Costco vs TV: Which Big-Screen Model Wins?

Costco has long been a destination for value-conscious shoppers, and its TV selection for 2026 continues that tradition. With membership pricing that often undercuts traditional retailers, Costco offers a curated mix of major brands-Samsung, LG, Sony, TCL, and Hisense-each bringing unique strengths. This guide compares five top-tier models based on real-world specs, industry benchmarks, and verified owner reviews from Costco’s website and third-party forums. No lab testing here; just honest analysis to help you choose the right big-screen TV for your home.

1. Samsung QN90D (75-inch Class Neo QLED 4K)

Why it’s here: Samsung’s 2024 flagship Neo QLED remains a top contender in 2026 due to its exceptional brightness and anti-glare technology. The QN90D uses a Mini LED backlight with precise local dimming, delivering deep blacks and vibrant colors. Owners praise its upscaling of lower-resolution content and wide viewing angles. The Tizen smart platform is snappy, and the included solar-powered remote is a nice touch. However, some note that blooming around subtitles can occur in dark scenes, and the lack of Dolby Vision may disappoint HDR purists.

2. LG C4 OLED (65-inch Class OLED evo 4K)

Why it’s here: LG’s C-series OLEDs have been a staple for cinephiles, and the C4 refines the formula with brighter panels and improved heat dissipation. Perfect blacks, infinite contrast, and wide color gamut make it ideal for dark rooms. Owners rave about gaming performance with four HDMI 2.1 ports and support for G-Sync/FreeSync. The webOS interface is user-friendly, though some find ads intrusive. Burn-in risk remains a consideration for static content, but LG’s panel care features help mitigate it.

3. Sony X95L (75-inch Class Mini LED 4K)

Why it’s here: Sony’s X95L uses Mini LED backlighting with its Cognitive Processor XR, resulting in excellent brightness and local dimming that rivals OLED in contrast. It supports Dolby Vision and IMAX Enhanced, making it a top choice for movie lovers. Owners highlight the superior motion handling and upscaling, even for 1080p content. The Google TV interface offers extensive app support, but some find it slower than competitors. The wide viewing angle layer helps in bright rooms, though black levels can wash out from extreme angles.

4. TCL QM8 (85-inch Class Mini LED 4K)

Why it’s here: TCL’s QM8 series offers an incredible value proposition with high brightness and thousands of local dimming zones for a Mini LED TV. It supports Dolby Vision, HDR10+, and has a 144Hz refresh rate, appealing to gamers. Owners appreciate the vivid picture out of the box and the low input lag. The Google TV interface is smooth, though some report occasional software bugs. The 85-inch size at this price point is a major draw, but the viewing angle is narrower than OLEDs.

5. Hisense U8N (75-inch Class Mini LED 4K)

Why it’s here: Hisense’s U8N is a strong competitor to TCL, offering a similar Mini LED setup with high peak brightness and good local dimming. It supports Dolby Vision, HDR10+, and has a 144Hz panel. Owners note that the out-of-box color accuracy is impressive, and the anti-glare screen works well in bright rooms. The VIDAA smart platform is adequate but less polished than Google TV. Some users report motion handling could be better, and the built-in speakers are mediocre.

How They Compare

How to Choose the Right TV for You

Room Lighting: For bright rooms with windows, the Samsung QN90D or TCL QM8 offer high brightness and anti-glare. For dedicated home theaters, the LG C4 OLED provides perfect blacks. Gaming: The TCL QM8 and Hisense U8N have 144Hz panels and low input lag, ideal for console and PC gaming. The LG C4 also excels with OLED response times. Content: If you watch a lot of Dolby Vision content, avoid Samsung (no Dolby Vision). Sony’s X95L offers the best upscaling for lower-quality streams. Size: Costco often stocks larger sizes at competitive prices; the 85-inch TCL QM8 is a standout for those wanting a massive screen without breaking the bank.

Costco Membership Benefits

Costco extends its generous return policy to TVs (90 days for electronics) and often includes an additional warranty through Allstate or SquareTrade. Many models come with a free 3-year warranty, and Costco’s concierge service handles claims. Additionally, Costco frequently bundles TVs with mounting services or streaming credits, adding value beyond the price tag.

The Verdict

For most households, the Samsung QN90D offers the best balance of brightness, color, and smart features, making it a versatile choice for mixed-use rooms. If you prioritize cinematic picture quality and have a controlled lighting environment, the LG C4 OLED is unbeatable. For gamers and value seekers, the TCL QM8 delivers exceptional performance per dollar. Ultimately, your decision should hinge on room brightness, content preferences, and budget.
