I just bought a 23" widescreen LED monitor for my Windows PC, I always use CRT monitors, it is the first time for me to work on a LED monitor.
I am a low vision, so I always increase DPI.
Is increasing DPI harm the LED monitor?
Thanks in advance.

3It is not harmful to the monitor to change any settings in Windows. Settings that aren't supported by the monitor aren't available.– Christofer WeberCommented Nov 13, 2016 at 13:20

24a LED has no DPI, because it's just a lamp– phuclvCommented Nov 13, 2016 at 14:25

1heh. That's why my answer has LCD/LED. Technically most common LCD monitors now are TN with LED backlight. Older monitors would have CCFL backlights, and higher end monitors would be IPS or VA LEDs....– Journeyman Geek ♦Commented Nov 13, 2016 at 14:29

1As others have said, you really can't change the display resolution effectively, as it's built in. What you should do for low vision is to use larger fonts. And of course use a high-contrast color scheme.– jamesqfCommented Nov 13, 2016 at 18:01

Increasing your DPI makes your display items look smaller. I believe its entirely a software setting and shouldn't damage anything.
Changing your resolution results in terrible display quality on LCD/LED monitors. Depending on your OS, its typically a better idea to change your display scaling and font settings to fit your needs.
Increasing Display scaling literally goes "render 1 pixel as 2x2 pixels" and as far as your monitor goes, its still rendering the same resolution.
None of this would damage your monitor or shorten its life (and most modern monitors won't show unsupported resolutions anyway) but its not the best way to ensure readability.

8Yeah, I think we have a terminology issue here. increasing your DPI would make things smaller. Decreasing it makes it bigger. Unless he's talking about DPI scaling...– Journeyman Geek ♦Commented Nov 13, 2016 at 15:08

Not really, he's increasing the DPI of his monitor, not of the images he displays. Just try it yourself, easy to see. Pun intended. Commented Nov 13, 2016 at 15:13

11No, increasing Dots Per Inch makes more dots fit in an inch of length, therefore implies smaller dots.– loa_in_Commented Nov 13, 2016 at 16:22

4@loa_in_ Increasing the DPI setting makes the system think the dots are smaller, therefore it draws everything with more of them, making everything bigger. The actual size of the actual dots can't change because it's a physical property of the monitor's design. Commented Nov 13, 2016 at 18:01
Some of the discussion seems to reflect semantic differences. Just to avoid confusion in terminology, on LED and other flat panel displays, the pixels are fixed, manufactured in a specific physical grid. Everything is displayed using those pixels.
If you change resolution or scale the image, you're just mapping what gets displayed onto those pixels (or using fewer of them). You can't damage it by changing what you display.
Changing DPI is really only changing how the content is mapped to the physical pixels. What would be a single pixel at the native resolution might get interpolated across multiple pixels to make it look larger, or detail that would be displayed in multiple pixels at the content's native resolution "averaged" together to squeeze it onto fewer pixels.

It's not harmful in most of the cases, but - instead of CRT monitors - where simple but efficient electronics was just shutting down the tube when it was an unsupported mode, in LED monitors there are no such a simple fail-safety. In 90%+ cases no unsupported settings will be displayed to you to tweak, but sometimes it happens, especially on laptops(as of my experience). So - just check the monitor's manual and - if there's no data - just write to the support. I did it once with my ACER monitor: the support was very quick to reply to me with full hardware specs including the chips used list!
