Projectors are becoming increasingly popular among gamers looking for a more immersive experience. A good quality model will set you back several hundreds pounds, or you can easily spend over a thousand if you are looking for the best image quality.
Modern projectors are now capable of producing 4K images in bright stunning accurate colours, even when positioned just a short distance from your wall or screen. They are great fun when you have friends round and what to indulge in some multi player gaming with the sounds cranked up and a few drinks.
And when you are done gaming, they are fantastic for a home cinema experience too.
Good quality low latency full HD projectors that are suitable for gaming will cost more than your aveage monitor but if you want that extra size then check out, for example, the Optima.
