing. Its QD-OLED panel can achieve higher peak brightness levels across the entire screen. This allows it to more effectively overcome ambient light and reflections, making the picture appear punchier and more vibrant during daytime viewing.

Is the newer LG C4 always better than the older Samsung S90C?

Not necessarily. While the LG C4 is a newer 2024 model with a more advanced processor, the Samsung S90C (a 2023 model) has a fundamental panel advantage with its QD-OLED technology, especially concerning brightness and color volume. For pure visual impact, many would argue the older S90C is still superior, and it often comes at a much lower price, making it a better value.
