Any suggestions as to why I'm seeing double vision with my monitor? It started last week and will not go away. Could it be because my V3/2000 is getting too hot? Could that cause the screen to appear in double vision? It is still readable, but looks as if there is a shadow with each letter causing the "double vision" effect! Really frustrating.

Thanks

Is it there when you switch it on or does it take a while to come in effect?

Check the cabling and try wiggeligt the connectors a bit, it might be a glitch there (happens for me sometimes using my BNC's, don't know if it's the cable or connector though).

On TV's "ghost" picture is caused by poor reception, I think (but don't know) it's the same for monitors.

Hope it helps.

Then I'd check cabling and connectors, making sure everything is plugged in firmly.

If you have the option you can allways try with exchanging part, that is very offten what you do when trying to track down an error.

So if you have a old gfx card tru sticking that in and see if it goes away, try changing the cable and if those two doesn'ät work, well then there's only the monitor left I'm affraid.

Nolan,

I will try taking out my video card to see if that clears it up. If not, then I'm pretty sure it is the monitor!

Thanks again for the info!

What exactly do you mean by 'double vision'? These things can be hard to put into words, but please try - with a concise description, we may be able to offer more help.

Smeghead,

It is indeed hard to explain.

It is like everything has a shadow effect, thus making it appear like "double vision". Everything has an outlining "ghost image" around it. Don't know how else to explain it. It is really weird and totally frustrating! Any ideas?

Thanks,
Snowman

Snowman: How old is you monitor? It could be a solder in the connector (or indeed deeper in the dungeons of electronics) that's starting to give in if it couple of years.

Have you tried (have the possability) to swap any parts so far? My best bet would be something in the monitor or a connector/cable.

Just for the sake of it, have you tried de-gaussing?

Hope it helps.

Nolan,

My monitor is only about 5 months old and yes I have tried de-gaussing, but still no cure. I still have not tried taking out the V3 card to see if it's the culprit. Possibly tonight, I will try taking out the card. However,this is my second monitor from Gateway as my first one had a similar problem. They shipped me another one(#3)last week, but when I hooked it up I noticed some icons from the previous owner burned into the display, which let me know that they are not sending me NEW monitor replacements. I have since called them back and let them know that I realized that they were sending me used monitors. They apologized and are shipping me a NEW "tested" monitor this week. I was a little upset to say the least, but let it go because they have provided good customer service outside of this monitor fiasco! Anyway, I hope this will fix the problem, but it seems rather odd to keep having problems with my monitors. This is why I was wondering if it is my V3 card that is causing the problem.

Thanks for your input!
Snowman

Snowman,

You arn't using an extension cable on your monitor are you. The problem you described existed on my system when I tried to use a monitor cable extension cable. Removing the extension cable fixed the problem. I hear that this is a common side-effect of monitor extension cables.

Hmmm...what about colour convergence? Are the opposite edges of the displayed desktop different colours, for example the left border red and the right blue or green? Some monitors have controls for this colout convergence.

However, it sounds like a damaged monitor if you've had several the same way - I don't blame you for checking your video card out, though!

I guess I'll never buy a Gateway badged monitor, then...

I actually had the same problem when i got my refurbished Sony 400PS.
I was so pissed, cause i thought they shipped me a defective monitor.
The problem was actually with the DSub ocnnector in the back of the monitor. For some reason I have to bend the cable around a bit, to put it in tension, otherwise i get that ghosting effect you are talking about.

Every once in a while, the ghosting will com e back, and I have to go back and wiggle the cable connector behind the monitor a bit, and even squeeze it in there somewhere to tension it.

I tried two vidoe cables, and had the same problem with both, so I assume it is the connector on the monitor, not the cables.

The problem you describe is typically a form of a not correctly terminated signal line. High frequecy signals (high frequent, so short waves, compared to the length of wire they have to run through that is..). such a signal needs to be terminated at the same impedance as it is send, and the same as the typical impedance of the wire (cable) itself. All of course very interresting, but wat it means is: the only 'long wire' in such a system is your cable between the vidcard and monitor: so the problem has to be at the beginning, at the end, or inside the cable itself (this fits perfectly with the described problems of the connector of hacikura. What I would do is:
- try fiddling with the cable (near the connectors) while all is running, and look if the shadows increase/decrease.
- try another cable (borrow from friend/work/etc)
- if it doesn't help: try another monitor, but please use the same settings for this monitor: if you use for example a lower refreshrate, the frequency of the signals in the cable will be lower and the problem might 'disappear'!
- try another videocard...

good luck

Nolan,hacikura,Treets

Right on!!!! You guys were right! I jiggled the cables and rebooted and it is all cleared up! Well, I'm still going to keep the new monitor they are sending because I shouldn't have to jiggle cables to get a good display. Anyway, thanks guys! Awesome.

Well, I give up! The Double vision is back! So now I will wait for my new monitor and send this one back. I think this monitor is in dire need of some work. Thanks for the input guys!

"Nahnah-na-na-nahnah.. Get jiggy with it!"

Heh heh.. Sorry, couldn't resist.

Had the same problem myself a while back with a Gateway Crystalscan 17".. I got so fed up with it I switched to my present Panasonic PF70 TrueFlat and used the 5BNC signal input for good measure. I'm never going back! =)

Armchair Aviator,

"Nahnah-na-na-nahnah.. Get jiggy with it!"


I'm friggin LOL!!!!
Guess what, I have the exact Gateway Crystalscan 17" you mention! The "new" monitor they are shipping me is # 4. Can you believe it? Very frustrating, to say the least. Thanks for the very eye-opening input as I suspected these monitors had serious issues!

Snowman - if this 4th one is crap too, then I'd tell them to f*ck off and send a proper monitor next time. Raise hell at the highest levels within Gateway if you have to - this thing cost you money, so you're entitled to quality kit.

Well well well......Guess what?
I just recieved monitor #4 and it was DOA! The blasted thing would not even start up! Absolutely mind boggling. I spoke with a supervisor this time around and he said they are shipping me an upgraded monitor this time. Wow, I hope this is it.
At this point I don't even know how to feel, it's like a bad dream (friggin ground hog's day, Bill Murray style)

Hey Snowman,

Any way you can get Gateway to refund you just for the monitor so you can go and buy a better brand?

The FD Trinitrons out there right now are amazing.. And the 19" Mitsubishi DiamondPlus 91 with the FD Trinitron tube is a beaut at only $500. =)

I'll give that a try if monitor #5 gives me any problems! Suppossedly the monitor they are sending is a "considerable upgrade" acccording to the techs' supervisor. Well, we shall see, but this is definately the last straw before I will demand some kind of refund or "real" monitor such as the ones you mention.
