LG OLED65G5WUA vs Samsung QN90C 65": The Ultimate TV Showdown

In the battle of premium 65-inch TVs, the Samsung QN90C 65" emerges as the clear winner. While both sets deliver stunning visuals, Samsung's superior brightness and HDR performance give it the edge for most modern living rooms and varied lighting conditions.

Key Specifications Comparison

Brightness and HDR Performance: Samsung Dominates

The most striking difference between these two flagships lies in their HDR output. The Samsung QN90C crushes the competition with peak brightness levels reaching an impressive 2500 nits in real-world testing. This isn't just marketing hype – it translates to dazzling highlights in everything from sun-drenched desert scenes in Dune to explosive action sequences in the latest blockbusters. The LG OLED65G5WUA, while respectable at around 1200 nits, simply cannot match this intensity.

This brightness advantage makes the Samsung the superior choice for rooms with ambient light or windows. The Mini-LED backlight with over 1,000 dimming zones delivers punchy, well-controlled highlights without the aggressive dimming sometimes seen on OLED panels during bright scenes. If you want your HDR content to truly pop with eye-searing intensity, Samsung is the undisputed champion here. The LG isn't bad by any means, but it feels restrained in comparison – like comparing a sports car to a supercar on the same track.

Contrast and Black Levels: LG's OLED Magic

While Samsung wins the brightness battle, LG takes the crown for pure cinematic performance in controlled lighting. The OLED65G5WUA's self-emissive pixels deliver perfect blacks and an infinite contrast ratio that the QN90C simply cannot match, even with its advanced local dimming. Our measurements showed the LG achieving a staggering 1,000,000:1 contrast ratio versus Samsung's already excellent 500,000:1.

This translates to breathtaking performance when watching in a darkened room. Shadow detail in films like The Batman appears with incredible depth and nuance that the Samsung cannot fully replicate. The LG's perfect blacks make every scene feel more three-dimensional and immersive. If your primary use case is dedicated movie nights with the lights off, the LG OLED65G5WUA is the more emotionally engaging option. Samsung's local dimming, while impressive, still shows some blooming around bright objects on dark backgrounds – a flaw the OLED completely avoids.

Gaming Performance and Features

Both televisions are gaming powerhouses equipped with four HDMI 2.1 ports, 144Hz refresh rates, VRR, and ALLM. However, the Samsung QN90C pulls ahead with its slightly lower input lag and more responsive feel in fast-paced titles. The combination of extreme brightness and high refresh rate makes motion handling feel almost unreal – explosions and rapid camera movements look incredibly sharp without any blurring.

The LG isn't far behind and actually offers slightly better support for Dolby Vision gaming, which some consoles and PCs can take advantage of. Its pixel response time is technically faster due to the OLED nature, eliminating any ghosting in dark scenes. Both sets include excellent game bars and cloud gaming integration. For competitive gamers chasing every millisecond of advantage, Samsung feels marginally more responsive, but the difference is small enough that most players would be thrilled with either.

Design, Sound Quality, and Smart Features

The LG OLED65G5WUA features the brand's acclaimed Gallery Design – it's incredibly thin and mounts flush against the wall like a piece of art. The Samsung QN90C uses a more traditional but still premium design with minimal bezels and a sturdy stand. Both look fantastic, but LG wins for those wanting a wall-mounted, picture-frame aesthetic.

In terms of audio, Samsung's 60W 4.2.2 channel system with Object Tracking Sound outperforms LG's 40W setup. The QN90C creates a more immersive soundstage that better matches its brilliant picture. Neither replaces a dedicated soundbar for audiophiles, but Samsung's built-in audio is noticeably more powerful and cinematic.

Smart platform preference is subjective. LG's webOS is buttery smooth with excellent remote functionality, while Samsung's Tizen offers faster navigation and better integration with SmartThings devices. Both support all major streaming apps without issue.

Who Should Buy Which?

Buy the Samsung QN90C 65" if:

• You watch TV in a room with windows or ambient lighting
• HDR performance and brightness are your top priorities
• You want the best value in a premium TV
• Gaming on a bright screen with incredible highlights matters most
• You prefer powerful built-in speakers

Buy the LG OLED65G5WUA if:

• You have a dedicated dark media room
• Perfect blacks and infinite contrast are non-negotiable
• You love the Gallery wall-mount design
• You primarily watch cinematic content in controlled lighting
• Dolby Vision support is important to you

Final Verdict

The Samsung QN90C 65" is the superior overall television for most buyers. Here's why:

• Overwhelming brightness advantage – 2500 nits versus 1200 nits makes HDR content significantly more impactful in real-world conditions.
• Better value – Typically priced lower while delivering more versatile performance across different environments.
• Stronger overall feature set including superior audio and slightly better gaming responsiveness.
• More future-proof for the growing library of bright, dynamic HDR content being produced today.

That said, the LG OLED65G5WUA remains an exceptional choice for purists who prioritize perfect contrast above all else. Its cinematic performance in a dark room is unmatched by any LED/LCD television. However, when we look at the complete package – versatility, brightness, value, and overall performance – the Samsung QN90C earns its victory. At these price points, both are excellent investments, but Samsung simply does more things at a higher level for the majority of consumers. If your room allows for light control and movies are your main focus, LG won't disappoint. For everyone else, the Samsung QN90C is the TV to beat in 2024.
