Thanks for the help with the overscan issue, I feel embarrassed I hadn’t noticed that option on my TV before. (I had to set my Samsung LN26C350D1D to “16:9”.
Regarding keyboards, I’ve tried two:
- Apple model # A1243
- Microsoft Natural Ergonomic Keyboard 4000 v1.0
No keystrokes on either keyboard are recognized. Neither keyboard’s caps lock, etc. LEDs will light up, but the “Fn” LED on the Microsoft keyboard does light up. So it appears the keyboards are receiving power, but that seems to be all I can verify.
Other USB devices, specifically a wired mouse and USB stick, work perfectly.
Any advice?
