Hi, I have two monitors with the current following configuration: Screen 0: minimum 320 x 200, current 5120 x 1440, maximum 16384 x 16384 DisplayPort-0 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 164.83 + 59.95 + 120.05* 96.01 72.01 60.01 143.97 120.00 74.97 [snip] DisplayPort-1 connected 2560x1440+2560+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 165.00 + 59.95 + 120.06* 96.04 72.01 60.01 50.01 48.01 144.00 119.99 99.99 [snip] HDMI-A-0 disconnected (normal left inverted right x axis y axis) HDMI-A-1 disconnected (normal left inverted right x axis y axis) DVI-D-0 disconnected (normal left inverted right x axis y axis) The pp_profile_mode: NUM MODE_NAME SCLK_UP_HYST SCLK_DOWN_HYST SCLK_ACTIVE_LEVEL MCLK_UP_HYST MCLK_DOWN_HYST MCLK_ACTIVE_LEVEL 0 BOOTUP_DEFAULT: - - - - - - 1 3D_FULL_SCREEN *: 0 100 30 10 60 25 2 POWER_SAVING: 10 0 30 - - - 3 VIDEO: - - - 10 16 31 4 VR: 0 11 50 0 100 10 5 COMPUTE: 0 5 30 - - - 6 CUSTOM: - - - - - - I have set their refresh rate to 72.01 which is a mode equal for both, and the MCLK wasn't downclocked either. They are branded HP and Scepter. Using a vtty doesn't help either. Is having the exact same monitor really required? If not, how can I check what is causing the memory clock to be pegged that high? I'm using 6.0.0-6-amd64 from Debian testing. -- Braiam
