That's quite a distance. You'll need some expensive cable to get that distance without suffering quality. As well, your wireless keyboard and mouse may not work at all depending on what sort of physical obstructions are in the signal path. You didn't say whether the keyboard and mouse you have now are PS2 of USB. Since you'd be running 50 feet of video cable, you might as well go that route if you have PS2. It's going to be awkward and cheap video cables will give you fuzzy images and poor color. You'll need one that's well shielded and high quality.
I would like to be able to keep the PC in my bedroom, but be able to use it in my living room by using another monitor and wireless keyboard/mouse. So I was looking for a longer monitor cable, about 50ft.
Right now I have it connected with the monitor cable that came with a Dell monitor. I guess your standard monitor cable.
So I just want to buy a longer version of that..Will any 50ft VGA cable do?
It's just a regular Dell Monitor. And my computer info is below,just in case you need it.
