A:AnswerIt's compatible with VESA 300x300 wall mounts, the screws are M6. Here's a link to the Owner's Manual: http://gscs-b2c.lge.com/downloadFile?fileId=U58CXHYRTOakKE8QvbXUg
A:AnswerIt of course comes with a single stand. You can though not use the stand & mount it either to the wall or mount it to whatever is behind it (furniture, etc). That will require mounting hardware. You can also look for a third party stand that would again use the four mounting holes in back of TV. Google the TV model with the words stands or low profile stand. Hope this helps.
