Im seriously considering a Hanns-G monitor (see widescreen for sub £130 thread). This monitor is the cheapest available with a DVI connector. Now, a decent DVI cable is £20+, whereas i have a VGA cable already. so, i open the floor, is the quality of a DVI worth the £20+ additional cost?
 
A "decent" dvi cable?

All DVI cables have the same quality. As the signal is digital it either going to get there on not. No sense in spending £20 on a cable when the cheapest one will work just as well.
 
The biggest advantage from my point of view is that on digital mode there is no adjustment to be done on the display.

Graphics card talks to the monitor, monitor talks back - sets the optimum display size and refresh rate, fills it to the edge of the screen. Done.

If you buy a digial display, chances are that it will come with a functional cable to hook it up... so I wouldn't spend the £20 on a fancy one if you don't need it.

Is this like all the people who claim they need gold-plated connectors for their standard definition DVD player or amplifier? Sure if you're at the high-end it might be worth it, but for most users it's just a waste of money.
 
by decent I mean bought from a shop with some credability, not the £2 shipped from China ones available on ebay.
 
lol, ok then. but if i want the monitor next week i will have to get onto ebay soon. ebay sellers dont tend to offer next day delivery by courier like Oc do.

Whilst I agree with you about digital cables I'm going to have to disagree with you on the part I quoted. Every Saturday I connect up one or two dvd players and every now and then I try using the SCART cable that came in the box - trust me the difference between a really rubbish scart cable and a decent fully-wired gold SCART cable is really obvious - even on small televisions. When you start talking about amps - well it depends on what you call high-end - but certainly you've opened a can of worms.

oopse, i appologise

but it does seem like i have my answer, DVI is worth it. but should i got for a £4 one of ebay or a £18 one from a proper shop?

I bought a £1 DVI-HDMI cable to be used from my HTPC to my Sharp 42" 1080P screen. No ghosting, no shimmering pixels. Looks pretty good quality too. Also got a freebie HDMI-HDMI with Oppo, that has RF choke on it (pointless)

Buy a good DVI cable.

http://en.wikipedia.org/wiki/DVI

Digital
  • Minimum clock frequency: 21.76 MHz
  • Maximum clock frequency in single link mode: Capped at 165 MHz (3.7 Gbit/s)
  • Maximum clock frequency in dual link mode: Limited only by cable quality (more than 7.4 Gbit/s)
  • Pixels per clock cycle: 1 (single link) or 2 (dual link)
  • Bits per pixel: 24

but hey, maybe, just maybe wiki have got it wrong, quick email them and tell them! use your posts has proof! :p

EDIT* found this site before, which was a good read, here is a paragraph from the site, i believe this is mostly on long run cables and nothing to worry about with such a short run of cable, but it does prove that DVI has signal loss and the reason i know of this info, is because i wanted to know if it was worth the cost myself on a better cable.

Despite common belief, there is such thing as signal loss in digital pictures. When a DVI run is unstable, you may see artifacts and "stuck" pixels on your display; further degredation tends to flicker out or shake, and the ultimate sign of loss is a blank display. In-house tests on varying equipment have produced strong signals up to 9 and 10 meters long. Tests at 12 meters generally resulted in signal loss and an unusuable image on the display, and anything longer rendered no image at all.

I got both VGA and DVI in with my benq monitor. Nice of them :) . I would see what the quality is like on the screen before you potentially waste cash on a cable that will probably make no difference at all.

Fair enough - I'm used to using RCA and S-Video connections on DVD and stereos. You get a seperate co-axial cable for each one.

I just see people buying gold-plated everyting; cat5 cables, phone lines, RCA cables... it feels a bit like "Pimp My Stereo"

I think I may have the issue confused. Is this for a monitor or a TV?

Considering upto 1920x1200 is "single link" I would use the DVI cable which comes with the monitor (if one does), no need to spend anymore money on an expensive DVI cable.

There is no difference what so ever between a £1 cable and a £50 cable under normal circumstances. A 12 meter run is not normal.
But there is a difference, none the less, that is all am saying and am pointing out that a good cable is what i suggest.

Yes this is true any cable will do the job for the task in hand but there is a difference in quality and from my opinion if it takes a good cable to reach fasters speeds on DVI dual link, then thats the cable i want for slower speeds not being flossy, just a matter of assurance that this is the cable to have.

It's all personal choice, thats why the expensive cables are along side the cheap ones.

So Mr.Skeeter,

i suggest you buy a good DVI cable. :)
 
Digital is digital - it either works or doesn't.

And if you think buying a more expensive DVI cable is worth it because somehow the signal travels faster - then they've bought you...

You only need to look at some of the £70 HDMI/DVI cables made by Monster that a well known electronics store stock to see that people are buying into the more must be better mentality. As said, digital is digital, as long as you can handle the bandwidth and the signal gets to the other end then it doesn't matter how it gets there.

Analogue is a different kettle of fish but even then, not to the extent of many of the solutions.
 
I have used the cheap looking one that came with the monitor I use and it looks (on screen) just fine to me, if you are on VGA now and going to DVI you will notice quite a big difference there though :-) DVI is much better.

Not 100% true, but it does depend on how robust the signalling protocol is. SPDIF 'operates' over a proverbial piece of wet string, but is prone to jitter, and several other digital issues. Better cables can be usefull in the right place.

Regarding a computer screen, I've never had any trouble with the freeby ones that came with my Viewsonic, or Dell montitors, so I wouldnt buy a DVI cable. DVI's better than VGA because the signal remains digital longer.

Better shielding on a cable will help avoid interferance and bit errors being introduced by nearby devices (including the PC itself)... But as I said the cables supplied with most monitors are sufficient for the job.
