Is it actually possible to do this?

Has anyone successfully tried this in malaysia?

Reason I'm asking is I rather not bother buying a new flatscreen TV just for a PS4 as my current CRT TV works fine and I plan on playing all PS4 games via remote play on my ps vita anyway so 1080p/720p HD graphics are not a concern for me.

I just need a screen for the ps4 to set up remote play and then I won't be gaming on the TV
