[Bug 1661987] Re: Wrong colours on some monitors via USB-C to HDMI
I have the same problem on Hirsute Hippo. I am on a Lenovo Yoga 730, connecting to a Coms projector from usb-c through a lenovo usb-c to hdmi adapter that was included with the laptop. I have had no trouble before connecting from the same laptop through the included usb-c to VGA adapter. I cannot get the colours right even by having the projector connected on boot. This laptop also has intel graphics. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661987 Title: Wrong colours on some monitors via USB-C to HDMI To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1661987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I did a new test with another laptop with Intel graphics and Ubuntu 16.04, but which has an HDMI port, connected to one of the three Samsung TVs, and the colors look fine. Also, for what it's worth, I compared the EDID information (obtained with "get-edid | parse-edid") from this laptop with the one from the T420, and it's identical. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661987 Title: Wrong colours on some monitors via USB-C to HDMI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-edge/+bug/1661987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1661987] Re: Wrong colours on some monitors via USB-C to HDMI
I think I have the same issue: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1586787 The colors on the TV look weird the same way that your colors look. I tried your workaround (restart the TV), and it fixed the colors for me as well. (Thanks!) Details on my case: - It happens with two laptops and three Samsung TVs. - The laptops are a Lenovo ThinkPad T420, and a Fujitsu (I don't have this one near me right now, to give the exact model). - The Samsung TVs are of different sizes, from different generations (about 4 years apart), one is "smart" (Samsung UE40J5200AW) and the other two are not (I can provide exact models if needed). - I'm using a DisplayPort to HDMI adapter to connect to the TVs. Actually I've tried multiple models of DP to HDMI adapters and various HDMI cables. - On both laptops, the issue does not exist when booting from a Linux Mint 17.3 Cinnamon. But it does happen for: Linux Mint 18.1, Ubuntu 14.04 (on which Linux Mint 17.3 is based), Ubuntu 16.04, Ubuntu 16.10, Ubuntu 17.04 (the latest build as of today). It looks to me that the commonalities for these issues are two: Samsung TVs and recent Linux distros. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661987 Title: Wrong colours on some monitors via USB-C to HDMI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-edge/+bug/1661987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
