Custom Resolution Utility (CRU)

RE: Custom Resolution Utility (CRU)
Hello,

I just tried to do some OC on my U28D590D monitor, and have some questions :

By using DP port of a 290X tri-crossfire configuration, "Pixel Clock Patcher" shouldn't be needed right ?


Started testing with 1080p resolution, and maximum refresh rate attainable without failure is 86Hz, moving up to 1440p and 1800p it is reduced to 85Hz.
So I thought 85-86Hz is the limitation of LCD panel itself and it didn't change across resolutions, but moving towards 2160p (native resolution of monitor), things got interesting:

In CRU, maximum refresh rate that can be chosen in LCD Standard mode is 73Hz, in LCD Reduced mode it is 77Hz. Any value above is forbidden with refresh rate marked in red and all other fields not filled.
But in Windows refresh rate scroll down list, only 67Hz or below in LCD standard mode and 69Hz or below in LCD reduced mode can be displayed and chosen.

Similar thing occurs to 3520*1980 resolution, in LCD standard mode, CRU let me set as high as 86Hz, but only 79Hz and below can be displayed in Windows refresh rate scroll down list and chosen.

So questions :
What is the reason of CRU's limitation upon refresh rate ?
(4K in LCD standard mode gives a 73Hz maxi refresh rate, anything above is forbidden in red color)

Why refresh rate that can be chosen in Windows is lower than in CRU ?
(4K in LCD standard mode gives a 67Hz maxi refresh rate, anything above can't be displayed in scroll down list)

Thanks in advance !



BTW, how does OCing of monitor impact its lifespan ? I'd like to hear from a forum dedicated to that.
