REVIEW: Fujitsu P27T-6 IPS Part 19

Scene from the full HD trailer "Ice Age 4", displayed interpolated to full width by the player.

Hence it comes as no surprise that content in SD quality is displayed blurry and pixelated. Still, colours and contrast are proper, but can’t offset the lack of signal quality. The only solution here is to raise the viewing distance.

Video signal processing

Alongside with colourmetric correct display, the picture quality to a substantial degree depends on the capabilities of electronics. Using different signals from SD to HD, we test the quality of scaling and pay attention to a clean, detailed and free-of artifacts display. Filter solutions, especially sharpness and noise filter, are interpreted, too. Also, the deinterlacing of half-frame based signals has got a huge influence to the quality of representation. For testing purposes, we use syntetic test as well as real-world material. Subsequently, we test the judder-free playback of signals between 24 and 60 Hertz within the limits of time resolution of the material. With all this, we cover the playback options that are common today. We also examine circuits for the interframe calculation, as well as the processing of RGB and YCbCr signals.

Scaling

In the video area, only with HD material we have an square pixel aspect ratio. If a monitor provides an explicit 4:3 or 16:9 option in the scaling settings of the OSD, there’s a good chance to display corresponding material correctly.

Our series of test images is based on an anamorph video showing circles, which have to be perfect if the aspect ratio is correctly taken in account (playback via HDMI). With the help of the settings of the Blu-ray player we can simulate all kinds of playback.

The image format settings of the Fujitsu P27T-6 are limited to the options "Full-screen", "Proportional" and "1:1" – there’s no 4:3 setting. Although "Proportional" could mean that 4:3 display was possible, our test didn’t confirm this assumption. If the player is set to "4:3" and the P27T-6 to "1:1", the resulting picture is displayed with an aspect ratio of 4:3, but its content is just stretched to the height of the monitor. With no setting we were able to avoid this stretching. The P27T-6 acts strangely if the video format 1080p/i is set in the player: Regardless of the picture format set in the Fujitsu-monitor, SD media is compressed in height. To avoid this faulty display 480/576p/i has to be selected explicitly in the player. Only then, SD media in 16:9 picture size will be display correctly.

Signal	Undistorted playback
SD (16:9 - anamorph)	Yes (pixel-fine, too)
SD (4:3)	No
HD (720p)	Yes (pixel-fine, too)
HD (1080p)	Yes (pixel-fine, too)

Supported refresh rates

An image refresh rate of 60 Hertz is a common standard for TFT displays. If a monitor is equipped with an HDMI port, 50 Hertz will be supported additionally. Here, the Fujitsu P27T-6 is no exception. The playback of DVD movies is done with 50 Hertz and judder free.
