Default display change it's own?

I have a big problem a lenovo laptop(E535). The problem is that when I turn on the laptop, the display work durring the boot phase and when it arrive on the password screen the display turn off, then to make it work I have to use the win+P hotkey to change the video output on the integrated display. It looks like it change the default video output on "projector only". In the bios the video output is set on the internal display. I tried to uninstall and reinstall the gpu drivers but it didn't worked.
Any advice? Thanks

P.S. If I uninstall the gpu drivers and reboot the pc without them the display keep working.

Lenovo ideapad y700 or Dell Inspiron 15 Gaming 7000 Series?

Both of these computers are on sale due to the holidays but i don't know which one to get. Both seems to have similar specs but that's my opinion. So what do you guys think? (Getting a gaming desktop is not an option at this moment… I have considered buying and customizing one but I'm in a situation to only buy from those choices… I apologize if that sounded rude but I have had enough answers with that idea and i wish i could but only in the future for now…)

How Much to replace audio jack plug in?

I have a Lenovo Y410P Laptop and the problem with it is my audio jack plug in where i plug my headphones into on my laptop is messing up. Everytime i play music even if my headphones i plugged in, half the audio still comes through my laptop. I know it is not the headphones since i have tested them on other devices and never had the same problem until now. The audio jack plug-in is really loose and is messing up, does anyone know how much it would cost to replace the audio jack plug-in since i don't know what to do.
