1120 Posted March 14, 2011 Share Posted March 14, 2011 At the begining I tried this and this.... no result... backlight is off. But when I read and tried this.... it worked only on external VGA (D-Sub). But now my backlight is on. Also I read about DSDT and DualLink patch, but I can't compile my DSDT.dsl file (attached below) and add DualLink patch. Is any DSDT guru can help me with my problem, and generally, am I on right way?

1120 Posted March 14, 2011 Author Share Posted March 14, 2011 I tried EDID it didn't help me. My external D-SUB LG L1718S working in 1280x1024x32@75Hz mode with QE/CI. But I don't have image on my internal, only backlight.

PWX Posted May 14, 2011 Share Posted May 14, 2011 Have the same problem on my Aspire 7741g. Allways blacklight on internal display. VGA output works only(can't test HDMI now, maybe it works) Quote Link to comment https://www.insanelymac.com/forum/topic/251954-acer-7741g-hd5650-internal-display-sl-1066/#findComment-1683387 Share on other sites More sharing options...
