Auto-Keystone Correction

THE PROJECTOR THAT ALMOST INSTALLS ITSELF

BenQ's auto-adjust corner-fit feature is the install-friction killer most sim buyers don't realize they need. Mount the projector, press one button, and the unit auto-corrects the image to fit your screen geometry. No tedious manual keystone tuning, no climbing a ladder six times to nudge corners by eye. This is the single most time-consuming step in a typical projector install, and BenQ engineered it down to a single button press.

Commercial-Grade Lens Shift

MOUNT IT WHERE THE ROOM ALLOWS

Horizontal and vertical lens shift gives you total control over where the projector mounts vs where the image lands. Sloped ceilings, off-center mounts, complex retrofits, the LK936ST adapts to the room instead of forcing the room to adapt to it. This is the install-flexibility tier most consumer projectors don't offer at any price.

5,100 Lumens Of Laser Brightness

CRUSHES AMBIENT LIGHT AT OVERSIZED SCREEN SIZES

5,100 ANSI lumens is the brightness tier where you can drive a 150-inch sim screen with ambient light spilling in. Commercial-grade simulator installs, large entertainment rooms, and dealer-show floors run this projector for a reason. At a typical 120-inch sim screen size in a controlled room, the headroom is excessive in the best way.

True 4K UHD With Lens Shift

FLAGSHIP IMAGE QUALITY FOR ELITE INSTALLS

True 4K UHD resolution paired with full lens shift and 20,000-hour laser engine. This is the BenQ flagship for commercial sim installs, high-end residential builds, and any setup where image quality and install flexibility matter more than price tier. The projector you spec when nothing else fits the brief.

Easier Install Than You Think

MOUNT, PLUG, AND HIT IN UNDER AN HOUR

Most home sim owners install this projector themselves in 30-60 minutes. Mount it, run one HDMI cable to your gaming PC, plug in power, press the auto-adjust button, that's it. If you've installed a ceiling fan or a TV mount before, this is easier. If you'd rather not DIY, our SimSquad team walks you through the whole install on a call.

What is the BenQ LK936ST 4K?

The BenQ LK936ST is a commercial-grade 4K UHD laser short-throw projector engineered for elite golf simulator installations. 5,100 ANSI lumens, true 4K UHD resolution, 20,000-hour laser engine, full horizontal and vertical lens shift, and BenQ's auto corner-fit keystone correction. This is the projector spec'd in high-end residential sims, dealer show floors, and commercial entertainment installs.

Why Choose the BenQ LK936ST 4K?

Honest framing: the LK936ST is overkill for most home sim rooms, and that's the point. If you have a complex install (sloped ceiling, off-center mount, oversized screen, ambient light you can't fully control) or you're building a commercial-grade sim, this is the right tool. For a standard 120-inch home sim build in a controlled room, the AK700ST 4K covers it at a fraction of the cost. Talk to SimSquad if you're not sure which tier your install actually needs.

Frequently Asked Questions

Yes. The BenQ LK936ST 4K includes BenQ's Auto Adjust corner-fit keystone correction. Mount the projector, press one button, and the unit auto-corrects the image to fit your screen geometry. This is the single most time-consuming step in a typical projector install, and BenQ's auto-keystone eliminates it. Critical install advantage over most competing projectors at this tier.

Most home sim owners install the BenQ LK936ST 4K themselves in 30 to 60 minutes. Mount the projector to your ceiling or floor mount, run one HDMI cable to your gaming PC, plug in power, press the auto-keystone button, that's it. If you've installed a ceiling fan or TV mount before, this is easier. Our SimSquad team walks through any step on a call if you'd rather not DIY.

The BenQ LK936ST 4K has a 0.8 to 1.1 short-throw ratio, which fits most home sim rooms with 8 to 10-foot ceilings and 10+ feet of depth. Specific throw distance depends on your target screen size. SimSquad will spec the right projector based on your specific room dimensions before you buy.

The BenQ LK936ST 4K delivers 5,100 ANSI lumens. For most controlled indoor sim rooms with managed lighting, this is plenty. If your room has significant ambient light, daylight windows, or you're running a 150+ inch screen, talk to SimSquad about a higher-lumen option in the BenQ or Panasonic lineup.

Yes. The BenQ LK936ST 4K has standard HDMI inputs and works with every simulator software platform we ship, including GSPro, E6 Connect, and TGC 2019. Software compatibility is handled by your gaming PC, not the projector. The BenQ LK936ST 4K renders whatever the PC outputs.

The BenQ LK936ST 4K works with standard universal projector mounts including our RoS Ceiling Projector Mount. For low-ceiling rooms where ceiling mounting isn't practical, our SwingShield Floor Enclosure is sized for projectors of this footprint.

Awesome robo-vac/mop with rotating mop head/no pads.
Size: E25 Black
I owned a Narwal Freo for 1 year and it died right after the warranty period was up. Tried replacing the battery but that did not fix the issue so I had to purchase another one. I noticed this eufy had high reviews and the 1 star reviews seemed to be just isolated issues so I purchased this one. Right away I noticed that the instructions/setup was much more simple. Second this one has a big wide mop roller on the front and after mopping I didn't see the mop streaks in circular patterns on the floor like I did with the Narwal as it had two rotating mop heads on the front so the single mop roller seems to be a better solution. Setup consisted of removing protective wrappers off of the tanks and base station, filling up the clean water tank, installing the detergent bottle and plugging it in. Next I downloaded the app and connecting the vac/mop to my network. This was SIMPLE to say the least. From there I could have just clicked clean on the app and it would clean the entire house. However, mapping gives you more flexibility when planning your cleaning ritual. You can define no go zones and clean rooms in any order you choose. I have a shedding dog so I have a separate robovac to clean up the dog hair prior to vac/mopping. This is a MUST with any robovac/mop combo as the dog hair on the floor will mix with the water and detergent and eventually prevent the mop from doing a good job. It will make a mess in the bottom tray of the base station too. I learned this through experience and reading all the one star reviews from customers. Robovac only cleaners last a LONG time. I had one that is still working great for over 3 years. All I had to do was replace the battery so it doesn't have to pause the job to recharge. So the mapping only took 4 minutes and it was pretty accurate. After the mapping I defined the room boundaries and renamed the rooms. Next I sent it off to clean and it did a FABULOUS JOB! No streaks and the floors are clean. The noise level is really low and more quiet than the Narwal. The other thing I noticed is it didn't use up much water to rinse the mop while cleaning. The Narwal used a lot of water and I was always dumping dirty water and adding fresh. I will always have a robomop and robovac as they save me so much time by not having to do this job twice a week. Connectivity to my network is excellent as it's in a location far from the router. This vac/mop is a good value for the money if IT LASTS BEYOND 1 YEAR. I will update this review as necessary and if it fails right after the warranty period I will report and downgrade this review to 1 star. These companies need to learn the importance of reliability and correct these issues. When I first reviewed the NARWAL it had almost a perfect 5 star review from all customers. After the year was up and it failed that star rating went down to 3+ stars. Most reviews reported their robovac/mop just died like mine did after the warranty period. I downgraded my review and reported the issue. I'm hoping this one will last because at the moment I am VERY satisfied with it like most customers. This model has been on the market much longer at the time of purchase so I would suspect if there were any reliability flaws they would have been addressed and corrected by now. We shall see. At this time I highly recommend!!

Excellent Robot Vacuum, Especially for the Price
Size: 11S, Size: 11S
I have been an iRobot Roomba buyer since 2007. My last Roomba bit the dust this month, and I did a ton of research before buying a replacement. I went with the Eufy for a few reasons: price point, cleaning power, quietness, and sleek design. Price: Very reasonable. Almost reasonable enough that I'd consider getting another one for my second floor. For now I'll just carry it upstairs. Cleaning power: This thing sucks... It's suction is much stronger than my Roombas have had. It picks up so much dust and pet hair. We do a full vacuum every other week with my Dyson, so I think of the robot vacuum as a supplemental vacuum. I was shocked at how much was in the dustbin after it's inaugural cleaning! The picture attached to this is from that cleaning. It also gets a ton of dust in the little dust filter. In one of the video reviews I watched, the reviewer said it didn't pick up anything in that dust filter... So maybe my carpet is particularly dusty, because it has a thick layer after each cleaning. Quietness: I work from my home office, and this thing is quiet enough that I don't even turn it off during conference calls. This might be the thing I am most impressed with. My last Roomba was LOUD-- you couldn't even have a conversation with someone in the same room, let alone someone on speakerphone. Sleek design: I love/hate this. It definitely looks modern and cool, and more like an art piece than an appliance, but it shows all my finger prints, and now I keep a glasses cleaning cloth nearby so I can rub it down. I suppose if I only use the remote and never pick it up, this won't be an issue. A few considerations: I was hoping to find a robot vacuum that wouldn't eat my carpets' tassels, but I don't think that vacuum exists. I have only used the Eufy 4 times so far, and it doesn't always get its brushes wrapped around the long tassels, but it does sometimes. It seems to realize it sooner than my Roomba did at least. The Roomba would sometimes rip gobs of them off in a single cleaning. I try to tuck them under the edge of the rug and that doesn't seem to bother Eufy. It has pulled off probably 2 tassels so far. The cleaning pattern seems pretty random. I saw some other vacuums that chart out complex maps of your home, and Eufy doesn't seem to do that. But, it doesn't seem to matter, because it still hits every spot in the rooms. I'm a little concerned about durability. My Roombas ran for many, many years with easily replaceable parts. We'll have to see if Eufy has the same longevity. All in all- I'm very happy with my purchase and definitely recommend it!

Robot Vacuum With Decent Cleaning but Too Much Maintenance
Size: E28
This robot vacuum was fairly simple to set up, and the battery life is actually pretty good. When it comes to cleaning, it does a solid job picking up dirt and debris, and overall the suction works well for everyday vacuuming. However, the navigation and sensors really missed the mark for me. It struggled to recognize certain items around my house. For example, the mat under my cat’s food bowl kept getting caught because the vacuum didn’t detect it properly. It also had trouble recognizing furniture like my ottomans and would repeatedly run into them. Another issue was how it handled different floor types. It’s supposed to be able to recognize surfaces like carpet versus hard flooring, but that didn’t always work correctly. At one point it even tried cleaning my carpet when it shouldn’t have. It also struggled with room detection and didn’t consistently recognize different areas of my home, even when placed directly in them. I bought this hoping for more of a “set it and forget it” type of appliance since I work a lot and wanted something that would keep my floors clean without much attention. Unfortunately, that wasn’t my experience. I often had to redo the mapping or move the vacuum around so it could recognize spaces and objects properly. There were a few positives though. The app is very helpful and easy to use, and the vacuum communicates clearly through notifications. It lets you know when things like the water level or cleaning bin need attention, which I appreciated. Maintenance like emptying it isn’t required very often either. It’s also a little noisy. Not extremely loud, but it talks frequently and you definitely know when it’s running. Since I work third shift and sleep during the day, that was a bit frustrating. Another issue was that it struggled to cross small entry thresholds between rooms. Even a small lip between rooms would sometimes stop it from moving into another space. In the end, I decided to return it. While it does vacuum fairly well, the navigation issues and constant adjustments made it more of a hassle than a convenience. For the price, I expected something more hands-off, and unfortunately it required more attention than it was worth for me.

Great and Easy to Use!
Size: 11S
Background: I have a shedding dog, so I bought this in hopes that by running it every-day, it would pick up on some of the dog hair on the floor. What I like: -VERY easy to use. -easy to follow instructions -has a sticker on the bottom so if it ever stops and beeps, you can flip it over and it says exactly what the beeps mean (one beep means one thing, two beeps means another--which is SUPER helpful!). -color on top clearly shows what mode it is in (blue-ready to go, orange-needs to charge, red-problem to fix-such as emptying the tray). -very quiet. I can work on stuff with it in the room and it does not bother me at all (my dog also does not mind it). -works great on white carpet and easily transitions from my living room to dining room (which has a slight bump). -when its low on battery, it does not die where it is at, it just turns off the vacuum then finds the home doc and charges itself. -just works really well. I run it everyday and I am impressed by how much stuff it gets (especially when it goes under things such as the couch). -if it gets caught on a cord, it usually takes 5-10 seconds but then it stops the suctioning and moves away (releasing the cord or other item). However if you have a small cord you should put it up (and you should regardless, I just noticed it doing this a few times and thought it was neat, but I do try to pick up all cords). What could be improved: -nothing really in particular to this. -It does not work well on anything black, but this is true for all robot vacuums. It sometimes gets stuck when it goes on the black carpet we have with the black chairs (I suspect because it can not detect them), but this has not happened often. My dog has a black mat for her food and water and it always bumps into it and spills the water, but again, this would occur with any robot vacuum. -Also, make sure the doc is against a wall because otherwise it will move and never charge (self explanatory, but I did not do the first time and it kept trying to doc and was just pushing the doc around the floor). -Finally, you do have to dump out the vacuum particles almost every time you run it (if you do a full circle/battery cycle). It is really easy to dump and beeps when it needs to be emptied. Again, nothing really negative, just something to note. Overall, I really like this! It does a nice job cleaning up the dog hair and other things that get on my floor and saves me a lot of time not vacuuming daily. If you have a dog, I would watch them with this first before you use it. My dog was initially scared of it but sniffed it's "butt" and now they are cool and she does not mind it at all. Pleased with this product and would recommend! :) **UPDATE** On another note, Eufy has amazing customer service! I received an email from them addressing each of my "what could be improved" components with more information on the product. Very impressed.
