Acer XR342CK: adjusting freesync range over HDMI

[rv8000]

Long story short, I've been having loss of display issues over DP upon boot using a certified DP cable (I've checked two other DP cables including accel and amphenol), and have since switched to the hdmi 2.0 input on my xr342ck which for one reason or another completely remedies the issue.

When testing using the DP cable I was able to adjust my freesync minimum down to 42hz from the stock 48hz, for an overall range of 42-75hz without any black screening during loads below, above, and inside the fps threshold. Since switching to HDMI I have be able to set the minimum refresh rate as low as 40hz without any loss of signal using CRU to edit; CRU 1.3, edit the extension block for the monitor, then edit the data block for freesync range.

I checked a few games and all seemed to be working properly from 40-75 hz. Shut my pc off for the night and when I went to start my pc up, it would boot but there was no signal to the monitor. With the pc still on I unplugged and plugged the hdmi cable back in and the monitor displays a signal with no further issues. I then tried to adjust the minimum up in 1hz steps until I arrived back at the standard 48hz minimum, yet the monitor would not display a signal upon boot (reinserting the hdmi still cable still worked). It was not until I completely reinstalled Adrenalin that my monitor would behave normally.

Is there something im missing in terms of creating resolutions or adjusting another setting to avoid this weird boot issue while using HDMI? The only problem seems to be the no signal upon boot.
