Managing EDID on 1070?

[greedy123]

I'm running a duel monitor setup on my 1070, primary through DP and secondary through DVI. The issue it when I turn the monitors off (I often leave the PC on while it's processing renders etc.), the primary monitor (DP) become 'undetected' and everything moves to the secondary monitor.

Trying to research the issue I found this post which is pretty much the same problem. One of the replies looked promising - managing the EDID files for the monitor:

Another solution for NVIDIA cards is detailed in DisplayPort Blanking / Screen Autodetect Problems by setting the monitor to use EDID information from a file instead of from the monitor, so auto-detect is not required.

This is done in NVIDIA Control Panel -> Workstation -> View system topology -> EDID source (for the monitor) -> Monitor... -> Export EDID.

I went to the NVIDIA control panel but the 'workstation' section is missing:

Any ideas how I can do this on my 1070?

bump?

if anyone know an alternative to stop the DP PNP issue please speak up

Going to re-bump this as I'm investigating this too.

Edit: Seems this option is only available on ****** Quadros :/

Edit #2: Got a potential solution under test. Will take a few mins to test as want the monitors to power down naturally to keep it a real world test.

Edit #3: Potential solution I was testing (registry hacks, setting more sensible positions and resolutions for the simulated devices in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration) didn't work, nor did a few little crappy Windows programs I tried, buuuuuuuut disabling "DisplayPort Deep Sleep" on my primary Asus PG279Q, and disabling "DDC/CI" on my secondary Benq XL2411T, and keeping the Windows Power Options set to turn off the displays after X minutes, *may* have done the trick. So check your monitors for similar stuffs perhaps?

If you want to set up custom resolutions then you should be taking a look at CRU (Custom Resolution Utility) by ToastyX which allows you create/manipulate EDID overrides. Saves all that messing about editing registry settings. Saved my bacon on more than one occasion.

I ended up using CRU to sort a similar problem - I also recommend rebooting fully after using it rather than just using the GPU driver restart in CRU as it seems to cause font rendering issues in Windows aero/10 otherwise.
