Graphics card Questions

What's the best way to setup my graphics card to use multi monitors?
I'm using Win 10 Pro with a new GEFORCE® GTX 1660 Ti

My card has this connection capability:

• 3 x DisplayPort 1.4
• 1 x HDMI 2.0b
• Quad simultaneous display capable

My Touchscreen can be connected through USB port or through Video card.
------------
What I would like to do is connect a touchscreen monitor
that will be 'independent' of my main monitor.
e.g. a different program on each screen (completely idependent)

For example I want the 'touch' actions to operate on the 'touch' monitor
NOT the Main monitor.

At the moment... when I press the Touchscreen I can see the 'impression'
on my main monitor, but no work is done on the 'touch' monitor (a bit difficult to explain)

In fact, it causes actions to occur on my Main monitor... not the Touch monitor!

Any thoughts? :?

Your screen configurations are incomplete - the 'touch' region isn't overlapping the 'screen' region on the touchscreen.

Run this and follow the instructions - should sort it, make sure you've got your desktop layout arranged the way you want it first.

Code: Select all

multidigimon -touch

Thanks for the info spikey.

Looks like I'll have to do some reading.

It's best to have matching monitors when using multiples. You night get it to work with different models, but if they match, you only have one active monitor driver at a time.

Windows touchscreen support is still somewhat unpredictable. In some cases it only works well with the primary screen. I have no idea if that's because of different resolutions, driver issues, or Windows itself. It's the same thing with external tablets, Windows sometimes does weird and funny things when the aspect ratio of the tablet is different from the screen ratio.

But... if you're lucky it works 8)

I'm still having a problem. :|

I'm trying to hook up a main monitor with 2 Touchscreen monitors.
(the touchscreens can be connected through USB or directly)

I had connected them with USB and am not having much luck.

I even bought a 'DisplayLink' docking port.

Now, I'm waiting for some Directport cables for the Touchscreens so I can connect them directly to the graphics card.

The type of connection monitor - graphics card should not matter.

In Windows a touch screen is an 'input device', there can be multiple input devices, each with a seperate set of coordinates, and multiple output devices (read: screens), each at their own coordinates.

Each touchscreen needs to be connected to the PC via it's own USB.

So...

USB1 -- Touchscreen 1
Video1 -- Touchscreen 1

USB2 -- Touchscreen 2
Video2 -- Touchscreen 2

Sometimes an external screen can be connected over USB (typically a secondary screen). These are relative slow, so it's better to do it with seperate cables, and use 'real' video drivers instead of some USB solution.

Make sure you install the proper drivers. After that, assuming you run Windows 10: https://support.ctouch.eu/hc/en-us/arti ... indows-10-

A word of warning though... some (older) drivers do not play nice with multiple touchscreens, or combos of touchscreen and tablet. (Admittedly, I tried some older stuff. Perhaps newer stuff is better.)
