HDMI 2.1

Why Isn't My 4k Roku Streaming in 4k?

Roku Ultra

Episode 1759

Jose from Modesto, CA

Jose got a new 4K TV and a Roku Ultra. But the Roku Ultra is getting an error for resolution. Leo says Jose needs an HDMI 2.1 cable to support the 4K stream.  You don't need a monster cable or anything like that. Just one that's HDMI 2.1 compatible. Leo recommends MonoPrice.com. It's around $12.

But shouldn't the cable that came with the Roku be compatible? Leo says it should be. Try resetting the Ultra and see if it has the latest firmware. If the problem persists, then it's likely a bad Roku unit, and you should take it back and exchange it for another one.

Scott joins Leo to talk about the new microLED technology which can use Local dimming to increase contrast with greater precision. The smaller LEDs are, the smaller the zones that brighten independently. That translates into a greater dynamic range. 

In other news ... CES is determined to hold the conference in January. Scott says he won't go because he doesn't want to be exposed to the CoVid19 virus.

Scott says that next week is the annual Consumer Electronics Show in Las Vegas, and he expects a ton of 8K TVs will be showcased. But they'll be extremely expensive and there's no real 8K content. So it'll be a while before it's worth investing in an 8K TV. The real improvement will be the new HDMI 2.1 standard. So any new TV should have that component architecture to it, and it will offer an increased bitrate of 48MBps. There will be improved low latency and variable frame rate as well. HMDI 2.1 will require new cables as well, but it will be fully backward compatible.
