HDR not for everyone some people sensitive to bright light

Nevertheless, it remains a source of light challenging to manage, given its dynamics and its associated over-heating and glare risks1,2. Excessive brightness from daylight in workplaces can indeed lead to discomfort glare which, if prolonged or recurrent, might reduce occupant well-being, mood, and performance3,4. Discomfort glare causes visual irritation or annoyance without necessarily impairing the vision5. It has been studied for several decades and the prediction models resulting from the conducted user assessment studies are nowadays able to provide a reasonable estimate of visual discomfort for a group of observers6.

Results: : We found that of the five types of phototoxic effects identified by the ICNIRP (thermal damage to cornea, lens and retina, and photochemical damage from UV and blue–light), photochemical damage from blue–light is the only type in which there are non–negligible effects of radiation. Furthermore, we found that potentially hazardous blue–light radiation of HDR displays are well below limits established by the ICNIRP for phakic subjects.

The key phrase is “for some users.” A person who runs SDR at 10% brightness may find HDR uncomfortable even at modest settings, while another person may prefer HDR because it gives clearer depth and less muddy shadow detail.

With HDR, there is no way to turn ... Click to expand... ... Unless you have light sensitivity, HDR monitors today don't get anywhere near bright enough to be anywhere close to what you see when you poke your head out of the door on a bright summer day....

If you enable HDR in Windows and then observe this kind of normal SDR content, it will very often look bad. Some monitors handle this better than others and could look fine, but in our experience the majority of screens end up looking washed out, with colours and brightness that don’t really look right.

Warning: NSFW Walter Volpatto, Sr. Colorist, Picture Shop, argues that HDR causes discomfort because, unlike in real life where the scene before us occupies our entire field of view, we’re watching TV in a dark room where the picture occupies a much smaller field of view, forcing our pupils to open up, making the image…

High Dynamic Range (HDR) technology enhances visual experiences with brighter highlights and deeper shadows, mimicking how we see the real world. While excessively bright screens can cause temporary eye strain, HDR itself isn’t inherently harmful; proper viewing habits, screen settings, and ambient lighting are key to enjoying its benefits safely.
