Question about HP f2105 21" LCD Monitor
Just added 4 g's of memory and a new graphics video card to our computer....tested all of this at the store on their monitor. came home re-connneted all wires and plugs and .....low and behold the monitor goes from green light to sleep mode in seconds....cannot do anything with a blank screen....we tried re-plugging everything....pushing any buttons at all and nothing!!!!!!!!!!!!!!!!!! PLEASE...........HELP..................
Sounds like your monitor is not processing the resolution signal from the graphics card. Reboot the computer in "safe mode with networking", from there you can play around with the resolution, start low resolution and work your way up to test the monitor.
