Have you seen these in action? I am skeptical of all "don't need curtains" claims for projectors unless they are based on actual experience, every shitty $100 pocket projector says you "don't need curtains" which is barely even technically true in most cases.

I was sceptical at first but then I saw some photos and YouTube videos of people using them. Have a look at this, it’s not an ultra short throw one but it is a 4k laser one. The guy is using it outside in broad daylight to watch Netflix: https://www.amazon.co.uk/Nebula-Polaris-Pro-Projector-Black-Gray/dp/B09BJM4BZQ/ref=mp_s_a_1_2_sspa?crid=TYBWXFHJ44XY&keywords=anker+nebula+4k&qid=1662652990&sprefix=anker+nebula+4k%2Caps%2C135&sr=8-2-spons&psc=1#review-media-gallery_1662653027545 https://www.amazon.co.uk/Nebula-Polaris-Pro-Projector-Black-...

  It claims 2400 lumens - I have a couple of flashlights in excess of 6000 and yeah, the light beam is visible in daylight but I can't see any way you'd project something with decent contrast even with that.

  You mean the promotional videos? You don't get to make black over a white surface in daylight.

    No I mean the user posted video and photo reviews on Amazon and also the odd YouTuber. And yes, it is not going to be as good as a TV outside in broad daylight. But they are almost definitely good enough to use inside with the curtains open. And if the light isn’t directly in your eyes like a monitor, do you even have to code in dark mode anymore?

  That says it has a brightness of 2400 ISO Lumens, which roughly translates to about 600 nits according to this site[1], (although my back of the napkin math of 3.426 nits to lumens would give a worse 408 nit rating, but I think this page probably did a better job, so we'll go with that). This seems pretty low compared to even OLED TVs, which are of course worse than LCD TVs. I may be comparing peak brightness to average brightness though, hard to get a clear idea here. But, if my understanding is correct, with a project you'll also miss out on true blacks, right? 1. https://cybershack.com.au/cybershack/nebula-cosmos-laser-4k-finally-a-mini-projector-that-sees-the-light-review https://cybershack.com.au/cybershack/nebula-cosmos-laser-4k-...
