This guide will break down exactly who each TV is best for when budget is a key factor.
Choosing a new TV can feel overwhelming, right? You want something that looks amazing, handles your favorite games and movies, and doesn’t empty your wallet. Two TVs that keep popping up for smart shoppers are the LG C3 and the Samsung S90C. They both promise that amazing OLED picture we all crave, but at prices that are becoming more accessible. Which one is the true “essential buy” when you’re looking for a deal? Don’t sweat it – I’m Bob E Riley from Aimguider, and I’m here to walk you through it, no fancy tech talk needed. We’ll figure out which of these fantastic OLEDs is your perfect match.
Understanding OLED Technology: Why It’s a Big Deal

Before we dive into the nitty-gritty of the LG C3 and Samsung S90C, let’s quickly chat about why OLED technology is so special. You’ve probably heard the hype – perfect blacks, incredible contrast, and vibrant colors. OLED stands for Organic Light-Emitting Diode. Unlike traditional LCD TVs that need a backlight to illuminate pixels, each individual pixel in an OLED display creates its own light.
This “self-emissive” nature is the key. When a pixel needs to be black, it simply turns off completely. This results in true, absolute black that LCDs simply cannot replicate. This perfect black leads to an almost infinite contrast ratio, meaning the difference between the brightest whites and darkest blacks is enormous, bringing incredible depth and realism to whatever you’re watching. Furthermore, OLED pixels can switch on and off incredibly fast, which is fantastic for action movies and fast-paced video games. The viewing angles are also typically much wider than on LCD TVs, so the picture looks great from almost anywhere in the room.
Finding an OLED TV at a “cheap” price point is becoming more realistic, especially during sales events like Black Friday or Prime Day, or as newer models are released. This makes the LG C3 and Samsung S90C particularly attractive for those looking for premium picture quality without paying top dollar.

LG C3: The All-Rounder Champion

LG has been a titan in the OLED space for years, and the C3 continues that legacy. It’s often considered the go-to for many because it strikes a fantastic balance between incredible picture quality, smart features, and gaming prowess. When you find the C3 at a “cheap” price, it’s a truly compelling purchase.
Picture Quality for Everyday Viewing
The LG C3 uses LG’s own WOLED technology. This means you get those signature OLED benefits: perfect blacks, infinite contrast, and incredibly wide viewing angles. For movies and TV shows, this translates to a breathtakingly immersive experience. Colors are rich and accurate, and the detail in both bright and dark scenes is phenomenal. LG’s Alpha 9 Gen6 processor does an excellent job of upscaling lower-resolution content and refining the image, making even older shows look fantastic on a large screen.
For general TV watching, sports, and streaming, the C3 is simply superb. The motion handling is smooth, and blooming (where light bleeds into dark areas) is virtually non-existent. It’s a TV that makes everything you watch look its absolute best, day in and day out.
Gaming Prowess: A Gamer’s Dream
This is where the LG C3 truly shines for many, especially when considering its value. It boasts an impressive four HDMI 2.1 ports. What does that mean for gamers? It means you can connect multiple next-gen consoles (like the PlayStation 5 and Xbox Series X) or a powerful PC and take full advantage of features like 4K gaming at 120Hz. Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) are also onboard, ensuring smooth, tear-free gameplay and minimal input lag. The C3 supports both NVIDIA G-Sync and AMD FreeSync, which are crucial for PC gamers who want the smoothest possible experience.
LG’s Game Optimizer menu is a brilliant addition, allowing you to quickly adjust picture settings tailored specifically for gaming. Whether you’re playing a competitive shooter or a cinematic RPG, the C3 delivers a responsive and visually stunning gaming experience. For gamers looking for a cheap OLED with no compromises on next-gen features, the C3 is a top contender.
Smart Features and User Experience
The C3 runs on LG’s webOS platform. It’s known for being intuitive, easy to navigate, and packed with all the streaming apps you could ever want (Netflix, Disney+, Hulu, Amazon Prime Video, etc.). The Magic Remote, with its point-and-click interface, makes browsing and selecting content a breeze. LG also offers decent built-in audio with its AI Sound Pro, which does a commendable job of virtualizing surround sound. While it won’t replace a dedicated soundbar or home theater system, it’s more than adequate for casual viewing.
Why the LG C3 Might Be Your Essential Buy:
- Exceptional all-around picture quality: Perfect blacks and stunning contrast for movies and TV.
- Top-tier gaming performance: Four HDMI 2.1 ports, 120Hz, VRR, ALLM, G-Sync/FreeSync support.
- User-friendly webOS: Simple to navigate with a vast app selection and helpful Magic Remote.
- Excellent viewing angles: Great for rooms where people sit off to the side.
- Reliable and proven OLED tech: LG has a long history of producing great OLED displays.
Samsung S90C: The QD-OLED Brightness and Color Powerhouse

Samsung has entered the OLED arena with its Quantum Dot OLED (QD-OLED) technology, and the S90C is a prime example of its impressive capabilities. QD-OLED aims to combine the perfect blacks of OLED with the enhanced brightness and color volume typically seen in Quantum Dot LCD TVs. When the S90C hits a “cheap” price, it presents a formidable argument as the essential buy, particularly for those who prioritize vibrant visuals and peak brightness.
Picture Quality: A Brighter, More Colorful OLED
The S90C’s QD-OLED panel is the star of the show. This technology uses blue OLEDs as a light source and adds Quantum Dots to convert that blue light into red and green. The result? Brighter whites and significantly wider color gamuts. Colors on the S90C are incredibly vibrant and pop off the screen, giving content a dazzling, almost hyper-realistic appearance. The contrast is still that signature OLED perfection, with deep blacks and excellent detail.
For HDR content (High Dynamic Range), the S90C’s higher peak brightness and expanded color volume can make a noticeable difference. Highlights in movies and games can appear more intense, and the overall image can have a more dynamic and impactful feel. If you watch a lot of HDR movies or play HDR games in a room with moderate ambient light, the S90C’s brightness can be a real advantage. While many still find the LG C3 plenty bright, the S90C often edges it out in peak brightness on specific highlights.
You can learn more about the benefits of Quantum Dot technology on Samsung’s educational pages, which highlight how it enhances color purity and brightness.
Gaming Features: Ready for Action
Samsung hasn’t skimped on gaming features with the S90C. It also features four HDMI 2.1 ports, supporting 4K resolution at 120Hz, VRR, and ALLM. This ensures that next-gen gaming experiences are smooth and responsive. The S90C supports AMD FreeSync Premium, which complements NVIDIA G-Sync compatibility on the C3. For most gamers, both are excellent for eliminating screen tearing and stuttering. Samsung’s Tizen OS also includes a Game Bar that provides quick access to gaming-specific settings and performance metrics.
Smart Features and Design: Sleek and Intuitive
The S90C runs on Samsung’s Tizen operating system. Like webOS, it’s a mature and feature-rich platform with access to all major streaming services. Tizen is known for its speed and ease of use. Some users prefer Tizen’s layout and app organization, while others prefer webOS. It’s largely a matter of personal preference. The S90C also boasts Samsung’s Object Tracking Sound Lite, which aims to create a more immersive audio experience by making it seem like the sound follows the on-screen action. The design of the S90C is typically very slim and elegant, with some models featuring the convenient One Connect Box to minimize cable clutter.
Why the Samsung S90C Might Be Your Essential Buy:
- Exceptional brightness and color volume: QD-OLED technology delivers incredibly vibrant and punchy visuals.
- Stunning HDR performance: Highlights really pop, making HDR content more impactful.
- Strong gaming features: Four HDMI 2.1 ports, 120Hz, VRR, and ALLM.
- Sleek, modern design: Often features an ultra-slim profile.
- Vibrant and lively picture: Can be preferred by those who like a very dynamic image.
Key Differences Explained for Beginners

Let’s break down the core differences between the LG C3 and Samsung S90C in plain language so you can see which one aligns best with your needs, especially when hunting for a “cheap” deal.
1. Panel Technology: WOLED vs. QD-OLED
LG C3 (WOLED): This is LG’s established OLED tech. It’s fantastic at delivering perfect blacks and great contrast across the entire screen. It’s wonderfully balanced.
Samsung S90C (QD-OLED): This is Samsung’s newer approach. It blends OLED’s perfect blacks with Quantum Dots. This combo tends to push brightness higher and makes colors even more vivid and saturated. Think of it as OLED with an extra boost.

Samsung S90C: Generally achieves higher peak brightness, especially in small highlights and for HDR content. This makes it stand out more in rooms with some ambient light or when watching very bright HDR movies.
3. Color
LG C3: Produces very accurate and natural-looking colors.
Samsung S90C: Thanks to Quantum Dots, the S90C can achieve a wider color gamut, meaning it can display more shades and more intense versions of colors. This can make content look incredibly vivid.
4. Gaming Ports
Both C3 and S90C: Offer four full HDMI 2.1 ports. This is excellent for gamers who need to connect multiple next-gen consoles or PCs and want all the latest gaming features (4K@120Hz, VRR, ALLM). There’s no significant advantage for either here, which is great news for gamers looking for a deal.
5. Operating System
LG C3 (webOS): Very user-friendly, intuitive with a pointer remote. Loads of apps.
* Samsung S90C (Tizen OS): Also very user-friendly, fast, and has all the major apps.
The choice between them often comes down to personal preference for color vibrancy and peak brightness versus a slightly more understated, yet still phenomenal, color reproduction.
Who Should Buy the LG C3 When It’s Cheap?
If you’re a gamer who prioritizes having the most flexible gaming setup, the LG C3 with its four full HDMI 2.1 ports is an absolute dream. Combine that with G-Sync/FreeSync support and LG’s excellent motion processing, and you have a TV built for serious gaming.
The C3 is also perfect for those who watch a lot of varied content and appreciate natural, accurate colors. If you often watch in a dimly lit room or a dedicated home theater space, the C3’s deep blacks and perfect contrast are outstanding. It’s the reliable workhorse that makes everything look good, all the time, without being overly flashy. For many, it represents the sweet spot of premium OLED performance and value when found on sale.
Who Should Buy the Samsung S90C When It’s Cheap?
If you want your TV to truly grab your attention with dazzling colors and impressive brightness, the Samsung S90C is the better choice. Its QD-OLED technology makes HDR content pop like never before, and the overall image can appear more dynamic and vibrant.
This TV is ideal for those who enjoy watching a lot of movies and shows with vibrant cinematography or playing video games where striking colors and bright highlights are a key part of the experience. If your room has some ambient light, the S90C’s higher peak brightness can help combat glare and maintain a more impactful picture. For those who crave that “wow factor” in color and brightness, and can snag it at a discounted price, the S90C is hard to beat.
Finding the “Cheap” Deal: Tips for Smart Shopping
The term “cheap” is relative, especially when discussing premium OLED technology. However, finding these TVs at significantly reduced prices is achievable with smart shopping.
- Timing is Key: The best time to find deals is typically around major holiday sales events. Think Black Friday, Cyber Monday, President’s Day, and even summer sales. Newer models usually launch in early spring, so preceding months often see discounts on the previous year’s model.
- Compare Retailers: Don’t stick to just one store. Big box retailers (Best Buy, Costco, etc.), online giants (Amazon, Walmart), and even manufacturer websites often have different pricing and promotions.
- Look for Open-Box or Refurbished: If you’re comfortable with it, open-box or certified refurbished units from reputable sellers can offer substantial savings. Always check the warranty and return policy.
- Consider Slightly Older Models: While we’re comparing C3 and S90C, if you see a C2 or an older S95B/QD-A80K at a significantly lower price, they might still be excellent value for money, though you’ll miss out on the latest processor improvements.
- Sign Up for Alerts: Many deal websites and retailer newsletters can notify you when prices drop on specific models.
Patience and comparison are your best friends when hunting for a great deal on these high-end TVs. For example, sites like Rtings.com offer detailed comparison tools that can help you track price history and performance metrics side-by-side.
