Dim HDR and Dolby vision picture quality
I recently bought the roku ultra 2020, I discovered when I watch HDR10 or Dolby vision content, it is very dim and has low brightness in netflix, apple tv and amazon content. I compared to my nvidia ...

Remember that Roku isn't the manufacturer of the TV, so issues such as green screen is out of their control.
But I agree Roku tech support has virtually disappeared during COVID. There's not much the forum admins can do to help if there's no tech they can reach out to. I know they try, but there's stuff that only a tech can help with.

There must have been some confusion. The Roku actually green screened and then rebooted. It also locked up and rebooted several times while setting in menus. I've had the device for 3 full days and if has rebooted at least 4 times each day that I have used it. That and the dim HDR and Dolby Vision are why I am returning the unit.
If the new unit is dim with HDR and Dolby Vision I will return the replacement and purchase another brand.
Sorry, I thought you had a TCL Roku TV. Mixing up the different posts.
The new Roku is also dim. That is a shame.
I have issued a return on the device and will send it back.
Looks like I will be going with an Nvidia Shield Pro instead.
I can't play my UHD rips with my 4800, as the Ethernet connection isn't fast enough. But I watched some 4K/Dolby Vision on both Disney+ and Vudu, and I can't say the image is dim. I can start playing my UHD rips (which are HDR, not DV), and while it's not watchable because of the buffering I can see enough that again they don't seem dim. I also have some test videos (which naturally are designed to highlight 4K/HDR to the maximum) and again bright scenes are as bright as I expect.
One thing I've noticed with 4K TVs, is that they are very sensitive to their settings, especially for HDR content. Internal apps may not be using the same settings, and switching to HDR or Dolby Vision may enable different settings that need to be adjusted on the fly. I would suggest playing with the TV settings while playing HDR or DV content, and you might discover the reason for the less than stellar image quality.
