im currently using my vizio 19 inch m190va as a pc monitor hooked into my laptop via vga and ive never seen such great colors on a tv or monitor before should i get a dedicated monitor for my computer anyway though?
My Hitachi TV works great as a monitor.. I use to use a Sanyo.. that TV is happier being just a TV.. I would think vizio would be a great monitor.. I just read recently that Sony sold off vizio division. There are many new monitors out there.. that automatically change resolution.. but they are kind of pricey.
If you are happy with the picture on the TV, than that is all that matters. You can use it. Try to set the computer's display output to the native resolution of the TV (720p, or 1080p).
