Monitor shows 14ms on pcpartpicker but 5ms on vendor site

[vinnayak]

Hi! Im looking at this monitor: https://ca.pcpartpicker.com/product/Gmkj4D/viewsonic-va2719-2k-smhd-270-2560x1440-60hz-monitor-va2719-2k-smhd

On pcpartpicker its showing up as 14ms, but on the viewsonic site its listed as 5ms: https://www.viewsonic.com/us/va2719-2k-smhd.html

Is this fine (5ms?). Or should I be worried about the 14ms listing

look at the manufacturer site

There are different ways to measure pixel response time, since the actual time to fully change a pixel from one color to another will vary depending on what the two colors are. Typically, screen manufacturers will advertise "grey-to-grey" response time, which is quicker than the average response time. So this monitor likely has a 5ms GTG response time, and around 14ms average response, which I think is pretty typical for a modern IPS panel. Likewise, those high refresh rate TN panels that may advertise "1ms" response times are also referring to the faster G2G time, and their average response times tend to be in the 5+ms range.

These numbers are all measured by the manufacturer, of course, each using their own methods, so there's no way of telling how accurate they are short of finding a detailed review for a particular monitor that goes into measuring and comparing pixel response between different screens. And most screens don't tend to get reviews that go into that much detail.
