Two monitors, one strains my eyes; both are TN monitors.

[Matthew_Lagster]

I'm having troubles with a TN monitor that I was going to set up to use for my desktop pc. I can't look at it for more than 5 minutes without having to take a break, which is obviously not ideal when I'm going to be using it for several hours every day.
In comparison, my laptop, which I'm assuming is also a TN monitor due to the viewing angle, causes a negligible amount of eye strain.
Additional information: Both monitors are LCD and the problem might be the type of backlighting used in the standalone monitor for my desktop. Turning down the brightness or messing with the settings of the new monitor does not help whatsoever with the problem.

I have money to spend and will gladly do so if it means getting a good screen I'm able to look at. If you know what the problem might be, please do inform me.

Note: I usually use my pc in a fairly dark room, but I can use my laptop for hours without much eye strain regardless.

Look for your model name and number online for a calibration setting if you can't measure that manually. Also many monitors / TVs will ship in "torch mode" which is very bright and is visible from across a showroom. Turn your brightness way down and adjust other settings from there.

Your laptop will generally be trying to balance power (assuming you are on battery), so won't be set as bright (requires more power)

Also, make sure you are using a digital connection to avoid VGA blurring, and use the panels native resolution.

Should have included it in the original post, but messing with the settings or turning down the brightness of the new monitor does not help with the problem. I have edited the post to inform others.
I also have my laptop on 100% brightness and I'm not using battery mode.

If your new monitor is gaming-oriented, it may be using strobed backlight to reduce blur and some people have problems with that. On some monitors, this feature can be disabled to run the backlight at constant current/power/voltage instead.

Old LED screens had problems with PWM. Modern ones are flicker free and manufacturers will say if they are. However, I've also used the flicker-free LED BenQ gw2270 and got headaches! I think it's because it's an inferior screen.

I now use a Dell s2240L and it's perfect. It's not available now but try the semi-glossy s2318hx at http://www.dell.com/en-us/shop/monitors-monitor-accessories/ar/4009?appliedRefinements=2829 Select the country at the bottom). Or the 24” s2418x. They are IPS screens so color looks amazing. Dark scenes are stunning.

I have the blue channel reduced to about 37% and the red and green about 50% to create a low-blue-light mode with the brightness at 33%. The sharpness is set at 100%.

On Ebay you can search for “VESA Mount Adapter for Dell”.
