Refresh rate defaults to 14ms but can be adjusted down to 5ms G-t-G. It is not a gamers display as it does not support FreeSync or G-Sync.

Brightness is 300 nits (we found 324 nits across the entire screen), and colour uniformity is accurate across the screen.

Colour accuracy – spot on

HP individually colour calibrate the HP38c monitor to 98% sRGB and 99% Rec.709 modes and include a report. You can select these or play worth custom modes. But the Delta E (accuracy) is very good in both modes so why bother?

HP Z38c

For viewing modes, you get toggles for Night, Low Blue Light, Reading, HP Enhance+, and Photo.

sRGB reproduces all of the colours you could hope to see in real life on an LCD. Our tests show 100% – slightly more than claimed.

Rec. 709 colour standard was created by ITU (International Telecommunication Union) for TV, movie and A/V industries to ensure all HD equipment including displays, DVDs, and Blu-rays uses the same colour gamut, resolution, frame rate and video specifications. Again, our tests were just above claimed.

While still and video editors might want 100% DCI-P3 that only comes in reference monitors several times the price. We estimate that it is about 78% Adobe RGB.

All that is complemented by a low glare screen that rejects office light and reflections admirably.

It comes with a USB-C cable, Display Port cable, HDMI cable and documentation.

GadgetGuy’s take: HP has done it again

First, th HP Z38c is aimed squarely at business. There are no tricks like FreeSync, no speakers or sexy red bands you find on some monitors.

No, it is subtle, has a three-year warranty and does its job extremely well. It is very colour accurate, has heaps of adjustments and made well – as we expect from HP.
