Question TV and monitor giving "no signal" when i connect them at the same time via HDMI

Oct 19, 2020
I tried connecting my tv and my monitor to the pc at the same time i bought another hdmi cable and one splitter for it. After I connect them both at the same time both of them are giving me "no signal" error after they show picture for a few seconds on pc boot-up. I tried connecting only tv to my pc and it works perfectly fine, i tried connecting monitor alone too,same result. I tried switching their places on switcher and nothing happens and also i tried connecting both of them (not at the same time ) via switcher and everything worked perfectly well. I tried updating my graphic drivers but that doesnt help either.

PC specs:
Intel Pentium g4560 3.5ghz
nVidia GeForce GTX 1050 2gb
8gb ram
240gb ssd
1tb hdd
I'm using Fox smart tv,4k resolution and benq 21.5'' inch monitor.
Any help would be appriciated.
Sorry if i placed this post in wrong postforum
