Please help me understand what I can realistically expect from a 1680 x 1050 native resolution on a 16:10 screen. Please talk about scaling, overscan, quality degradation, etc...from PC games, HD/BD DVD, DTV and HDTV.
I'll tell you what my dell 2001?fpw does:
PC Games: run em at 1680x1050, which if they know about widescreen, looks fine. Otherwise i use ~1280x1024, which gets pillarboxed on the sides.
HDTV via the pc: MCE - small black bars top/bottom on 16:9 content, to preserve the aspect ratio. MCE has some zoom controls you can use to make it use the full vertical space at the expense of chopping the sides.
PS2 on svideo: the monitor has controls to make it full screen, or 4:3. If the game knows about widescreen, i do fullscreen, so the AR is slightly off 16:10 instead of 16:9.
I dont have component in, so i dont know what it does with a 720p/1080i input.
