Which iMac to buy for no eye problems at all?

Unfortunately I don't know of any device (Monitor, PC, Apple computer, Smartphone) that universally causes no problems for anyone. Also I have had 2 copies of the same product where one was fine and the other unusable. This is a highly unique disability and you need to test for yourself. Good luck

lillo9546 If I were buying a computer now, I would buy a refurbished small form factor desktop Fulfilled by Amazon. Then I would install Ubuntu and pair it with the monitor(s) of my choosing. However, most of those boxes come with Windows 10 Pro pre-installed, so I'd probably try that out first to see how it is. From what I've read on here, Windows 10 generally is preferable to Linux for some users experiencing eye strain.

ensete Right now I'm using the latest Ubuntu official release. I used to use Ubuntu Mate. Are you saying you actually notice an improvement in your eye strain using Linux Mint vs most other distros? Maybe I should install the latest Mint?

In terms of usability, I like the Ubuntu I'm using now, but I don't know enough to understand how Mint or other distros may provide a more comfortable viewing experience, particularly regarding text.

Right now with my desktop scaled up and my browser windows all zoomed, text does seem very clear and readable. I run a dark theme both in the OS and in my browser windows, so my background here is black and my text is a custom off-white color with reddish-pink hues.

I'm also considering buying a refurbished small form factor desktop because my little MSI Cubi seems a little overworked with my two monitors. I have a little external fan on it, circulating some air through holes in the unit, helping to keep it cool, but I can still hear the little fan inside working too hard. The CPU cores are just above 50 Celsius. I have 12 GB of ram in there. It's served me well since I bought it.

Also -- You say the monitor doesn't matter as much as the software, but every time I move a window from my low haze screen to the matte screen, I'm pretty shocked by how much gloss and contrast it loses. The low haze screen looks better in Limited than does the matte screen in Full RGB.

Once again I have to say HP has a wonderful IPS release in the low haze 25er and 25f models. Really good product for what it is.

Edit: Cranking up the contrast on the matte unit has helped significantly. The low haze coating seems to allow better contrast. Therefore I'm curious to see how I like the VA unit I have coming in the mail. However, I still think the low haze unit looks better and is kinder on the eyes.

Linux distros can have different desktop environments. Linux Mint with the Cinnamon desktop was pretty good for me. Linux mint with xfce was bad.

If it works, I wouldn't change it.

Just in my experience, I have some screens that are bad al the time, and I have other screens that I can make good or bad depending on what is being shown on them or what is driving them.

Also, I havefound several times that different physical versions f the same device act differently. Many, many times I have had a smartphone that works fine for me, but another identical version is unusable. I learned that consumer electronics almost all use different components from different manufacturers in the same product line. So finding one iMac that causes you no issues is no garauntee another iMac won't.
