From: Mike on 19 Sep 2006 16:54 Hi all, VERY weird problem I am having here. I bought a 25 ft. vga cable to run from my shuttle to my 19" widescreen flat panel. The native resolution for that puppy is 1440 x 900. It runs fine on the default VGA cable that came with the monitor, but when I hook up the longer cable it won't even let me select 1440 x 900, and just lists a bunch of unsupported resolutions. My thinking is the cable is having a problem rpoperly recognizing the monitor, but I didn't even know cables did this to be quite honest. Am I going to return this one and get another instead, or is there some way of forcing the cable to recognize the monitor? FYI I have tried looking for drivers for the flat panel, but Proview doesn't make any, and any I do find, don't seem to install... but the monitor works fine on the smaller cable with the default monitor setting anyways so I don't see how that could be the problem. Any help would be mucho appreciated :) Cheers Mike

How much did you pay for the cable? For a 25' cable to work, it needs to be very high quality with lots of screening for each conductor. you could try 2 of these:-- http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=1831 Mike.
From: DaveW on 19 Sep 2006 18:56 The practical fact of the matter is that the recommended LIMIT for VGA cable length is 10 feet (3 M). Beyond that the signal attenuation is too great to obtain a useable image. -- DaveW ---------------- "Mike" <mikekleiman(a)gmail.com> wrote in message news:1158699274.777985.281970(a)m73g2000cwd.googlegroups.com... > Hi all, > > VERY weird problem I am having here.

From: Johanna on 20 Sep 2006 11:00 Hi Mike! I used to have a Shuttle actually, that was connected to the monitor with a VERY long cable - 30 metres (98.5 feet according to converter. (I posted about this previously in this group and got some very helpful advice. ) The cable was very high quality from, a company called Lindy. The connectors were gold plated and the cable was insulated. I was using an nVida medium spec graphics card in the Shuttle (e.g. I was not using the native motherboard card). The monitor in in question is an Acer 20" widescreen. With this cable I DID get the SAME resolutions/frequences as with a normal length cable. Everything was the same except for one thing: The imagine was sort of 'floating' a bit - just shaking a tiny bit. This was down to reduction or disturbance to the signal. It was really no major problem - Not more irritating than viewing a CRT in 60Hz resolution. However I found it unbearable anyway.... and ordered a 15 metre cable from the same company! (I had miscalulated the length I needed, so 15 metres did the job. This is 49.2 feet. ) The whole thing was a terrible waste of money. I still have the 30m cable which cost me ?80..... Cannot in good conscience sell it. Somebody in this group told me I was pretty daft for buying it in the first place.. can't argue with that.. ;-) You may want to look into whether there are signal boosters available. . If you are certain that you need a cable this long, you should probably make sure that all the components are high-end, e.g. graphics card... (I imagine...?) but mainly the cable. I am not particularly good with this stuff, just sharing my experience... However I can verify that the 'max 3 metres' rule does not apply if you are using a high end cable. The 15 metre cable (49.2 feet) from Lindy works flawlessly with my Acer monitor and nVidia graphics card. Good luck with this Jo Michael Hawes wrote: > "Mike" <mikekleiman(a)gmail.com> wrote in message > news:1158699274.777985.281970(a)m73g2000cwd.googlegroups.com... > >>Hi all, >> >>VERY weird problem I am having here.
