Nvidia Display driver Services Missing
Hi. I recently upgraded bougth an ASUS GTX 560 to use in my M.2 Beast. When I connect it to HDMI the screen remains with no signal. The HDMI cable is fine, the monitor and the GPU too because I asked to be tested before buying.
However, I noticed I can't use Nvidia Control Pannel (when I click nothing happens) and I think this is related to the service called "Nvidia display driver service". As far as I know (I don't know a lot to be honest) that service is incluided with the driver's .exe from Nvidia website, but in my case that service is missing. Does anybody know how to get that service or even make that GPU works?
Update: I downloaded a very old driver and now Nvidia Control Panel works, however now two things happen:
1) I can't turn on the laptop while HDMI is connected to monitor. If I do that the laptop won't turn on correctly and will ask me to reset. The will turn on badly and will ask to do the same in an infinite loop.
2) If I unplug HDMI the laptop turns on correctly, but when I reconnect HDMI nothing happens and the laptop doesn't recognize the second display, so if I use Nvidia Control Panel it will now works but will say "you don't have a display attached to a Nvidia GPU".
Update 2: after doing little research I am 95% sure this is happening because of the Nvidia Display Driver service, but I don't know how to fix this.
Update 3: Found the official driver from ASUS and installed it. Now if I turn on the laptop with EGPU attached, and also mini HDMI attached to 560 screen goes black and it freezes (or that's the conclusion I got based on fans sound). If I turn on with EGPU but mini HDMI not attached it turns on normally, but if I plug the mini HDMI it will start lagging a lot and creating two not visible displays. The ASUS' driver was Nvidia's 306.23 WHQL, while last avaliable driver for GTX 560 is 391.35 WHQL.
@oreste_colatruglio_mendoza, the control panel only works when a display is connected to the GPU. So you’ll have to resolve your display issue first. Also, please add your configuration to your signature.

@mac_editor I explained myself the worst possible. GTX 560 is attached to monitor by micro HDMI - HDMI, cable, monitor and GPU works fine all of them, so it must be a software problem. About Nvidia control panel, it is not like when you don't have a monitor that says "you are not using a display attached to an Nvidia GPU" or something similar. Right now when I click on Nvidia Control Panel, it does nothing, like crashing before start.
