This is my initial review of the HT23 monitor having just bought it and set it up. I went for this monitor to use on a Windows 7 two monitor set up that was using 2 Dell 20" monitors. On receipt I was surprised how thin the box was, when the monitor was removed from the packaging it was actually pleasingly slim, fairly weighty and looked like a quality product.
I have used my LED TVs to display HDMI resolution 1080 PC pictures before and have never been satisfied with the results, particularly text was very poor. I was therefore fairly convinced that this monitor would give similar results and would be on its way back to Amazon.
I simply unplugged the a Dell DVI connection, plugged it into the HT23, connected the monitor power supply, and booted the PC. Windows booted, I changed the settings to make the HT23 the primary monitor. The picture was vibrant and crisp, slightly too bright but really excellent. Sitting next to the other Dell monitor the HT23 was clearly a far better picture. Text was really sharp and surprising for me considering my previous experience of 1080 big screens. Brightness was easy to reduce to around 80% from 100%, other adjustments are made from an onscreen menu system that is operated from switches on the back of the monitor.
I then connected the USB cable, Windows loaded some bits and pieces automatically and I rebooted the PC, the touch function then worked a treat. Very easy to use and sensitive to the touch, a very good touch experience indeed. I set windows to work with single tap and it is now just like using a really large tablet.

TL;DR - This is a somewhat flawed product. There appears to be an issue with the power supply and I also recommend that you read the 1 and 2 star reviews before considering it.

I am in two minds as to whether to keep this monitor which clearly has a fundamental design fault. It looks beautiful, the display is crisp and neutral - all in all it is a very nice monitor, if monitor is all you want.

The touch interface is where things get troublesome. The monitor worked once when first switched on with DVI-D video connection, USB (for the touch HID feature) direct to a motherboard USB port on my HP Pro 3500 micro tower PC and power. Power is an external switching power supply directly attached to a moulded 3 pin plug; the output voltage is 12V via a fairly standard coaxial power connector similar to the type used for many laptops - polarity is positive on the inner connector, negative on the outer. The power supply has only a plastic pin where the earth pin would be as is common with this type of supply – no earth necessary.

At the second and every subsequent boot, the monitor simply did not come on. I have another monitor connected to the analogue (VGA) output on the computer so could see that it was booting, although it was complaining that no keyboard was connected. The keyboard was in fact connected to the motherboard USB port directly adjacent to the one I had used for the touch screen connection. By moving the keyboard to a different USB port on the front of the computer, I was able to regain control of the computer but there was still no display on the HannsG monitor.

As the USB connection seemed to be indicated as a likely problem, I disconnected the touch screen USB interface by pulling the USB plug at the monitor end. Two things happened immediately.

I am extremely happy with the performance of this monitor, which I bought at the same time as a new Windows 8.1 desktop computer in order to benefit from a touch-screen. It works very well and the resolution is first class. The speakers are no more than adequate but then I do not use the desktop for listening to music.
The handbook, however, is disappointing, appearing to be poorly translated and confusingly expressed. It took me 24 hours to get any sound out of the speakers because the handbook fails to make clear that, if the monitor is connected to the computer's graphics card with an HDMI cable, you must NOT use the audio lead supplied. In fact, the handbook instructs you to connect both the HDMi and the audio lead. It was only when, by a frustrating process of elimination, I disconnected the audio lead at both ends, that the monitor's speakers suddenly sprang into life. It is a shame that the manufacturers skimped on the handbook when they have produced a very fine monitor at a competitive price.

We had one of these and when connected to a nearly new laptop, the laptop died. We thought it was a fault of the laptop, and sent that away for repair (new motherboard). On the next outing of the monitor (we use the monitor occasionally, for exhibitions), all the USB ports of another laptop we connected to it failed. Only at this point did we suspect the monitor (still less than a month old). We tested the power supply and found it had over 80 volts of a.c. breakthrough on it (at low current). We took the monitor back to the retailer and said 'if you do test that, be careful', to which they replied, 'yeah we know, we've had another of these break one of our computers already' and refunded us. We thought Hanns-G ought to know, and they were very communicative, but ultimately said that the 80v a.c. on what should have been a 12v d.c. power supply leading to a 5v USB connection was normal, and denied liability for the equipment failures we experienced. Note also the 1-star review by David Morgans who similarly suffered equipment damage, and the 3 star review by Bruce Miller who says "Rather alarmingly when I tried reconnecting the usb plug bright sparks arced between the PC and plug."
