Hi All I want some info regarding dvi cables , i have just brought a TFT Monitor and there is no cable , what type do i need ? are there better makes etc ? The monitor is a ViewSonic VA2226W 22" TFT Monitor 1680x1050 300cd/m2 1000:1 5ms 16:9 DVI-D/VGA Black/Silver :confused:
 
This is what I use, it's a digital signal so a £5 cable will work as well as a £50 one.

Cat say as of rules and you have no contact info (and its BS above about any cable does as its digital, we had this convo last week here), BUT have you ever read a MAP*IN (your car) HINT HINT. ;)

You want a decent cable not cheap and not rip of either.

Better shielding/thicker cable if good quality wire and Ferrite's is all good.

P.S that cable above is Possibly DVI-A and Definitely not Dual Link.

Have you got a link to that convo and any testing done? As I have seen many differ with that opinion... In fact, the only ones who seem to concur are people selling the cables... Just interested to see what level of testing was done to back up the claim of it be a BS theory.

Especially as I have seen a £5 HDMI cable vs the £150 HDMI cable test with absolutely NO difference whatsoever.

I'm intrigued to see what level of signal degradation was reported during the testing and how it manifested itself.
 
good thing about digital cables is either it works or it doesn't.

Just make sure the cable you buy matches the metal type on the monitor and graphics. Its really stupid to buy a gold plated cable when your connectors are just copper. different metals = chemistry, and it will affect the connection over time.
 
Some peeps are dumb and buy into this "anything does for digital" lark.

Thin Cable/Badly shielded cable, lack of Ferrite's can all cause lower signal due to resistance and or interference, esp on longer runs

A £5 cable is prob crap and a £150 cable is deff a rip of.

As I told someone last week, I will stick to my modest costing cable and he can stick to his £4 cable.

Again that above cable in post #5 looks the wrong type.

Yeah , i,m just wondering where do you stop with all this kind of thing ? you could end up getting a bargin monitor for say £130 22" and then if ya wanted to be picky end up paying another £50 upwards for a super duper DVI lead only to hardly notice the difference unless your clark Kent ha! ;) so maybe say £10-20 is a stop off point ?

Yeah i agree with this , so is it a male to male DVI-D cable that you use for a TFT monitor ? or does this vary ?

Really? The DVI spec says you shouldn't have a cable more than 5 metres, and I'm running the cable I posted on a 5 metre run with absolutely no issues, the picture is perfect! Yes it's shielded, in fact I have yet to see an unshielded cable no matter how cheap they are. I paid £4.88 for mine.

Now, the more expensive cable may be stronger, and look nicer, but so say that it will give a better picture is complete rubbish. If the cable (no matter how cheap) did not work then they would not be allowed to sell them, which includes any resistance, inductance or capacitance that is actually high enough to cause problems... Simple as that.

I'm not sure if it's dual link - I use a 19" monitor at 1280 x 1024. It's definitely not DVI-A tho, as they have 4 pins around the long flat pin.

Totally agree with this !;) your sooooo right ,they don,t sell things that arn,t tested ,i know that coz i worked in an electronics firm for 19 years ! and your right all cables sold are sheilded today :) i thought most DVI cables were DVI-D ones and male to male ? might be wrong on this so someone will correct me ;)
 
i would never spend more than a fiver on a cable, no matter how good it is. Im simply not than anal about having the best picture possible.
I would bet money that the difference in picture quality between a £5 cable and a £50 cable would hardly be noticable, if noticable at all....

here here ! a man that thinks along my lines , after all are we to enjoy the p.c or sit and watch for faults every second lol ;)

The cable I posted is Dual link DVD-D (look at pin layout) ;)

Listen to reason and buy a decent cable that's Thick/Shielded and ideally has Ferrite's (£10-25 Depending on length) or listen to TOSH above, choice is yours m8. :)

this and only this. bottom line. to say anything different shows a complete lack of understanding of the subject, and to rubbish the first hand knowledge and experiance of others is so typically him. ignore him.

of course there are - they are the type of cables that will fall to pieces in weeks. nobody would recommend them. however, it will work or it wont. there's no inbetween, ferrites dont give you a better image. you wont get better colours or a sharper image by using thicker cable.... THAT is the single biggest (and most over used) misconception about digital signals over a cable. if a short run of dvi needs ferrites as you suggest, then how do we get away with running 10m lengths of HDMI cable without them?

the answer is obvious....it makes no difference :)

edit: also be aware you dont need dual link dvi unles you're runnign 1920x1200 at over 60hz or any resolution higher than that - QXGA (2048 × 1536) for example. you can achieve higher resolutions at oddball refresh rates like 17hz but in reality ive not see them used anywhere, or know of a use for them:)

I know all that :), Ferrite's are there to help with any interference (you can still get a picture with lines or such on it), I use a cable that's £20 (prob less now).

I still do not listen to some of the BS I read here TBH.
