Will the video drop out when dragging windows quickly?

No. Please refer to the test video. In our testing, this product has approximately 1–2 frames of latency (about 1/60–2/60 of a second).

Will text look blurry? Will dark areas show banding or blocking? Will fast motion show pixelation or image breakup?

HKM01-4K6G uses light compression, but it should not create visible blur under normal viewing conditions. Banding, blocking, and motion breakup are not expected.

You can also refer to our image-quality test video. In the comparison, the lower-left is the extender with heavier compression, while the upper-right is HKM01-4K6G.

Can I connect a webcam to the receiver? Is USB limited to keyboard and mouse only?

Yes. HKM01R-4K6G supports webcams. It works with not only keyboard and mouse, but also most USB 2.0 devices. USB 3.0 is not supported.
