Computer Monitors for Photosensitive Readers?

[MarjaE]

I have far worse trouble with red light than blue light. I have tried using blue sunglasses to reduce red light, and tried tweaking color settings, each helps, but they only do so much.

I can't watch the videos without more migraines, so can't judge the Mira.

You'll never be able to judge monitors over video - because there are no "flicker-free" ones.
You can only experience them live.

Agreed, impossible.

Also showroom lighting is nasty!

I have my screens arranged so no daylight is on them and the room light is offset so not reflected.
Benq 24" BL series
Brightness 8
Contrast 25
Best screen I've used other than the 800x400 ACT Sirius 1 (Mono green with black mesh cover) in 40 years.
Exact model BL2420PT 24"
I bought a 2nd one for the PC with scanner and video editing. The first is for the laptop.
Very good up/down, tilt and rotate as well as portrait and landscape. I'm running 2450x1440, HIDPI = OFF and the text is fine at 100% in web and LO Writer with DPI set to 112 on Linux. Setting 96 to 120 is also OK depending on your eyesight.

It is common to get vision problems while staring at the screen, that is why I never recommend using a cheap monitor, instead get a good monitor with proper eye-care features.

The "eye-care" features are a total gimmick. Simply get a screen with as low gloss as possible, adjust settings and ensure no daylight or lamps are reflecting off it.

Since the June post I got an Samsung 28" 4K screen, but found it a little large, so moved it to the PC with a scanner and replaced a 19″ CRT with the Benq. I use a 24″ 4K LG screen now and with the settings all turned way down it's almost like premium coffee table coloured book paper. Almost no reflections (positioned so no room lights or daylight reflecting), no flicker, no backlight bleed. Brightness =7, Contrast=42 (max is 100).
All stuff like ecomodes, dynamic contrast etc all turned off on TVs and monitors as they degrade the quality.

Shiny high gloss screens are cheaper to make and can look nice in a showroom. They are a disaster.

28" is too large? What would you think of my 65" LG C1 OLED TV?

Great for movies!
We do have 40″ HD and 43″ HDR, and a 55″ 4K HDR tvs for watching TV, Satellite, VHS, DVD and Bluray.

A 65″ 16K or better might replace 4 off 32″ 4 K screens. A 32K 65″ would be equivalent to 9 off 21.7″ screens at about 3.6 K, so really the DPI would be poor even with an 8K 65″ screen as a monitor. The 28″ 4K DPI was a bit low which is why I swapped to the 24″ 4K. The 24″ 4K DPI is just OK. You'd want 24″ 16K or 12″ 4K to be wanting the HDPI setting on a desktop (Apple Retina mode, 4 pixels for each dot, so no cleartype or similar tricks).

16K is like 480ppi. You don't need that, for reference all of Apple's Retina Macs are sub-300 ppi. Even most of the iPads are (all except Mini). It's only worth it on screens with pentile arrangements of pixels because they look bad otherwise which is why it's so common on phones. Since like no monitors use pentile arrangements and you don't sit close enough it doesn't really matter. And with Windows and fractional scaling 28" 4K is IMO pretty good.

Mac level high DPI you want a 21" 4K or 27" 5K but I don't think it's worth it.

Depends on screen size.
A 65″ 4K screen is really poor DPI.
65″ 3840 x 2160 = 67.78 dpi, poorer than almost all 1990s CRTs!
Fine at family viewing distance with 1:27 movie like Ben Hur. Rubbish for reading glasses or normal text reading distance.

I may though have made some mistakes in the arithmetic. Certainly compared with 23″ 3840 x 2160 (AKA 4K) you'd need 10,852 x 6104 pixels, which I suppose might be called 11K.

23″ 3840 x 2160 = 191.56 dpi, not enough for HDPI setting.
65″ 7680 x 4320 = 135.56 dpi, typical 8K
65″ 10,852 x 6104 = 191.56 dpi dpi
So I think 16K would be about 15360 x 8640 = 271.13 dpi, good enough to turn off ClearType or similar.
480 dpi would allow HIDPI setting and need about 27192 x 15295 which marketing people might call 28K or 30K

Cinema has various different resolutions called 4K, 8K, 16K etc and the normal 4K, 8K 16K of domestic monitors are simply multiples of the 1920 x 1080 (HD or 2K) 2K may also refer to resolutions like 2048 × 1556 (full-aperture), 2048 × 1152 (HDTV, 16:9 aspect ratio) or 2048 × 872 pixels (Cinemascope, 2.35:1 aspect ratio).

There are 2560 x 1440 monitors. That should have been entry level HD. The 1440 x 720 is hardly HD and PCs often had 1600 x 1200 4:3 (common by 2002), till TV panels for 16:9 took over at 1920x 1080, few screens had 1920x1200.

4K = 3840 x 2160 (UHD or UHD-1)
8K = 7680×4320 (UHDTV-2)

There may not be a 16K spec.
