16:10 LU935ST or 16:9 BenQ TK710sti

[Terry26s]

Hello All,

Building a sim room and advice from you guys would be great and appreciated. I have read a few posts, but wanted to be specific to my space.

My wall size for the screen is 145 inch(378cm) x 97(246cm). I am looking to get a premium hitting net and viewing area as big as possible.

a 16:10 suits the space and gives more height for impact at a viewing area of around 138inch(350cm) x 86inch(215cm).

My main question revolves around the projector. I would also like to watch films and the idea of 4k is preference. Needs to be short throw.

Would i be better off with the TK710sti laser 4k 3200 lumens but have black bars top and bottom for movies? Can I assume I can change the aspect ratio with my PC to 3456x2160? For 16:10 for golf?

OR The LU935ST has more lumens at 5500 and vertical lens shift which is useful for me mounting it higher as I have a vaulted ceiling. But is only WUGXA(1920X1200).

last thing with the TK710sti I know projectors should be mounted flat as such but what if there was a little bit of angle like 10° , would it affect image quality or size?

Thanks for any help and opinions in advance.

Welcome to the forums! I think you will find if you do a bit of surfing through the forum that most will recommend brightness over resolution especially if you do not have perfect control of ambient lighting. Several reasons:

1. Impact screens have a much more 'imperfect' surface than regular AV screens, that is to say the image will not be as clear on the impact screen as the AV screen
2. You need 'some' light even if it is limited to the hitting spot. And then generally most prefer not to be in total darkness outside of the hitting area.
3. Reflection and ambient light really affects the picture quality from a washout point of view
4. It is usually a trade-off. You can get 'affordable' high lumens, you can get 'affordable' 4K, Getting both usually commands a significant premium but YMMV

I personally prefer the extra height of my 16x10 WUXGA projector as I find the extra height a more immersive experience, but either would be fine. For me it would come down to what is the primary reason for the projector. If golf, go 16x10, if movies 16x9. Also I would not mind the black bars for movies but for golf it would drive me nuts.

To your last question, though not ideal, depending on the adjustments avail on your projector you should be able to manage a 10 degree tilt. Again, depends on the adjustments avail in your projector. Good luck!

Thanks for your response jasonreg .

If I get the 16:10 projector would movies play fine like with a usb dongle? Or would it still have black bars? Or does it depend on the format of the film or device? Or would it scale to the native 16:10?

[Terry26s]

Also if I have a 16:10 screen but this projector is 16:9 will the throw distance be based on 16:9? To match the height or would it be 16:10?

For a 16:10 projector, given that almost all content is 16x9 (or 1.85) you are going to wind up with bars on the top and bottom but this is generally not that big of a deal for most. I do not believe that the video will auto scale to a 16x10 format, nor I think would you want to.

Also if I have a 16:10 screen but this projector is 16:9 will the throw distance be based on 16:9? To match the height or would it be 16:10

Throw distance will be based on projector and projector position. There are many threads dealing with custom resolutions to best match your screen dimensions as best you can. Just search this forum for "custom screen resolutions" or the like and you will find lots of info.

jasonreg This is what I wanted to be fair, to be able to play golf at 16:10 at highest resolution and movies 16:9 with black bar top and bottom. Based on this with the projection calculator do I need to base this off a 16:9 viewing area or 16:10? In terms of throw distance? Cheers.

[jasonreg]

I think you might be thinking about this the wrong way. First off, not sure you can go wrong with either projector and the reality is you are only losing about 9" of vertical between the two given a fixed width of 145". Second, it is all about the projector you choose.

For me though, as I have mentioned, I would choose the brighter projector which conveniently in the case also gives the biggest vertical image (which I also prefer). Then I would install the 935ST using projector central to guide me as follows:



Make sure that your measurements are from the lens and not from the mount (yes lessons learned the hard way) and I would ensure that the bottom of my 16x10 native image is at the bottom of the screen for Sim golf use. Then, when projecting 16x9 content you would get black bars notionally both above and below your image. Make sense?

I have also been speaking to Benq but struggling to get answers, happy for anyone to jump in, and also thanks Jason for your help so far.

On the basis i go with the high lumens 4K 16:9 LK936ST (LK954ST) (i know its not what was discussed prior but it is becoming the one i will go for). Based on a screen size of 138" x 86" (max i can get away with)The throw distance allows me at 16:10 to be between 122" - 134" , based on 16:9 allows me 120" - 132". So i am thinking i can position at 122.8" and just alter the zoom lens rather then having to adjust the mount everytime.

Problem i have is the projection calculator at that distance for 16:9 makes the the width 378 which will run over the sides of the screen. Is there a way to still have the 4K image but it just be a little smaller width with black bars above and below?

Also with the Golf, BenQ mentioned it has a selectable 16:10 aspect ratio but would be better with graphics card at custom resolution. can i assume it would be 3456 x 2160 as per below?

I am trying to work out how/where i can leave the projector in one position and have the 16:10 screen full when playing golf at the highest resolution hopefully 3456x2160 as mentioned and then if watching a movie now and again not having to move the mount and just having the image fill the width with black bars top and bottom in 4K.

If anyone strongly believe the LU935ST16:10 Projector, will give me a better resolution, in Golf and watching movies rather than making adjustments/customs res to the 4K one do let me know please, happy to listen.

You can set a custom resolution to get the best tradeoff for your screen size. It is not difficult and the process has been discussed here many times (search "Custom Resolution" or "Custom Screen Size"). You may lose pixels off the sides of the screen but your pixel density (i.e. pixels per sq. inch) will be the same as full 4K resolution.

The 936ST is a great projector but spendy. If it is within your grasp then fantastic. Many do not find 'much' of a difference over WUXGA/1080P given the screen issues we discussed above but it is one of the best our there right now (price aside). Whether 'much' is worth the cost can only be answered by you.

jasonreg if i am not moving the projector and i want to fill the 16:10 screen for golf but still watching movies on said screen, am i inputting 16:9 or 16:10 as the aspect ratio, in terms of calculating the throw distance.

[jasonreg]

If you are just concerned about filling width, than it does not matter - each resolution has the same width. If you want to want to fill the screen completely, I would use 16x10 and position the projector at a place where the height fills screen top to bottom. Then adjust a custom resolution to "crop" the width.

See post #5 in this thread.

jasonreg - Appreciate your help and time to reply.
