Windows 7: Second monitor flickers when there is a specific shade of blue

Second monitor flickers when there is a specific shade of blue

I have a strange problem with my second monitor. I use my laptop to do all my work, I have a second monitor (Gateway FHX2300) that connects to my laptop using a HDMI cable.

Whenever there is enough of a specific shade of blue displayed on the second monitor, part of or the entire second monitor would flicker, and look a bit static-y. The shade of blue that seems to make my second monitor go into fritz is the same dark blue used on the top of this page (that is why I am typing this on my primary monitor). It's also the same blue as the Windows 7 login screen so *sometimes* when I open my laptop, the screen would either look extremely distorted or be completely black with few seconds of the top or middle of bottom of the login screen showing but still looking distorted and static-y.

If my second monitor becomes all distorted I can Print Screen and paste it on Paint but the static and distortion won't show up if viewed on my primary monitor. I tried print screening this page with the dark blue above while the screen looked static-y. When viewed from my primary monitor it looks fine but whenever I drag Paint to my second monitor with the dark blue of this page in it, the flicker would come back. If I drag Paint back to my primary monitor, the static would stop again. I can literally do this back and fourth to repeat the static.

Is this a problem with my HDMI or my second monitor? Is there a way to fix this by myself?

have you tried to adjust the screen resolution or the refresh rate for the screen(s)? If not I would try doing that first and see if changing it does anything for ya. If not; you probably have some sorta issue where the graphics capabilities of the graphics chip just dont dont have what is needed to provide full color on the screen and monitor.

hey sorry for the late response this is a busy time for me.

Anyways, I've tried both your suggestions and the screen still fitz out when it sees the colour blue. I tried plugging my monitor to my computer using a VGA cable to see if I can reproduce the same problem and it still has the same problem. Doesn't that mean the problem isn't my laptop or the hdmi cable but the monitor itself?

Edit: I should add that the problem goes away the longer I use the second monitor. Like when I initially turn on my laptop, the second monitor would fitz out when it sees blue. But after some time has gone by, it can look at blue and be just fine. But the next day when I turn on the laptop and use the monitor, it would have problem with seeing blue again.

Ya, the monitor could be shot. The only way to know for sure is to hook up another, good monitor.
