SN-4610-1080 BayCat Startup tips

• The DVI input on the 46” LCD BayCat is a high bandwidth (165MHz, rather than the usual 124Mhz,) “single link” which typically restricts DVI to 1280x1024, so it can support the Bay Cats native resolution of 1920 x 1080 as a true progressive signal. 
• Having a DVI-I connector the BayCats DVI input suits Digital and Analogue signals and needs to be told how to set the EDID (Extended Display Information Data) correctly to reflect the type of connection between a computer and the display.
• If using Digital then set for Digital, if using Analogue then set for Analogue.
• This setting is accessed by going to Main menu, then Advanced, then Miscellaneous.
• An indicator of this problem is that the BaCat displays the PC boot up screens then blanks out as Windows tries to load. EDID is what Windows Plug and Play uses.
• If the EDID information is not communicated correctly between PC and display then conditions can arise where the PC sends a resolution to the display that is larger than what the display thinks it's getting. When this happens typically the display will allow the PC's signal to "scroll" through the display.  If you notice that the whole image moves off screen when you move a mouse to one side or another then this is the case and you should investigate that 1) EDID is set correctly and 2) that the monitor/display resolution that windows indicates is set correctly. This is usually found under the Advanced button on the Display Properties window on the PC.

• There is no point in changing the refresh rate of a source PC in the Display > Settings tab > Advanced menu. The Clarity display has a fixed vertical refresh rate of 60 Hz. It will handle other refresh rates, but the native refresh rate is fixed. The BayCats internal electronics changes the incoming refresh rate to the display’s fixed refresh rate.

This setting is accessed by going to Main menu, then Advanced, then Miscellaneous. Page 34 of the BayCat manual explains EDID further. Please read it.

An indicator of this problem is that the BayCat displays the PC boot up screens OK then blanks out as Windows tries to load. EDID is what Windows Plug and Play uses.

Lamp life is the median life of a large sample of lamps.

Median means middle. It is not what most people think of which is average.

Suppose the specification for lamp life is 5000 hours. If you had a large group of these lamps, more than 100, and you turned them all on at the same time, after 5000 hours at least half of them would still be on.

Suppose 50 of these lamps had failed after only 1 hours of use. Then suppose the rest of the lamps failed after 5001 hours. The average life of these lamps would be 2501 hours.

But the median life specification is still valid, because at least half of them lasted 5000 hours. This is the way all lamp manufacturers specify lamp life— as the median, not the average.

Taking a different case, suppose the first 50 lamps failed at 1 hour and the rest of them lasted 10,000 hours. The specification is still valid, because at least half of the lamps were still working after 5000 hours.

You are unable tell from the lamp life specification how long any one lamp will live.

To have YUV connectors on a Bay Cat-X requires fitting the VIM (Video Input Module) HOWEVER the YUV input on the VIM only accepts signals as SDTV (480i and 576i, otherwise known as NTSC and PAL respectively).

To get HDTV at 1080i or 720p displayed on either a Bobcat-X or Bay Cat-X the signal must be connected to the DB-15 connector.

There is provision in both the Bobcat-X and Bay Cat-X for them to accept either RGBHV or YUV type signals through this DB-15 connector.

The Colourspace setting in the Source menu must be altered to reflect the correct signal type.

See page 14 of the Bobcat-X or Bay Cat-X manuals for more details

With the arrival of the "X" series of flat cats from Planar, a feature was added whereby a customer could "capture" a logo for use as the splash screen/curtain.

Unfortunately adding this feature made the "X" series incompatible with US military specifications for non-volatile storage. The military do not want any capability to retain information, of any sort, so the feature was quickly and quietly removed from later firmware revisions. Thus allowing Planar to once again sell to the military.

There is no benefit in "loading" old firmware supporting Logo Capture as the improvements in other areas of the firmware, like HDTV support and general signal timing and management, would be lost or not function correctly.

Logo Capture is not available on Planar products

Why Planars SP series of product does not incorporate the proven dual lamp system used on the Puma and Lion series of product.

 The SP series use a lamp switcher for the following main reasons

1. Lamp combiners are big and difficult to fit into the chassis.  
2. They tend to be heavy and add significant offset weight to our motorized optical engine mount.
3. Lamp combiners typically have fairly poor uniformity when run with only one lamp, which means that you must run both lamps all the time to get good uniformity.
4. The efficiency of the lamp combiners on DLP is not all that good compared to our AP/LCD stuff.  2 lamps typically only give about 1.4x the brightness improvement over a single lamp, so you end up throwing a lot of light away and doubling your thermal load on the system.

It takes about 30 seconds for the lamp switch over to happen once initiated and a total of approx. 45 seconds to have an image back up on the screen.

M57L is design for both landscape and portrait modes as long as they follow our operating temperature spec (0 ~ 30C). 

Make sure they rotate clockwise portrait mode because we only allow one direction only.
