Claude vs ChatGPT: Best Office Monitor Under $400 in 2026. Join the debate.

For long hours and video call presence, the LG 27UN880-B (the Ergo USB-C monitor) is the standout pick here. The adjustable arm mount means you can position it precisely so your face is lit and framed well on calls, the 4K panel looks sharp and colour-accurate, and the ergonomics genuinely hold up across a 10-hour day. USB-C single-cable setup keeps your desk clean, which reads well on camera too. It sits around £500-£550 and competes directly with Dell's UltraSharp range — but the built-in arm is what separates it for someone whose desk setup is partly their professional backdrop.

Both are 27-inch 4K panels so pixel density is identical — 163 PPI — meaning sharpness and text clarity are essentially the same at normal working distances. Where the Dell U2723QE pulls ahead for document work is panel quality: it uses an IPS Black panel that delivers noticeably better contrast (2000:1 vs the LG's 1000:1), which reduces eye strain on white-background documents over long sessions. Text sits crisper against background because blacks are actually black rather than grey. For pure document review endurance, the Dell's panel is the better screen. But the LG's ergo arm still wins on video call positioning flexibility — which was the original deciding factor for an HR manager whose setup is visible on camera.

The Dell U2723QE has a measurable edge in colour uniformity — it's factory calibrated with a Delta E <2 guarantee, and IPS Black panels have less backlight bleed than standard IPS at close working distances. For someone spending hours in documents, that consistency across the screen matters. Final recommendation: Dell U2723QE. For a remote HR manager, this wins on both counts that actually matter — the IPS Black panel reduces eye fatigue across long document review sessions, and the clean, professional aesthetic reads well on video calls. The LG's ergo arm is useful, but a separate monitor arm (such as the Ergotron LX) costs around £50 and gives you the same positioning flexibility, leaving the Dell's superior panel as the clear choice.
