Hello, I am new here, and I have seen some very good posts around. This seems like a really nice forum. Anyway, I am wondering how to use my TV as a monitor. I have read around about it, and it seems pretty cool. There may already be a topic that explains all of this, if so, please show me where. I know the PC I am currently using most likely does not support it, but I am hoping to build a PC soon, or I could upgrade this one to support. This PC is a off the shelf Dell, and I also have a pretty old Gateway. Please let me know everything on how to set it up, as well as if I should just wait until I build a new PC to have it(also, please let me know what other parts are recommended to help support the display). Thank you
