Thank you for viewing! I will pack it carefully and ship it in simple packaging. This product is ☆彡 Unused ☆彡 There may be small scratches, scuffs, or stains. Please judge the condition and size of the product from the photos. Please consider only if you understand. *Please also read the profile (^^) Bi-directional EDID, source can be male or female connection. Pixel format: YCbCr 4:4:4, 4:2:2, 4:2:0, RGB. Audio: 2.1. You can turn off a TV multi-monitor system without the PC trying to rearrange the desktop for the remaining screen and causing problems (or unplugging the HDMI). The PC won't even notice that one of the screens has disappeared. Supports up to 4k@60fps from Mac Thunderbolt to HDMI. You will know it as the "miracle solution" for Windows that doesn't like 4K displays. Ideal for multimedia setups that always need to "sync" HDMI displays. HDMI lock EDID solves the "loss of sync" problem with multiple HDMI displays. You no longer need to rearrange your desktop every time you turn your TV on or off. The display can be connected to a full-size DisplayPort - HDMI adapter, and this adapter works perfectly. Surprisingly, there are many modes not only for typical 4K (3840x2160) but also for true 4K (4096x2160), with refresh rates from 23hz to 60hz.
