I have been trying to find a cheap display that I can take with me as needed for my Playstation 3, and whatever else. Well today I found a very cheap solution. If you have a newer lcd monitor with DVI connectors that isn’t being used then just get yourself dvi to hdmi cables. You may not get the highest resolution, but it will serve the purpose.
If you have any other money saving solutions please feel free to let me know, or comment here.
