decent machine with small pitfalls at different terminals

I had not so much of my purchase.
I wanted to connect my computer to the projector at the same time and the monitor without having to use the analog signal. the catch is that the monitor and the projector have different resolutions: 1920x1200 and 1920x1080 (1080p). Contrary to the current product description makes my Splitter (bought in Januer 2011) By the way, uncomplaining 1920x1200.
The problem lies in identifying which (in this case the PC) reports back to the splitter to the source: This is namely a mixture of the two connected devices, and the highest possible resolution that is reported the lowest common denominator, in this case, is therefore 1080p. This is in many instances, well-sense was in my case, but exactly the opposite of what I wanted, because I wanted to continue to operate the monitor with the highest resolution and only switch on projector using 1080p.
Should pay attention to who buys the device so that all modes that you want to use, are also supported by two terminals. This could be a problem even in less exotic situations, such as when two devices is only a 3D-capable.
Apart from a solid piece of equipment, unkaputtbares METAL, and is doing what it should.
