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. 1. the HannsG monitor came on and 2. the keyboard was again recognised on the original motherboard USB port – the one adjacent to the one recently disconnected from the HannsG touch interface.
So far we have a working (and still very beautiful) touch screen monitor, with touch functionality disabled. I want touch to work though, so now what?
I tried reconnecting the USB cable but as soon as the external metal part of the plug (a standard B type USB plug) touched the exposed metal part of the USB socket on the monitor – i.e. before it was fully engaged – the monitor went off. The power light on the monitor also went off. Simply moving the USB plug so that it was no longer in contact with any part of the monitor restored power. It appeared that the monitor power supply was being pulled down by some form of power leakage to the USB interface.
As I have an external, powered USB hub also connected to the same PC, I decided to try the monitor USB connection via that hub, rather than directly. This worked immediately and has continued to work without any issues, so I have a functional display with a working touch interface and I do really like it – I just find the fact of this USB power leakage more than a little troubling.
PS Others have complained about sound. I have not tried it. Inbuilt monitor speakers are never any good and I would not single out the issue of poor sound as a reason to discount this product. I have an external 5.1 sound system connected which works well.
PPS Amazon please fix the description of this product. You say that it includes a DVI-D cable. It does not. Supplied cables are power (shudder), analogue video (VGA), analogue audio (3.5mm type) and USB (type A to type B). That is all.
Bought it as a present for my husband who's very delighted to have it. It is huge and for the price, I couldn't even ask for more. Being a touch screen monitor is also an addition to its features, which we really love. Definitely giving it a five star
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.
I can use touchscreen/mouse/keyboard/virtual keyboard/touch pad in any combination on the new screen, even my wife who only uses a tablet, was up and running a few seconds and loved the size of the desktop and browser window, commenting how good for online shopping it would be!!
So my initial opinion is great picture - graphics and text, great flexibility using various inputs as required. Very pleased with this product and almost surprised how really good this monitor is. When you couple this with the price, it is a winner.
I'll update this review if there is any change.
Update (after several days)
The sound quality from the internal speakers is not up to much, they do not compare to the Dell sound bar quality. Apart from that this is proving to be great monitor.
