Hi guys,
I hope that you can advise.
I want to connect my iMac to my TV. The TV has a lot of input choices but I am not sure which way to go.
On the back of the TV I have these sockets
DVI input PC input RS-232C AV1 AV2 AV3 ANT In AV4 (RCA) Conponent S-Video
The iMac has Mini DVI
On the Telly AV1 AV2 AV3 are all SCART sockets. AV4 is the red, white, yellow phono connector.
The iMac sits some 7 metres from the television.
How do I connect the two so I can screen share?
Thanks in advance
Cat

Do you sound from the iMac to be available from the TV, or just images?
Do you know what sort of DVI input socket the TV has? I am correct in assuming that by "PC input" you mean a 3 row, 15 pin VGA socket?

Since your telly has a DVI input it most likely is a HDTV so to get the most from your iMac i recommend a visit to the apple store to pick up a Mini-DVI to DVI adaptor and a really long DVI cable to hook them up as this will get you the best picture and best of all will run at the TV's Native HD resolution as opposed to a 640x480 resolution which you would get from the scart/AV/S-Video/Antenna Connections DVI -------------------------- Mini-DVI to DVI Adaptor---------------------------------Mini-DVI EDIT- The RS-232c is usually used as a "Service Port" for diagnostic use and firmware upgrades and will most likely not accept a video signal through it

I am correct in assuming that by "PC input" you mean a 3 row, 15 pin VGA socket? I don't know what a VGA socket looks like. In the manual it is just called a PC socket. It does have three rows I think and is sort of wider at the top than it is at the bottom.

Have I got that wrong or do I use a booster of some kind?

If you want to achieve image on TV at a budget price you could go with: a miniDVI to VGA adaptor (£15 in Apple Store) and a long VGA monitor cable (about £10 for 10 metre length).
------------------------------------------------------ As Doc already said, DVI should provide better image quality, however it will probably cost more. My understanding of DVI specifications are that they state that the output strength from devices should be powerful enough to use with 5 metres of cable. The devices at either end of the cable and the quality of the cable can have an impact upon the quality of image which you end up with on the screen.
If the image isn't perfect then you could use a DVI signal booster (anything from £50 to £150 roughly)
a miniDVI to DVI adaptor costs £15 in the Apple Store. a 10 metre DVI cable is £25 (from same local supplier as the £10 VGA cable).
--------------------------------------
Generally speaking, VGA or DVI cables over 5 metres in length are more difficult to get hold of from brand name high street stores.
Unless you can pick the cable up from your friendly independent local computer shop, many of the places which sell them online have a flat rate p+p cost which is quite high for only one item (but far more reasonable of you buy quite a bit from them).
