Reliability of HDMI connection

Posted by: PatG on 07 March 2006

This question relates to peoples experience of HDMI connections.

I have connected my DVD5 to a SIM2 20H projector using different HDMI cables.

Using one 10m HDMI cable, the image is fine but the picture drops out for approx 5 minutes at fairly regular intervale (every 20-30 minutes). Obviously this is an unsustainable situation.

Using a shorter HDMI cable from a different manufacturer, there is no break in image buy I notice some occasional colour flickering (very subtle on the whites and creams)

Anyone any experience of this?

Thanks & regards P

Are you using an adaptor, or a DVI-HDMI cable?

Hi.
I have the same setup as you and use a 15m wireworld ultraviolet cable and the only time i get a drop out is if i turn the dvd5 on before the sim2 ,which is a bit strange.
I also have a Arcam dv79 with a Pioneer plasma and the slightest movement on the hdmi cable at the Arcam end and it will drop out very quickly.

Cheers
Trevor

No picture drop out for HDMI cable of 2 m (my set up).

Even if your display has HDMI connection, you must keep in mind the feeder is the DVD5' DVI output. DVI specs forbid a cable longer than 5m (IIRC) so what you are experiencing is ''normal''.
A few companies are now offering boosters or special cables for longer runs. I know Runco has a signal enhancer called ''Live-Link'' it is garanted for 25m. They should now have licenced it to cables manufacturers.

Yep, sounds like a booster is needed. Our 32 metre HDMI cable has no "1"'s or "0"s dripping out unless a booster is used.

Thanks for replies.

I am using a DVI to HDMI cable.

Where are these boosters sold?

try googling "dvi booster" or "HDMI booster"

can be pricey depending on quality

Check the spec's first. I don't want to be blamed for the purchase of a incompatable product...
