W3J VGA output = CRAP?!?

So I bought a Samsung 940BW 19" WXGA+ LCD (1440x900 DVI+VGA) to use with my new desktop. I'm still waiting on some parts, so I decided to hook it up to my W3J for kicks.

The results are AWFUL. There is constant and varying strength "waves" on the screen, like what you'd see in a bad television signal. I'm not sure what the technical term is but they are horizontal and "roll" or flicker up and down the screen. The effect seems to worsen under activity, so my natural reaction is to blame the W3J. I have never had anything remotely like this kind of problem with Samsung monitors before and I'm hoping it's not the monitor (although since I plan on using the DVI connector for my desktop, it might not matter)

Has anyone else experienced issues with the VGA output on their W3J?

 

my VGA is fine on my dell 24 incher. Also has great picture on my CRT. Have you tried using the DVI cable with the DVI to VGA converter attached?

 

The only converters I have handy are DVI to VGA, not the other way around. I may try hooking up my old 17" 4:3 tonight and see if I get any different results.

 

Try a different cable if you haven't already.

 

Yeah I'm going to try a few diff things tonight. As I said it isn't really important since I plan on using this monitor with my desktop via DVI, but I feel sorry for anyone planning to use an LCD with their W3J if this is infact a W3J issue.

I will report back with my findings this evening.

 

Yeah, I'd check your cable and your output settings. your complaint of "waves" has nothing to do with your particular notebook or is it particular to vga over dvi..... So, before feeling sorry for anyone trying to do the same thing, check over everything you're using first. The difference between vga and dvi isn't even going to be apparent on anything less than a 22" widescreen and even then only to someone who really know what they're looking for....

What's the refresh rate of the screen? If anything, that seems like it's more the problem than anything else.

 

I'd be checking with another cable, and then on another monitor. VGA is prone to interference with cheap cabling.

 

Well cables and such didn't make any difference, but when I run on battery, the problem disappears. When I plug it in, bang. Right back in your face.

Anyone have any idea why that might be?

 

the adapter might not be shielded, causing some kind of interference
you can try pluggin the adaptor into a different socket than your external screen
i hope that helps

 

also note that your moniter's optimal resolution is 1440x900@60Hz and maxes out at 1440x900@75Hz.

A 30-minute browse on google doesn't show anyone else with your problem and this model, so its probably not the moniter itself (unless its a unique rare case that no one has shared with the world).

I can only say what's been said before about testing the cables/changing the potential imput device into the 940BW.

The most optimal thing to do would be to test the LCD with the same cable and a different cable with a different output. If the problem occurs with one cable, you'll know its cable. If its both cables, just get the LCD exchanged under warranty. If its neither, then its possible the problem is at the W3J-end, whether itd be simple software setting, or a very mysterious hardware problem.

Cheers

 

Are you using a grounded wall socket?

 

Ok, well at least you can see there's a difference and something that's causing it.... I've never seen this before, so I'd assume the power brick is fine and either you're ungrounded or somehow or maybe you have an unshielded vga cable and it's sitting very close to the power wire...... ? It's got to be one of those two.

 

I am using a grounded wall socket with a six-way grounded piggyback box. The VGA cable and the power brick cable do both run through a hole in the back of my desk, so I suppose that could be the problem. I'll try separating them.

 

That could be a problem, let us know.
