Hi AV forum

I'm looking for a Projectors with 0.66 inch texas instrument chip (1528px) & vert/hori lens shift.

I want the high quality native chip with with flexible lens shift.

Preferably low cost solution like the Optoma UHD60 & Acer M550, these models are great but just so inflexible for small rooms & special setups.

I was considering the Epson 4010 for its strong lens shift, but it's only 0.4inch chip (1080px) and need the sharpness on small fonts when I do programming on the projector. I only use it for movies 20% of the time. Rest is surfing and programming.


Resolution reference of difference chips (0.47”=1080p, 0.66”=1528p)

Are you sure you really want the 0.66" for text display?
It has a huge disadvantage vs the 1080p panel version.
Because 4k isn't exactly divisible by the native panel resolution you will have uneven pixel scaling, so if you feed it a 4k desktop with 100% scaled small text then font lines can become uneven.
Whereas the 1080p chip can be doubled simply to get to 4k pixels. But the 4k chip often doesn't have such good optics on it.

Definitely you should demo before buying if you will spend a long time looking at it (unless you have a good return policy to take advantage of).
 
Hi @jfinnie 16m25s this video shows the increased detail that will make text more round on curves. Are you sure a 0.47” will make more sharp text? It seems like the one big advantage of 0.66" is things like small text. Please clarify if there is some truth to what you state.

Unless I am missing something, the .66 one has higher native resolution, and so would be a sharper text display. You would just feed it the native resolution no?
 
It's a good theory :) Are any of you guys using a 0.66" at native panel resolution? Do they actually support native panel resolution on HDMI? Check the manuals... Note I don't have personal experience of these units, just going from the published data from manufacturer.
UHD60: https://www.optoma.co.uk/ContentStorage/Documents/d673c68e-ab0c-46e1-8e05-503ac694142a.pdf
M550: https://global-download.acer.com/GD...847.528909285.1570136822-214789099.1570136822

Neither of them list native panel resolution as supported input resolution. If this is true then for both 1080p or 4K pixels you have interference patterns for single pixel patterns because there isn't an integer factor between panel resolution and input resolution.
 
I assume they are using the highest available input resolution. If a projector company produce a projector that has its bottleneck at input resolution, please let me know. This does not make sense to me. Would be a waste.
