REVIEW: Fujitsu P22W-5 ECO IPS Part 14
Deinterlacing denotes the conversion of a half-frame based video signal into a series of full frames. The Fujitsu P22W-5 can process half-frame based signals (480i, 576i, 1080i), which are combined to form full frames with the aid of an integrated deinterlacer. Further information is available in our report: "Make 1 from 2" - deinterlacing.
480i and 576i signals are displayed by the Fujitsu P22W-5, but the result is a juddering image display. Furthermore the P22W-5 cannot carry out correct deinterlacing with these resolutions, neither for signals with a 2:2 cadence nor those with a 3:2 cadence. Instead, the restoration of a series of full frames is achieved by means of simple field scaling, which is expressed in the form of pronounced combing effects on the rostrum.
Because of the very jumpy picture, we put the Fujitsu P22W-5 through the deinterlacing test with a resolution of 1080i. Although the juddering has not yet completely disappeared, it is considerably less pronounced. Also at 1080i, a 2:2 cadence is not reproduced correctly and the processing of the 3:2 cadence signal, which is correct according to the test video, is questionable. Here, the Blu-ray player may also be the reason, since it must first chance the signal present into full frames, upscale it and then reproduce as half frames for 1080i display.
No functional film mode deinterlacing for 2:2 signals.
3:2 signals are processed correctly with the aid of the player …
… and so is video material.
The Fujitsu P22W-5 makes it possible to play back half-frame based signals, but it is not capable of doing so. Display is very jumpy, especially at 480i/576i and is completely unsuitable for watching films. 1080i also fails to deliver a satisfactory result. Therefore, we recommend that only full frame based signals (480p, 576p, 720p, 1080p) are played back on the Fujitsu P22W-5 and that the deinterlacing is left to the player device.
Correct scaling in video material is almost as important as a correct resolution in video games. The output should neither be distorted nor truncated. Since it is not possible to make such extensive graphic adjustments here as are possible on the PC, the result can only be influenced to a limited extent.
If the Fujitsu P22W-5 is connected with an external player device via its HDMI input, the user can select from the image formats "Full screen", "16:9" and "4:3" in the OSD.
A test video should show whether or not it is possible to receive a correct aspect ratio and untruncated display with any settings on the monitor or player device. If not otherwise stated, playback was in 576p50.
Full screen (software player: Full screen)
As a comparison, we first displayed the test video on the PCD with a software player, scaled to full screen. The circles are not distorted and the image is also not truncated. This is how the result should look for playback via an external player.
Monitor: "Full screen" (Player: "16:9")
Since the aspect ratio of 16:10 on the Fujitsu P22W-5 is too high for 16:9 image material, this is displayed as slightly stretched. In addition, display is somewhat truncated in width, although not much. Apart from the truncated width, this display is correct with the aforementioned settings on the monitor and player.
