The 120Hz also divides into 24 evenly, so that there isn't additional pulldown processing.
Does this TV support 1080p24?

With two sets A500 and now an A630, I have been struggling with a green cast when white light in scenes alters due to movement or shadow, especially night footage. The people at OPPO had me manually signal down to 480p at DVD and observe color quality. Green cast was reduced from when unit was at 1080p. Noticably. According to them, that result establishes that display unit does not properly process BTU.709, instead is doing signal processing to BTU.601. Neither term means anything to me. I am then told to consult my manual to change BTU colorspace settings. sheesh!
What are they talking about? More importantly, what do I need to do to eliminate the greening of displayed elements on the A630?
Sorry to hear you're having trouble with your set.
Who is OPPO? I'm sorry, that's not a term I'm familiar with.
If this is just happening in your DVD input, I wouldn't adjust anything until you know for sure if it's the television or the DVD player. Does it happen on other televisions the same way?
Thanks for picking up.
OPPO makes DVD players and HDMI switchers. OPPO Digital is the full name I think. I just bought one of thier well regarded players, DV-980H that uses a customized Mediatek (sp?) vid-on-a-chip. The change in PQ when sent 480p vs 1080p to display was notable, Samsung display liked the colors much better when sent at 480p.
I suspect that if I "solve" every issue that OPPO says might be the displays inability to signal process BTU.701, then they will up-sell me to the Faroudja based DV-981 or the ABT DV-983. grrr. In your experience is there a "better" choice for vid chipsets going to Samsung LCDs? Mediatek, Faroudja or some (none $$$$$) option?
I did some looking into those units, just to make sure I had my facts straight. Thanks for your patience.
Really, picture quality is subjective. We've had some good success in the past with Faroudja, and I thought the difference was notable in the upconverting DVD players, but I'm just not up to speed with processors transferring an HD signal. I'd really have to see them side by side before I could even offer my opinion on which processor is the best - and then, it's still.. just.. my opinion. But I plan on doing just that this year at the iCES Show in January if they offer a comparison. I'm never supposed to champion one over the other - particularly my opinion on other product lines or companies, but I'm certainly entitled to my opinion in a non-suggestive, thread-participating way. I just don't have one.
It's interesting that a 480p signal looked better than the 1080p signal. That's where I'm baffled. But again, that's a perfect example of where a subjective opinion can't be classified as a final "wrong" or "right" or "best" or "worse" way to do it. A textbook analysis would likey suggest the opposite, and in real world application, it's not that way.
Let's open this up to discussion - does anyone have a favorite flavor of vid-on-a-chip technology?
Thanks for continuing to look into this.
The PQ matter that was improved when DVD player was downshifted to output 480 was the color trueness. i.e. the picture lost much of the green glow that seemed present at higher (up to 1080p) outputs. This is what the techs at OPPO say establishes display is not processing BTU.709 signal.
Have you been able to confirm the signal processing of the model 630? Someone in-house ought to be able to give an answer to that.
Please have another go at this.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
