Note that, IIRC, the EDID shows 12bpp support, and the TV does in fact support 12bpp. However, my Rotel RSX-1058 receiver only supports HDMI 1.1, thus preventing 12bpp support. I've worked around this issue by editing the EDID to disable 12bpp support. This is done by the drm_kms_helper.edid_firmware kernel flag.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
