    Fair point. There are likely pros and cons of each.

    I suppose that's possible, I'd prefer to let the X1 Extreme chip in my Sony do the upscaling as it's considered very good at this, but I don't know how HEVC plays into it and whether decompressing and upscaling it can be optimized in the C61K (I'd assume the former, but not necessarily the later).

    I'm not saying the C61K is doing a better job of upscaling, just that it definitely has the opportunity to do so. Whether the advantage of having the compressed stream to work with can outweigh the processing ability of a higher end TV or AVR...I have no idea. But it should at least be considered, now that we have two people reporting a better picture on HD channels with a C61K than the HR54.

    Of course it is possible the C61K simply outputs a brighter, or more saturated, or whatever picture than the HR54 and some people prefer that - then the picture wouldn't be "better", just different in a way some people subjectively prefer.

    I'm a little confused. If I want my LG OLED TV to do the upscaling, which resolutions on my DTV receiver should I check, and should Native be turned off or on?

    All resolutions checked. Native set to on.

    I never check the 480 boxes. You don't want to send that to your TV. The lowest I check is the 720p.
    Also, with Native set to ON, that is one more resolution for your TV to check before it is finished negotiating with the Receiver. For some reason that appears to slow down the channel change on my setups.

    On my LG OLED, Native "On" REALLY slows down the changing of channels.

    because your TV is adjusting to the signal change. Assuming your display does a better job of scaling/interlacing (which is generally true), this is just something you have to put up with if you want better quality.

    The fastest way to change channels is by entering the channel number on your DIRECTV remote followed by pressing the ENTER button.

    Check the resolutions settings and see if the 480 boxes are checked. If so, uncheck them.

    There are only a few 480 channels - most of which are infomercial channels - so I doubt he’s clicking through those.

    Does not matter if there is zero channels. If the box is checked the receiver will cycle thru that resolution and try it with the TV. This slows everything down, some.

    No, it won’t. That’s not how it works. At all.

    480 will only be sent if 480 is checked and a broadcast is 480 (and native is on or native is off and no higher resolutions are checked)

    If 480 and 720 are checked, and a 720 broadcast is tuned to, (and assuming native is on or native is off and there are no higher resolutions checked) then 720 will be sent to the display.

    Extrapolate to 1080 and 2160...

    Watch the resolution lights on your receiver. It shows how many it uses. I only have 720p and 1080i checked and my resolution lights just bounce from one to the other.
    If I check them all it cycles thru the 480i, 480p, 720p, 1080i and the 1080p.
