Evergreen offers a small 2 ports HDMI hub (1080p). A nice product, not for its design, but for the infrared remote controller, so you can hide the hub way back behind the TV and only leave the small IR receiver visible (1.4m). The hub works with or without an AC adapter and measures 80x55x17mm.

If the 2 ports model doesn’t suit you, Evergreen also offers a larger 3 ports version. But who would want an HDMI hub at 671,505.00 euros?? (they won’t sell many of those if they put the wrong price on their e-commerce website..!)
