AI summary — not a quote
The BenQ TH575 is a highly recommended entry-level 1080p projector within the r/projectors community, frequently cited as the 'best bang for the buck' in the budget category. It is praised for its high brightness and low input lag, making it a strong contender for both movies and casual gaming. However, its low price point comes with significant physical placement limitations, as it lacks the optical adjustment features found in higher-end models.
Pros
- High brightness (3800 lumens) allows for use in rooms with some ambient light
- Low input lag (measured between 15-20ms) is excellent for casual gaming
- Noticeably better contrast and image sharpness compared to other budget competitors
- Exceptional value when purchased as a refurbished unit (often cited around $500-$560)
Cons
- Lacks horizontal shift and digital zoom, requiring precise 'straight on' physical placement
- Prone to the Rainbow Effect (RBE), a DLP-specific artifact that some viewers find distracting
- HDR performance can be inconsistent, with reports of flickering or limited streaming compatibility
- Limited to 1080p resolution in an increasingly 4K-oriented market

BenQ TH575 is the best by far in my opinion then the HD243x but it depends on how easy it is to replace the bulb.
Basically all Epson models are good for that use case. Same with the BenQ TH575.
I am looking to replace an old BenQ TH575, upgrading to true 4K and a solid-state light source to handle heavy daily usage
I was looking at the BenQ Th575 / Th575i but looks like I would have to move the ceiling mount to fit the screen correctly.
The BenQ TH575 is a solid 1080p projector. It's got a sharp image and good colors. But, it has a LOT going against it. Most notably is the use of a lamp... the BenQ really doesn't have the smart features that are native to the XGimi. The setup of the BenQ can be painful.

The JMGO N1S 4K is a well-regarded triple-laser projector praised for its versatility, portability, and integrated gimbal design that simplifies ceiling projection. Users generally find the image quality sharp and clean, even when projecting onto plain walls, though opinions are mixed regarding its performance in high ambient light. It is frequently highlighted as a strong value choice in the sub-$1000 category, particularly for its native Google TV support and built-in Netflix.
Pros
- Integrated gimbal design allows for easy 360-degree positioning and ceiling projection.
- Triple-laser light source delivers impressive sharpness and natural color detail.
- Built-in Google TV/Android TV 11 provides a smooth app experience with native Netflix support.
- Highly portable and includes a protective case for travel.
Cons
- Limited connectivity with reports of only a single HDMI port.
- Brightness may be insufficient for environments with significant ambient light.
- Susceptible to the 'rainbow effect' (RBE), especially noticeable on white subtitles.
- Some users report severe eye strain or headaches from the laser light source.

They did so well with their N1S 4K & co. Have the older version & very happy but kind of want the 1700 lumens upgrade
Parent context: I have the same projector. I think I'm sensitive to the rainbow effect too, whenever I scan my eyes on the screen quickly. Very noticeable on white subtitles, or anything very white and tiny of course. Reply: Even on white, I still notice it. It really doesnt bother me unless there are white subtitles. Gaming is a joy.
On my jmgo N1S 4K, the experience (110") is so much greater than my TV. I never use the TV for gaming nowadays.
The MALC (Microstructure Adaptive Laser Control) technology in the JMGO N1S 4K already significantly reduces the speckle effect... However, the choice of screen plays a crucial role in the visibility of this effect. I tested this projector on a Fresnel screen and my reference white Lambertian screen. The Fresnel screen, due to its structure and composition, tends to accentuate some of the speckle effect, making it more noticeable. On the other hand, on a white Lambertian screen, this effect is practically absent, delivering a more uniform and pleasant image.
The XGimi Elfin Flip 4K and the JMGO N1S 4K are solid choices, but not nearly as bright or as good for home theater/HDR viewing.
