About the Windows own display menu (Control Panel \ Appearance and Personalization \ Display \ Screen Resolution) can be set easily by drag and drop the monitor arrangement. In my case, for example, the laptop is not about the middle and the two external monitors on the left and right of it, but a monitor is directly on the laptop, the second is right next to offset. The menu can be the real arrangement of the Windows user interface transmitted, so that the transition of the cursor from one monitor to another actually so runs as the monitors are arranged (I hope you understand what I mean), which, for good intuitive user makes.
The adapter is compatible with Windows 8 or 8.1 (64-bit), although this is not explicitly mentioned in the article description in the manual.
Loss of quality I can not determine. I test and reference images in the before / after comparison (ie once directly via HDMI on a laptop and even with intermediate adapter) tested and noticed no difference. Although I must say that I use the monitor only for simple text, Office and Internet applications as home users, and can therefore make no statement as to whether the device would suffice even the most demanding video and graphics editing. I for one can not notice any differences.
In addition, the adapter is extremely performance friendly. "Feels like" I have already found no difference in task manager but you could see that the monitor operating on the adapter takes about 100 MB RAM. In my 4GB of memory that were 1-2 percentage points more of occupied memory, so not worth mentioning.
The adapter is in use a little warm, otherwise the part is completely unassuming, noiseless and also processed well.
In short, I can recommend this product without restrictions. The installation by Plug and Play was easy, the image quality is - as far as I can believe my eyes;) - does not affect the current operation is absolutely stable and liquid. In addition, the device is future-proof thanks to HDMI and USB 3.0. A good investment.
