Displayport to HDMI not working - testing of components already performed.

post #1 of 3
Thread Starter 
So my friend has an EVGA GTX 1070 FTW (3DP, 1HDMI, 1DVI), and ACER brand R240HY monitors (HDMI, VGA, DVI). He also has displayport to HDMI cables, but they don't work between the two (the monitor does not have DP in so this isn't an option).

We have tried the following.

Laptop Displayport out into the monitor HDMI - SUCCESS. (shows cable does work and monitor HDMI input works)

Displayport out of the GTX1070 with a displayport to DVI converter then DVI cable into the monitor - SUCCESS. (shows signal does go out the displayport port on the GTX1070)

Now that we know all 3 parts of the loop works, so why do I get these results?

Displayport out to HDMI for monitor - FAIL

Displayport out to HDMI into a nearby TV - FAIL


And yes we've tried a number of them weird workaround settings that people have had success with such as maximum power saver settings and the like.

Drivers for GTX 1070, 372.90. PC was built on Monday, so all other drivers are up to date as of that day. BIOS to my knowledge have not been tinkered with.

Thank you in advance!

why can't you just use the HDMI port on the 1070.

Did you try rebooting the system with the new monitor config?

Rebooting had been performed roughly 5 times during the process, including with the initial setup of both displays being hooked up via the displayport out.

The reason he cannot simply use the HDMI to HDMI as there is only one, and he has two displays that he wishes to use with this setup. And the reason he cannot use the DVI+HDMI config is because the color recreation is off when using these two display types. The preferable solution, which he has invested his money into already, would be to use the Displayports on the card and as we have proved, do function, but we cannot figure out why his computer cannot push a signal with DP to his monitors.
