Due to my eyesight getting a little worse, 3 days ago I decided to buy a
new 27 inch monitor to replace my LG IPS monitor which was still working
great.

After much browsing and checking makes and models on the internet and
checking loca suppliers I decided on the Asus MX279-H which was
available at Staples for $299.95.

So went to their brick and mortar store to have a good look at a demo
model,I would not buy a monitor without physically seeing it in
operation.

It looked beautiful so I bought it and took it home and installed it.
I used it for a while but was not satisfied with the colour so I spent a
couple days on and off trying to tweak the colour settings, but it still
looked terrible, the reds were pinkish magenta and the greens were sorta
lime green, blues were overpowering, it looked 10 times worse than my 9
year old LG.

Finally went googling to see if I could find others with this kind of
problem, in reading dozens of articles I still hadn't found anything
solid but did read where one article suggested a new cable.
Well I had it hooked up with a DVI to HDMI cable that came in the box.
So as a last resort before taking it back as defective I grabbed an HDMI
to HDMI cable from my blue-ray/TV setup and plugged it in HDMI to HDMI.
Well you could imagine my elation as it came up picture and colour
perfect.

Now here is the question, the DVI to HDMI cable was hooked up to my
video card DVI out to one of the monitor HDMI inputs.

the new cable was HDMI out of video card to HDMI in of monitor.
The DVI out of the video card is proven good.

Is this DVI to HDMI cable able to be used as a HDMI to DVI cable or are
the different cables? Or is it truly a defective cable?

Thanks for your thoughts and input.

Sounds like it's not a cable issue, but your video card is sending
different color information over DVI and HDMI. There are different
ways to deal with this depnding on your video card. My wife's laptop
produces terrible color output over HDMI to the television, extremely
oversaturated unless you mess with the settings.

Thanks to both Paul and Lifewoutmilk for two extremely informative
articles,I enjoyed reading them and learning a whole lot more about
computer video.
I switched cables this AM and still get same results, My Video card is
an Asus EA5850 full CU so is about 7 years old, I suspect you may be
right on the card sending out different video on the DVI or HDMI ports.
Anyway I am now connected with a new 3 foot HDMI to HDMI cable and
everything is great, perfect color and contrast, so I will leave
everything alone before I break it.

Thanks, Rene


Final follow up to the DVI to HDMI cable.
Picked up a new Bidirectional DVI to HDMI cable and plugged it in DVI
video card to HDMI monitor, Same crappy results, So it is not a bad cable.
Retried my old LG236 monitor, Same video DVI out to monitor DVI in(it
has no HDMI),And perfect results.
So it has to be some type of glitch with that monitor and video card.
End of story, leaving the new monitor and video card hooked up HDMI to
HDMI and all ends well.
