Overview
An IPS panel with dense ultra HD pixels makes text crisp and photos detailed on this LG UltraFine, while wide color covers HDR content. The stand tilts, raises, swivels and pivots to portrait.
Sharp text and accurate wide color suit spreadsheets, coding and photo editing at a desk. Refresh rate is standard, and HDR on a modest brightness panel is mild.
Who it's for
Remote workers, coders and hobby photographers will appreciate the detail and stand. Fast shooter players should look at a high refresh gaming monitor.
Pros and cons
- Sharp ultra HD text
- Wide color gamut
- Fully adjustable stand
- Screen splitting app
- Standard refresh rate

Performance notes
High pixel density on a mid size screen makes text and images crisp, though some scaling is needed in the operating system. IPS holds colors steady at angles. HDR depends on panel brightness, which limits highlight impact.
