If you've recently bought a high refresh rate monitor, you've possibly found that by default, Windows sets it to 60 Hz and leaves it there. There's a good reason for this, but there is also no reminder telling you to raise it to 144 Hz, 160 Hz, 240 Hz, or whatever your display's intended refresh rate is, making it very easy to overlook -- especially considering the setting to raise it is hidden deep in the old-style Windows settings .
Now, in the new Insider Build 20236, available today to users in the dev channel, Windows is adding a refresh rate selector to the new Windows 10 Display Settings menu, making it much easier not to forget about it.
Why Default to 60 Hz on All Monitors?
The reason why Windows will default a new monitor to 60 Hz is simple: compatibility. In practice, it would hardly ever go wrong, but imagine that Windows 'thinks' a monitor is capable of 144 Hz, when really it's limited to 60 Hz. If Windows were to accidentally set the refresh rate above the monitor's capabilities, you would simply get a black screen and be unable to set the signal to a setting that makes your PC usable again -- not without grabbing a different monitor.
With a manual selector, you get that 15-second dialogue that switches back to the old setting unless you click yes in time, so it's clear why we need a refresh rate selector and why Windows defaults to 60 Hz.
Will The Complaints of Choppy 144 Hz Screens Finally End?
The new slider will be placed in the "Advanced Display Settings" menu, which still requires an extra click from the main Display Settings screen. We would prefer to see it right underneath the first resolution selector, but alas, we still have to dig one level deeper.
Still, that's three clicks less than how it works today, where after reaching "Advanced Display Settings", you still have to go to "Display Adapter Properties for Display X'"in the classic-style Windows menus, then to tab "Monitor", and then select the correct refresh rate.
Don't Forget Color Settings for 10-Bit Displays
Once you've set your new monitor's resolution and refresh rate, don't forget to double check the color settings too. For now, these are found in your GPU vendor's drivers. In Nvidia's case, you have to go to Nvidia Control Panel, where in the 'change resolution' sub-menu, you can change the color settings from 'use default color settings' to 'Use NVIDIA color settings'. If you have a monitor that is capable of interpreting a 10-bit signal, you'll want to select that option, along with RGB color output format and the full dynamic range.
In most cases, the default color settings will be fine, but with some very high refresh rate monitors that don't support DSC (display stream compression), to free up bandwidth for more frames, Windows might default to the YCbCr422 color format, which causes visible artifacts around text due to chroma subsampling. In this case, you can lower either the refresh rate or output color depth to regain the full RGB color format, depending on which sacrifice you prefer to make.
