(FORCED is just like AUTO, but also works even if the TV fails to properly publish that it can accept 4K during the HDMI handshake -- a problem that has been seen with some projectors.)
Second, yes your 4K display needs to have the video upscaled to 4K before it can light up the pixels, because its matrix of pixels is 4K. If the video was not upscaled, you'd get just a small image in the middle of the screen.
Third, there's no easy way to predict whether the 4K upscaling in the TV itself will produce better results than the 4K upscaling in the OPPO. Pretty much, you just have to try it and see if you can spot a difference. If you CAN'T spot a difference, turn 4K Output OFF in the OPPO and let the TV do it, because that puts less bandwidth on the HDMI cable, meaning you are less likely to have occasional HDMI handshake problems.
One reason it might be better to have the TV do the upscaling is that processing video which is already 4K takes extra horsepower, and so your TV may not offer as much or as good processing for 4K input compared to 1080p input. One reason it might be better to have the OPPO do it is that your TV maker may have decided to save cost on their 4K upscaling solution. Again, this is why you just have to try it and see for yourself.
Fourth, as for DVD 24p Conversion: Not all DVDs are suitable candidates for this. If you watch primarily newer movies sold on newer SD-DVD discs then DVD 24p Conversion should work well for you. If you watch older movies sold on older discs, or if you watch "live" events recorded on disc, or if you watch TV shows recorded on disc then there will likely not be a /24 frame rate stream to recover. For instance live video is recorded at either 30 or 60 frames per second. There's no safe way to reduce that to 24 -- no way to know which frames you can safely discard. And so you will see "frame drop stutter" -- a distinct jerkiness of motion most easily seen when the video pans around.
DVD 24p Conversion does not attempt to figure out whether the SD-DVD you are playing is suitable for 24p Conversion or not. It just does it. So what to do?
One approach is to just leave DVD 24p Conversion turned OFF all the time and not be bothered. The other approach is to use DVD 24p Conversion (if you think your movie SD-DVD will likely be suitable), but keep an eye out for "frame drop stutter" while it is playing. If you see the stutter, that simply means this is not a good disc to use with Conversion -- so turn it OFF! You can turn DVD 24p Conversion On or Off "on the fly" - while the disc continues playing.
Bob Pariseau, thanks. After reading your descriptions (thank you VERY much for going into such detail) I looked a little closer at OPPO's descriptions for each setting.
For Output Resolution
(Choose the output resolution that best matches your TV), I went with 4Kx2K
, because my 850C is 4K.
For 1080p24 Output
(Set 1080p 24Hz output options--for 1080p output resolution only
), I chose Off
, because I chose 4Kx2K (not 1080p) as the output resolution. Also, I don't like the idea of switching back and forth for "newer discs," which seem to play fine at the higher frame rates.
I chose Auto
for 4Kx2K Output
(Set 4Kx2K video output option). But that setting seems a little redundant, since I already told the player my set accepts 4K in the Output Resolution
setting. Would that be correct? Or, is 4Kx2K Output
independent of Output Resolution
? That doesn't seem right...so, maybe I just misunderstood something.
What makes these settings such a difficult decision for me, is that I've heard positives for both Sony and OPPO in terms of their upscaling qualities. And, I had also heard that shoving 4K into a TV that already upscales to 4K may do more harm than good.
Anyway, watching Samsara disc right now...looks super
. Thank you, very much!
