I might ring tomorrow and see if they would. I got the impression from their tech support that they don't care and "just to set it up to my preference". I think that the tech might come round and look at it for 5mins, decide it's not too bright for him, but would in fact be too bright for me who has to look at it for many hours a day.	kiki (762)
254804	2004-07-27 07:22:00	i wouldnt bother with getting someone to come and have a look - they would probably have to take it back to the workshop anyway. much easier to return it and get a different one or something.	agent_24 (4330)

Oh, just a few in electrical and electronic matters, one in business management, a couple of others in specialised technical areas, but the real biggie is 40 years on-job experience. That's the one that is current and really counts. > Those screens are not the answer kiki, in your > situation fitting one of them is like installing > giant water-cooled brakes so that you can keep > driving a car with jammed accelerator. >> How is that so? You wear sunglasses because you can't turn down the sun, but you shouldn't have to put dark glasses on your monitor. The vehicle analogy is a bit obscure I guess, but the idea is you would fix the stuck accelerator to stop the car from racing away at full speed, not try to use the brakes to keep it to the speed you want.

Billy didn't mention it, but a poster last year advised that, in his earlier years, Billy was a London University honours graduate physicist. I thought you would be interested to know that. >Why isn't it set up properly from the factory? X-( A shopkeeper told me that even if a monitor was set up correctly at the factory, it would probably require further adjustment once it was moved to a different location, due to the magnetic variances of the earth. Don't flame me on this one, someone else might be able to shed some more light (or in your case, less brightness :D ) on the subject. Cheers and good luck. :)	exLL (515)

You are absolutely correct exLL, in fact I mentioned it in my FAQ #3: >>Billy's tip: If you brought your screen in from overseas, it may be a Northern Hemisphere model and could need several degausses to get right, if it comes right at all. If in doubt, turn it upside down and degauss. If it looks ok upside down, that's the answer. Either take up Yoga or buy a new screen. This effect gets worse the further south you travel. I kid you not, would Billy lie? The earth's geomagnetic field is far from constant and if a monitor setup is marginal, sometimes they will perform well in one location but not another. The simple test is always to rotate it to an E-W position, degauss thoroughly and see if it improves. Of course Sod's Law states that the orientation that gives the best results will always be 90 degrees opposed to the only possible orentation in your workspace! The strength and angle of the earth's magnetic field varies between the equator and the poles, and naturally the polarity is reversed between north and south. There is also a further factor that causes the image to shift progressively sideways the further south (or north) you go. I can't quite remember the name of the effect but it is similar to solar wind. You can also observe this effect by turning a monitor upside-down. The image will move sideways by anything from a few mm to a cm depending on screen size. Many years ago a NZ company developed a range of colour TVs from an international design. Their first model had very effective horizontal and vertical shift circuits that could correct any error by shifting the whole scanning raster with a DC bias, but their second dispensed with these completely and used image shift only. It worked fine from Wellington north, but the further down the South Island you went the further the picture shifted until in Invercargill it was 2-3 cm clear of the edge of the screen. It was necessary to develop a four component add-on mod pack to get it back to centre. They also dispensed with vertical centering too, and another mod was required to get the bottom of the image down to where it belonged. TVs privately imported by immigrants from the UK or Europe also had these problems as they had a northern hemisphere tube. The problem has lessened a little with technological advances but it still exists. Only LCD screens are immune. You can also get electromagnetic shields that you put your monitor inside and that eliminates the effects of stray external AC fields, and minimises the effect of the earth's geomagnetic field. They are not cheap, but for big graphics monitors (21") they are sometimes the only way to overcome environmental influences or eliminate screen shake from external fields.

254809	2004-07-27 22:49:00	I have a 19" Viewsonic which I find very good and I use different computers on it and therefore different video cards. The current video card as I write this is an onboard VIA I think and it is quite "dull" compared to my TNT2 M64 video card which is quite bright and "white". Is there any way you could borrow another pc with a different type of video card and try it. You shouldn't have to buy a new video card to go along with your new monitor but maybe this is a factor. I have to say that is why I like to use a monitor for a couple of days before I commit to the purchase. Of course most companies won't do this so I end up trying a monitor from my friend who sells pc's and they are second hand (which this one was). I hope you get a satisfactory resolution.

254810	2004-07-28 01:49:00	I think we are well past any of those issues DD, the problem is much more fundamental than that and appears to be a basic factory (non-user)setup problem affecting the CRT operating conditions. Incidentally I operate two computers through one monitor via a kvm switch, one with an ancient 2MB S3 Trio 64V2-DX/FX video card, and the other an onboard Nvidia Riva TNT on an Intel S440BX MB and they produce absolutely identical display characteristics. Doesn't really prove anything I guess, but video cards shouldn't affect the basic display proprties unless the drivers are doing something odd or the settings have been tweaked.

254811	2004-07-28 04:37:00	Mmm Interesting. Another potential problem. I will have to send this back, and I was looking up courier prices. Courierpost for 25kg comes to about $100 island to island economy?! :O $20 for 5kg base ticket + 4 more to make up the 25kg? :O That is a load of money! How do Ascent and others do it? They seem to be able to ship it down here for only $16-$25...	kiki (762)

I would agree that the video card won't cause the issue covered in this thread, if it did then both Kiki's monitors would have the same problem. I do however get different results covering a large margin when running different comps through the 3 monitors I have set up as work stations, The older video cards definitely have a poorer image quality with many not able to produce colours worth spit, initially noticeable is white showing up as grubby, and the blues tend to be noticeable as well. Oh, and upgrade your video man, no need to torture your eyes with an S3 or a Riva TNT,it is 2004 after all :D	metla (154)
