Need a longer USB-C cable for your Acer XV272K LV, but want to keep its high refresh rate? We tested that connection with our 15m CABLETIME CT-ACMU4-ZB15 full-function USB-C active optical cable.
The result: 3840 × 2160 at 160Hz, with video playing normally on the monitor. Windows confirmed that mode for both the desktop and the active signal, using RGB, 8-bit color and SDR.
What worked in our 15m test
| Test detail | Our setup and result |
| Monitor | Acer XV272K LVbmiipruzx; rear-label part number UM.HX2CN.V04 |
| Cable | CABLETIME CT-ACMU4-ZB15 / CUA4T, 15m USB-C to USB-C AOC |
| Computer | Lenovo ThinkPad running Windows; the display was connected to Intel Iris Xe Graphics |
| Connection | Laptop USB-C → cable Source end → 15m cable → Acer USB-C input |
| Desktop mode | 3840 × 2160, 160Hz |
| Active signal mode | 3840 × 2160, 160Hz |
| Color mode | RGB, 8-bit, SDR |
| Picture | Video playback displayed normally |
We used the full 15m cable coiled on the bench, with the monitor and laptop next to each other.
We checked the active signal as well as the desktop setting: it identifies the output being sent to the monitor. Both readings matched, as shown below.
Our test recording with an enlarged Windows settings callout: desktop and active signal at 3840 × 2160, 160Hz.
Our result applies to the monitor, cable and Windows setup above in SDR. The 160Hz reading is the display signal, not a measurement of game or video frame rate. We did not measure input latency, HDR, variable-refresh operation, simultaneous USB transfer speed or charging.
Why choose this CABLETIME cable?
The CT-ACMU4-ZB15 / CUA4T is a 15m USB-C male-to-male active optical cable, combining optical fiber and copper wiring for display video and USB data. It supports up to 8K at 60Hz with compatible equipment. For an XV272K LV owner, the more relevant result here is keeping a 4K 160Hz signal over the full 15m cable.
Play fast-moving games at 4K
In racing games, that means detailed scenery alongside smoother motion as you turn into a corner. In fast-paced shooters, a high refresh rate can make movement easier to follow. 4K provides the image detail; 160Hz lets the display update more often than 60Hz. To benefit from those extra updates, your computer must also render the game at a high frame rate. Intel explains why the CPU, GPU and display need to work together.
Our test checks the cable connection needed for that setup. We confirmed the 4K 160Hz output with our ThinkPad; we did not benchmark games on it. A longer cable cannot raise your game's FPS, but this result shows that the tested connection carried the high-refresh 4K mode.
Use the same screen for work and games
You may want 4K for detailed documents, spreadsheets or design work during the day, then switch to games after work. High refresh rates also have a use on the desktop: scrolling through a long page can look more fluid, as Microsoft's refresh-rate guide explains. You don't need to play games to appreciate that difference.
Watching a 24fps or 60fps video, however, does not turn it into 160fps. If films or static presentations are your main use, 160Hz alone is not a strong reason to choose this cable.
Reach your monitor without moving the computer
The 15m length matters when the computer and display cannot sit together—for example, a compatible computer on a side workstation feeding a separate gaming desk, or a cable route that runs behind cabinets and around the room.
In our setup, one USB-C cable connected the computer directly to the monitor, without an HDMI or DisplayPort adapter. The cable needed no separate power adapter, so there was no extra cable power supply to place along the route. The monitor and computer still need their own power arrangements, as explained below.
That is the buying reason we tested for: more reach while retaining high-refresh 4K output on this Acer setup. Measure your route and leave slack at both ends; choose a shorter cable if it already reaches comfortably. The cable includes a two-year warranty.

Check your USB-C port and power arrangement
Your computer needs DisplayPort Alt Mode video output with support for the resolution and refresh rate you want. The monitor's USB-C input must support that mode too. A USB-C connector alone does not establish those capabilities; check your computer's specifications. VESA explains USB-C display support here.
We used the XV272K LVbmiipruzx unit identified in the results table. Compare that full model with yours, because the broader XV272K name covers different versions. Our result is a tested combination, not a promise that every USB-C computer or XV272K variant will run at 160Hz.
Power the monitor separately. This model carries charging power from Source to Display; it is not a monitor-to-laptop charging connection. Keep a separate laptop power connection when needed.
Connect the Source end to your computer
Computer USB-C video output → Source → CT-ACMU4-ZB15 → Display → Acer USB-C input
The monitor end connects to USB-C. The monitor's power connection remains separate.
- Connect the end marked Source to the computer and Display to the Acer monitor's USB-C input.
- Select the monitor's USB-C input. In Windows, go to Settings → System → Display → Advanced display and select the Acer monitor.
- Choose 160Hz, if available, then check that both desktop and active signal show the intended resolution and refresh rate.
If this matches the connection you need, choose the 15m CT-ACMU4-ZB15. The link opens with 15m selected; check the length before adding it to your cart.
