Super good value, too slow when connected 64GB instead of 32GB HDD, very poor screen via HDMI

The main details of this device have already been mentioned several times:
Long battery life, very compact and above all very very inexpensive (a complete PC, including Windows and Office for under 200, -. Euro, which is really great)
BUT
The screen is really bad. At 30cm viewing distance, the colors in the landscape mode invert already when the head. 10cm moving sideways. He is really grainy (although the resolution would be high enough)
One could get the idea to connect the device via HDMI to a monitor. But then the weak processor / GPU is overstrained. HD content on YouTube or Amazon Prime / Instant bucking strong, everything is going very tough.

With the monitor I could resign myself, the lack of performance over HDMI is for me but a reason for return (mind you: I'm used to much faster systems who previously had an old Windows XP notebook, the feeling quickly than adequate.!)

TIPS:
1. "mobile.HD Media Player" from the Windows Store (2.99 €) can play almost all video formats in the new touch design. Thus even Full HD movies via HDMI are possible.
2. Be sure to update to Windows 8.1. This brings several GB more memory and a real performance gain. On the Acer website to find a driver package which you can still play after the installation.
3. The current batch delivered via Amazon has a 64GB HDD, instead of the displayed 32GB, Super!
