First time poster so sorry if I am new to all of this. I had an old tower PC that I kept around because I wanted to hook it up to my HDTV. I hooked it up by a DVI to HDMI output to my 46 inch 1080p TV. When I did, the computer ran and windows started up, but it was unbelievably slow and I could hear my computer processing sound nonstop. I would take a whole minute to open firefox and just navigating around my desktop was so slow. Now when I streamed divx movies off the net, the videos themselves ran fine and had no noticeable lag.
At first I thought this was my computer, but when I connected this same computer to a 24 inch monitor by DVI output, it ran totally fine.
Any ideas or solutions? Is the size of my screen the issue here?
It very well could be the size of your screen. I dont know too much about it because i usually only use computer monitors, but if the computer is trying to fill up all of that space with High Res pixels, it could just have it thinking a LOT more.
