Hey everyone,

So I have two screens that I have for my computer one which is a Samsung 28inch 4k monitor and a Samsung 55inch 4k tv which I use for my film making and photography.

Recently after purchasing the 4K tv every time I start up my computer or wake it up from sleep I am having to unplug the display port cable from my 4K monitor and then plug it back in for the computer to recognize it and I never had this problem when I had just the single 4k monitor. I then hear a connection sound the same one you get from plugging a usb in.

Another thing to note is that the tv is connected via HDMI and for some reason it defaults as the main screen for when I start the computer up to log in and I can't change it.

Is there something wrong with my monitor, I have already replaced the cable and the graphics card but this issue is still occurring?

My pc specs are
Motherboard: Asus Sabertooth X79
CPU: i7-4820K 4-Core 3.70GHz
RAM: 32gb ram
GPU: Gigabyte Nvidia GTX 980ti
PSU 750W Corsair
OS: Windows 10

Thanks for everyone's help in advance!

Kind Regards,
Daniel
