Windows 10: DVI-D-dual-link issues

Hi,​

Is it possible that the DVI-D-dual link which worked perfectly on Windows 7, does not work as dual-link on Windows 10, and instead functions as single link, thereby not allowing the 60Hz refresh rate and possibly also leads to dithering/FRC/PWM etc? ​

I think I have a problem with the DVI-d-dual-link that is somehow related to the fact that I changed from Windows 7 to Windows 10. The problem is that the display works, I can see everything, but something is wrong.​

I have some visual sensitivity issues, and I need the display to be free of dithering, flickering, PWM, FRC etc. The hardware I have, worked perfectly for me, as long as used Windows 7 (64-bit), 16-bit-color mode. However, since I installed Windows 10 (64-bit) 32-bit color mode, I have these visual sensitivity issues. I am using exactly the same hardware I had before (I only added an SSD hard drive on which the OS is installed).​

When I go to the advanced display settings>display adapter properties>adapter> list all modes: I can choose 1920x1200, 32-bit, 59Hz or 1920x1200, 32-bit, 60Hz.​

However, although I choose 60Hz, it does not change it. It remains 59Hz.​

The display menu indicates it is on 1920x1200 60Hz.​

In contrast, the GPU says it is on 59Hz refresh rate.​

Is it possible that the DVI-D-dual link which worked perfectly on Windows 7, does not work as dual-link on Windows 10, and instead functions as single link, thereby not allowing the 60Hz refresh rate and possibly also causing dithering/FRC/PWM etc? ​

120hz Monitor, HDMI or DVI-D cable?


If you believe a (usually) reliable source, you'd have to use the DVI-D input to run 120 Hz.

Overview and Specifications - ASUS VG236H 23-inch 3D Display Review: 120Hz is the Future

I'm not sure about HDMI standards. HDMI 2.0 can do UHD (3960 X 2160) at 60Hz. HDMI 1.4 can do UHD at 30Hz. The latter would barely permit 1920 X 1080 at 120 Hz, if the limit was the pixel rate. Both standards may be newer than the monitor that you list.

As regards multiple monitors, the 970 may have a lot of digital connectors. A Gigabyte example (GV-N970G1 GAMING-4GD) has one DVI-D and one DVI-I; both are dual link. It has 3 DP outputs. There are DP to DVI dual link adapters available, but they're active and start at around $30 in the USA. Single link are much cheaper (but can't provide high bandwidth).

I have no idea what maximum number of monitors can be connected to a 970.

 

120hz Monitor, HDMI or DVI-D cable?

I just wanna play games 1920x1080 at 120hz, anyting above doesnt matter to me at the moment. So by saying "both standards may be newer than the monitor that you list", you are basically saying that i should use dvi-d because the monitor ain't able to handle 1920x1080 at120hz using hdmi?

The maximum number of monitors wich can be connected to the 970 gtx is 4 if i recall right.

(playing games like various mmo's, overwatch, titles like mass effect and so on)

 

Need help finding good DVI-D Dual-Link cable

Cards usually don't ship with cables; monitors do. They usually ship with a DVI-D dual link if they have a DVI cable. A lot of monitors I've seen that come with VGA and DVI only included a VGA cable.
