New monitor checklist: what to check after setup

Updated · 13.10.2026 · MonitorTest

Verify a new display’s setup, pixels and motion. Document repeatable symptoms together with the settings used.

Verify the unit and conditions

Keep packaging while deciding whether to retain the unit. Compare the model, stand and accessories with your order. Inspect the unpowered surface in ordinary light without pressing the panel. Use a stable surface and follow the manufacturer’s handling and cleaning instructions.

Compare pixels and panel appearance

Select the native resolution and 100% browser zoom for patterns. Inspect black, white, red, green and blue in turn. Recheck a fixed point against a clean surface and different content. Look for broad patches or bands on grey and white. Compare corner glow from normal seating, at comfortable brightness and different angles; a dark phone photo alone is not proof of a fault.

Check the connection and motion

Compare small desktop text, the browser and your everyday applications. Start with the recommended resolution and keep system scaling comfortable to read. Blur in one application alone does not establish a defective panel. Hold other conditions fixed when changing HDR or overdrive. Judge ordinary content rather than assuming the highest setting is best.

Record findings and understand limits

After a normal session, try sleep and wake. If a symptom appears, repeat with the same cable, content and brightness before changing just one variable. Distinguish “seen once” from “repeated under the same conditions”. Keep packaging, purchase documentation and settings notes. This checklist does not certify every feature; report repeatable problems to the seller with your record.
