I'm having trouble with my BD player syncing the HDMI with my video.


I didn't know there was any such thing as a signal booster for HDMI, this is good to know. A quick check on amazon showed prices all over the map ($20 - $250) and reviews seem to be poor.

Does anyone know of a booster that has a decent reputation?

Are you sure the booster will help ? It is only useful when the cable is over 10M or more.


How long is yours ?

40' from the AVR to the projector. I might be able to get away with a shorter run, I haven't installed/hung the projector yet, so the cable is going across the floor. I wanted to get something long enough for the installer when he comes out. Its the highest quality one from monoprice in that length.


4034 HDMI Tin-Plated Copper CL2 Rated (for In-Wall Installation) Cable (22AWG) - 40ft (Gold Plated Connectors)


I see there are "High Speed" cables, but they only go to 25'. What I probably need is 28' if pulled tight. I didn't realize I needed to go as short as possible.


I'm not sure a booster will help - that's the purpose of this thread. Boosters on amazon don't seem to get good reviews - but I'm sure I'm not the only one on here with a 40' HDMI cable.

So, what do people do when they have a 25'+ run to the projector and have HDMI signal quality issues?

I got a 10M run of Blue Jeans 'Belden' cable(their heavier gauge one) n no problem at all. Maybe you should give it a try n they should have the same return policy as Monoprice.


I would avoid using a booster at all cost since it will induce some form of noises on the picture.

There is a lot of misinformation with HDMI. First the interface was never designed for the cable lengths we are using, it was designed for a max cable length of 5 meters (16.5 feet) with passive cables. If you have a system work with longer cables than consider yourself lucky but don't be surprised in the future if it doesn't when we get sources that start using the full bandwidth of HDMI. 1080P uses a little less than half of the HDMI bandwidth.


There are boosters and equalizers as well as other types of products for long runs. A LOT of it will be a crap shoot on whether it works or not. There can be many problems with HDMI and some of these only solve one of them. If it is the one that is causing your problem you are in luck. If not back to the drawing board.


We have found a few products that work very well. One is what is called a signal restorer and it solves most HDMI problems. Ethereal and Spectrum Electronic Solutions make them. They are not as cheap as the bargain ones but they WORK!


Other solutions for long runs are Baluns with either dual runs of Cat6 wiring or fibre optics. I prefer the fibre optics but it is pricey. For runs less than 100' I'd use the signal restorer. The quality of cables do make a difference with HDMI. Expensive doesn't mean better either but cheap is sometimes just that. I recommend checking www.dplratings.org for companies that pass their testing.


BTW, there has not been one passive cable longer than 6 meters (19.8 feet) that has passed their testing at full HDMI bandwidth. So you might get lucky with 1080P and a longer cable now but expect to add some type active circuitry to correct the signal in the future.

Thanks Bob. I found the signal restorer , and at $229 will put that idea in my pocket for a plan B.


Digging around a bit more, there is a powered repeater @ monoprice that has promising reviews, and at $58 is a little more wallet friendly.


Looking at my setup, I should be able to get away with a 30' cable as opposed to 40'. I got the 40' to be kind to my installation guy. Now that I know the idea is to go as short as possible, I'll remeasure and see if I can even do 25' with some extra planning. I'd like to be able to do 1.3a Cat2 throughout if I can - longest run of cat2 I can find is 25'.
