I have a PC tower but no monitor for it. It turns on, can get power, but I need to see what is on it. I have an idea to connect it to my laptop to play games with. Like install the games to the tower and access them via my laptop. Is this possible?
The VGA/HDMI ports on a laptop are most likely to be Outputs, compared to monitors that have Inputs.
There is no easy way.
One thing you can do, get one USB TV Tuner card, Install it on your laptop, Connect PC tower's output to TV tuner card and and you will be able to see it on your laptop. Now do whatever you want to do on your PC Tower and use Laptop's Display.
I can't recommend because I havn't use any of them. Just see the Spec. Mainly you will be needing VGA to USB Tv Tuner card. Generally USB TV Tuners have AV or cable input. So be careful there.There are a lot of different ones. Which would you recommend is best for an ASUS X53U with Windows 7 Home Premium and an AMD Radeon HD 6290 display driver?
It's far easier to buy a new monitor, you could probably get a cheap 24-inch 1920x1080 PC monitor, rather than messing around with a TV tuner. I'm not a PC gamer, but I would have thought a direct connection to a monitor would have a better response time.
