Benitron When choosing a new monitor, always start with a proven good source (for example, a desktop, laptop, or tablet) that does not strain your eyes when used with a known good screen. This is important because if the source itself causes strain, you cannot be sure whether the issue is with the source, the monitor, or both. If none of the monitors you try (regardless of technology, panel type, or age) seem to work, it makes sense to focus on the source first.
You mentioned using a laptop, so I’d be extra cautious about drawing conclusions when connecting a good laptop with a good built-in screen to an external monitor. For example, I never had any issues with my 13.3" laptop that used the UHD 620 graphics chip (which tends to be easier on the eyes compared to something like Iris Xe). That said, I believe I had adapted to some level of dithering, and the screen size was small enough for my eyes to tolerate a slightly degraded signal.
However, when I connected the same laptop to a very good monitor (Dell 2407WFP), I couldn’t fully adapt to it. This shows that we can sometimes tolerate smaller screens even if the signal from the source is not entirely clean.
Also, keep in mind the role of FRC and built-in image enhancements. FRC can usually be avoided by choosing a true 8-bit panel, but there is also the controller side to consider. Some monitors may have built-in enhancements or processing that cannot be turned off, which can also contribute to discomfort. So it is worth keeping an eye on that as well.
As for monitor models, there’s no simple answer. It mostly comes down to testing what others have reported here on the forum or in the Telegram group. Buying second-hand is usually the safest approach, since you can resell it for the same or a similar price if it doesn’t work out. Personally, I’ve stepped away from external monitors for now, as even the best ones that actually work for me tend to cause general eye strain much more quickly than laptops. It’s not the severe symptoms like nausea or migraines, just quicker fatigue, likely due to the screen size alone.
