Title:
Wrong colors on external TV
Status in xorg package in Ubuntu:
Expired
Bug description:
Hi,
On a Lenovo Thinkpad T420, with an Intel Core i5-2520M CPU and
integrated graphics, when using a Samsung UE40J5200AW 40in TV with a
DisplayPort to HDMI adapter and an HDMI cable, the colors are very
wrong on the TV.
This happens on a brand new Ubuntu 16.04 installation made from
scratch, and it does not happen when I boot from a Linux Mint 17.3
"Rosa" Cinnamon 64-bit live DVD. So same laptop, same adapter, same
cable, same TV, and the colors are fine on the TV in this case (Mint
live DVD). Also, when switching the laptop with a Dell running Windows
8.1 (so the same adapter, cable, and TV are used), the colors are
again fine.
I have attached a picture that shows the laptop screen in front of the
TV screen with the display mirrored. So both screens should look the
same in the picture. But it looks like only the white color is the
same, while the rest of the colors are very different.
Thanks for your help,
Alin.
