hi

i know its not cool, but i just dont have any meter or money to buy one now,/
sooo, please, just try to tell me about bad alternatives to do at least some kind of reasonable colour and greyscale calibrations on my nec 6pg plus with tube wear... i would love to have test pictures posted with some kind of text like" looking at picture 1, now turn the xxxx until.." or something like, if you got


PLEASE

thanks and lg christoph

You can get reasonably correct color using HD Essentials test patterns and the filter that comes with the disc but make sure you only tweak the user accessible controls - don't use any internal adjustments such as R,G or B video gain otherwise you will get into serious trouble. If you have good vision and PERFECT color vision you can get an approximate greyscale by carefully tweaking the grid voltage on each tube but again, you could get into trouble if you don't have a sound technical understanding of what you are altering. You could damage a tube by doing this.

Bottom line is - you really should get a meter or get a professional to calibrate your projector. There are some reasonably priced meters around that maybe aren't perfect but will still give you an acceptable picture.

You could build a DIY optical comparator with a high-CRI (Color Rendering Index) D65 flourescent tube. The big problem is dimming them, so some neutral-density filter material would likely be needed as well.

The previous poster is absolutely correct. Do not adjust any chassis pots without a scope. Everything you need is in the setup menu, unless the CRTs are too far gone to be balanced.

thats a good one! and they realy go away for less than 50 bucks.. hmm )

@fastscot, sounds good, but i would need to buy the HD essential dvd AND some mentioned Filter though.. is there no way to do anything reasonable without any additional stuff than a good test pattern?

@fifawei WTF?)

You can get an iPhone app... It works well enough for this purpose compared to the eye...

No idea, i also have an S4, but the iPhone 5 blows it away, so i dont bother with it unless im at work.
