Setup issues on my conference room

[tazz85]

Hi, I'm working in one hotel, today we have one conference. We project on 2 screens - TVs which are plasma 50 inch Samsung - I'll tell you the model later, but I know that it's native resolution is 1365x768 - this says the official manual. Presentors today brought one BenQ projector. They're connected to HDMI splitter 1x4 - ATEN VS184. With my laptop which is HP 2000 with AMD E1-1500 with Radeon 7310 - everything is working fine at th highest resolution. We tried with Mac AirBook with mini displayport and connected it with DP->HDMI adapter. It didn't detect neither the projector, neither the TVs even with direct cable connection to either one of them. I don't know can be this issue with the cables, beacuse these are maybe cheapest ones, or beacuse they're 10m or both? SHould I buy gold-plated Sony? Thank you.

At 10m a cheap cable could be the problem but don't buy a better one until you try it with a short 1-2m cable. If that works then don't worry about gold plating, the gauge of the wire and the shielding is more important. There are also HDMI amplifiers like this:

that could be used with the existing cable.
If the short cable doesn't work then the DP to HDMI adapter could be at fault.
