Bias lighting

I have Hue bulbs in old lamps sitting behind my front speakers, but not through a Play Sync Box which is what's needed if you want the lights to adjust to the on screen content. It's just for some ambient lighting which won't cast on the screen.

I personally like gaming and watching films in total darkness, but my partner prefers some light so we often have those lights on a low orange so we aren't in total darkness. There's a white wall and blind behind the TV and it works well from a lighting perspective.

If you already have hue bulbs, you could try just sticking them in some lamps and putting them behind your TV and see how you like it.

I’ve used USB powered LED strips, can buy by length and even trim if needed. Adhesive backed, you can just run then along the back of the TV and choose a low light level and colour. Not sophisticated, but cheap as chips.

I love bias lighting and got a bit hooked on it via a Philips TV a decade ago. It can definitely help your perception of blacks and colours.

I have 3 hue play bars behind mine, which is overkill as I only ever set them to shades of white manually. It is quite nice to have the colour temp option though. Technically you want neutral white for films and absolute accuracy, but warm whites are nicer for more casual viewing.

I did love the full ambilight experience when I had it but the lack of upgradability of the sync box has put me off. It's an expensive bottle neck for your hdmi signals.
