This is highly dependent on screen size and viewing distance.
On a computer screen or a phone screen? No, it's not really noticeable. Hell, on some phone screen sizes/distances, you might not even be able to tell 720p vs 1080p.
On a 120"+ projector screen? Yes, it is definitely noticeable.
I have a small home theater and picked up a refurbished 4K LED projector (Epson 3200) coming from an old 1080DLP (Viewsonic 8200) - massive difference!
As someone with a lowly 1080p projector and a 4k TV, I much prefer the 1080.
Viewsonic PX701HDH. I blow it up to 185" and I cannot see the pixels until I am uncomfortably close to the image.
The quality of the display/projector itself makes a huge difference. With a projector specifically - the bulb itself (and how much life left) is going to make a huge difference in picture quality.
But that could easily be due to the quality of the projector rather than the resolution. Everyone in here saying they notice differences is completely missing the point. You’d need to compare against the exact same panel type, manufacturer, model year, etc with the exact same manufacturing processes in order to come to this conclusion yourself.
I get what you are saying, however at 120", less than 20 feet away, you can literally see the individual pixels (especially at 1080). It absolutely does make a difference under the right circumstances, that is empirically true. You can test it yourself if you are skeptical but I'm telling you for a fact that on resolution alone there is a noticeable difference for anyone who has 20/20 vision on a big screen closer up.
I mean sure, but you can say the same about any resolution possible. At some microscopic distance on a 42k display you will be able to see the difference. Your scenario here is pretty much “if you use a display in a manner it wasn’t intended then you’ll be able to see the difference in resolution when you compare it to a display that is used in the manner intended”
I had a 6" 720p phone. Couldn't tell the resolution, but could definitely tell the longer battery life
Now play 1080p content on it to compare
agreed. I have a similar setup and our projectors are not even doing "true" 4k, it's pixel shifting. so the real thing would be even more noticeable.
Pixel shifting is for when it upscales, isn't it? If you have a 4k source, you'll get a 4k picture from what I read about this series.
That said, 1080p upscaled definitely still looks better compared to the old projector (though the newer one is also brighter, which also helps).
