I have a 27es HP monitor. I was not aware that you could overclock the refresh rate of a monitor so please excuse my lack of knowledge on this. My monitor has a VGA port and HDMI port. I have a GTX 1060 6GB. When I go into the NVIDIA control panel and customize the monitor, I am able to go up to 80Hz. However, when I push apply I get this box that says input signal lost and then starts counting down from 30 to put my monitor to sleep. When I looked up what this mean't apparently people said that the bandwidth of the HDMI cable is not strong enough. I was able to gather that DVI cables are pretty good when overclocking and that there are new HDMI cables that are better for overclocking. Problem is, when I look if these HDMI cables are compatible with my monitor it doesn't show up. So basically, I have 3 questions, if I buy a converter cable(HDMI to DVI) will it be more powerful than this HDMI cord that I have which would allow me to overclock? Is this monitor capable of handling the updated versions of HDMI cables so I can overclock? Can this monitor even support overclock because some people said that it is not the cord and that it is the monitor. If anyone can link me a cord that will give me a better bandwidth to overclock then please link me some.
