The BenQ LU935ST and LK936ST are easy to confuse because their names and optical specifications are similar. Their displayed images are not the same: the LU935ST is a WUXGA projector with a native 16:10 frame, while the LK936ST displays 4K UHD in 16:9.
That distinction matters more than deciding which model number sounds newer. Use the BenQ LU935ST and BenQ LK936ST listings alongside your intended screen dimensions. This comparison is based on published specifications, not a hands-on test.
The differences to understand first
| Feature | LU935ST | LK936ST |
|---|---|---|
| Display resolution | 1920 × 1200 WUXGA | 3840 × 2160 4K UHD |
| Native image format | 16:10 | 16:9 |
| Rated brightness | 5,500 ANSI lumens | 5,100 ANSI lumens |
| Throw ratio | 0.81–0.89 | 0.81–0.89 |
| Optical zoom | 1.1x | 1.1x |
| Optical lens shift | Vertical and horizontal | Vertical and horizontal |

WUXGA is not 1080p and accepting 4K is not displaying 4K
The LU935ST's 1920 × 1200 image has more vertical pixels than a 1920 × 1080 image and a different native shape. It is still not a 3840 × 2160 display. Keep the displayed resolution separate from the list of input signals a projector can accept.
This is especially important when browsing product descriptions that mention 4K compatibility. A supported input may be processed into a lower-resolution displayed image. Choose the LK936ST when 4K UHD display output is a requirement, rather than assuming the same capability from a compatibility label.
Match the native shape to your planned image
Imagine using the full ten-foot width of a screen. A native 16:10 image would be 6.25 feet tall; a native 16:9 image would be 5.625 feet tall. These are calculated aspect-ratio examples, not recommended screen sizes. They show why image shape deserves its own decision.
On a 4:3 or square simulator screen, neither native frame is an automatic full-surface match. Work through the actual software output and projector settings. Decide which areas of the screen will carry an image and whether other uses, such as movie viewing, require a different format.
Measure the usable screen rather than its border or the enclosure's outside frame. Our golf impact screens offer different sizing options, but the correct selection depends on the picture you intend to display.
Similar throw ratios do not eliminate installation checks
For a preliminary full-native-frame calculation, a ten-foot-wide picture gives an 8.1–8.9-foot lens distance with either model. The matching ratios can make them worth comparing for an existing bay, but they do not establish that every replacement is a direct swap.
Verify the lens position, mounting interface, vertical alignment, ventilation, and cable connections. Optical lens shift helps with positioning, but it has a defined operating range. It should not be used as a reason to skip the manufacturer's installation drawing.
Before selecting mounting hardware, inspect the structure that will carry the load. The bracket, ceiling attachment, and final projector position must work together.
Brightness is a tradeoff, not a complete verdict
The LU935ST has the higher published ANSI-lumen figure, while the LK936ST has the higher displayed resolution. That does not turn the decision into a simple brightness-versus-quality contest. Screen area, light reaching the screen, picture settings, and the viewing position affect the result.
Start by identifying your actual complaint or requirement. If small graphics lack definition on a large image, resolution may deserve more weight. If the screen is washed out by daylight, investigate light control rather than assuming a resolution upgrade fixes it.
Account for the computer and software
A projector should be chosen with the system that supplies the image. Establish the intended output resolution, then check the simulation software's current hardware requirements and the launch monitor's connection requirements.
A complete upgrade may include graphics hardware or a different signal path, not only a new projector. Conversely, a well-matched WUXGA installation may already satisfy a practice-focused room. Compare the total cost against the specific benefit you expect.
Which is the more sensible choice?
Investigate the LU935ST when a 16:10 WUXGA display fits your priorities and the higher published light output is useful. Investigate the LK936ST when 4K UHD detail is an important goal and the computer, screen, and installation can support it.
For either model, a room plan is more useful than a blanket claim that one is always better. Record your visible screen dimensions, lens location, ambient lighting, software, and computer specification before ordering.
Frequently asked questions
Is WUXGA the same shape as 4K UHD?
Not for these models. Their native formats are 16:10 and 16:9 respectively.
Does matching throw ratio guarantee the existing mount will work?
No. Check the mechanical mounting requirements and optical position separately.
Will the higher-resolution model improve launch monitor accuracy?
No. Projection detail and shot measurement are different parts of the simulator.
