[Bug 437173] Re: [GM45] Bad resulution choice for mirror mode with two 16:10 displays

 

Yes, the bug is still in natty.   Dell E6500 1400x900 and Dell U2410 1920x1200 both have aspect 16/10.
Still, first common resolution algorithm is used, despite the fact that  in this case a 4/3 one is the first
math and both displays are therefore either scaled/black-bordered. ==> Visually ugly result :(

There a little change as now the first common resolution is now 1152x864 (also 4/3) instead of 1024x768.
Maybe because I've used now a new Dell Monitor Model with DP.
