Answer:

yes. you can use of late about any open-handed of monitor with anything kind of computer you want. basically plug it in.
yes you can

as long as you enjoy to right connections
Absolutely. Monitors are not computer specific. As long as it uses a VGA connection, you should be fine. You can also check if it and your PC own DVI connections, which gives a better picture. However, a DVI cable is around $60, so you're probably fine beside VGA. :)
Yes, you should be able to run the Dell Monitor lacking an issue. Just plug the baby contained by, and away you go.
As long as the monitor uses like connector and signal type as the computer and as long as you don't ask the monitor to run higher resolution or frequency that it can, any monitor will work on any computer.



Analog monitor will work on an analog card, digital monitor will work on digital card (they enjoy different connectors, so they won't cross-connect). Some monitors have both types of connector.



Also, if your monitor maxes out at 1280x1024 pixels (image size), don't try to drive it to 1600x1400... and it it maxes out at 75Hz (refresh rate) don;t try to drive it at 85Hz. It won;t work... and may injury the monitor.
As long as the connector match you can use any monitor. Now a days monitors are plug and play which funds they don't need any drivers and can be used beside any system.
Yes a monitor is a monitor. As long as it is somewhat new, near in former times 5 yrs or so.
