I have been using this TV in my living room as an HTPC monitor for some time now and I am very happy with the results. I have a 4 year old Dell with a Core 2 Duo processor and 4 gigs of RAM. I added a NVIDIA GeForce GT430 video card with HDMI out to the Pioneer AV receiver with HDMI in/out to the Samsung TV. Since I am using the TV with an HTPC, you will have to re-set the display to "Medium - 125%" for the "10 foot user interface" look on Windows. This will make your desktop icons easier to see and not look so grainy, plus you can surf the net from your couch without straining your eyes. For viewing all of my local movies, photos and music I use XBMC which is the best HTPC software available for viewing all of your content. I store all my content on a NAS connected to my wired network. And, I have a Logitech camera mounted on the top of the TV for Skype. Since this TV is not Full HD, sitting 10 feet across from the screen with the above configuration will give you the best results. However, if you sit right in front of the screen and use it as a computer monitor, the icons will look grainy.
