I have my laptop hooked up to my 4K tv via HDMI and for some reason it constantly loses the signal. I will will be doing something and the scrreen will all the sudden go black, it doesn't say signal loss or anything it just goes black. I then have to go to the Input Source menu change the input to something else then change it back to HDMI and I get my picture back. This has been happening ALOT, and I was wondering if someone can help. If you need more info I will be happy to provide it. My laptop is a HP ProBook 450 G3, I have the resolution in Windows 10 set to 3840 x 2160. The TV is a RCA model number RNSMU5536.
My display refresh rate is set to 30hz, I tried setting it to 60hz but wasn't able to even though the tv supports 60hz refresh rate.
