Hi, I am new to the forum but got very interested reading through the discussions and getting to know the Gefen products. I am trying to solve a rather low-tech problem and wonder if I ended up at the right place. My issue is the following: I recently bought a new beamer (Panasonic PT AX-100) and even though the picture is much brighter I have interference 'waves' going through the projected picture (either bottom up or top down) that I never hade before. I suspect it has to do with the long s-video cable (12m), that I had to use as I mounted it new on the ceiling. Questions:
- Will replacing the 12m S-Video line with an HDMI cable potentially solve the problem (less chance for interference since digital & better signal strength over this distance)?
- As my AV Amp does not have an HDMI interface (but Component), will I improve or deteriorate picture quality versus my current S-video set-up if I switch to Component out on the Amp, then convert to HDMI? (I understand that using Component versus S-Video should be an improvement, but the conversion to digital HDMI will probably destroy some of the improvement)
- Any signal amplyfying/repeater needed for HDMI at that length?
- Will Gefen's 'Component Audio to HDMI' adapter do this job well?
BTW: I am not planning on using any HD source yet, I am mainly watching (PAL) television sourced through the VCR and sometimes DVD, both wired via S-Video through the AV Amp
I would appreciate any insight - a snowy cold hello from Switzerland

Although your setup would work theoretically, we do not carry a conversion from HDMI to component. I think your best chance would be long component cables. If not that, we also have a Component extenders that run over cat5. If you use cat5 shielded cables that will protect you from any EMI that you are currently experiencing.

Thanks for your comments - however, I am confused: I thought I would need a conversion from Component to HDMI, not the other way around (to get from the component monitor out ports at my Amp to the HDMI input port of my beamer). Isn't this what your 'Component Audio to HDMI' adapter or your 'Home Theater Scaler' does (the latter is what I really want, but it has to help solve my initial problem with interferences).
I would appreciate further insight.

Oh, you are right. I think I got confused about your setup initially.
Then, yes, component from your amp to our component audio to HDMI conversion box or home theater scaler, then a long HDMI cable to your projector is the solution you need.
For 1080i/720p signals, an HDMI booster is not needed for 12m of HDMI cable. However, if you are using 1080p signals, a booster is needed for that length.
As a digital signal, HDMI is not subject to EMI like analog signals are. It should fix the effect you have been seeing with your s-video cables.

Thanks for the clarification - this is what I was hoping for. In the meantime I measured the length of my s-Video cable and it is actually 19m (60ft) long. Am I right to assume that I would definitely need a HDMI booster then? (I want to be ready for 1080p) Will the Gefen HDMI Super booster cable do the job? Is the booster cable just a cable or does it come with a separate box? How does it get powered?
Last question: Both your home theater scaler as well as the super booster cable are for pre-order only. When can you ship?
So the solution will be : AV Amp -> Short Component cable -> Gefen Home Theater Scaler -> Gefen HDMI Super Booster cable 75ft -> Beamer HDMI-input

One more question: What is the diameter of the HDMI Super-booster cable (in mm - just the cable, not the connector)?

Christopher,
I think you gave me measurements for the connector, not the Cable. (need to understand the cable diameter (exactly in mm, if possible) as I have to fit it into an existing cable channel).
Thanks

Hey ck
Sorry about that. The cable diameter is (.392mm) This is a more precise measurement of the head connector: Width (1.591in) Length (2.52in) Height (.829in including top hex screw) |

Christopher,
thanks for the measurements. However, I think there must be something wrong with your 0.392mm measurement of the cable. Did you mean 0.392in? (A regular HDMI cable is already 8-9mm, a regular S-Video cable is 6-7mm, so I doubt you were trying to quote mm). Can you please double-check and confirm?
