"You may find that the "AUTO" setting in "Monitor Out" does the best job.
The 809 will then sense what it is being fed from the source and will use its internal HQV processor".
"If, on the other hand, you have a display with an excellent onboard resolution processor or a new 4k unit, "DIRECT" might be your best option available in the picture mode menu after you have set the "Monitor out" resolution to "SOURCE". Or, if the above is true, simply set the Monitor out to THROUGH and the HQV processor will be defeated."
My TV is a 2015 55" Samsung 4K SUHD JS9000. I have no 4K sources. I feed signals to the 809 from a Panasonic Blu-ray player (built-in Freeview TV terrestrial tuner and a Hard Drive), a standard Sky box, a PS4 and watch a lot of movies, in .MKV format, off portable Hard Drives plugged into a Western Digital TV Media Player. All are connected to the 809 via HDMI, except the PS4. It's HDMI goes into an input on the One-Connect Box which has it'e "HDMI UHD Color" set to ON. PS4 sound is via Optical cable to the 809, from the One-Connect Box.
Does anyone know if the upscaling in the JS9000 produces a better picture from my sources, than the upscaling chip(s) in the 809?
Now that you know what my sources are and what my TV is, if the TV will do a better job than the 809, should "DIRECT" be selected in the picture mode menu after setting the "Monitor out" resolution to "SOURCE", or, set the Monitor out to THROUGH and the HQV processor will be defeated?
I would like to get the best pictue I can, concentrating on the 1080p .MKV movies that have been taken from Blu-ray. Most of the files are in the range of 12GB to 22GB size.

PS. My 809 had it's HDMI board replaced by an Onkyo service agent 2.5 years ago and has had no problems since then. Onkyo will be on my short list when I upgrade the receiver, when 4K sources are more common. Lets hope it does not go the way 3D did. The JS9000 is a 3D TV and I like 3D!
