Seiki 42” LED 4K UHD TV

This slim, sleek TV can showcase live television and movies in brilliant 4K Ultra HD and supports the latest HDMI and HDCP 1.4 standards to get the most out of your home theater components, such as media players and gaming consoles.

Rich, Cinematic Picture
4K Ultra HD resolution supports an almost uncannily realistic picture. 4K refers to Ultra HD’s more than 8 million pixels—about four times as many as 1080p Full HD resolution—which saturate the display so completely that images retain their lifelike detail regardless of how close or far you are from the screen. This pixel density also supports heightened picture quality for non-4K content.

Enhanced Brightness and Depth
LEDs boost brightness, creating a brilliant picture that’s easy to see whether you’re curled up for a late movie or getting ready for a noon kickoff. Striking black and white levels give images more pop, contribute to a more realistic sense of depth, and amplify shadows and other lighting effects. LEDs also consume little power, making them more energy efficient than other forms of display lighting.

HDMI and USB: Connect to More Content
An HDMI port connects high-definition components such as a Blu-ray player, cable box, or Roku Streaming Stick directly to your HDTV. USB input pushes your TV’s connectivity even further, letting you do things such as view photos or listen to music saved on thumb drives, digital cameras, and other USB sources.

Works great as a tv, but out of the box it makes a terrible pc monitor. Loads of input lag! You need to update the firmware with a usb drive to add PC Mode. After this it works good as a monitor.

Had to immediately troubleshoot input lag. Firmware update mostly resolved the problem. Keep in mind if you want to use this thing for gaming. With latest firmware, fairly usable.

Great price, very bad delay so it's bad for gaming. I'm happy with it. But most gamer buyers should look elsewhere
