New LCD problem

I just bought a Gateway 700GR computer from Best Buy. I installed it using an older DELL CRT monitor and it seemed to work fine. After a few days I decided to purchase an LCD monitor (SynMaster 712N). After I installed it the computer did not see it at first. I turned computer off and back on and the monitor worked. Since then, if I turn computer off and restart with in 5 or 10 minutes the monitor comes on. If I leave the computer off overnight the monitor does not come on at first but does after a computer restart. So far this has been 100% consistent. Is it the monitor I should take back or a problem with the computer. It just occurred to me that the one thing I have not tried yet is to unplug the monitor from AC and plug back in when this problem is occurring. Any thoughts? Thanks - Larry

 

I have on older LCD monitor that doesn't recognize the scan rate that most machines use for the BIOS setup. This has created issues when I need to tinker with the BIOS on that machine, I have to drag a monitor over to it. I think I'd take it back, a new panel shouldn't have that kind of problems.
