The Da-Lite Tensioned Large Cosmopolitan® Electrol® is purpose-built for premium large-venue environments where a flawless, warp-free projection surface is non-negotiable. This electric screen is designed for both ceiling and wall mounting, offering a sophisticated balance of form and function to complement modern interiors. With a broad palette of finishes and veneer options, it can be customized to blend seamlessly with décor while delivering world-class image clarity. The crown jewel of this system is the In-the-Roller motor mounting with a Tensioning Cable System, which works tirelessly to prevent warping and maintain even lateral tension across the entire screen surface. In short, it’s a premium solution for auditoriums, lecture halls, conference centers, and high-end home theatres where image quality and reliability matter as much as aesthetics.

  • Warp-free performance and precise image alignment: The Tensioning Cable System, combined with the In-the-Roller motor mounting, ensures consistent even tension across the screen. This design minimizes side-to-side distortion and edge curl, delivering a perfectly flat viewing surface that stays true from the first frame to the last. Whether you’re displaying bright 4K content or subtle, high-contrast slides, you’ll enjoy sharp details and uniform brightness without distracting warping or bowing.
  • Ceiling or wall mounting for flexible installations: The Cosmopolitan Electrol is engineered for versatile mounting options, making it ideal for retrofit projects and new-builds alike. Whether you’re upgrading a front-of-house cinema, a corporate auditorium, or a large classroom, the screen’s robust mounting system accommodates your space with secure, clean lines and minimal intrusion into sightlines.
  • Custom finishes and veneer options to match your environment: Choose from a broad range of finishes to harmonize with architectural details, decor, and room color schemes. The Decora-style trim adds a refined, professional look that integrates seamlessly with contemporary interiors, giving the installation a polished, showroom-ready appearance.
  • Large-diagonal projection surface for immersive viewing: At 189 inches diagonal, this Cosmopolitan Electrol screen delivers a commanding image size that’s ideal for large venues, enabling comfortable viewing from a wide audience. The expansive format supports immersive presentations, engaging corporate events, and cinematic demonstrations with crisp, uniform brightness across the surface.
  • Reliable, quiet operation with flexible control options: The Electrol screen features an electric motor designed for smooth, quiet operation and dependable performance. It’s compatible with hand-held remotes or wall switches, and is suitable for installations where touchless control or centralized room automation is preferred. This reliability translates to fewer interruptions during important presentations and easier long-term maintenance.

How to install Da-Lite Tensioned Large Cosmopolitan Electrol 189"

Installing the Cosmopolitan Electrol 189" screen begins with planning the mounting location and ensuring structural support for the weight of the case and roller. Start by locating structural anchors in the ceiling or wall, using a stud finder or appropriate mounting hardware to support the screen’s load. Attach the mounting brackets securely, referencing the SKU-specific installation manual for precise screw sizes, spacing, and torque settings. Run power to the location in accordance with local electrical codes, ensuring a dedicated circuit and appropriate receptacle or hardwired connection for the motor. With the brackets in place, carefully lift and hang the screen housing, ensuring it is level and plumb for proper operation. Connect the motor wiring and test the projection surface to confirm full travel range and smooth retraction. Once baseline operation is confirmed, calibrate the tensioning system per the installation guide to optimize warp resistance and edge stability. Finally, perform a room test with your projector at multiple seating positions to verify image brightness, color accuracy, and viewing comfort, adjusting the projection setup as needed. Routine maintenance includes inspecting mounting hardware, testing the motor function periodically, and cleaning the surface with manufacturer-approved products to preserve contrast and clarity.

The Best!
This thing is amazing! Worked right out of the box. No drivers to install, no confusion, just plug and go. I'm using this hub to connect a mouse, a keyboard, and a monitor to my 2025 MacBook Air (M4). Before buying this I bought a complicated, powered hub for 2x the price and wasted multiple hours trying to get the $%^&(*& thing to work, which it never did. If you want to run a display and a few peripherals, this Startech hub is the absolute best bang for your buck.

Quality Control Issues
I want to like this dock, I really do. I purchased it with the intention of using it as a hub for my phone + usb-c external display. The pass-through charging never worked on this dock. Tried multiple cords and tested the dock with nothing plugged into any of the USB ports -- all of the power disappears somewhere onto the hub and the actual charge rate on my phone slows to a trickle. With nothing connected, it estimates >24hrs to charge from 30% to full. The plus side is that the usb ports do work, though the usb-c display went from 100% reliability to <50% within a few months of purchase. Extremely frustrating.

This is the one, buy it for DeX!
Looking for a compact USB hub to connect your laptop or Samsung DeX capable device? Buy this one! I've tried multiple similar items from name brands, and they work fine as a USB and port hub, but this one is able to support power delivery and display data through a single (capable) USB-c cable. I assume because it is noted to be capable of some combo of USB 3.2, PD 3.0 pass through and DP 1.4 alt mode. I'm not quite sure which one(s) make it possible, but it works for an HP Spectre laptop and Galaxy phone. Only improvement suggestion is to add an additional 10gb capable USB-C port in place of the three USB-A ports, but that's being super picky. Thanks StarTech for building another unique solution for connectivity challenges.

Usb-c passthrough started failing about a year into ownership.
This had the potential to be the perfect accessory for my M4 MacBook Air. It is very difficult to find dongles like this that support display passthrough via usb-c (meaning that if you have a usb-c display you can connect it to this and use the display). When it did work, I was able to power a triple monitor setup with my 2 port Macbook Air (with one display being driven by a displaylink adapter). If this product had continued to work as advertised, is would be a 5 star review. But after maybe a year of VERY sporadic use (I use this maybe once a week because my MacBook Air is not often docked) the usb-c passthrough is already failing. On a display I use every day with a different machine (a 16" MBP that has enough ports to not need any adapters) and the display and cable work perfectly fine there so I can only assume that it is this specific adapter which is failing. If I insert the connector several times, sometimes I can get it to work but my success rate just keeps dropping. There was no other reason to spend this much on an adapter that without usb-c passthrough offers just 3 usb-a ports like most much cheaper adapters. So to say I am disappointed is an understatement.

Expensive, but it works
The good parts: Yup, this works with DP alt mode, single cable use works for most devices I tried (steam deck, laptop, odin mini 2) even without the hub powered through the power in on the hub, I even got it working without external power to either the hub or my small usb-c monitor. However, some devices like my phone likely didn't give enough power for it to work without another power source. On my phone it worked for some usb devices without external power, but the dp alt mode didn't do work. DP alt on my phone works just fine with external power connected to the hub. Powering it with a small but powerful power bank worked fine, but lower power power banks might not keep up especially if the monitor isn't getting it's own power. It only takes a watt or two of power for the hub itself from some quick and dirty measurements charging my laptop through the pd-in on the hub. As for the rest of it, the three usb 3 ports means you should be enough to get by for any use case, though you may need more dongles or adapters to get the type of connections you need, but quite usable as-is for a lot of purposes. Basically it does what it says, there really is no other hub currently that can do pd alt mode, only big docks which need power supplies. The ok parts: *When it isn't powered* I noticed that with a monitor already plugged in, plugging it into a device would lead to the monitor not being initialized. But plugging the hub into the device first before connecting the monitor worked. No issue when it was powered. You can use this to get display out and charge with a Nintendo switch, but if it's not powered through the pd-in it probably wont switch to TV mode and output video, not sure if that's because of power or software reasons. This is a nitpick, but if you care about the feel or aesthetic it's noticeably bland. The case is plastic and there seems to be no weighting on the inside, it's very light, which can feel cheap but it's not like adding weights would functionally make it better, the case also has a bit of a harsh feeling where it's joined, but it does feel solid and durable enough. It's clearly function over form, just barely meets the minimum bar imo. The bad part: You already saw, but the price is a bit steep for a hub (at $80). I'd love to see it at 60 or even 40 instead, I hope more similar hubs pop up for competition. In summary: It does what it says, if you know you want this and what it is then get it, I feel like it shouldn't cost this much, but it's quite usable and for now it's the only option for a DP alt mode hub. Minus a half star each for subpar presentation and price 4/5
