Hi Robert
Thanks for the reply.
No, I don't have access to a secondary display to test win32_153322.exe (version: 15.33.22.3621).
But I did download the 64-bit version of GFX_Win7_8_8.1_64_10.18.10.3910.zip, extracted the contents and run Setup.exe. There were no problems/issues with the installation of the graphics driver. Everything went smoothly and there wasn't the BSOD (Black Screen of Death). My Dell monitor didn't display the message "Entering Power Save mode" either.
I'm typing this message using the display driver whose download link you specified in your reply.
However based on past experience with installing Intel HD 4600 graphics drivers, I'm not overly optimistic. I remember that the installation of win32_153322.exe (version: 15.33.22.3621) after it was officially released appeared to fix my monitor/display's "Entering Power Save mode" issue. The 15.33.22.3621 driver worked for a month or so and then one day, when my computer was booting into Microsoft Windows OS, my monitor refused to display anything. I had to manually uninstall the 15.33.22.3621 driver after booting Microsoft Windows OS into safe mode.
Summary: the 64-bit version of GFX_Win7_8_8.1_64_10.18.10.3910.zip seems to work fine with my display right now. I shall feedback any problems to you here. It may be days, weeks or a month or two. Hence I'd appreciate it if you don't close this thread yet.
Regards.
Laurie
