Hi-Def: highly, and definitely, confusing Jun 17 2006
So I’ve been toying with this post in my head for a few days. I recently bought a Samsung HD Ready 32" LCD TV, and so a week or two ago I decided to get my Mac Mini hooked up to it, using Front Row as a super-duper media center. I soon realised that while the TV touts HDMI/DVI connectors, it really just means HDMI. I’m well aware that essentially, HDMI and DVI are the same signal with different connectors. Why we need two connectors I’m not sure, but certainly DVI-D (completely digital signal) and HDMI are one and the same and so a DVI output from a PC into an HDMI connector will result in a totally digital signal from start to finish.
Now, after my initial disappointment that there wasn’t in fact a DVI connector on the back of the TV, I stuck with VGA (it has a PC input too) until I researched cables and connectors further. I assumed therefore that running using VGA, that HD output from Mac Mini to TV wasn’t possible. I skipped over the fact that the TV picked up on the PC signal, with the Mac switching resolutions to the TV’s native 1366x768 (720p). It didn’t dawn on me that HD could still be possible, as I assumed it needed a digital, not analogue connection.
So onward and upwards… after laughing so hard I thought I was going to break my spleen at the idea of 60 (just over $100 for those across the pond) to buy a gold connector DVI->HDMI cable, I was thinking I’d just give up on the idea, til a trip to eBay came up trumps. 8 (around $14) for a gold connector 2m cable for running from a DVI source to an HDMI connector on a TV. However upon plugging this in and hooking it up to the Mac, it became apparent that the TV and Mac had decided to stop communicating, instead deciding to only offer me some default resolutions (1280x768, 720p, and 1924x1344 or something, equivalent to 1080i). I’ve read that the Intel Mac Mini’s now allow slightly non-default resolutions in order to cater for the native resolutions of TV’s, however I’m out of luck with my PPC Mini (I’ve read about various display tools to achieve the same thing, but am well aware that the wrong settings, especially when talking about refresh rates, can break monitors and TVs).
Long story short, the HD space is crowded with confusion. I’m still not 100% on my thesis that HD will work over VGA or DVI, because its simply based on resolution, so whatever is supported by the TV and output source,will determine if HD is a possibility. I’m still currently using the DVI->HDMI cable, running at 1280x768 (720p), however am not sure if the VGA might provide better quality. And of course, when my Sky HD installation eventually happens (now delayed a further 11 days because of a shortage of boxes), it’ll require the HDMI input, and so I’ll be out of luck unless I buy a switch.
I intended to keep this post shorter than I have, but that pretty much sums up my experience with the integration between HD capable computers and TVs - after all of this, I discovered while playing the test H.264 HD QuickTime videos available from Apple’s website that really my PPC Mac Mini isn’t powerful enough to play HD content anyway - sometimes it just about struggles through, often it chugs and stops and starts making the video, while incredibly detailed, totally unwatchable. I’m now thinking of either a newer Mac Mini, or perhaps even a Windows based media center, more on this later.
It should be said though that Front Row is awesome, and with the Mac also hooked up to my home theatre, I have a simple, elegant way to access and play all of my music collection, as well as the movies, TV shows etc I have stored. It looks truly beautiful on a 32" widescreen TV too.
