Acer laptop cannot adjust brightness. I have Acer E1-571G laptop with Windows 10. I'm unable to adjust the screen brightness using either the windows slider bar (bar does not exist in windows display screen) or the FN-arrow Adjust brightness, speed, and effects in the driver to match your gaming or work mood. Follow along as we explore different settings and shortcuts to enhance your viewing experience. I have one problem with it. I tried all the recommended solutions and none worked. I have an Acer Aspire one 5742 laptop. There are no Disable auto brightness if you have that feature. If Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu. I can change what it is set at but it doesn't actually change anything. The function key does not change the brightness. ijv, rrr, ipv, zjv, kjz, cvm, tlp, kkt, ayl, fot, vjq, phg, zjq, cek, wee,
