Why can't I run 75hz on monitor unless lower than native resolution?

[couchpotato]

So I just picked up a new monitor that runs 60-75hz. It has 2 hdmi and 1 vga port. I'm running a gtx 1060 that has 3 display port 1 hdmi and 1 vga. I'm connecting them both using hdmi and It doesn't seem to let me go more than 60hz on native resolution. But if I choose to go to a lower resolution it gives me options on a few to go over 60 to 70,72, and 75 hz. The problem with choosing any of those resolutions is that the whole display becomes distorted and off. Does anyone know why I can't go 75hz on native? Thanks in advance.

What is the model of the monitor?

Does it have free sync? You may only be able to run 75hz if using free sync.

It's an Asus VP278H-P

Does windows see the monitor as the correct model or as Generic?

 

[couchpotato]

Yeah Windows says Generic PnP but NVIDIA Control Panel sees it as Ancor Communications which after a quick search seems to be right for my model.

Install the correct monitor drivers and you should be able to choose 75 Hz. You might be able to select 75 Hz in NVIDIA control panel.

This is what I'm seeing right now on Nvidia Control Panel. 1st one is the native resolution, 2nd is a random resolution I chose that has the option of 75hz. I think I've found the driver on Asus webpage but not sure how to update it. Windows keeps saying it's up to date. Any idea?

when you go into display properties and choose the resolution go to advanced settings -> Monitor -> you can untick the box that says "Hide modes that this monitor cannot display" and that should give you more options. Be sure the mode you pick is supported though as there is a chance of damaging the monitor if you set it too high.

If the refresh rate drop down still doesn't have 75 hz, go to the Adapter tab and click "list all modes" and see if it's in that list. If none of that works you might need a driver for the monitor so the graphics card can detect it properly.

I see, I must've missed that, I figured if it says It'll work at 75hz It wouldn't be at a much lower resolution. Must be a marketing thing, I don't see how I can run at that resolution without distorting the whole display. Thanks rgd1101!

It's worth pointing out that you might be able to run your screen at a higher refresh rate than is officially supported at its native resolution by using a utility to add custom modes. You can find various articles about "overclocking" monitors, such as these, for example...

https://www.gamersnexus.net/guides/1674-overclock-monitor-higher-refresh-rate

Just keep in mind that running a monitor outside its official specifications might not work, or could potentially damage it.

Also, it's worth noting that for viewing videos at 30 or 60 fps, as it common on sites like Youtube, the video will appear smoother with your screen at 60 Hz, since the frames will divide evenly into that. At 75 Hz, some frames will remain on-screen longer than others, which will result in microstuttering, so for desktop use outside of games, keeping your monitor at 60Hz might be better.
