computer monitor has little “waves”
August 4th, 2016
now i’ve tried to see what the problem is..i found out that only my small computer monitor can work without the flickering if i put it on a res of 1280×1024. but when i connect my other one (1600×900 max res) it has flickering, and i tried to change the refresh rate but the only option is 60hz. same with my 1920×1080 TV.
i tried updating the video drivers, still, + the video card is kinda new since my computer came back from repair not to long ago and the video card was replaced with another one of the same model (GTS 450) ..but im going nuts! cant figure what the problem is :S
thanks in advance!
I’m pretty sure it’s the low refresh rate that’s causing it. Usually video card can detect connected device cababilities and restrict certain resolution and refresh rate combo to protect the monitor.
Tried another cable?
VGA cables are not really that great these days, the TV’s and LCD monitors these days use digital connections.
So they’ve cheaped out on the video signal chips for analog (since no one uses them anymore). Analog signals were pretty prune to crosstalk and EMI. Back in the days, you can get away with cheaper VGA cables, these days it only applies to DVI, HDMI or DisplayPort. I’ve just made a change to DisplayPort from single-link DVI, its much more convenient as there is no more screws to tighten.
has this just started to happen ? what was it like b4 u changed the card ?
i tried updating the video drivers
with the ones from nVidia ?

Like i said, the only option for a refrseh rate is 60. ic cant change it.
yes i tried other vga cables. also when i connect a vga cable after putting a dvi adapter still the problem remains.
the problem started when the mobo, cpu and video card in my pc were changed after repair, but its kinda wierd that the problem may be in them since the parts are really new.
but like i said when i connect the hdmi cable from the pc to the tv everything is fine
and yes – the one from the nvidia website
1600x900 max res
CRT monitor ?
1920x1080 TV
LCD TV ?
and they both get the wavy/moire type effect ?

LCD’s are 60Hz in most cases but a CRT monitor can have a higher refresh rate
is there any “centering” or “size” option in your monitors OSD menu ?
You actually solved the problem, its the interface.
You can’t use adapters as your still outputting analog signals. If your monitor is CRT, you should actually replace it.
Using a proper DVI connection or HDMI will solve this.

1600×900 – nope, a regular little lcd montior
1920×1080 – yep, an lcd tv
they both get the wavy effect.
i tried playing with the screen options but still, nothing had solved it :S

i am using an hdmi cable to avoid the waves, but its still isnt supposed and never happend to me with the VGA..

As I said, VGA is very dated, the quality control is worse than ten years ago when somewhat most of us were still using CRT monitors.
Now its the cabling and the video card output signal conversion chip, both have gone down.
Signaling the time to move on with newer interfaces.
I wouldn’t use VGA these days, ever.
yeah but still…even if its too old for modern days, it isnt supposed to make this problem, no?
