Good Evening Golf Sim Hive Mind,
I've narrowed my projector choices to just 3. All are Optoma. All have a 1920x1080 resolution. The only meaningful differences are the brightness. Here's a link to the comparison on Projector Central: Projector Comparison
The GT1080HDRx and the GT1090HDRx are essentially the same projector. the 1080 has 3800 lumens and the 1090 gets 400 more lumens, a total of 4200 lumens, for twice the price (isn't that nice).
The ZH406STx is $500 more and has all the same features as the 1090. I cant really discern any appreciable difference. I don't know what makes it $500 better. Does anyone know?
And here's where it get's interesting:
If I run the calculator on these projectors and look at the brightness calculations things stop making sense, so i've created at table!
First off, does anyone know what the 'x' in the model name means? can't find it anywhere!
The projector central calculator seems to think most projectors aren't as bright as the manufacturer says they, and that's fine. What I'm not really understanding is why one projector with 4200 lumens is brighter that another with 4200 lumens, when everything about then is nearly identical. We're talking about a 50% increase in brightness according to the calculator's estimate. The other weirdness is that the calculator gives differing qualitative assessments of the brightness. It says the ZH406, at 42 fL, is recommended for rooms with low ambient light, while the GT1090 at 28fL is is perfectly suitable for rooms with high ambient light. WHAT GIVES?!?! I might be willing to pay the extra money for a significant increase in brightness, but with this info I can't really be sure what I'm getting.
Is anyone using any of these projectors? Care to post a picture of your projected image? Or use one of the free apps to measure the ambient light in your room?
I want to buy the projector that is going to give me an adequately bright image when the room has high ambient light, like when I'm playing sim golf with friends. If the relatively inexpensive GT1080 give me that, then that's great. If I get a significantly brighter image with one of the 4200 lumen units I'd consider the extra cost, but we're talking about a roughly 10% increase in lumens for a 100% increase (or more) in cost. doesn't seem worth it and the numbers don't add up.
I patiently await you insights and recommendations!
