rebop Posted April 13 Report Share Posted April 13 Hi folks, I have a Lenovo P51S system working as expected until recently. There have been two changes i have made. First, the issue prompting this is in the DEVELOP module of Adobe Lightroom VER 6 (last perpetual license I have been using for 10-12 years?) The screen will go black om the external monitor and it displays a signal cannot be found. It might come back, or I might have to turn the monitor off and on to get a screen back. This is a Lenovo P51S with Optimus M520. It may not be working as Optimus properly right now, either. Along the way several months ago there was an update from Lenovo for the Intel Video driver. This caused DWM in windows to go out of control eating RAM. A known issue. SO I updated the Intel driver manually. It went to colored hash on the screen until reboot and then seemed to work fine and the DWM issue corrected. But I did do this manually. Problem? Then, I bought a new camera and image sizes went for 18-20MB to 60-80MB per image. Perhaps that is stressing the video? At any rate, Lenovo drivers are old. I would like to feel I ma properly installed and unsure if a manual update of NVIDIA to 528.89 With fix all Optimus, Intel and Nvidia or if I need to uninstall anything, install Intel and Nvidia separately, be sure Optimus is working. ANY help sincerely appreciated. Thanks. ~Bob Quote Link to comment Share on other sites More sharing options...
