hello. I used to have NEC projector and had no problems with great picture. currently I am using g70. I do not see much difference in sharpness compared to pg plus but lc lenses are great. my setup is not perfect yet. my question is how to disable internal patterns and do convergence using outside signal. NEC was easy. thank you. Robert.

Keep hitting the pattern key; it will toggle through to the internal patterns and one will be an internal/source overlay and one just your source.

hello. thank you. I do not understand how could I have missed that. probably I had never hit pattern key enough times. Cool

. it is working fine. thank you again. Robert.

As you work with it, you'll figure out how to get more out of your G70. It should be better than your old projector in every area except convergence. The G70 is especially good for mechanical focus, electronic focus, and white level on an 8" CRT.

hello. picture looks great I have no complains in this department. it needs some minor touch ups at corners especially right upper corner. it may be connected with lens flapping. I have it for two years and it was set up without factory reset. do you think it is worth to zero everything and start anew? it is a lot of work though. the resolution is 1080i from PC dvi and internal Moome card with gamma. thank you. Robert.

It would also be worth it to setup 818x1920p @ 72Hz from your HTPC. This would be a resolution for 24Hz film based content. It will provide the benefit of 72Hz, but take less bandwidth than 1080p 60Hz. You'd use the 1080p 60Hz for 1.78 and the 818p for 2.35 aspect ratio sources.

Hello. I have ati video card so custom resolutions are out of the questions, unless i will install powerstrip. I do not think I want to play with source signal side. I am tempted to try factory reset. Is there any risk of killing the projector? Will I loose all gain and color calibration? I am not worrying about convergence. one cannot go wrong if enough time is spent and proper order of steps is taken. I might try to do it with a little encouragement. Thank you. Robert

Well do yourself a favour Robbo and piss that ATi off, throw in a superior nVIDIA, and dont look back.

Also i think you should try 1920x1080i at 96Hz, and 1920x1080p at 48Hz. Both are likely to look nicer than standard timings 1080p 60Hz.

At first, put full white on and focus the lenses until you see the grain of the phosphor, then you can move on.

Hello. I am trying to set up my second g70. It works well but ... The red tube was replaced by owner and I have problems with centering all three tubes. It seems like red one is too low. I had to Max green and blue and min red to converge them. I have tried first with magnets but there is only a minor difference, unlike nec PG. What is the cause of this. Was a red tube installed incorrectly? Robert.

Rob, use the 'zone' adjustment. Take the R and B shift controls back to 128, and use the middle zone adjustment. that's the coarse raster shift, and it's normal for any or all of the V settings to be way off the default 128 midposition.

Thank you for help. I just did as you said and all is good. I am used to NEC projectors which have more "manual" controls. This one being much younger are all electronics. I have it on 70 inch screen and picture is excellent. Watching Laurence of Arabia now. Robert.
