I have a new TV and I’m trying to hang it on an old mount that I’m not familiar with. It is an Omni mount, but I don’t know what model. A TV is similar size was on it before. Is it OK to just use the mounts pictured attached to the TV and hang it directly on the wall and replace the horizontal bar? There is some other hardware here that I don’t know if it is relevant or not. I think the other thinner brackets that lack hooks pictured are for another tv…
