Mounting

Unless you want to use a projector, you will have to think of a way to mount your display.
The display will have to be mounted horizontally, so you can place minis on top of it. In general, there are 3 approaches to achieve this:

Laying on a Table

The simplest option would be to simply lay the display on a table. You will probably have to remove the display's foot.
If the back of the display is flat, and the cables can be inserted from the side, this might just work out perfectly without doing anything else.
Otherwise, you could make use of the VESA attachment points (assuming your display has them), and attach a piece of wood to these attachment points to raise the back of the display clear off the table.

Display Enclosure

A display enclosure is a, generally wooden, enclosure into which a display is mounted.
The advantage of an enclosure is that it look prettier, and offers better protection.
Displays enclosures can be bought, or you could build your own. You can google terms like "RPG TV enclosure" or "RPG TV case" for shops, inspiration or build plans.

Display Table

The last, and according to many people, ultimate option, is a dedicated display table. This is a table with a built-in display.
These can offer better protection and look better than enclosures. Additionally, your setup is pretty much always ready to go. Many of these tables have built-in accessories, such as dice trays or dice towers, and many have a cover that allow the table to be used as a normal table. However, these tables are generally very expensive, or take a lot of work to build. You can google terms like "RPG TV table" for shops, inspiration or build plans.
