matuskela Posted November 18, 2014 Author Share Posted November 18, 2014 hello should boot -f to rebuild caches and the platform is 0x01660004 maybe the kext is loaded is the one in caches.. good hack  Many thanks Artur-pt! Follow their guidelines, as I am using chameleon, needed just reinstall the patched kext (preferably with kext utility or similar) and use the following flags: GraphicsEnabler = Yes = No IGPEnabler IGPlatformID = 01660004 I'm posting a kext corrected again (correct me if I can not do this) to anyone who has problems with artifacts on the screen in Lenovo G400s. Just missing test the HDMI output, I'll do that when I get home and post the results. Thank you dear Artur-pt!

matuskela Posted August 8, 2015 Author Share Posted August 8, 2015 Hi Mendietinha! I'm using the flag IGPlatformID = 01660003 would it? 1080p HDMI port works but the notebook screen is with artifacts , if I change from 1080p to 720p both work without the artifacts but at 720p , but for this to work I have to go there in the display settings , putting 1080p and return 720p as soon linking it comes with independent video configuration artifacts. Remembering that I am using the original kext AppleIntelFramebufferCapri unedited in Yousemite . Quote Link to comment Share on other sites More sharing options...

Â When you say "FB = 3" means a specific flag ? Do these artifacts may damage the video or the board over time ? Quote Link to comment Share on other sites More sharing options...

matuskela Posted August 14, 2015 Author Share Posted August 14, 2015 There is a problem of damaging the graphics card in notebook using with the artifacts ? For the hdmi port will not be with the artifacts and the notebook screen I'll close and work with only the TV to HDMI . It can damage something the being with artifacts on display closed ?
