thank you for that
after trying everything i finally found out that the problem is the hdmi port on the ps4. one of the golden strips was bent to the back and was not touching the cable. i managed to pull it up using a knife and it all worked however im not risking taking the hdmi cable out incase it happens again. i guess the reason is i change the hdmi cable from ps4 to laptop alot since my laptop screen is broken which might of pushed one of the golden stips back. only solution is to buy another hdmi cable for the laptop.
Ah I know what you mean as my PS3 output plug is a bit loose as well( works fine though) because I kept taking it on and off switching between my consoles but if you're still in warranty on your PS4 they might be able to fix that for you at no cost.
My advice is that if your Tv is out of HDMI input slots then buy a HDMI switch and another HDMI cable so that you don't have to constantly remove and switch your cable around
