Help me solve this 'not-so-easy' dual screen setup problem.

[Zeze]

I have: PC, laptop, monitor (1080), and HDTV (1080p)

Whenever I wanted to watch stuff on internet, I'd hook up my laptop to the HDTV via HDMI. Zero problems, ran beautifully at TV's 1920x1080.

I got sick of hooking up laptop, so I got a longer HDMI cable so I can dual connect my PC to monitor + HDTV.

Problem 1: For some strange reason, PC connected to HDTV shows the TV screen letterboxed on all 4 sides, despite being set at 1920x1080 and had zero probs from the laptop. This persists on all cases of extending 2 displays, TV only, and duplicating both screens. Wtf?

Problem 2: When the TV was hooked via Laptop, the sound would automatically come out from the TV, not laptop. But with my PC's dual screen setup, sound comes from my PC speakers. Is there a way to tell my PC to use TV speakers at will?

Thanks.

If you're using Windows, you can use the control panel Sound settings to change your default audio device. I use this to switch between computer speakers, the TV's built-in speakers, or the receiver.

Motavian is right on about Problem 2

What video card in the PC? I believe AMD has an option called overscan somewhere in catalyst control center that you adjust to fix Problem 1

HD6870.

Why does this occur only with HD6870, but works well with crappy laptop? I really don't want to use stupidly bloated CCC (currently using latest driver only).

Unless you're running a single core Pentium 4 with 1GB of ram or less, the "bloat" is completely neglagable. Install it, make the adjustment, problem solved.
