USB 3.0 to HDMI in 2K (wqhd / 2160p) resolution

post #1 of 5
Thread Starter 
I have been looking for an external graphics card to run a 2K (or WQHD) monitor via an usb 3.0 port. I could find a lot of results but none of the sellers send SHIPMENTS TO BELGIUM. Wenever I do find something, it's extremely overpriced (looking for a price tag around €60). I'd be very happy if someone could help me out.

Any solution is welcome, no matter how many adapters and plugs, as long as it goes from usb 3.0 to hdmi (2.0) with at least a max resolution of 2160p :rolleye:)

External graphics card via USB 3.0? No such thing exists.

it does, but for what I need, they are all way to expensive.

USB 3.0 has nowhere near the required amount of bandwidth to push a 2560x1440 display at gaming speeds. That would need, at the minimum...

2560 x 1440 x 60hz x 24bit color = 5.308 gbit/sec.

This doesn't count extra lines added that are offscreen and necessary (though IMO should be deprecated fully since they were required to make analog displays work [CRT]) to drive the display.

The maximum theoretical bandwidth of USB 3.0 is 5 gbit/sec. Usually all USB connections don't get anywhere near this speed for whatever reasons (latency, signal loss, error correction, etc). It might be possible with USB 3.1 but I wouldn't hold my breath, as such an adapter would cost several hundred dollars.
