PQ Tester — Frequently Asked Questions
What does the PQ Tester DCTL do?
It outputs a solid HDR patch at a nit level and window size you choose, so you can measure your display's real peak brightness with a colorimeter and see when Automatic Brightness Limiting (ABL) reduces it — the brightness your monitor actually reaches, not its spec.
Is the PQ Tester really free?
Yes — enter your details above and we'll email you the download link. No payment, no catch.
Do I need DaVinci Resolve Studio?
Yes. DCTLs run only in DaVinci Resolve Studio (the paid version); the free version can't load them.
How do I install it?
Drop the PixelTools folder into your DaVinci Resolve LUT folder and restart Resolve. Full steps are in our install guide.
Do I get updates?
Yes — free updates for life. Re-download anytime, or use the one-click PixelTools Installer app.
