Screensharing presupposes another Mac is available.
Or you can use for example VNC Viewer from Real VNC on an iPhone/iPad.

I buy a 1060 3gb gigabyte and mymmac don't startson DVI connection.
What pc card can I bay with no flashing that works for 100$ to 300$ max?
Thanks
5770 is an ATI card and should not be affected by the Nvidia web drivers.
The 1060 is a Pascal-based card and these don't work (yet) in a Mac (as pointed in the original post in this thread).
What PC card to buy depends on your needs and what's available to you, but do a search on the forums before you buy. Most Nvidia 5xx to 9xx cards work out of the box, but newer cards require the web drivers. You will not get a working boot screen with an unflashed card. Check also the brand and exact model you buy besides the chipset! For example my Asus 750 Ti needed to be flashed with another PC VBIOS for any digital output to work.
