Dell 2417DG Flashing different colours

[Savo.]

Hello,

I turned on my monitor this morning, and the monitor was flashing different colors. It was flashing red, green, blue and white.

When I booted up my PC it had the color settings back to default. When I brought up the monitor menu it was in the top left corner, instead of the bottom right corner.

And then when you turn off the PC, the colors flash again. The monitor works fine, but when the PC is off it flashes different colors. And every time you boot up the PC the monitor color setting are reset.

I have tried different ways to fix it, from reading certain ways that are recommended. But I have had no luck.

If anyone knows a fix for it, it would be appreciated.

I bought it new from Overclockers.

I have had the monitor just over a year now, it was a year in November.

I rang up Dell and they have sent me out a replacement, which came this morning. When talking to the man on the phone from Dell he said to keep the stand and cables, and to send back the screen.

But the replacement monitor came with a stand. Should I send back the just the faulty screen, or send back the screen and the stand?
