Optoma 1090HDR Quality Issue

[Philippe Mph]

Hi guys !
I recently made my 2^nd golf simulator with a Uneekor Eye XO and I freaking love it honestly! What an awesome product ! (I also have a skytrak at home).
I made a bigger room at my office with a much bigger screen and I bought a Optoma 1090HDR and I don’t really like the result on my screen. I would like to know if the result is because of bad configuration of the resolution or anything with my computer setup or simply that projector is not really good for quality picture.

The problem is I cant focus the corners of the screen and they are blurry. The result is pretty good when I’m playing golf because I don’t have anything to look in the corners but when on the desktop it’s really messy. I’m pretty happy with the brightness/color.

Here are my specs:
Optoma 1090HDR
Gaming computer; 16G RAM / NVDIA 1660 GTX
My screen is a Carl’s Premium Enclosure 12Wx9H (diagonal of 171”)
The projector is mounted on the ceiling at 7,5’ to 8’ from the screen.

I have played with projector setting for many hours and I can’t find a way to fix that…
I have an ACER S1283hne at home with a smaller screen and the image is way more sharp but not as bright !
With a price of 2000$ for the optoma, my expectations were higher than this…
Is there something I am missing or it is normal the himage is no sharp with that projector ?
Heres a couple of pictures !

I will not be any help because I do not have my simulator set up - yet. I do have the Carl's enclosure/screen on the way and the same projector. Obviously, I have not set it up yet, but I am concerned about the problem you are having. According to projector central, the projector needs to be offset from the top of the screen by a good amount, but it also appears that you have it too far back, at least from their numbers. Without having enough offset due to the enclosure blocking it, would require the projector to be tilted and then using keystone to correct. The keystone will cause the corners to look out of focus (at least that is what I am told...). I hope to have my enclosure and projector up and going in a couple weeks and will let you know if I have the same issues.

I had the exact same issue and because of it, I returned the projector. Playing with the focus ring I could only get either the top half or bottom half fully in focus. In my testing I had the projector flat on the floor and no adjustments to corners or keystone. And still had the issue. I then got the BenQ TH671ST and the focus is crystal clear.

[kirkemg]

I am considering both units and with the gap in pricing this thread just doesnt make sense to me. The BenQ is half the cost. Do we really think it's the unit and not a settings issue?

[SkeetShooter]

But the BenQ is over 1000 lumens darker... so there must be something going on here.

[rkattech]

Yes, certainly a head scratcher and I made the decision just based on my personal experience with butting my head with settings for many days and struggling like OP here. The way I rationalized it to myself (perhaps incorrectly) is the Optoma 1080 was sub $1K and prices for the lumen difference. And then add to it cost of replacing lamps (as you wouldnt have to with the 1090 because its laser) and you get reasonably close to what the 1090 is priced at and of course some color/quality enhancements thrown in as well. So yes, the 1090 is brigher and if someone can figure out the settings issue to get it to focus perfectly, then you would be very happy with the result as I was hoping to be. But just based on my actual in home experience, I was not satisfied with the 1090 product. My second issue was the size of the offset which I knew about and thought I would be able to tilt and keystone around it (this was the first time I was installing a projector ever). But given initial focus issues, the tilted look of the projector on the ceiling made it look really awkward. Given the ease with which BenQ just worked, and perfectly in focus, and has a zoom ring (which I found easier to work with than the 1090 digital zoom), it was the better decision for me.

Thanks for you answers ! I'm seeing there's a couple of people having focus problem with 1090HDR projector...
Do you guy have any suggestions with a good projector (under 3k) ?

My screen is a Carl’s Premium Enclosure 12Wx9H (diagonal of 171”)
The projector is mounted on the ceiling at 7’ to 10’ from the screen.

After reading the spec sheet on https://www.projectorcentral.com/Opt...tor-Review.htm it looks like this thing can accept a 4K UHD input. It looks like you are using a 4:3 aspect ratio. Have you tried setting a custom resolution in your Nvidia control panel at 16:9 3840 x 2160 or even try trimming the resolution down with a custom resolution 4:3 2872x2160? I wonder if the projector likes 4K more than a 1080p input.

[Dax]

The projector accepts a 4K input, but it is not 4K.

[preludesam]

Dax I thought I was pretty clear it was input I was speaking about. Sorry if it read like I was expecting a 4K projection of picture. I’m just thinking it maybe likes the down sampling a little better than a 1080p input.

[Dax]

Understood cheers!

I have a GT1080HDR and similar focus issue but only on the lower right corner. Did you use the projector central calculator and make sure you mounted it at the correct vertical offset above the screen? It's definently a projector design flaw I think because I have no keystone on and have played with moving the unit around and still get the lower right out of focus. Like you said it doesn't affect the golf because a soft image on those spots makes no difference. For the price I didn't see anything that can beat it for lumens. Downside to the these is that the unit is very inflexible for mounting and needs to be perfect for positioning.

Are you able to back up your projector placement? The Benq TK850 would be a good option if you can - just make sure you won't have shadow issues. I just exchanged my 1090 for it. I noticed blurriness in the corners too, but the primary reason I switched away from the GT1090 was because it worked better for me to have my projector further away.

Is there a way to calculate for shadows with a standard throw projector? Thank you

Use graph paper or an online tool like Draw.io to sketch a side view, like the images we have at https://store.gunghogolf.com/BenQ-TH...NEW-p265749740 and https://store.gunghogolf.com/BenQ-TK...urb-p276344793

What GungHo said is best. I stood on a ladder and used a laser pointer from where my projector would be placed. I had my wife stand in the hitting spot and take some swings to make sure the laser wasn't interrupted.

That's a good method also! A third method: with someone standing in the hitting spot, lay down on the floor with your eyes near the bottom of the screen position about 4' to the left of center (for a righty), and look above the player's head to the proposed projector location, making sure you'll be able to see where the lens it without their head getting in the way.

I made my calculation and this will not work since i have 9ft screen height and the TK850 must be at 206 inches with a 171" diagonal screen...
There will be shadow because i am hitting at 8ft from screen !

I also purchased this projector for my first simulator setup. I’m not sure if I have unrealistic expectations but the image does not seem to focus. Middle text is slightly blurry and corner with windows clock much more so. Screen image is 10 feet wide x 7.5 feet high. TGC2019 image doesn’t seem crisp. I am standing pretty close to screen (7-8ft) so maybe even at 1080hd should I expect some pixelation/blur?

[jasonreg]

I have used this chart many times to justify new purchases ;-)



With a 10' x 7.5' screen your diagonal is bout 150" or thereabouts. Don't forget though that impact screens also degrade the picture to a greater or lesser amount depending on the quality of the screen. In any case, this is not a Home Theatre Screen.

Just a couple of thoughts to manage your expectations.

I need to show my wife this chart
