Vista wont detect all supported resolutions for Plasma via SVGA cable

Ok so I have a relatively odd but crippling problem. I started using my laptop to watch HD divx videos on my Samsung HP-S4233 plasma TV about a month ago. I would connect my laptop using a an old VGA cable and set the resolution to 1920x720 (to match the video file) and everything worked beautifully. I decided to get a longer cable to make the connection easier and ended up with a 15' SVGA cable. I connected the TV to my laptop as usual but when I went to adjust the resolution, I was shocked to find I could only select 800x600 or 1024x768. So I thought it must be the new cable but no, the same problem occurred with the old cable.
I have tried updating my video card drivers to no avail.

I must thank anyone for their help in advance as this is really an important feature for me.

More about vista wont detect supported resolutions plasma svga cable
  1. To get that resolution you will have to use DVI, HDMI, VGA or Component connection. S-Video can not display at that high of resolution, I think 1024x768 would be the best possible and not sure of anything over 800x600. If I remember correctly S-Video is limited to about 525 lines of horizontal resolution. I have my puter hooked up to my TV and am given the choice of 800x600 or 1024x768 (which is almost unreadable on my 40").
  2. No no, not S-video, SVGA. Its an upgraded vga standard.
