End Game: My laptop connected by hdmi to a LKV312PRO (hdmi splitter) thne two monitors connected by direct hdmi cable.

Display required: Not using laptop screen display. 1st monitor is primary Image stretched over 2nd monitor.

I have had a good fiddle around but I cant seem to figure out how to do this. I have the image on the laptop duplicated over all three screens at present

know of a good video that shows one how to do it?

AFAIK I don't think an adapter like that will support extended desktops (I presume this is what you mean by 'stretched over') across the two displays, as all it does is duplicate the HDMI signal.

You need a display port MST hub to do it, and support from the graphics chipset.

HDMI splitters will just split the one picture to both screens.

My work set up is a thunderbolt 3 docking station with dual HDMI outs plus I added one of these adaptors to achieve 3 independent screens, ymmv but above works for me

When I tried a similar single port USB 3 to HDMI adapter it was pretty bad. Basic applications worked ok, but it was quite laggy. Even moving the mouse on it felt like one of those fake mice pointers that games use where there is a bit of lag, and you could often see things redrawing and compression artifacts on edges that were moving etc. Many games wouldnt open with the drivers for it even installed, even if I unplugged it, and thruput on USB took a huge hit when it was in use.

Would not recommend.

will have to give it all some more thought spending $40 on a spliter was ok but once you go near or over a hundred you have to give it some thought

That's interesting, I haven't had any lag issues other than when running 4 screens (laptop +3 externals)
