I was checking out DisplaySpecifications.com to compare the two monitors (the HP X32 and this Dell G3223D). It turns out they are both using the same excellent LG LM315WQ1 panel. The only differences are the presentation (i.e. features). So, you have to decide if it is worth paying $70 more for the "features". Here are the differences.

Dell G3223D:

Panel is 0.65 mm thinner width
Panel is 2.3 mm shorter height
Weight with stand is 8.5 kg (18.8 lb)
Has 2 HDMI 1.4 ports
Has 1 USB Type-C input port (input for video)
Has 2 USB Type-A output port
Has NVidia GSync
Has swivel of 30 degrees left/right
Has 5 degree down tilt, 21 degree up tilt
Operating temperature range is rated as 32F-104F
Operating humidity is 10%-80%
Comes with USB Type-C cable

HP X32:

Panel is 13 mm thinner depth
Weight with stand is 7.9 kg (17.4 lb)
Has 1 HDMI 1.4 port
Has rotation of 90 degrees to portrait mode
Has 5 degree down tilt, 20 degree up tilt
Operating temperature range is rated 41F-95F
Operating humidity is 20%-80%


So, basically what it comes down to is $70 more for 2nd HDMI input, USB, swiveling, NVidia G-Sync and no rotational pivot. Swiveling doesn't matter too much if you are putting this on a VESA mount, whereas rotational pivot would still function and be useful.


Edit: I would like to note that DETAILED reviews of the monitors reveal similar SDR peak brightness - 389 nits vs the advertised 400 nits. Which just means that the technical performance will be the exact same, and the numbers below, for the X32, apply to both panels (comes from a YouTuber who does in-depth reviews):

Billed vs Real:
SDR Brightness: 400 nits - 389 nits
Contrast: 1000:1 - 908:1
Avg response rate: 1 ms - 5.52 ms
HDR: Real HDR400 - Fake HDR400
Real HDR brightness has 600+ nits, 70%+ gamut coverage, 500+ dimming zones, 50,000+:1 frame contrast, 5,000+:1 checkerboard contrast.
This panel has 455, 66.9%, 8 zones, 4732:1 and 795:1. So very poor HDR performer

When's the 27 inch one coming on sale?!
