To try to better understand how long a TV should last, we're running 100 TVs through an accelerated longevity test for the next two years. We've just posted our 1-year video update with our latest findings on temporary image retention, burn-in, and more!

Test Bench 1.2


See previous 1.1 changelog.

See next 1.3 changelog.


Picture Quality

  • Added objective tests for 'Specular Included' reflections and 'Specular Excluded' reflections in the 'Reflections' box.

  • Moved 3D support to the 'Input Specifications' box due to declining availability.
  • Changed scoring curve and weightings for 'Temporary Image Retention' test
  • Added new 'Risk of Permanent Burn-in' test to penalize TVs susceptible to burn-in with static content.
  • Added 'Color Temperature' to 'Pre-Calibration' and 'Post Calibration' tests.


  • Added new stutter test to grade TVs on how smoothly they can display low frame rate content.
  • Added new variable refresh rate test to support FreeSync, G-SYNC, and HDMI Forum Variable Refresh Rate.
  • Added new flicker free test for those who are sensitive to flicker or want the smoothest motion.
  • Added new Judder-Free 24p via Native Apps test

  • Added new test for 4k @ 120Hz input lag and Variable Refresh Rate input lag.
  • Added new supported resolutions test for 1440p @ 60Hz and 4k @ 120Hz.
  • Added new test for Wi-Fi support, including frequency band (2.4GHz and/or 5GHz).

Usage ratings

  • Added strikethrough for HDR usage ratings on TVs which don't support HDR.
  • Added 'Stutter' test to 'Movies' rating
  • Added 'Permanent Burn-In Risk' to 'TV Shows', 'Sports', 'Video Games', 'HDR Video Games', and 'PC Monitor' rating
  • Reduced weight of 'Curved' in 'PC Monitor' rating

Notable changes

  • OLED TVs (LG B7, LG C7, LG E7, Sony A1E) reduced in 'Movies' and 'Video Games' ratings due to stutter with low frame rate content
  • OLED TVs reduced in 'TV Shows', 'Sports', 'Video Games', 'HDR Gaming' and 'PC Monitor' ratings due to risk of permanent image retention
  • Sony TVs (Z9D, X940E, X930E, X900E) increased in 'PC Monitor' ratings due to 1440p support
  • Some TVs (most notably the LG SJ9500) changed 'HDR Movies' and 'HDR Gaming' ratings due to fixed 'Color Gamut' calculation
