Hey guys I'm new to the forum and I've just bought a 24 inch Samsung SyncMaster 2494SW today. I have it pluged into my laptop which has a 4500mhd and performance wise its doing great. After a hour of use, I started to notice very faint distortions that look like waves all across the screen. Could this be a manufacturing defect or is it become I'm using vga cables?
Brand new LCD monitor displays faint annoying waves?

That would be the case if you had an LCD TV, as I have seen that for myself. Hooked up a 32" LCD TV to a PC through VGA, and waves were noticeable (not glaringly, but annoyingly).
I am not sure if that would also happen to an LCD monitor, but it's probably the cheapest solution you can try if you have a different type of connection available, say DVI.

I have intergrated Intel 4500MHD and it has no problem rendering 1080p movies on my friends 40 inch LCD TV through HDMI. The monitor itself has a dvi connection but my laptop does not. Does anyone know whats going on cause i don't think the monitor itself is defected.
VGA is an analog signal, and as such is susceptible to electrical/magnetic interference.
The wave pattern you're seeing is most probably a result of that.
Not much you can do about it, except perhaps using a better shielded VGA cable. But chances are that the problem is in the laptop itself.
I understand you do have HDMI? Try using a HDMI-to-DVI cable then.

Test the monitor on other machines, and if possible using both VGA and DVI on different trials.
If the problem persists in all other configurations, then the monitor is faulty.
Most probable result you will find, however, is that it is just the VGA cables if the phenomenon you are describing is what I think you are describing.
I switched the vga cable with another one that literally has twice the diameter and the monitor seams to be doing a lot better. The waves occur less frequently and when they do, it's intensity is not as violent as before. So I'm guessing its probably best if i switch to hdmi to dvi cables?
Actually, I'm planning on building a computer soon and don't want to spend the extra money on the hdmi cables. I do have a spare DVI cable somewhere. Do you think if I used that on my new build then the waves would disappear completely or should i just suck it up and buy the hdmi cable just to make sure my monitor isn't faulty.
Yes, in my experience the switch to DVI fixed the waves. They're really an analog problem, and going DVI removes analog from being a factor.
Huh, I have basically the -exact- same setup and problem. I'm in the process of building a new PC and the monitor is here but not all the parts, and my laptop also only has a VGA out and I've noticed those waves also. Quite glad to know that in a week or two when everything else is up and running DVI should remedy that. Thanks

Check monoprice for pretty cheap cables. No sense spending lots of money. Opens up your options quite a bit when you can get them pretty cheap.
