My projector is a 1080P native projector. Right now I assume the projector is scaling/deinterlacing content from my DirecTV DVR which is a mix of 480p/720p/1080i. Based on reading the the link in batpig's response in post 9741 - it seems like our receivers have a pretty capable (if poorly marketed by Denon) video processor. Should I be using it to scale/deinterlace all content -- so it feeds the projector a nothing but 1080p signal?
If it matters -- between the AVR and the PJ -- I have a Darbee Darblet DBP-5000.
Thanks in advance!
You have three places where the up-scaling can be done, the DTV device, the 4520, and your PJ.
Starting with the DVR, if it is set to output Native mode, then it is doing no up-scaling. Otherwise, the DVR is doing the up-scaling.
Moving on to the 4520, video conversion should always be set to On, because this provides the on-screen display, such as the volume control. Next, the up-scaler can be turned on, and the max setting should be 1080p, not 1080p/24 (which, according to my experiments, results in a lower quality PQ).
And, of course, if you leave the DVR in Native, and the 4520 up-scaler off, then the PJ does the up-scaling. The only way to determine where to up-scale is to try all three, and compare the resulting PQ. If the difference is visually obvious, then choose the best one. If the difference is subtle, you may need specialized test patterns from a disk to determine which mode is best. Spears&Munsil ver 2 Blu-Ray is a good disk.
I output Native from the DVR, and up-scalet to 1080p on the 4520. For my Oppo Blu-Ray, I up-convert on the Oppo, and have up-scaling off on the 4520.
