PROS

  • The Visio P502ui-B1 provides excellent contrast for an LCD TV and deep black levels.
  • The TV offers second-screen interactivity, which means you can use your smartphone to control the TV's smart features.
  • The low input lag makes this TV a good choice for gamers.

CONS

  • You'll find better color and more natural images on other 4K TVs--especially before you calibrate the P502ui-B1.
  • The P502ui-B1 is "hyperactive" when it comes to video processing--light flow, detail, and edge enhancement can be too much.
  • This TV is thicker than many LCD TVs, partly because of the direct LED backlight.
When Vizio's P502ui-B1 first debuted, it was plagued with overly aggressive video processing; the picture looked too sharp and often had twinkly artifacts. Vizio dropped a firmware update in early 2015 to address most of the problematic picture issues, but even with those picture issues, this 4K LED TV has a lot to offer, including excellent contrast, deep black levels, and low input lag, which makes it perfect for gaming. Plus, it's one of the cheapest 50-inch 4K TVs on the market.

The TV has incredibly low input lag in the Game Mode and we do not hesitate to recommend this model as a gaming TV.

I watched the first few chapters of The Hobbit (upscaled from 1080p) and was impressed by the absolute black of that film's letterbox bars at the top and bottom of the screen.

As we mentioned at the top, the best thing about the P series picture is its contrast -- at least on every size but the 55-incher.

Let’s be clear, upscaled 720p content on a 4K TV still looks good. But when you’re constantly switching between watching something in 4K and content upscaled from 720p, the drop-off is impossible to ignore.

One more picture quality complaint: edge enhancement. Even with the set’s Sharpness control set to zero, both test patterns and many types of real-world content displayed faint white lines on object edges, particularly ones with abrupt dark-to-light transitions.
