I examined the 734pm’s brightness, distinction ratio, and colour protection utilizing our normal take a look at gear: a Klein Okay-10A colorimeter, a Murideo 8K SixG sign generator, and Portrait Shows’ Calman Final for Enterprise calibration software program.
HP charges the 734pm’s luminance at 400 nits (candelas per meter squared), and in our testing, it simply cleared that, at 492 nits. The panel has a VESA DisplayHDR 400 score. I measured its HDR luminance at 514 nits and peak HDR brightness at 562 nits.
The 734pm turned in a wholesome 1,974:1 distinction ratio. HP charges its colour protection at 100% of the sRGB house and 98% of Show P3; it successfully matched each of those with 98.7% protection of each sRGB (see the chromaticity chart under) and DCI-P3. Show P3 is Apple’s implementation of DCI-P3 and is similar to that colour house.

I additionally examined the 734pm’s Delta E (dE), a measure of colour accuracy, specifically the distinction between the hue of a displayed colour and the colour enter the monitor acquired. The decrease the dE, the extra correct the colour. A mean dE of under 2 signifies colour correct sufficient {that a} informal observer could also be unable to tell apart any variation between the colour on the display and the meant (supply) colour. I measured the dE at 1.08. That is a wonderful determine, notably as a result of the 734pm is pitched as a productiveness monitor fairly than a devoted creator-centric monitor, and the corporate makes no particular declare in regards to the show’s dE.
Within the ad-hoc, experiential a part of our testing, I considered chosen video clips in addition to our picture suite on the 734pm. Pictures have been brilliant, with realistic-looking colours and good retention of element in each mild and darkish areas.
