New monitor, new fun
(Well, cheap second hand monitor)


This one supports DP 1.4 in it's OSD, but seems to not give any more bandwidth than when ran at DP 1.2
Two cables tested, both claim to be DP 1.4 / 8K capable

GPU-Z shows 5.4Gb/s x4

The monitors values are very different between HDMI and DP, but i'm hitting a wall where it blanks out at even 590Mhz on DP, despite it going higher on HDMI (for a lower refresh rate)

Anyone got suggestions beyond running CVT-RB2 and hoping for the best?

Also If I enable free sync it seems to have more problems - should I be altering the Display properties to match the new overclocked refresh rate (an entire 66MHz, yay) - or leaving it alone?

DisplayPort 1.4 doesn't mean it supports HBR3. If the monitor only needs HBR2, it doesn't need to support HBR3. If it goes blank at 590 MHz pixel clock, then HBR3 wouldn't help because 4-lane HBR2 already supports up to 720 MHz.

You should edit the FreeSync range if you want the refresh rate to use FreeSync. Some monitors behave differently with FreeSync vs. non-FreeSync refresh rates.
