Screen protector for 24 inch monitors

The Corn Electronics filter hangs on widescreen displays measuring 21.5 by 12.6 inches with a 16:9 aspect ratio. It targets office workers and home users who spend long hours in front of a panel and want to reduce blue light exposure without permanent adhesives.

Thermals noise and power

The acrylic sheet adds no active cooling, draws no electricity and produces no audible noise. It simply rests on the monitor frame, so system thermals and power consumption remain completely unchanged during normal use.

Blue light filtering range

The protector blocks harmful wavelengths between 385 and 445 nanometres while transmitting beneficial light above 445 nanometres up to 500 nanometres. It also filters 99 percent of UV output. Buyers who need a privacy filter or a touchscreen overlay should look elsewhere.

Questions about this item

How do I hang the 21.5 x 12.6 inch frame on my monitor without trapping bubbles?

Clean the screen, peel both protective films from the acrylic panel, then hook the frame over the top bezel; the paste-free design leaves no adhesive residue and prevents bubbles entirely.

Will the blue-light coating wear out and need replacement over time?

The filter is built into the acrylic material itself, so it does not degrade or require periodic replacement under normal use.

At what point does colour accuracy suffer during long editing sessions?

The panel transmits beneficial wavelengths above 445 nm while blocking 99 % of UV and harmful blue light between 385-445 nm, preserving colour fidelity for extended work periods.
