Here, we have one of its latest models - the XP17 TempAR 8ms 17in LCD. This is the latest incarnation of the XP range complete with an 8ms response (stated as a grey-to-grey, rise plus fall time) and a tempered glass overlay that gives the XP17 a high degree of resistance to knocks and scratches. In fact, Shuttle claims that the glass it’s used is equivalent to and possibly greater than 8 on the Moh scale of hardness. To get an idea of what that means, this glass layer has a similar level of scratch resistance to that of topaz, with diamond occupying the top spot in the table with a value of 10.
