Administrators Hervé Posted November 10 Administrators Share Posted November 10 Sorry but I don't understand what you're saying about HDMI. IOReg shows that you most certainly did remove all the unnecessary stuff from your config but no external screen attached to con1 or con2. Were you trying to say that your laptop froze or crashed when you plugged in an HDMI cable/screen? If so, try and patch con1's pipe as follows: framebuffer-con1-pipe 12000000 DATA Re: camera not working, you probably need to remap your USB ports after changing SMBIOS.

Administrators Hervé Posted November 11 Administrators Share Posted November 11 You inject property: disable-external-gpu Does your Thinkpad have a dGPU? If so, HDMI may be wired to it. Link to comment Share on other sites More sharing options...

pawan2joy Posted Tuesday at 06:17 AM Author Share Posted Tuesday at 06:17 AM i read online that someone faked the 620 to 630 mobile graphics and HDMI worked.. I tried but didn't work.. Can you help as what all need to be changed to fake graphics.. Display The model of Integrated Graphics is Intel UHD Graphics 620, faked to Intel UHD Graphics 630 (Mobile) . The HDMI is attached with Intel UHD Graphics 630 and is functioning normally. 2K@60Hz & 4K@30Hz are supported. Link to comment Share on other sites More sharing options...
