its just really annoying for me..
how can I remove #3,4 ? seems like everytime i restart my computer another display would appear..
You do not say so but based on your screenshot, which shows a dropdown arrow to the right of the adapter name and a "1." before it, you have two adapters that have dual monitor connections. That is what you are seeing--not four monitors but rather four available (even if not used) monitor connections.
If you do not have dual adapters and "Device Manager" obviously thinks it sees four it is probably a driver problem.
If all is working as it should--ignore it.
If you are so badly bothered that you want it "fixed," here is what I would do:
Create a "System Restore" point and/or create a backup.
Starting in "Device Manager" uninstall all "Display Adapters" including their drivers if given the option. Shut down and physically remove the GTX-285(s) and install (temporarily) a different video card, enable the onboard, or whatever and reboot. Setup the temp card so that you can more easily install any of the available freeware driver cleaners/removers (one I have used in the past is Driver Sweeper). Run it and clean the unused hopefully unneeded drivers out of your system--do not go overboard--just concentrate on video drivers.
Repeat all the above only this time remove the temp video adapter and put the GTX-285(s) back in. Get it all setup as before and then rerun the driver cleaner/remover. Hopefully any "hiccups" will be gone.
FYI: the OS, that is "Device Manager," often sees things that are not being used and even are turned off/disabled. Mostly onboard devices that can be and/or are turned off/disabled in the BIOS/CMOS settings such as video/audio adapters, serial ports, parallel (printer) ports, etc. can still be "seen" by the OS, "Device Manager," and shown in some form, ie. as the wrong number of "monitors," as an "Unknown Device" and/or improperly installed device. If everything is working as it should and you are not having MANY (almost every one has one/few) driver related BSODs then you are better off to ignore the "hiccups."
