A Digital Foundry report points to lower quality video playback since upgrading to the Xbox 360′s new dashboard.
According to Digital Foundry’s investigation, users of the new dashboard have complained that it “forces video content to run at limited range RGB levels, the net result being that colours are washed out, with blacks becoming grey”.
DF ran some comparisons and concluded that it’s “clear that the 360′s new dash is not functioning properly”. In addition to wash-out colours, DF found that “video compression artifacts are considerably more noticeable” and that “macroblocking that would be otherwise be less apparent within darker colours is now more readily visible”.
The site could find no solution to the problem in the console’s settings menus. Microsoft has made no comment on the matter.
Beta testers claim to have reported the issue to Microsoft prior to the dashboard update’s roll out, only to be thanked politely but advised that the feedback would not be incporporated in the final release.
