Title: Screen Noise
Post by: trichmon on May 08, 2005, 02:49:55 pm: When ever i run an app in magnified mode (like opie programs) i get a high pitched buzz. Everything wokrs, and it has done it from day one. I tried reflashing, thinking that it might help but it did not. I am using the stock sharp rom, but i have tried the gpe rom and it had no trouble but I didnt see a way to change an apps resolution in it.

Any ideas?

Thanks
Todd

Post by: offroadgeek on June 04, 2005, 11:47:23 am: Mine too... only when running apps in magnified mode (which I've only done to test this). Though I can only hear the noise when I have the Z screen close to my ear, which I don't often do

Now if someone could make a Z screen sound like a sea shell, that'd be cool
