Frequently asked questions
Why does my 144 Hz monitor report about 60 Hz?
The active rate is often limited by operating system or GPU settings rather than the panel itself. Record the browser estimate first, then check your display settings.
What does ghosting look like in practice?
Moving edges can leave faint trailing or smearing behind them. What feels acceptable depends on the game, the response-time setting and your eyes, so compare settings yourself.
Do I need a special cable for high refresh rates?
Cable and port bandwidth can limit which modes your system offers. If an expected rate is missing, try a cable rated for it before judging the panel.
