USB 3.0 monitor good for gaming?

Hello! I was planning to get a AOC e1759Fwu monitor for portable gaming with a GTX 750TI. I was wondering (this monitor is used over USB 3.0) if that would be a problem? Like USB 3.0 being a bottleneck to response time or FPS and I also wanted to make sure that the games that would run on it WOULD USE the GTX 750TI. Thanks!

It depends on their drivers, but as far as I know, all of the USB display adapters use the CPU for rendering. They really aren't suitable for gaming. They work well for mostly static images. The more complex the scene and the more it changes, the more load it will place on the CPU.

The driver basically takes every frame that needs to be displayed and encodes it into some sort of H.264 stream. If you have a CPU or GPU that supports hardware encoding (Intel QuickSync and the like) the driver should be able to take advantage of that. It then sends the compressed display stream over USB where the adapter decodes and displays the stream. The USB3 adapters are much better than the USB2 ones because they don't have to compress the image nearly as much, but it's still doing way more work than a native display. The more motion/change in the display stream, the worse the performance will be.

Thanks! What is a good portable monitor that isn't usb for $50-$140 that you know of? Thanks!
