    HDMI-to-analog: can I control overscan/underscan?

    Hey all,

    I recently got an HDMI cable and HDMI-to-analog converter box (the converter box was well priced at ~$40 and can be found here: Amazon.com: HDMI to Composite /S-Video Converter 3RCA CRT TV CVBS: Electronics).

    It all works quite well, and the picture is surprisingly sharp on our older Sony flat-ish (still analog) TV. Picture even looks decent without using the S-Video cable, and now that TV can serve up anything the A100 can deliver (I use BubblePNP to stream from a DLNA-enabled NAS as well as using a media server from my iMac). Things are fine, except the picture sent to the TV is too large for it -- can't recall whether that is "underscan" or "overscan" -- but I am missing out on a wee bit of videos/movies all the way around.

    Bottom line is, how can I control screen proportions in the HDMI output: horizontal size, vertical size, stretch, etc.? The converter box only has input and output and switches for NTSC/PAL and SVID/RCA video -- no additional controls or on-screen capabilities. I remember having a VGA-to-TV converter back in the day that would allow some control over screen geometry, but was hoping there might be an app I can run on the tablet for that? Some sort of HDMI output controller app? There is not much in the way of controlling HDMI output in the system settings (that I could find), so I am hoping there is something I can do via software...

    Any ideas on what to do (or a better place to look) would be mucho appreciated. The picture is OK already, not to mention the ability to stream music and pictures, I would just like to tweak it to perfection, if possible.

    Thanks in advance!
