For a judder free playback of Blu-ray movies, a refresh rate of 24 Hertz or the multiple thereof is needed, which is supported by few TFT monitors only. But the Fujitsu P27T-6 is an exception here: Although we didn’t find a hint in the data sheet, 1080p24 playback is possible.

The Fujitsu P27T-6 supports 24 Hertz.

Deinterlacing

Deinterlacing is the conversion of a video signal available in fields to a series of frames. Our report "Make 1 out of 2 - Deinterlacing" gives further information.

The Fujitsu P27T-6 is able to playback half-frame based signals (480i, 576i und 1080i). In our test we check if signals with 2:2 cadence (PAL signal) and 3:2 cadence (NTSC signal) are recognised and processed correctly by the deinterlacer.

As is to be seen in the test video, the deinterlacer of the Fujitsu P27T-6 isn’t able to process signals with 2:2 cadence correctly. Instead, it scales them to panel resolution via simple field scaling. Only signals with 3:2 cadece are properly processed.

… whereas 3:2 signals are detected and processed correctly, …

… and video material likewise.

At least, the Fujitsu P27T-6 is able to playback half-frame based signals with 3:2 cadence. However, in Europe, where PAL signal with 2:2 cadence is the standard, this doesn’t help. In general, it is always recommended to provide a TFT monitor with frames to avoid unnecessary quality loss.

Colour models and signal level

The importance of an attuned signal level of the playback is often underestimated, but it is a crucial criterion for correct display. Possible coordination problems result in either a significantly reduced tonal range or in a washed-out, matt picture missing full white and black.

At the playback via RGB, the Fujitsu P27T-6 demands PC levels (range of 0 to 255 per channel) and hence uses the complete tonal range. The monitor also recognises YCbCr colour models and processes them correctly, reaching Video levels (range of 16 to 235 per channel).
