> after many conversations, i have understood that i must connect USB cable together with VGA /HDMI/DisplayPort ...
YES!
To activate the two "downstream" USB ports on your monitor, and to activate your touchscreen, you need to connect that USB cable -- that is why the cable was supplied with the monitor.
P.S. Try connecting the DisplayPort-to-DisplayPort cable to your monitor and your computer, and using the 'OSD' on your monitor to select input from the DisplayPort cable. This might provide a clearer display than when going through your VGA-to-DisplayPort adapter.

According to: http://www8.hp.com/h20195/v2/GetPDF.aspx/c05238082.pdf
you need to connect a USB cable from your computer to the "upstream" USB 3.0 port on the monitor, to use the USB ports on the back of the monitor, and, I am guessing, to treat the touch-screen as a HID ("Human Input Device"), i.e., like a mouse.
Have you connected such a cable?

> I did it ...but still not works
Was there a "Getting Started" document that was shipped with the monitor?
If not, see: http://h20565.www2.hp.com/hpsc/doc/public/display?sp4ts.oid=11176889&docLocale=en_US&docId=emr_na-c0...
> should I need to change those cables connecting from computer to monitor ?
> I have 3 kinds of cables: Display-Port cable, VGA cable, and HDMI cables.
Each of those cables will support "video" output from the computer to the display.
I doubt that _ANY_ of them will send the touch-screen gestures from the display to your computer.
> Right now I am using display cable .which is SUB 3.0
I doubt that this cable is a USB 3.0 cable.
I'm sure that you need to use a USB 3.0 cable from your computer to the "upstream" USB port on your monitor.
Experiment: put a USB memory-stick into one of the two "downstream" USB ports on your monitor.
Does your computer detect the presence of the memory-stick?
If not, then your computer will not detect the presence of the touch-screen,
until you connect a USB cable from the monitor to a USB port on your computer.
Again, look at: http://h20565.www2.hp.com/hpsc/doc/public/display?sp4ts.oid=11176889&docLocale=en_US&docId=emr_na-c0...
Look at picture #4, in that document, which show the necessary connection of a USB cable.

Not all the pictures on that web-page are numbered!
Look at the picture between #4 and #5, with the text 'USB' above the picture.
Experiment: put a USB memory-stick into one of the two "downstream" USB ports on your monitor.
Does your computer detect the presence of the memory-stick?
If you change the #4 cable, does it make a difference?

> Actually ,,, I can use by regular mouse ......but can't use by touching ...
Correct. Is the "tail" of the mouse connected to a USB port on your computer?
Are there other "empty" USB ports nearby to where the mouse connects?
> Actually ... I have 3 cables .
> 1 VGA ....
> 2 Display port .....
Neither of these two cables will activate your touch-screen.
> 3 USB
I presume that your USB cable looks like this one:
The "white-rectangle" end must connect into your monitor.
The "flat" end must connect to a USB port on your computer.
I presume that your computer has at least one available USB port ???
> none of them are not able to connect computer directly ......
Really? None are not? Does that mean that all of them ARE working?
Look at this picture:
The above picture shows 4 different connectors.
Which of the sockets that accept these connectors are present on your computer?
> so I bought adapter to connect with VGA and ...another one for ...display port ......
> and VGA and DisplayPort are working with adapter
I think that you are "trying too hard". Use either a VGA-to-VGA cable, or a DVI-to-DVI cable, to connect from your computer to your monitor. But, if you are successfully getting an image on your monitor, don't remove any cable.
> for USB I don't have adapter .... ...BUT touch screen is not work .... that's my issue ...
To repeat, you need to connect a USB cable, as stated above, to get the USB ports on the monitor to work, and to activate the touchscreen.
