Question

Colours are not correct! Reds are pink, Blues are green ect.

Apr 16, 2017 8:10AM PDT

I have a vga cable from my monitor to a dvi-a convert which goes into my graphics card, however this morning I tried using a splitter (2 VGA females to dvi-a) for my two monitors, however when I plugged them in the display changed colour.

Now i just have my main monitor plugged in to how it was before when the colour was fine but its obviously isnt. I have tried changing the dvi converter, vga cable and even tried it on another monitor so it makes me think that is the graphics card? HOPE NOT! Sometimes the screen goes yellow when I move the cable which is weird aswell.

Ive only had this computer for 6 months, since October so I hope its not the graphics card.

I have tried various VGA cables, DVI-A converters, monitors and computers. When I try connecting my girlfriends PC the colour is fine and works properly but mine doesnt obviously.

Your help will be much appreciated!

VGA is analog.

So from my view it's not broken just not working. VGA being analog is subject to problems like this. Either use a color calibration tool (too many to list here) or go with a setup that works.

Links?

Ah okay, so how was this caused? Any ideas? also could you link me to a free color calibration tool please? Thank you!

Not Working

Hi, I found a colour calibration tool and it doesnt work, I think its something to do with something external but everything seems fine to me, when it obviously isnt. when i move the DVI converter around a little it makes the screen go yellow and all other colours, I manage to get it to stay in a position where theres no tint on my screen its just the colours are wrong like I stated above... reds are pink/purple, blues are greens etc.

You have to go with what works.

You have working setups and not working setups. Go with what works. VGA being analog will do this if split, loaded or many other reasons. It's an many decade old video spec so there is no lack of technical data here but let's cut to the end. Go with a working setup.

As to free color cal? You can google for that. I pay for ours.

VGA port f*****?
Apr 16, 2017 11:19AM PDT

Okay, well I just tried using HDMI form the graphics card to my TV (only diaply with HDMI I have) and it works completely fine, so im guessing its just a problem within my graphics card DVI port?

Is that something thats likely?

Thanks for the replies.

I have to write the port is fine.

VGA is analog so spliters, adapters and such can change the analog signal. HDMI on the other hand doesn't have that issue. Now if that TV port has some odd color adjustments I can't know that. This is an area there is only a lot of issues, not simple fixes other than to go with what works.

Yes I could in the shop pull up an oscilloscope and check signal levels but here we go another way.
