4K/UHD Resolution
What is 4k/UHD?
4K/UHD is on the cutting edge of screen resolution technology. This new format is quickly gaining in popularity, for obvious reasons—namely, it boasts a pixel count 4 times larger than 1080p!
With 4K Ultra HD (UHD) resolution, you'll immediately notice a viewing experience that’s more vivid and lifelike than ever before. 4K content is already available from your favorite apps like Netflix* and YouTube.
* Netflix requires a Premium subscription to stream content in 4K.
You must meet all of the following requirements to view content in 4K resolution:
Television
Your television must be compatible with 4K/UHD resolution and have it enabled. Check the instructions that came with your TV or contact the manufacturer if you aren't sure.
HDMI 2.0 and HDCP 2.2
- HDMI 2.0 is a new version of the HDMI specification, and it’s necessary for displaying 4k content from TiVo BOLT. Even if you have a 4K television, you must verify that it has an HDMI 2.0 port (most televisions label the 2.0 port to differentiate it from the “normal” HDMI ports). If you aren’t sure of your television’s HDMI specification, refer to your owner’s manual or contact the manufacturer.
- New TiVo BOLTs come with an HDMI 2.0 cable. It is very Important that you use the provided HDMI cable. HDMI 2.0 is fairly new—Even if you have an expensive HDMI cable, it won't work for 4K if it isn't HDMI 2.0.
- There's also the issue of copy-protection. HDCP 2.2 is a copy-protection standard and is critical to displaying content in 4K. If your HDMI cable is plugged into an HDMI port (or television) that does not support HDCP 2.2, you'll get an HDMI not permitted error.
- Earlier model 4K TVs were manufactured before HDCP 2.2 was released. For this reason, these televisions are incompatible with current 4K content. HDCP 2.2 also applies to every component in your HDMI signal chain, including receivers, sound bars, and other devices. Any incompatible device will trigger the HDMI not permitted error.
Content
Currently, the only content available in 4K/UHD is through Video on Demand Apps like Netflix and YouTube. However, you'll be ready when more broadcasters expand their lineups to show 4K/UHD content.
When content is available in 4K, you'll see the 4K/UHD icon:
This icon only indicates that 4K resolution is available from a video provider; you still need to have the proper TV, cables, subscription from a VOD/OTT app, and high-speed internet in order to stream 4K/UHD content.

I have a 4K television and I’m using the provided HDMI 2.0 cable. Why can’t I display 4K from my TiVo BOLT?
Not all 4K televisions are alike. Ultra HD video is still an emerging, constantly changing technology, so a 4K television built in 2014 might be limited in displaying 4K content from the TiVo BOLT. Keep the following factors in mind when determining your ability to view 4K content on your TiVo BOLT:
Emerging technology factors
- 4K TVs can have their firmware upgraded via the network. Firmware upgrades to a 4K TV might cause functionality to break.
- A 4K TV might not support and display all UHD formats, such as 4096x2160 pixels at 60 frames per second (fps).
- A 4K TV might not support the HDMI 2.0/HDCP 2.2 format that some applications on the TiVo BOLT DVR require.
- HDMI 2.0 and HDCP 2.2 might not be enabled by default on every port on the 4K TV. You will need to check which port/s are compatible.
- Methods for configuring 4K TV ports for HDMI and/or HDCP differ between manufacturers, models, and year of manufacture. This might require you to read available documentation for your product and/or research these methods via the Internet.
- Many older 4K TVs do not support all color depths.
Blank screen/unsupportable video format troubleshooting
If your TiVo BOLT is using a video output format that your TV doesn't support, you might be unable to see the screen in order to fix the problem. If this happens to you, you can reset the video output format with a remote-control shortcut. To return the BOLT to a basic 480p video format, press the following buttons on your BOLT remote:
Thumbs Up, Thumbs Down, 4, 8, 0, Clear
Now you can access to the Video Resolution settings to make sure the correct formats are enabled:
