Hey, Could you explain how to adjust these values? I'm having issues using 18.6.1 or above because of monitor blanking even at native resolution. I've tried creating a custom resolution and adjusting both H and V porch values -- adjusting one by +1 or -1 but there wasn't any range or numbers that worked for me. So far, 18.6.1 and now 18.7.1 are unusable for me. DDU clean install or "clean install" option in drivers introduce a "bad" output signal. I've tried even a driver update via device manager from 18.3.4 (last known driver for me with working VSR) to 18.7.1, but instantly get monitor display issues when it's done updating.
