Whistle from fit-VGA
Posted: Sun Feb 27, 2011 4:04 am
Hi,
I'm using fit-VGA with Beagleboard-xM (linux kernel 2.6.32) and it works great with resolution 800x600@60 but at higher resolutions I have an issue. At 1024x768@60 I can see the clear picture for about a minute and then I hear light whistle from the fit-VGA and my monitor goes in power saving mode (it looks like there is no signal at the output of the converter). This weird whistle can be fixed only after powering of/on the board.
Could you please tell me if it's an issue with fit-VGA or I have to use some specific settings for resolutions higher than 800x600? Thanks.
Cheers,
Max.
