CCOHS notes that reflections change the contrast users actually see, making readable text and comfortable scaling more useful than isolated numbers.
Compare the actual reading conditions
The fact sheet explains the difference between dark text on a light background and light text on a dark one, noting that preference remains important. Reflections in a normally lit office reduce the contrast a user actually sees compared with a specification measured in a dark room. A dramatic advertised contrast figure therefore does not automatically describe the experience of reading an ordinary document.
Balance resolution with scaling
A higher-resolution monitor can show more detail, but interface elements may become smaller unless scaling is adjusted. The guidance recommends a comfortable size and generally using the display's native resolution. HDR is more relevant to suitable image and video material than to basic word processing. When evaluating screen comfort, consider the text size, viewing distance, surrounding light and task together instead of treating resolution, dark mode or brightness as an isolated cure.
