Refresh Rate Tested: 100 Hz

Excellent low input lag when the PG348Q is overclocked to 100 Hz. Normally we test monitors at the native refresh rate, but in this case, there is a significant benefit to run the monitor at 100 Hz and no significant downsides. Note that 100 Hz is only possible over DisplayPort; HDMI is limited to 50 Hz and there will be more input lag.

Over DisplayPort the only possible resolutions are (3440x1440, 1024x768, 800x600, 640x480), and only 3440x1440 is capable of 100 Hz. This isn't usually a problem though because most graphics cards will upscale lower resolutions to 3440x1440 without you even knowing.
