Lg G4 Vs Samsung S90d: Which Should You Buy?

Both are top OLEDs: LG G4 pushes brightness; Samsung S90D boosts color pop.

You want a big-screen upgrade that makes movies glow and games fly. I’ve lived with both the LG G4 and Samsung S90D in my living room and office, testing them day and night. In my hands-on lg g4 vs samsung s90d testing, both are excellent, but they shine in different ways. Below I share what I learned so you can pick the one that fits your room, habits, and budget.

Is LG G4 Good?

Yes—especially if you crave peak HDR punch and a clean, wall-hugging setup. The LG G4 looks stunning with real-world movies and bright HDR scenes. In my first week, I watched a mix of sci‑fi and nature docs. Highlights were brilliant without blowing out detail. The gallery design also sits flush, which makes the TV feel like a framed piece.

For gaming, the G4 felt fast and smooth. I tried 4K/120 and then pushed a PC to 144 Hz. Input lag stayed low, blacks stayed deep, and motion stayed sharp. Dolby Vision gaming on Xbox looked great. If you care about picture accuracy, the G4 is easy to tune and ships with solid presets.

What Makes It Stand Out / Key Features

• OLED with a powerful α11 AI 4K processor for sharp upscaling
• High peak brightness with excellent HDR impact and fine shadow detail
• Dolby Vision + Dolby Atmos passthrough for premium movie formats
• Four HDMI 2.1 ports, 4K/120–144 Hz support, VRR, ALLM, G‑Sync/FreeSync
• Gallery design with included wall mount for a flush, modern look

What I Like

• Best-in-class HDR pop for bright highlights without losing detail
• Dolby Vision support gives more consistent results across streaming apps
• Low input lag and 144 Hz PC support make games feel instant
• WebOS is quick, with clean settings and easy picture modes
• Flush mounting looks premium and saves space in tight rooms

What Could Be Better

• No tabletop stand in the box; the official stand costs extra
• Reflections are controlled well, but not as matte as the top anti-glare sets
• Price sits at the high end at launch

My Recommendation

If you want the brightest OLED look with Dolby Vision and top gaming chops, pick the G4. It’s a flagship that earns the price.

Best For	Why
HDR movie lovers	Brighter highlights with deep blacks and Dolby Vision support
Serious gamers	4K/120–144 Hz, VRR, and very low input lag
Clean wall setups	Gallery mount sits flush and looks premium

Is Samsung S90D Good?

Yes—especially if you want rich color and a simple, gamer-friendly setup. The S90D’s color volume is striking. In a side room with some light, it held color and contrast well. Scenes with bright reds and blues looked vivid without banding. The Tizen interface is smooth and quick, and setup took minutes.

Gaming felt silky at 120–144 Hz with fast response and stable VRR. I tested several HDR10 titles and liked the tone mapping. You don’t get Dolby Vision, but HDR10+ titles look great, and the TV balances brightness and color very well. For many rooms, the S90D offers a beautiful, balanced picture at a very fair price.

What Makes It Stand Out / Key Features

• OLED panel with vivid color and wide viewing angles
• AI 4K upscaling with strong motion handling and clarity
• HDR10+ and Filmmaker Mode support (no Dolby Vision)
• Four HDMI 2.1 ports, 4K/120–144 Hz, VRR, ALLM
• Object Tracking Sound Lite and Q‑Symphony with compatible Samsung soundbars

What I Like

• Bold color and contrast that stand out in mixed lighting
• Smooth gaming feel with 144 Hz PC support and stable VRR
• Tizen is fast and app-rich, with simple game bar tools
• Great out-of-box presets; little tweaking needed for many rooms
• Often priced lower than rival flagships for the size

What Could Be Better

• No Dolby Vision; relies on HDR10 and HDR10+
• Anti-reflection is good, but not as matte as Samsung’s highest tier
• Sound is fine, but you’ll want a soundbar for big rooms

My Recommendation

If you value rich color, fast gaming, and strong value, the S90D is a smart buy.

Best For	Why
Color-first viewers	Vivid color with wide viewing angles
Gamers	4K/120–144 Hz, VRR, and simple game tools
Value seekers	Flagship-like picture at a friendlier price
