|
|
Hey Guys,
New to the forum. recently purchased and Sony G70 with 1100 hours on it. Thanx to Curt, the projector is up and running and installed on the ceiling. Using a Stewart 90" Studiotek 130 filmscreen.
I had a D50 installed prior and was setup 10 years ago when my eye sight was far better than today. LOL
I'm having issues converging and focusing.
Is there anyone in Southern Ontario, who is familiar with CRT's who could possibly set this Projector up for me???? Willing to pay of course!!!
I'm located just North of Barrie Ontario.
Any assistance would be greatly appreciated,

I could help you with that.
Will this be a set up from scratch? What sources do you have and will you be using a scaler?

The projector has been installed on the Ceiling, measured to the screen . Square and level.
HDMI Moome card installed and will be using a external Framemeister scaler through HDMI.
The Projector has been reset to 128 across all adjustments.

It sounds like you have the first part dialed in with the square and level.
Are you a gamer? Just wondering because of your selection of scaler.
What sources will you be running into the scaler?

No gaming for me. My son has a serious gaming console collection. The framemeister will be accepting 240P inputs from most of the consoles. Its actually an interesting scaler, basically made for Retro gamers.
Ill be using the Component input at 720p for sports and the odd movie. Blue ray or Sat. But once this projector is setup, im sure ill never get to use it!!!! LOL

well make sure he turns off tool bars whenever possible and doesn't decide to go skating or whatever while leaving the start screen up static. unless you want those things permanently on the Phosphor
720P on an 8" machine is still a fantastic picture, especially withva color corrected LC machine

You're only seeing 44% of the 1080p pixels when running at 720p.
Good luck!

Having tried all the way up to 1080p 72hz and 1080i 96 I still run mine at 720p 60hz. IMO I get better grey-scale, gamma, and color.
Don't base what looks best with static images like desktops and grids. Throw in some of your favorite movies and use that to make you determination on what resolution to run.

Thank you,
720P was my first option, 1080I may look better for movies. I see myself watching more sports...Hockey and Football when I get a chance to use it. It will be used for Retro gaming more than anything.

That's odd. Those 3 things are completely independant from resolution. Did you re-calibrate those 3 things at all of the resolutions you tried?
Kal |
Yes calibrate, although 1080p 72hz I only briefly toyed with, I was starting to get digital artifacts (sparkle).
Independent, not entirely. If you run near the limit of the machines bandwidth or beyond you will struggle to dial them in. High scan rate, less time exciting the phosphor and the image stats to loose some punch.

similar results here, 1080i 60hz was jail-bar city, but they were horizontal Never tried 1080i 96 but 720p looks a lot better than 1080P

When are you planning to do the setup on this?

I attempted the calibration again myself. Still in need of some tweaking beyond my eye sights ability.
I have noticed now that I have wear showing on the surface of my screen material. Its a Stewart Studiotek 130 filmscreen.
I think it had been rolled up in the tube for too long. Ive ordered new screen material, should receive it shortly.
Ive spoken to a IFS/THX calibrator who is willing to assist in the calibration. I should have more progress info in a few weeks.
thank you,

Don't confuse setup with calibration.
In your original post you asked about setup, which is:
- mechanical install (right throw distance)
- lens toe-in
- geometry
- zone / point convergence
- raster centering
- focus
- etc
Those things have nothing to do with calibration. Calibration assumes all of the above is done correctly and you have a perfectly working projector. Calibration is adjusting greyscale, gamma, and colour.
Note that some calibrators *will* do a CRT projector setup too but best to confirm exactly what you're getting. Especially these days as CRT projectors are getting to be very rare.
If the projector's not ceiling mounted that in itself can be half a day's work. If the projector *IS* ceiling mounted and the person doing it wasn't sure of what they're doing or followed the manufacturer recommendations then it's probably not installed correctly and will need to be moved (usually closer) for optimal setup.

Sorry, poor choice of words.
The projector is installed on the ceiling and its bang on IMO.
Ive asked him to set it up from there and then complete the calibration, either IFS or THX specs.

Forgot to mention:

I'm assuming you mean ISF and not IFS.
ISF and THX are not specifications. You can't calibrate to either.
ISF (Imaging Science Foundation) is a 'club' that calibrators can pay big bucks to join. Like a union of sorts. They offer pay calibration courses. They've been coming under lots of fire over the years for not doing much to push calibration for those paying the licensing fees to be part of the club.
THX (Tomlinson Holman eXperiment) was started in 1983 by George Lucas to get theaters to look and sound better. Manufacturers pay big bucks to have a THX logo affixed to their equipment/software. The logo doesn't mean it's better, it simply means they meet certain standards, like a quality assurance program. Over the years however they've come under fire for licensing just about anything and some will say it's just a money grab now.
If someone tells you they're "calibrating" to either either one, they're either ignorant about calibration (run away) or pushing these marketing terms because they think *you* think they mean something.  What's important to know is that you pay through the nose to have either logo on a calibration report, but it doesn't actually "do" anything - it's a warm and fuzzy because consumers recognize the logos.
Unless you're running something very non-standard, the only spec you should be calibrating to is Rec.709 (HDTV). That's an actual specification.
For more info, see the calibration guide I wrote here: https://www.curtpalme.com/forum_archived/viewtopic.php@t=35322.html
Make sure the calibrator is familiar with the Sony G70 projector. Very few are. If you want, mention who it is.
Good luck!
Kal
