Using a TV in Cabinet-Needs Assistance setting up

[GGKoul]

I have a GeForce2 MX 400 with SVideo on my computer and I'm connecting to my TV via the SVideo  port.  

Having just tested the system, my desktop icons & icons are blurry.  But I can run a high res screen saver and it looks perfect... So what gives??

As I would like to know who people who have TV's in you cabinet... How you are running your system?  As well, I'm running Windows MAME, and I'm just wondering what setting within MAME should I have checked in order to best view the games.

Also, are you able too start you PC and have the PC use the TV as the monitor?  As a picture doesn't appear on the TV until it logs into Windows.   And even then, it loads on my PC monitor before the TV.  

So I'm undering how to I set the TV as my default moniter.  

As well, Is there any place where I can find out how "best" too setup the my MAME system?  As I'm not too sure what the different windows options do.

Thanks!

trouble with geforces and TV out is that you don't know what you have.  Since there are a bunch of companies making geforces, they all use different brand/quality tv-out chips.

As far as I know, ATI is the only tv-out available in Dos, so you will have to get into windows anyway.

As for the blurry, I think that most will do this if you try to run the desktop at higher resolution that the TV can physically handle.  Many cards act like you can get up to 800x600+... but high definition TV's can only handle 512x512 or something (something less then 640x480).  Anyway, then it needs to combine pixels.
