In Win10 1607 games doesn't see 60.00hz, only 59.94hz. BenQ EW277HDR
Hello, guys. I'm looking for a help with a strange problem with detecting the refresh rate of my monitor by games. First of all, I have three different installed builds of Windows 10: 1607, 1709 and 1803. And problem presents ONLY in 1607 (aka AnniversaryUpdate of Win10).
So here it is. Native refresh rate of my Benq EW277HDR is 60.00Hz. At least I believe that its native. Ofc, I checked actual numbers of the refreshrate at vsynctester.com and testufo.com. It is aprox 60.00077Hz. This is what Windows10 call 60hz for me in the refresh rate list options (nvidia options as well). There is another mode in that list called 59Hz, that actually equals 59.94Hz (proved by tests as well). All of those three builds of Windows 10 have these two modes. CRU shows identical parameters as well, in which I have only ONE 'Detailed resolution' with 1920x1080@60.000Hz.
In 1709 & 1803 of Win10, I have a choice between 59.94 and 60.00 Hz in the game options. But in 1607 Win10, once I launch a game, only 59.94 is available. I tried to change nvidia drivers - no luck. Found advice to delete TV resolutions from CRU > Extension blocks - no result, 59.94 is still in place in games, while Win10 1607 itself works at 60.00Hz.
Any thoughts how do possibly fix it, please?!

Seems like I've almost solved the issue by deleting "CEA-861 Detailed resolutions" along with corresponding resolutions from "TV Resolutions" data block. Everything looks fine now, except missing 59.94hz option at all.
