Make sense of the details
Choosing the LG 34CB99 Ultra HD 4K
The 86.4 cm (34") display is specified at 3440 x 1440 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
Compare the specification with your intended use and read the original reviews for performance, comfort, reliability and other qualities that a specification sheet cannot establish.
Before choosing this monitor
- Measure desk depth, viewing distance and arm clearance.
- Check computer output, monitor input, cable and dock as one chain.
- Choose a stand or arm with the adjustment you actually need.
- Use independent tests for brightness, uniformity, text and motion.
