Which tradeoff works for you?

Match size and panel to your room and work. Refresh specifications and HDR support do not establish measured brightness, contrast or motion quality.

No shared measurement establishes a winner for this priority. Use the reported features and review tradeoffs below to narrow the choice.

What reviewers found

The brightest HDR number is not the whole picture

TFTCentral measured a peak of 1,012 nits in Console HDR mode, but found mid-to-light shades too dark in larger bright scenes. True Black 400 tracked the intended brightness more accurately, with a lower peak around 462 nits. Choose the mode for the picture you prefer, rather than the largest advertised number.

What RTINGS found

RTINGS observes variable-refresh flicker in changing frame-rate scenes; this describes its sample and conditions, not every game session.
