LG tiny 4K smart projector HU710PW is capable of projecting images up to 300 inches in size.

I've checked it's price...but I should have never done that

it's 'only' £2,498.98...so it feels like my 4 years old LG Minibeam PF1500G will be just fine by me for another 20 years

 

Assuming the bulb doesn't burn out...

 

LED the source of the light in the PF1500G, but nothing works forever

 

Ah, yes, the inevitable march of technology! xD

I remember projector bulbs used to be one of the main costs of the damned things...
