...especially for CRTs.How much the calibration costs depends on what the tech does. You might ask the calibrator what the $125 includes. Most RPs I know started at about $200.
I haven't seen a CRT RP that didn't improve after an ISF calibration. If your set was one of the very rare ones that wann't delivered in "torch mode" - the contrast, sharpness and brightness cranked up - you are are amazingly lucky.
Even my 34" CRT improved after calibration.
Follow Ups:
I recently purchased a Mitsubishi HC900 DLP projector. I have been reading on this forum about the improvement calibration make. Is calibration recommended or even an option for this projector? I purchased a service plan with the projector, so cost doesnt really matter; the service plan will cover the calibration if I can have it done.
Is there any particular way of finding/choosing someone to calibrate it? About how long should i expect it to take?
Thanks for the help.cheese
always helpful.Some have suggested that I have at least 100 hours of usage before having it calibrated. Agree?
Also, if you dont mind answering, Im having an HD cable box installed sometime next week. Should I have the box installed via the DVI/HMDI input(only one on my set) or the component video?
What about DVD player connection. Should I keep the DVI/HMDI input available for that?Thanks again,
Emil
...it takes about 100 hours for a display to settle. Most calibrators won't work on a set with fewer hours. If you're a tweaker, you could always play with AVIA or Video Essentials discs and postpone a pro calibration. (But I truly think an ISF calibration is a good investment.)If you have a DVD player with DVI output, I'd connect it via your set's DVI/HMDI. I think that would yield the most benefit.
But you might ping Joe Murphy for a second opinion.
Enjoy the new display - you will love it.
Emil, I'm going through exactly the same thing as you. I'm one step behind you however. I'm having my Samsung DLP 46 installed (hopefully) next week. Intech Audio, who is installing this baby, prefers to use component cables from the HD box, rather than DVI. They get better results. Maybe with my particular set. HDMI is definately the way to go from DVD to TV. As to calibration? Been doing loads of research. Bottom line? Calabration after the 100 hours of burn in seems is the way to go. Without a doubt. Even if it's only (at the worst) 10 % better, isn't that worth it? 10% of a million bucks is still a respectable amount. Yes? I'll post, post calibration. peace, warren
I have taken the ISF calibration class and currently working toward the certification. Usually for $125 you'll get only one input calibrated. From the class and what I've read in the class text, convergence should be included in the initial calibration. Make sure the set is on for at least 30 minutes before the calibration. There are different methods of calibration, but in general the calibrator should first check focus and convergence. Then center up the user controls and adjust the basic 5 (brightness, contrast, color, hue, and sharpness) using either the service menu or internal (circuit board) controls to calibrate the set so the calibrated settings are also the default settings. This way you have a one-button default. He should also check the white balance with a calibrated sensor and adjust the service menu drive and cutoff controls at two different IRE levels (usually 80IRE and 20IRE) so the white balance is the same at different brightness levels. If the appropriate settings are available, he will also setup the display for day and night viewing. He can also give advice on the correct viewing distance for screen size and the type and amount of bias lighting.The Video Essentials/Avia DVDs are good tools to use for calibrating the DVD input since it takes into account the player and cabling, but not really as accurate for setting up SAT, OTA, or CABLE inputs since it assumes the DVD player output is at reference. An ISF certified technician will have a signal generator he can use to calibrate the other inputs, either with or without your cables.
Some ISF certified technicians can also perform Home Theater sound calibrations, such as correct levels, crossover, proper subwoofer placement, room corrections.
