Title: Megatouch Calibration
Post by: jaeger on January 08, 2013, 03:10:42 pm
Just upgraded  my megatouch aurora. In calibrating the screen, when the first screen comes up at 600 resolution I can calibrate it with no problem the the second screen comes up 800 resolution and the screen is too large for the monitor and can't be calibrated. If I press a game that need the higher resolution  the screen goes blank. All other games play fine but I can't calibrate the higher resolution and i can't figure out how to make it smaller to do so.
Thank,
Jaeger

long time since i worked on megatouch but i do remember having to press auto on the lcd control pcb for each resolution before calibrating each res

ive seen this and had to call support.

it's a bad ram stick.

pop in a new one. (pull out the old one and throw it away. don't try and hotdog it and add another stick to it, it'll start crashing on you)

512mb is minimum for 2012+ software now anyways

Thats odd, never seen that before. Not doubting you though. Ive seen this when the display controller was going bad. Like bad cap or graphic chip overheating. Weird one was a horizontal white line across the screen. Thought it was the lcd, but just needed to add a low profile heatsink with some artic silver adhesive epoxy. worked like a charm ever since.

the video is on-board, thus, it shares a portion of the system memory for use with video. the sticks they used are about as cheap as they get. (likely Chinese rejects being resold)  the system normally runs 640x480. it doesn't use much of the RAM.

when you change resolutions, 800x600 and up, you use more RAM and it gets into the sketchy area. sometimes you can get it to work, other times it does the off the screen thing.

Like i said, that is very strange and isolated. You would think bad ram would cause problems long before even getting to the calibration screen. I cant even Imagine with all the problem there systems had over the years, the fustration that company put operators through, especially after the warrantys ran out.

the flavor of Linux operating system they use is a very unusual system. you can have issues with RAM and hard drive but never know it until you change the software or update it.

the system always runs in the same memory space. The drive images have the data in the same places. hell, the data isn't even verified while it's written. if you have a bad sector on your drive (that the disk SMART hasn't sorted out), the system install will run right over it without verifying the data. The data remains corrupted.

same with RAM. It always runs in the same space...you load up a game that runs in 800x600 and boof! screen is all messed up cause now it's using an are of RAM it doesn't normally use.

the whole thing is a real kick in the nuts.

i'm kinda scared for their new LIVE system... that's windows.

well....if one where to keep the files on their own server...

...and one where to use some kind of protocol re-direction to their server...

...then the megatouch would think it was connected to the server.


or not  :dunno whatever.

The question is....Are all the needed files on the local machine, or are only the basic files like the os on it. I havent even seen one of these systems yet. All the places around me have aurora's or RX's still.

hello,
I have the exact same issue with my aurora, hi res games were going off screen, same with calibration screen, changed ps and now you can play all games and calibrate fine, but currently trying to upgrade to 2012 software and the accept license box/button is off screen just like prior attempts before ps swap. just read this blog and swapped ram with 512mb out of a used pc and still cant upgrade. any suggestions would be greatly appreciated (:
