I have a new Sceptre 55" LED TV 2160p 4K, unlike my older 50" LCD TV, it has no VGA port, so when I looked online it says in order to use a big screen TV as a computer monitor the easiest way is to get a VGA to HDMI adapter, so I bought a plain one first, without the little square converter on it, it didn't work, when I searched why on Google it said I need the VGA to HDMI with the converter built in, so that's what I ordered, but when I hooked the VGA side to my PC and the HDMI part to my TV, nothing happened again,it says "no connection" or something like that. Now I know the HDMI port works on my TV because I tested it, I tested all (4) HDMI ports and also tried all others as well, like, MEDIA,YMPR? RCA etc, none work with this adapter, I searched Google and cannot find any answers, my old Sceotre 50" TV had a VGA port, so I just used my Desk Top PC VGA into the TV VGA and wham, it worked, no problem, but the new Sceptre TV does not have a VGA port, and I tried (3) different types of HDMI adapters,VGA. USB etc and none worked. What am I missing or doing wrong? Any help would be greatly appreciated, Thank You Very Much.
