Hi - I'm trying to link up our Pana PT-AE1000E projector to the Pana TH-37PX80BA tv via an HDMI cable however the length of cable required is approx 10 mtrs. The price of the recommended cables makes this length prohibitive but I am worried that cheaper cables may not be able to carry the signal. Any ideas or advice please?
Length of HDMI cable v quality of signal

All cables reduce the signal to some degree, and this can become a problem over long runs, as can interference getting in.
Make sure any cable you buy is guaranteed to deliver 1080p over the 10m run you need, and test it uncoiled before you install it
However, I'm not sure what you're trying to achieve connecting your projector to your TV - I think you're going to find that the HDMI sockets on the TV are all inputs, not outputs, and even if one is configured to output signal from the TV's internal tuner, I think it will struggle to drive cables this long.

Thanks for this. Purchasing the cable was my first step - I think next I need an amp and some surround sound speakers. I'll take your advice over getting some kind of guarantee.
Right - but again until you get a receiver and an HDMI splitter (or a receiver with two HDMI outputs) you'll need to do some cable-juggling to switch from BD to TV to BD to projector.
And unless you have an external TV source (Freesat, Virgin or Sky) I don't think you'll be able to get the off-air TV picture onto the projector.

According to QED's (I think) website, the issue with long lengths of HDMI is down to reflection of the signal by the join between the cable and the connector. In normal cables this isn't an issue because the degree of reflection is related to the frequency of the signal, and most electrical signals are relatively low frequencies (not much more than 20kHz for audio). HDMI though is extremely high frequencies (340MHz?) and the reflections become significant at distances of 10m or more, so they have to start fitting active connectors at each end. I believe this is what increases the cost.
