Cinema mode

Bold = Changed values from default

Contrast = 80
Brightness = 52
Color = 50
Tint = 50
Sharpness = 0
Lamp = High
Gamma = Off
Black Enhancment = Off
Iris = Auto 1 / Recommended
Color Temp = LOW
Color Mode = WIDE

*update*

PLEASE DON"T GO INTO THE SERVICE MENU UNLESS YOU KNOW WHAT YOU ARE DOING - IF YOU PLAY WITH OTHER THINGS IN THE SERVICE MENU YOU MAY NOT BE ABLE TO PUT THE SETTINGS BACK PROPERLY! GO INTO THE MENU AT YOUR OWN RISK!

Color Uniformity - LONG VERSION (BEST)

For those willing to try to fix color uniformity themselves by eye

Whats needed?

DVD or External Video Proccessor with full frame IRE Steps

service menu

Gamma menu

There are 12 full frame steps - with 300 points of correction on each

Green is usually set to 0 for almost everything.

I made my adj to green as to keep things simple.


Here is the list of the Internal Full Frame Steps that effect the External Full Frame IRE settings

0 = 0 IRE
1 = 5 IRE
2 = 10 IRE
3 = 20 IRE
4 = 30 IRE
5 = 40/50 IRE
6 = 60/70 IRE
7 = 70/80/90 IRE
8 = 100 IRE
9-12 = Apparently more then 100 IRE with my settings - So I am not touching these.

* I believe these are closely related to CONTRAST you have set. I have mine at default 80 - If I were to bring contrast up to max I would raise my white levels allowing me to use 9-12. I also think this would change the relationship above, but if you fix it, it will be fixed even if you change the scale.

Color Uniformity - QUICK VERSION (can minimize it not eliminate it)

For color uniformity problems with slight green shift

You can minimize by accessing

Panel Driver
Green = 85 (this is the default value on mine)

For color uniformity problems with slight red shift

You can minimize by accessing

Panel Driver
red = 85 (this is the default value on mine)

For color uniformity problems with slight blue shift

You can minimize by accessing

Panel Driver
blue = 37 (this is the default value on mine)

Uping the Blue Minimized the Green blob/push too

- I am now doing this the long way, and it is alot better as you could completly eliminate it with the right tools. You can greatly correct by eye too.

*****************************************************

Some Users settings for color temp

Can you turn off colors, i.e. Red only / Green only / Blue only modes for color calibration?

Yes, it is out of the box close to D65 Standard.

Also you may be slightly crushing blacks at 49 brightness.

If you bring up a SD DVD that has a THX Video Calibration - can you see any of the THX drop shadow?

if not you should bring it up to a point were you can just about see it. other wise you are losing some black details.

With your calibration settings, do you have enough brightness for ambient light viewing?

Byte - I loved your settings for the HS51a, are you going to be getting the Pearl?

Please tell me yes!

Sowk,
I used your setting and they seem to be really accurate. I have not really set my projector up yet, but have been playing dvd's thru the component hookup and i have to say this projector looks absolutely amazing. So smooth and film like would be the way i would describe it. As far as setting I want to know if anyone has gone into the secondary color setting(rcp i think its called) and tweaked the colors to better resemble the ruby. Not sure how many people actually have both projectors, but im sure someone will have some tweaks soon.

How are you guys calibrating contrast? In avia I usually look for white clipping on the moving white bars, but here I can crank contrast to 100 and still see the details. Just looking for some tips.

Do you see any "sparklies" when watching TV/movies or playing video games with a Silver Star? This is the screen I really want for the Pearl, but am terrified of the sparkle effect.

Movieguy...

When you push the master contrast up, watch for any color shifts. On some other Sony projects using the auto iris, the video processing portion of the process seems to get maxed out and color shift at a certain value. On the HS-51A, as I moved abve 96 contrast, I saw dramatic grayscale tracking color shifts, so I used a contrast setting of 95 and then calibrated my RGB gain/bias settings. You would not think it would make a difference, that the RGB and master contrast are link proportionally. However, I found choosing contrast of 95 over 80, tamed some of the red push inherent in the projectors video processing under auto iris.

I have not played with the Ruby or the Pearl, so maybe someone else can chime in.

If you have the time, maybe you could calibrate at contrast 80 and 95, and then see if you notice any differences.

IIRC gregr of WSR stated that one should calibrate the Ruby at contrast 80. It is likely the same for the Pearl.

fear not!

I could see the sparklies the first few days I had mine, but after that it was pure image enjoyment. Of the five other screens I have, hands down this is the one I enjoy watching the most.

I want to go to a 14' wide 2.35 screen. I dread having to switch from the Silver Star surface to something else. The High Power material is the next best thing to me.

PM me if you are interested in a SS

Thanks Bytehoven and HoustonHoyaFan. I appriciate the information. I'm a little suprised I'm only getting 500 lumens at close to max zoom with high lamp mode on. If I crank my contrast up to max I get about 650, but my numbers seem lower than those others have measured. I use Avia to calibrate and dont have any equipment to do any real color calibration, but the colors do seem to shift a little when I crank contrast up so I think the default of 80 may be good to stick with.

Normally, I'd write the lower light output off as just differences in measurement, placement, room, etc., but that combined with a smell I get from the projector (like a hot bulb or electronics) makes me a little nervous. Never had that happen before. On the other hand, the image is stunning so I'm thinking the smell is just because the projector is new. . I'll just keep an eye on it and see what happens.

I have Steve Smallcombe's SMART calibration system with a professional light meter, but I don't have the spreadsheets that one would need, in order to calibrate my Pearl. (For those that are unfamiliar, his is a system based on using a professional light meter, some filters, and a bunch of calculations done in a spreadsheet that is specially created for each projector, taking into account what can be adjusted on each projector.)

I have a $40 light meter that I bought online. I recognize my meter may be off or there could be any number of reasons for the differences in measurements.

The smell is a little different from that of new electronics that you buy. I thought it might go away after 6 or seven hours on the projector, but it is still there. I would expect if there is a problem it will menifest itself over time. If its abad bulb or something, that will be pretty easy to spot as I use the projector. Right now I have no complaints with the picture, so its no big deal.

This is my third projector and I've never had that happen before so thats the only reason I am a little concerned about the smell.

Mine smells a bit, as well, especially it I put my nose up to the exhaust in the front, but after say 10 hours, it greatly diminished.

After 10 hours with your nose to an exhaust port the smell had better be greatly diminished.
