Running a Geforce GTX 770, i5 4670, ASUS Z87-A into two Acer H6 Series 23" IPS LED HD Monitor through HDMI to DVI-D cables. I have had the first monitor for about a month with no issues at all and I just picked up the second monitor. Currently the top port is working fine on both monitors but regardless of what monitor/cable combination I plug into the second port it is not reading at all. Also if I turn on the computer with a monitor plugged into only the second port it will show the computer booting and once windows loads it turns black. Any help would be appreciated.

Did you set it up to extend the display to the second monitor?

No option for that on the drop down menu. Like I said, windows won't detect the 2nd monitor at all.

Have you tried the clean install option of the NVIDIA drivers? There's an express & custom option, the latter where the clean install is located. This purges the old drivers (& settings) & installs the new. 

 

The latest NVIDIA drivers are here. It may be best to disconnect all monitors except the main & start over. Oh & make sure that any dual graphics options, such as the built in Intel ones, are disabled in the BIOS. Otherwise, you may have issues. The Intel i5 4670 has inbuilt graphics (Intel HD Graphics 4600). On my system, I have this disabled for the higher WEI score alone.

Hope this is of some help.  :thumbup2:

Performing full disc images weekly and keeping important data off of the 'C' drive as generated can be the best defence against Malware/Ransomware attacks, as well as a wide range of other issues.

Did a clean install with no luck. Pretty sure I disabled the inbuilt graphics in the BIOS as well with no luck. Windows still does not detect the 2nd monitor.

Can you give us the exact model and specs of your graphics card?

badr0b0t's suggestion above may help a lot. The GeForce GTX-770 is supposed to have support for up to 4 monitors. The exact model would tell us a lot, as various OEM's configures the cards differently.

If this is your card, there's an issue somewhere. Should run two monitors with ease, some OEM's modifies the settings. There's the remote possibility of the PSU being not enough also, but that's too early to know at the moment.

is that monitor one of those that has the analog d-sub vga and dvi-d connectors? most do.

 

i am looking it up now...looks like it has the d-sub, dvi-d and hdmi inputs

 

there is the possibility that the internal monitor menu has to be toggled from analog to digital. if not that, there may be other menu options that the internal monitor menu has.

Nvidia has it's own Control Panel. Look under the display section >  multiple monitors.

So I got both monitors running by using the hdmi ports in the card but now my cursor keeps flashing the hourglass beside it a fairly high rate.
