Is there a single chord that could be purchased either online, or preferably somewhere like BestBuy, that could let my Macbook Pro display onto an HDTV, so I could watch movies on it that I have downloaded, without buying an Apple TV?
I'd also consider doing it in one chord and an adapter if it meant it could be purchased as BestBuy (eg Mini DVI to someother type, some other type to HDMI, or component, or composite, or whatever)
I'm not an expert on the whole world of this stuff, so try to stay with me 😉
you are going to need to buy the apple display adapter for this machine, which is a mini display port to dvi and connect it via dvi cable to your hdtv in order to get video in High Definition!
you can only buy this adapter from apple right now either at this link;
You need the Apple mini-DisplayPort to DVI adapter (assuming you have a Late 2008 MBP - you're posting in that forum), then a DVI-to-HDMI cable. If you have an older MBP, those have a DVI port, so you just need the DVI-to-HDMI cable.
That carries only video - you'll need a separate cable for the audio (mini-stereo-to-RCA, assuming your TV has analog audio inputs - if it has a digital in, you'll need a mini-toslink-to-toslink cable).
