That's too bad. And I'm assuming there's nothing I can do to reduce blanking even further to get the clock rate down to what's supported? According to the cvt tool, this is the mode for reduced blanking at 3840x2160@60, but there's a relatively new mode for reduced blanking v2 that's supposed to reduce it further still. I don't have access to the relevant standards, however, and can't run the spreadsheet which is public without Excel. I don't know if it's possible that the monitor would support a mode it doesn't advertise, but I figure it's worth a shot. Any idea what the proper modeline for reduced blanking v2 would be, and if it's under 450 MHz?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
