[Golf_Park]

Hey guys,

I came across an article talking about the release of the new Optoma EH412ST and it looks really impressive with a price tag of $899 so i thought i would share it here..

here are some specs:

- 4000 Lumens
- 1920x1080 (native) / max: UHD 4K 3840x2160
- 50,000:1
- short throw (0.5:1)


here is a link for full specs:

any thought?



cheers!

frodaddy00 Generally if there is a bad one in the bunch I get it, but sounds like I managed to get one of the good ones. I am 78" away from my screen and have an image size of 156" x 88" in 19:6, I set it to 4:3 and have an image of 118" x 88" which is just what the chart called for. Only thing I can think of is I got one of the first ones to come out, wonder if they changed something in production after they got started? Other thing I was thinking about is if you change you aspect ratio to 19:6 you could move the projector closer to the screen and fill the side to side though you would loss about 23" total top to bottom. With my setup it worked out for me as to I was able to move the imaged down cover the top of my screen and move my netting down more, that enabled me to get rid of the notch in my screen upper right, and to better protect the shelf I hung the screen from against ball impact, not sure it would work for you but I just thought it might be worth mentioning.

[frodaddy00]

Yeah I could write off one projector as being bad but the replacement has the same issue. 78" distance giving you 118x88 does sound spot on.. driving me crazy what is wrong with mine!

I will try 16:9 and see if I like it better and then maybe try moving the projector back and to the right some (to avoid my swing follow thru).

[BGCurtis2nd]

Don't have a clue why there would be a difference between the one I have and any others they made, and with the replacement having the same problem makes me wonder just what is going on. I have seen two different post by two different people claiming they have discontinued this model, but I still see advertisements for them saying new item coming soon Pre-Order, and that includes the site I got mine from so I don't have a clue as to what is going on.

[WisBowHunter]

I was wondering why you were in 4:3 when you screen should be able to handle 16:9. How did it turn out in 16:9?

[Uk101jkt]

I'm very confused by Optoma. As previously mentioned they cancelled my 4k550st order. In Asia apparently this EH412st is not available but they are offering me a GT1080HDR which looks exactly the same and has exactly the same specifications. I'm guessing it's an updated Darbee??
I doubt HDR affects TGC19 so probably no point getting this one and might just get the old Darbee. It doesn't seem like much has changed but again seems like Optoma change part numbers with only minor incremental changes or am I missing something.

[frodaddy00]

FWIW the HDR setting looked terrible on my projector.. washed out the picture a bunch so I turned it off.

[Deko212]

frodaddy00 just a thought - your HDMI cord may not support that resolution and be downgrading your output. Or a potential issue with your video card not supporting that resolution.

[frodaddy00]

I haven't spent much time looking into HDR but the cable supports 1080p and the vid card is an RTX 2060. YMMV but for me it looks better disabled. I didn't want to waste the extra $$$ buying a 25 foot 4K cable when I don't have a 4K projector.

[Celeras]

I must be missing something. I put this thing into the calculator for my 151 diagonal (8x10.5) screen... and it tells me to set it 6'9'' away. For 16:9 it's even closer than that.

How are you guys hitting from that close? I'd be smacking into my enclosure with this thing, and it'd be completely inside some of the deeper ones.

[frodaddy00]

My enclosure is only 5 feet deep.

[BGCurtis2nd]

Celeras Here is my setup, the recessed spotlight in the picture shown between the Uneekor and the Optoma EH412ST is directly over my tee, which is just over 10' from the screen. My Optoma is 6' 6" from the screen which gives me a 179" diagonal image at 16:9. Hate to say it, it is almost like taunting "Murphy" but so far no one has hit it.

[Celeras]

Gotcha. I get anxious just looking at that haha. I was taking it for granted that everyone puts it above the hitting zone I guess. At least yours is protected though.

I received a replacement projector and it has the same issue.. at 81" away at 4:3 aspect ratio it does not fill a 91"x121" screen. Apparently the throw ratio calculators are incorrect I tried a couple different ones.

In fact I have the projector about 95" away and it still doesn't fill in the entire screen.. so now I just have to live with wasted edges of my brand new impact screen.. about 10" total top/bottom and about 4" left/right. Oh well I will live.

It makes no sense why its not sized properly its just basic Physics II Optics...

What resolution signal are you feeding it? Are you in aspect mode native, 4:3 or 16:9 on projector itself?

[frodaddy00]

I run the desktop for projector image at 1600x1200 (the highest 4:3 aspect supported by the projector). I leave the projector aspect at Auto.. I tried switching around desktop resolution vs. projector aspect and it doesn't really change anything.

I've got it setup now to fill in the entire screen but it sits about 95-100" away instead of the expected 81". The downside is its too close to my overhead swing plane to be comfortable but I don't believe its in serious danger. My concern is when I have some friends over if they have steeper swings it may be in harm's way.

[wbond]

Is the projector mounted directly over your target line or is it offset to the side a little. If it's directly over the target line, no matter how steep the swing, it really shouldn't be able to be hit.

[frodaddy00]

I tried to get it directly overhead but this projector does not have the horizontal keystone..so its just a bit left of my target line (as a right handed golfer). I've tried to simulate very bad/steep swings and none of them feel like they get less than a foot away..but its just a mental thing knowing this $900 equipment is "within range" of an object moving 100+ mph

[BGCurtis2nd]

frodaddy00 I have mine set at 4096 X 2160 from the computer to my monitor and projector and also in the resolution on TGC 2019, I have QED set to it's highest setting but do not recall just what it is, but when I did the comparison below I don't recall changing anything other then the aspect on the projector. I do recall that I had to go in and change the setting in TGC 2019 because when I first brought it up it did not fill the screen.

[Uk101jkt]

I have now received the Optoma 1080HDR which has exactly the same specifications at this unit so i believe it is just renamed for the Asia market and so far im not impressed (although i dont have much to compare it to).

My ceiling height is very high at 12.5' and the throw distance of this unit is very short at 0.5. With a 200" diagonal screen the projector is positioned around 7 feet from the screen and requires a lot of keystroke to correct the image and this is resulting in a slightly blurry image on one side. Anyone have suggestions on how to improve this? I dont want to drop the projector height as its infront of the hitting position. I tried using the negative zoom function and going further back but that didnt help.

With a 200" diagonal screen and a 1080 projector is this the best i can get? Its fine with movies but when in normal computer mode reading the writing at around 10-12 feet from the screen is difficult; especially on the left hand side. Those of you with large screens and the darbee what did you do for your projector settings?

[wbond]

The writing on the perimeter is not as crisp as the writing in the center. I figured it was just inherent with projectors, but maybe not.

I am awaiting delivery of Optoma EH412ST.
I don't even have my golf station built yet, but I am very close. I also have high ceiling around 11 feet. I bought the OCM815W Low Profile Universal Ceiling Mount
with a 36" extension. This will have the projector at 8 feet height.
Based on the calculator on Optoma's web site, I'd need to be 80 inches from the screen. This should work out fine.

[JLo]

Hi, so the EH412ST looks like it is identical in specs to the Optoma HD29ST, so I suspect the latter is just a renamed version for the European market. It also looks very simmilar to the GT1080HDR so that might also be a renamed regional version? Anyway, I bought an HD29ST recently and have just run a comparison against the GT1080 which I had previously. It's on youtube - https://youtu.be/qWeVmYef634 . I don't use it for a golf sim but from the brightness think it would be very well suited and a significant upgrade over the GT1080 in terms of brightness.

[JKCapeCod]

Nice comparison, we have the GT 1080 and are considering upgrading. Possible to the https://www.optoma.com/us/product/gt1090hdr/

[Throwingdarts]

I'm deciding between the Optima GT1090HDR, EH412ST, and EH460ST. Each have a throw distance of 7'6" to the screen getting a diagonal image of 206". We are hitting from 10-11 ft away. Does anyone see any problem with the distance between the screen and projector taking into account we are hitting almost 4' in back of the projector? If so, any recommendations for another projector?

[steve51523]

i have the eh412st and have been very disappointed by the picture quality. it doesn't seem to be focused and seems closer to 780p than 1080p.

I just posted the same thing on another thread. Can’t get it to focus for the life of me. Very underwhelmed by the pictures quality and clarity. I’ve spent hours trying to dial it in with mediocre results.
