There is no ITU recommendation concerning subjective tests for video quality assessment in UHD resolution. A clear methodology needs to be established. In this paper we present a subjective quality assessment test of HEVC/H.265 compressed 4K Ultra-High-Definition (UHD) videos in a laboratory viewing environment. We describe the methodology employed, including the setup room based on different parameters such as user position, viewing angle and viewing distance, and the video dataset we used which has been previously employed. Finally, we make some considerations on the experience collected on the methodology and on the fact that the same experiment when conducted in different countries with different languages and cultures may lead to different results.
