Why Trust SubInsider

Clear, Accurate Monitor Guides You Can Rely On

SubInsider is an independent knowledge base focused on one thing: computer monitors. Every guide is written by our editorial team, checked against primary sources, tested where we can, and dated so you always know how current it is. No fluff, no hidden agenda, just answers that help you understand and get the most from your display.

Independent and Unbiased

We have no manufacturer affiliations, and no brand pays for a favorable verdict. Our only goal is to help you understand monitors and make good decisions.

Tested and Researched

Guides combine hands-on testing with manufacturer documentation and recognized standards, such as VESA, rather than recycled summaries from elsewhere.

Primary Sources, Cited

When a claim depends on a source, we point to it, so you can check the facts yourself instead of taking our word for it.

Kept Current

Monitors, operating systems and software change. Every guide shows a published or updated date and is revised as things move on.
