4k?

Post by SpencerC »

I use my HDHomeRun Prime with cable card for my computer. Does it support 4k resolution if I had 4k monitors?

The simple answer is yes. However there are two parts of that, the first is the HDHR itself. The tuner itself does not care what resolution the video stream is as long as such is available and can even support 8K and higher (in theory). Thus the prime dos support 4K video. However typically you will not find 4K signals with the prime as providers don't make such available. Verizon is your best bet for such on occasion but DRM on 4K streams such as with this years olympics was a problem on some client devices. Most other providers use iptv to deliver 4K streams thus the prime won't tune them as it won't have access to them.

The next part is the client which is what displays it on your tv/monitor. An android 4K box is "designed" for 4K thus will support 4K content... it even worked well for 4K DRM content (assuming display also supported the higher hdcp requirements, but currently there is an issue with DRM for many with the android client until there is an update. Windows can be hit or miss depending on codec support (HEVC would usually be the codec for 4K content). I also have occasionally seen not filling the screen when set at 4K when the stream is usually 1080p or less (but often zoom works and/or a native resolution is picked depends on what is being used to view). Also keep in mind that DRM requires HDCP and for 4K you need both the "card" and monitor to support the appropriate level of HDCP for 4K content. Many had issue with windows pc's and the olympics with verizon as they put DRM on the streams this year and many didn't have the appropriate things pc side to support 4K HEVC with DRM, where it had worked fine on the same machines with non-drm content... keep in mind codecs have to be official for DRM and HDCP is required.

Personally since I have never been able to get 4K streams, I prefer to set output lower and let the tv/monitor handle such as most do an excellent job but some don't handle such well (again going back to possibly not filling the screen).
