Satisfactory but resolution change

I bought this switch in order to connect my Wii (with VGA cable) and my PC to my monitor. The case is a bit tricky at the VGA and avoid pressing too hard. It is very simple: there are only the bare necessities and the name of the brand. I was expecting a relatively large product but it is not: it holds easily into the palm of the hand and is very light! The buttons are plastic which gives a look a little gadget but they are effective and that's all that their request.
The only real negative I have noted is that through this switch, my PC (both Windows 7 on Ubuntu) does not recognize my monitor as a 1080p Full HD, but a lower resolution. On the Windows desktop that can not be seen, only when I run the games in full screen, which therefore can not be displayed in 1920 * 1080. But Ubuntu on the desktop resolution is very low and can not be changed for a better qualitée by plugging the monitor directly to the PC.

So I took it for 4 VGA Switch because it was costing less than 2 or 3. It is very convenient and saves me plugging / unplugging the cables behind the central unit (which in the long run, can damage them) as I do not want to play or go to Ubuntu (though it must be manually fixed). Finally, it is small and light which allow the same to stick under a desk.
