5080HD and Comcast - How to Calibrate

Ok,

So i got my 5080HD a few days ago and have to say that i'm not that impressed w/ the Out of the Box settings. I tend to leave it on Optimum but find the colors are almost always over the top. I can't find a happy medium. I donated to the GetGrey people and have received their Disc. I popped it in my standard DVD player and calibrated just the contrast/brightness and it has helped some for watching SD DVD from that device. I'm still waiting on my blue filter to calibrate the color. I've tried D-Nice's settings but find them too dark and muttled...at least the references settings...

Anyways, I was wondering..how the heck do you calibrate your Comcast HD Box when it doesnt have a DVD Player? I have the Scientific Atlanta Box. Does anyone have settings for this?

Thanks for your insight!

If you calibrate a DVI/HDMI input on your display using your DVD player, that port will be effectively calibrated for a Moto STB.

So if i plug in my DVD Player and use the GetGrey Disc to Calibrate, say, HDMI Port 4, then I plug in my Xbox360 to that same port, it will retain those calibration settings?

Also, it's the Scientific Atlanta Cable Box and not Motorola.

And one more thing, I was under the impression that each source requires it's own individual calibration... Is this something to consider?

thank you!

New 5080HD owner here too and I could be wrong but.. I thought that the D-Nice reference settings were only suggested settings once the set had 150-200 hours on it.

Someone please correct me here if the above is not accurate.

Yes.

As long as both your DVD player and the SA box use "video" standard digital outputs (16-235) instead of PC standard (0-255) the calibration will be accurate.

I have no idea what standard the XBox uses; perhaps someone else will chime in.

As long as all the devices you plug into a given digital input (DVI/HDMI) use the same output standard (video or PC) the calibration will be accurate.

Analog (component) devices must be calibrated individually!!

For your HD STB, you can also use the test pattern broadcast by HD-NET at some ungodly hour on weekends. Check your listings and schedule your DVR to record them.

Thanks for the quick and informative reply, as always.

Im not sure what std the xbox uses but it does have a DVD player so I can play the calibration DVD (GetGrey) on it and get a good start there. If anyone has settings for their 5080HD and an Xbox 360 over HDMI that would be greatly greatly appreciated!

Currently my DVD player uses Analog (component) out and isnt even progressive scan, so i'll be upgrading that shortly. Looks like i'll have to use my xbox to calibrate the HDMI port for my Cable box. Does this sound like i'm on the right track?

So should i just use D-Nice's settings for both of my HDMI devices (Xbox and Cable box?)

Thanks!

I'm afraid I don't know what "D-Nice" is but as long as the issues mentioned in my last post are followed you shouldn't have a problem.

"Progressive" output and "upscaling" are generally marketing bumph!! Don't spend your money quickly ... what you have may work just fine!!

Read the link in my sig.

Yes, you are correct. D-Nice's settings should be used and instructions followed.

Those with new Pioneers should read the "Official Pioneer 8G settings" sticky above.

I did read it....most of it....it's just...well...it's a hundred pages long.

I was trying to ask a more specific question but I guess it's more generic then I envisioned it to be. Thanks for the advice everyone.

Yes, it is long but a good read if you have a few days. Definately information overload. Pick a slow day at work.

You want your display to be a little dark for the first 100-150 hours of use or to speed things up, you could download the break-in DVD. I kept my setting a little dark for the first couple of weeks and then gradually moved them to the desired levels. I would definately buy a new upscaling DVD player or blu-ray because they upscale standard DVDs.

So what!?

How is that goiing to improve the PQ??

Your 5080HD is a bastard 1365x768 resolution!

It will "upscale" a standard DVD 480i signal to its native 1365x768 resolution just fine just like it already does with EVERY signal you send it.

Using an "upscaling" DVD player is a complete waste of time. What are you going to upscale the DVD signal to?? 480p 720p? 1080i? 1080p??

The 5080HD is just going to have to RESCALE whatever you set it to anyway.

Now the image is being rescaled TWICE. Do you have a clue what that does to the PQ?? Run some test patterns and see.

The cardinal rule about scaling is that IF YOU HAVE TO SCALE AT ALL, DO IT ONLY ONCE!

You're new around here, I see (despite the 3K+ posts). Love him or loathe him, D-Nice has a very large footprint on this plasma forum, particularly with issues related to Pioneer and calibration tips. I guess he's "semi-retired" from the forum, but nevertheless, you'll be reading his name quite a lot should you hang around here much.

What one can detect (and consider a catastrophe) via test patterns is often quite different than real world viewing from typical viewing distances, regardless of once or twice or zero times scaling. In other words, much adieu about not a whole lot.

In any case, welcome to this side of the forum. Many contentious good times ahead, I predict.

Oops!

I didn't realize that I was in a small screen forum.

I guess they left the door open back in the front projection forum. I guess I'd better be wandering back there before they miss me.
