LENOVO BRIGHTNESS CONTROL MOVIE
Movie to GIF Converter is a powerful tool to convert video file to animated GIF file and enables you to add over 50 effects (Add Text, Add Image, Adjust Brightness, Adjust RGB, Adjust Contrast, etc. I followed the solution in this thread but it did not work for me. Adjust Video Brightness And Contrast - Brightness - Brightness Controller - Superior Brightness - Dim Brightness. Brightness control keys respond and I can see the brightness bar goes up or down, but this has no effect. the regular buttons (F11 and F12) do not work and even if I go to control panel and change the brightness, there is nothing happens.

Brightness is always at maximum in my laptop and I can’t change it. Everything works perfectly so far, except a small issue with the brightness controls.
