Acer T232HLbmidz 58.4 cm (23 inch) monitor (VGA, DVI, HDMI, USB, 5ms response time) black (Personal Computers)
For touch operation from Windows 8 the monitor at your desk is just the right size. Also, I was pleasantly surprised how well the monitor can be tilted. This one has the impression he is part of the desk, and you can very easily use all applications
