Frequently Asked Questions Why build a video wall of plasma display panels (PDP)? Plasma monitors require little space. At any wall-video diagonal size, thickness hardly is 10 cm. This is an important advantage not only at placing, but also during transport. Plasma wall gives high contrast and high luminosity and provides excellent image even under strong illumination. The plasma wall visual angle is 160 degrees in both directions, so it is perfectly visible from anywhere. What makes the difference between Infinite and Neodigm plasma walls? Neodigm walls are fix size, consisting of 4 pcs 42” panels. Their control does not require any outer device; they can be operated like conventional TV sets by means of a remote control. Of course, outer control can also be applied if necessary. Infinite walls have a modular structure, operation requires separate control. Neither equipment contains a TV tuner. Can I use plasma wall to watch TV? Yes, of course, but you need an external TV tuner. In order to obtain best quality picture, we recommend the use of a device able to give PAL/NTSC or DVB signal on a good quality output (e.g. DVD writer, PCI card built in a PC, etc). Nowadays, one can buy signal shapers equipped with external TV tuners, which contain picture appraising circuits, so one can watch TV programs on plasma wall in an even better quality. What is the resolution of a plasma wall? The resolution of a panel is 852x480 pixels (WVGA), while the resolution of the whole wall may be maximum 1600x1200 pixels. Using individual control, the resolution of giant walls can approach the total resolution of the panels. Neodigm plasma wall 84” size produces a resolution of maximum 1600x1200 pixel. What picture size can be built of Infinite plasma panels? Optional size and shape wall can be built from Infinite panels. The actual control-software makes possible the simultaneous control of 6x6, that is 36 panels, but using individual control the picture size can be increased however far by increasing the number of panels. A panel’s diagonal is 42” (106 cm), which means that the 6x6 wall’s diagonal is more than 6 meters. Naturally, not only conventional built-up solutions may be implemented, even a 1x6 or 2x4 solution may be carried out, it is only your creativity that sets the limits. What does „seamless Multi-PDP” mean? Conventional plasma monitors have got quite a thick rim, which makes them unsuitable for operating as video wall. Infinite and Neodigm panels are produced with a special manufacturing technology, which helps reducing the rim to 1-2 mm size, thus the thickness of the joining strip does not exceed 5 mm. How many sources can be displayed simultaneously on the Infinite plasma wall? The Infinite panels are equipped with different video inputs, through which they can receive and display 5 different signals at the same time. The 5 inputs are not of same rank. Only three of them are able to receive high resolution (HD) signals, the other two can only handle conventional PAL and NTSC signals. The displayed picture can be modified optionally. What is necessary for the operation of Infinite plasma wall? Basically three things are required: plasma wall itself, a control PC and some signal source. To be mentioned that the plasma wall consumption can be quite high (3-400 W per panel), therefore appropriate power supply is needed. Should you wish to display one source on more than four panels, a signal amplifying distributor is needed. (See next question). How to connect the signal sources to the plasma wall? Each panel has input and output, so monitors can be row-connected and only the first monitor has to be connected to the signal source.. The signal gets from the first panel to the second one and so on. In case of Infinite panels, it is possible to build a wall larger than 2x2, but meanwhile it is to be noted that a distributor amplifier is required per every four panels, so that each device can receive an adequate powerful signal. Practically, this means that in case of a 3x3 wall, a 3-output distributor amplifier will be required in order not to charge more than four panels on an output. Can I connect a HDMI-output device e.g. DVD/HD-DVD/Blu-Ray player or HDTV indoor equipment to the plasma wall? In case of plasma wall built of Infinite panels, yes, because the device is equipped with a DVI-D (HDCP) input too, which is „permeable” to HDMI standard by means of a converter. Neodigm plasma wall has no such an input, so in case of the above mentioned players we suggest using the component input. What is the control PC? The control PC is a conventional computer operated by the control software. By all means it needs a RS-232C port (through this the PC communicates with the plasma wall) and a Windows XP operational system for the control software. In case of buying the plasma wall, we provide the software free of charge. Frequently Asked Questions list was compiled from the most frequently arisen questions.
