Questions for other Sharp 10000 Owners

I have a Motorola HDD 200 High Def decoder for receiving Cox Cable high definition material. I can hook it to the Sharp 10000 several ways. I'm wondering what theoretically would be the best as I see little difference in the various setup options. I can switch the decoder for 5 wire RGB or 3 wire component output. Also, I can switch the decoder output from "native" to 480P to 720P or 1080I.

I have been using the 3 wire component output as this allows full color and tint control on the Sharp 10000 (when you input RGB these controls are bypassed). I've also experimented with 720P vs 1080I output from the decoder into the Sharp 10000. Greg Rogers in his review thought the 1080I deinterlacing was great. To my eye, both 720P and 1080I look great, however I think I see a little more artifacting with the 1080I output than 720P. Also, 720P allows me to bypass the internal scaler of the Sharp in the "dot to dot" mode which I think looks the best. I'm just curious how others have their Sharp 10000 connected and what your experience has been with High Def.

Lastly, has anyone noted "color fringing" or what almost looks like convergence error on the Sharp 10000? What I mean is when looking at the setup menus for the sharp. In the right upper corner, I see a little green to the left and a little red to the right of bright white lines. Another test is stand next to the screen and hit an input button. When the input is displayed in the upper right hand corner, again I see a little color fringing. This is absolutely not noticeable at normal viewing distance, and seems to be

I use the hdd200 with my 4dtv Satellite system for HD. I run it in 5 wire rgbhv with "native" selected for resolution. I think it looks best there. As I'm sure you know..don't let the hdd200 do any upconveting of SD channels as it does a horible job imo, and the sharp internal scaler is much better.

I haven't noticed any convergence issues with mine.

mooneycj - currently I'm running 3 wire component. I haven't noticed any color fringing whatsoever. I've mainly been watching HD via Comcast Digital Motrola DTC5100 and my DVD player.

Both of the Z10000's I've had as well as the Z90 had the green fringe/red fringe thing. I wouldn't worry about it.

If your cable box allows you to do native output, you should use that. That means the signal will be sent in its native format (480i/720p/1080i) and the projector will do the deinterlacing/scaling. If you set the cable box to one resolution, then it will do any up/downconversion, and I'd bet money that the projector will do a better job.

Thanks for the tips guys. Cbander and thirdkind, I will switch to "native" output on the decoder box, this does make sense. I agree that the "upconversion" of the decoder of SD stuff is marginal at best. I've hooked up the 5 wire RGBHV from the decoder to the projector. I can toggle a switch on the back of the decoder to see which is better. My initial impression is that there is no significant difference, however using the 3 wire component allows more control of color and tint on the Sharp projector so I think I will use it that way.

I did a little more experimentation re: color fringing. I think I'm seeing an artifact due to my setup. My screen is centered on the front wall. However, the projector is not quite centered on the back wall having to be offset about 1-2 inchs to get the proper attachment of the ceiling mount to the studs. Therefore, there is a very slight skew of the projector to get the projected image fully on the screen. I think this is what is causing the color fringing. I may try to shim the mount a bit to completely center the projector. Thanks. Corey J

I just had Kevin Miller of ISF fame, come calibrate my Z10k this weekend. If you don't have your proj. calibrated, the DVI or RGB "may" look better than component output. However, with a calibrated unit, the component looks MUCH better than either of the other outputs because of the precise calibration of what has been discussed. I use the Sony HD200 and keep it set at 1080i as I have seen little difference utilizing anything else really. The problem with my setup is the Dot by Dot does not fill the screen.

As an aside, any of you Sharp 10k owners that have Avia, please try something for me. Get the disc go under the advanced setup and then I think its video adjustments or something similar then select Widescreen Enhanced, then the 100 IRE Crosshatch pattern.

Does your projector cut off the left and right sides of the circles on the perimeter?

Nic - I'll try your test pattern tonight and let you know. Regarding Dot by Dot mode - others had previously mentioned they had perfect 1:1 pixel mapping in this mode with no problems - I wonder if there could be something wrong with your sync settings.

LovingDVD,

You got me man! It's so bizarre, its like picture within a picture on my screen. Any thoughts or suggestions to resolve this?

Sorry Nic but I'm not too familiar with these aspects of the pj as I currently do not have a HTPC or external scaler that I'd use the dot by dot mode in. Try searching some of the older Sharp 10000 threads - there were some mentions from forum members confirming everything worked great as far as 1:1 pixel mapping goes and perhaps they can shed some light on this for you.

NKUEHN,

Could you share some of the details (settings) from your recent calibration, as well as your environment (screen, lighting, etc.)

I will check my Avia test tonight, however I seem to remember circle pattersn only showing half on each side

I have an rp-82 fed into the Z10K. The dvd is set on the darker mode (which I understand is different than the lighter setting on the Auto 1 mode as noted in the DVD shootout).

I want to point out for those who have this projector, and those who are looking that this projector out of the box is closer to the 6500K then any other projector out there now. Kevin Miller of ISF fame has worked with all the current must have projectors. The grayscale was uniform across the board at about 200-300 degrees low at the factory 6500K setting. a few very minor tweaks to the gamma curves and it was golden.

The basic settings were pretty damn close as well, give or take a few.

Without calibration, I highly recommend the RGB or DVI output. However with calibration you will see a better picture thru component due to the finite adjusments.

The room is totally black and the ft-lamberts was 15 on a 100" FH screen.

Hope that helps.

Guys:

As promised, I'll try to post my calibration settings tonight.

Nic:

As far as the picturing being cut off, I believe I had that problem when my calibrator was doing his stuff with AVIA. He did quite a bit of "Fine Sync" adjusting to deal with that and with overscan. He really did a great job adjusting the picture. Curiously, the sync settings were a little different depending on the source (e.g. DVD was different from High Def television).
