Raspbian Jessie saved my defected Raspberry Pi 2

As I mentioned long time ago, My Raspberry Pi 2 cannot detect monitor resolution!!! It always set default resolution of 640x480. (It should be the first batch of RS version) That's why I have to bought second raspberry Pi 2.

Today I test new Raspbian Jessie on the defected Raspberry Pi 2, unexpectedly it can recognize the correct resolution.

Here is the same Raspberry Pi 2 running Raspbian Jessie (32G Ultra Class-10 micro-SD) vs Raspbian Wheezy (16G Class-4 micro-SD).

1440x900 detected in Raspbian Jessie

640x480 detected in Raspbian Wheezy
