LF specific keyboard + mouse + bluetooth dongle combo (10$ to 30$)

Hi,

I've bought some times ago a great LG TV, which uses webOS (and not Android).

It's 120hz 4k and i'd like to play my PC games (far away from TV) using a broadcast system. I've been successfully using Moonlight atm.

The issue is, when i want to play keyboard and mouse games, if i wire in the TV a keyboard and a mouse, the TV will have a maximum amount of inputs registered at the same time.

For example, if i'm pressing shift + W to move and moving mouse while clicking left click, only 3 inputs will be read. This makes many games unplayable using M&KB.

I've been thinking trying a mouse + keyboard + dongle/station combo, where the dongle/station would "retranscript" all the infos as one. Might work, might not, i'd like to try.

And decent recommendation for such a setup in that regard ? I'd be playing on the couch and won't be playing any competitive games, i'm mostly seeking for comfort and durability at that price ...

Thanks in advance for any answer or idea.
