Using a Dell E198WFPv flat screen with a replacement Acer X275 PC running Win 7 Pro 32 bit. The thing auto-dims at indiscriminate intervals. We go and set the brightness value to 85% on the OSD. Exit out. It's fine. But then at some point, either a couple of minutes or a couple of hours later, it dims. Go back in to the OSD settings and the brightness is back to 0. Push it back up, exit and again at some point it drops back to 0. This sequence has to be done 10-15 times a day.
I set this back to 85% and Exit. I go right back in immediately just to check and brightness is still at 85%. Exit.
Settings on the Acer. Control Panel > Power Settings > Balanced > Turn monitor off = Never. Programs > Acer > ePower Management = Max perf (no dimming).
Is there a special key press sequence we have to invoke to ensure the OSD settings are imposed AND saved? So that we don't "lose" the settings?
