re : expensive cables vs cheap - this info is about HD TV on a PC, but may interest regular TV dudes.
========TL-DR============
single link cable = HD TV flicker
dual link cable = HD TV no flicker
========TL-DR============
I've been using various BlackGold HD TV tuners for a while. I've never been all that impressed with the BG's - losing tuners (quad thinks it's a 3 etc). SD is good, but HD tends to flicker. I put this down to me being an early adopter (ppl say later versions are better) >> I just watch SD TV.
Anyhow, several years on, I'd been reading about dual link vs single link DVI and thought I'd check to see what cable I was using (when I was watching TV). Turned out I was using a single link DVI cable (theory says it don't matter). I had a look in my spares box and found a dual link gold plated contact DVI cable (prob added to a prev Amazon order to make up the 'add-on' malarkey). I swapped out the old single link DVI cable with the dual link gold one, and fired up Windows Media Center. Guess what ? there was no flicker on HD TV.
So: new cable = flicker-free HD TV (SD not affected)
I've since read up on DVI + bandwidth and although single link DVI is theoretically fine for HD TV - my test shows a def improvement with dual link. Go figure . . .
I'm also sure the gold plate is irrelevant . . .
=======hardware=======
HD TV tuner BGT3620
MSI B85M-E45 mobo
Intel 4770K cpu
Intel Graphics
2 x 4GB Corsair Vengeance 1600MHz
27" DVI monitor 1920-1080
=======hardware=======
BTW - the above mobo supports 3 * HD displays (albeit VGA, DVI and HDMI - but still useful). Guess it's a Haswell thing.
