What to Watch in 4K on Your Ultra HD TV: Netflix, YouTube, and Top Sources

4K TVs made fantastic holiday gifts last Christmas, and with setup complete, it's time to dive into true Ultra HD viewing. But what 4K content is actually available? The ecosystem is growing, though you'll need to know where to look. As experienced tech reviewers, we've rounded up the best options for you.

A Quick Primer on 4K and Ultra HD

Let's clarify key terms before diving in. 4K and Ultra HD (UHD) are often used interchangeably, though technically distinct. True 4K resolution is 4096 × 2160 pixels, while UHD is 3840 × 2160—slightly narrower but practically identical on consumer screens. Both far surpass 1080p HD, also known as 2160p for UHD.

Professionals use 4K for production (around 4000 horizontal pixels), while UHD is the consumer broadcast standard. In everyday use, treat them as the same. Note: Some services require specific TV chipsets for UHD playback—always verify with your manufacturer.

Netflix

Netflix leads with robust 4K support, featuring hits like House of Cards and Breaking Bad, plus ongoing additions such as Star Trek: Into Darkness.

Ensure compatibility: Check Netflix's device support guide for your TV model. You'll also need 25 Mbps+ internet and the Premium plan at $11.99 (£8.99)/month.
