The Hopper3 outputs 1080i unless the content requires 1080P or 2160P (4K)
The Plus and the Joey4s upscale all content to 2160P, and also flag the content as HDR regardless of the actual color profile. How the TV will handle that depends on the HDMI setting.
So, it's possible that the difference you are seeing is related to the upscaling performance, or the possible HDR settings on your TV.
This information makes me want to try a Plus or Joey4 on my newer 77 Sony oled to see if the picture is better.
I wonder if the Wireless Joey 4 will output to my 32 inch QHD (2K) computer monitor?
I once hooked up an Apple TV box to my computer monitor and it worked I think.
I don't know what resolution the Apple TV was sending to the computer monitor.
I'm very pleased with the picture from the Joey4 on my TV.
The satellite channels picture quality from the Hopper 3 on my newer 77 Sony oled could be better.
Perhaps the satellite channels being output 1080i?
Maybe it is the large screen size?
I am not sure why the picture seems a little less good from the Hopper 3 on my newer 77 Sony oled?
I have tried the Joey4 on an older 43 inch 4K LG non oled that doesn't do HDR.
Joey4 is great!!!
Can't wait to get the Wireless Joey 4.
Maybe a Plus or Joey4 newer would look better on my 77 inch TV?
Thank you for your help.
