SyncBlaster Cables


SyncBlaster Cables give you the power to easily connect RGB scart equipment directly to Plasma, LCD screens and projectors. Most screens struggle to work from the paltry 0.3v sync provided from an RGB scart. Enter the SyncBlaster. This fiendishly clever cable incorporates a fully functional sync separator and amplifier, providing the TTL level sync required for correct operation. Avoiding the need for yet another black box Keene have managed to cram all of the essential electronics inside the actual scart plug body. Not only that, it can draw its power directly from the scart socket (pin 8) so for most applications there’s no power supply to worry about either! So useful its almost scary.

SyncBlaster F.A.Q

How do I know if my display will work with the SyncBlaster?

Conventional video sources (eg digi-boxes, DVD players etc) will supply RGB video with a horizontal frequency of 15.625KHz. Computers supply RGB signals with a horizontal frequency of 31.250KHz. Most Plasma displays (and a few LCD panels) are able to accept the lower 15.625KHz signal on their 15 pin VGA connector and so will work fine with a SyncBlaster cable. A few displays however will only work with the higher 31.250KHz signal and in these circumstances we recommend connecting either to the RGBHV (BNC or phono) connectors, or converting the signal to component video. You can find the supported frequency for your screen listed in the technical details section of your manual and we have complied a brief compatibility list as follows;

PANASONIC – All models are OK

FUJITSU – all models OK

NEC – mostly OK, but converting RGB to component is a safer bet

SONY – all models OK

LG – No, we recommend using RGB to component

DAEWOO – all models OK

PIONEER – All models except 403MDE

HITACHI – 42PMA400, 42CMP4202 & CMP5000WXF all OK earlier models we recommend using RGB to component

PHILIPS - we recommend using RGB to component


We are still compiling our compatibility list and would advise that you check your owners handbook to see if 15.625KHz horizontal scan frequency is supported.

PC monitors (tube type)

ALL of these are designed for 31.250KHz and cannot be used with the SyncBlaster cable. You could however use a line doubler such as the PV200

Can the SyncBlaster cable be used with region1 (NTSC) discs)?


Picture size – why is there a border around my picture when I use the 15pin input?

The effect you are noticing is not a distortion but is caused by the way plasma screens and similar displays handle the different inputs. The cable does not change the shape or size of the picture. In fact the RGB signals are passed through unaltered.

Traditionally a TV picture is displayed "over scanned" that is with the edges of the picture completely filling and slightly overlapping the display. You can shift the picture slightly to the left or right before a border starts to appear. RGB signals from a computer or similar are traditionally displayed "under scanned" with a small border around the picture such that you can see the edges of the picture.

This is all done in the display device and plasma screens usually treat the RGB inputs as data inputs and "under scan" the image. The slight right shift is due to the timings from the Sky box, other set top boxes vary in this respect. In fact if you feed a number of different PCs to a plasma you will probably find that the picture position and size is slightly different for each one.

The way around the problem is to use the set up on the plasma to position the picture correctly and adjust the size to suit yourself. For most displays these adjustments can be stored individually for each input source.
