Custom Resolution Utility (CRU)

[BLUuuE]

Hey ToastyX,
it seems that AMD has removed the 56 blanking limit and I can run a blanking lower than that. I was messing about with the timings, trying to decrease them as much as I could and testing it on a 70Hz refresh rate rather than my 72Hz. This is the lowest I could go without my monitor going a bit fuzzy. https://puu.sh/xwN1K/7751135576.png

However, when I tried these timings on 72Hz, my monitor became fuzzy, which means that to achieve higher refresh rate you need looser timings (similar to RAM)? But looser timings means higher pixel clocks which is usually the limiting factor when overclocking monitors.

Also, what do the range limits do?
