Does it just do the red tide thing when you are gaming or has it done this randomly? My first guess would be that it isn't the monitor but to be safe you might want to check your monitor cable connections, shut down first and then make sure the cable connections are seated correctly. If this is something that only happens when you are gaming I would suspect that the problem is related to the onboard video. Many opt to use an after market video card in order to get better video results, especially for gaming. Your computer should have at least one PCIe slot, which is where the vid card would go on the motherboard. This is just a guess and it is not to say that it couldn't be the monitor but I lean more toward an onboard video issue. Again, the first thing, check the cable connections. Best of luck!!!
My monitor is an HP S2031. The computer is a Compac Presario CQ5814 PC, Processor is an AMD
Dual Core Processor E-350. Running Windows 7 Home
Premium 64 Bit. Bought in 2011.
Running Chrome Browser most of the time. Shockwave
crashes on me quite often but seems to "fix" itself. This
had happened shortly before the monitor turned red.
I had turned off the computer and when it was turned back
on the screen was red. I restarted it a couple of times and
it finally returned to normal.
Any idea why this happens?
