Title: Video keeps shifting off center Post by: hotrod777 on June 13, 2013, 07:23:33 PM Ok, the GK that I was shopping myself a few days ago has a skeleton in the closet.
Quick details again: GK 4.0 on a 39 board, no Medialite board 17" LCD of undetermined brand (I haven't looked yet) The 17" is attached to the old CRT pull-out chassis, not attached to the door. On the top edge of the screen is a micro-button board with a green LED. At various time the video will shift 1/3 of the way right off the screen. The touch screen remains oriented correct as to where the buttons "should" be, its just the video itself that's moved. If you hit the "auto correct" button on the board mentioned above it will pull the video back in to the correct place. But then it occurs again a random times, sometimes at start up, sometimes during play. Any ideas??? I will try later tonight the quick fix that i found by searching... not sure if it will apply. The other thread with video problems said to open door and key twice to he touch calibration menu... he said that took the "noise" out of the video Title: Re: Video keeps shifting off center Post by: hotrod777 on June 14, 2013, 12:45:47 PM In case this might help someone else:
I think I corrected it. In the menu of the monitor it was set to IGT AVP. I set it to IGT 39, hit the auto scale button, and it re-scaled to exactly the right screen size (prior it kept a 3/4" boarder around). I guess it might have been fighting a resolution thing, or a ratio thing. Anyway, I hope it holds. Also, going into the touch calibration menu took the vertical line noise out of the screen :244- Title: Re: Video keeps shifting off center Post by: Yoeddy1 on June 14, 2013, 09:32:14 PM Which monitor do you have?

It must have been fighting a resolution mis-match Title: Re: Video keeps shifting off center Post by: Yoeddy1 on June 17, 2013, 10:22:02 PM I was just curious where you saw this IGT39 setting. I have a Wells Gardner monitor, and can't find any such setting.

On this monitor it had: IGT AVP IGT 44 IGT 39 Bally PC Composite and maybe a few others... After setting to IGT39 and hitting the "auto adjust" button, it squared up and looked twice as good as it did. It still had some vertical line "noise" on the video, and based on another thread I seen here, I toggled into the calibration screen, then back out. That made the blue background crystal clear/clean. |
