OREI HDMI Extender Over Cat5 165ft: 4K@30Hz with IR
This extender transmits Full HD up to 4K@30Hz over CAT6/7 for distances up to 50 meters. It includes a transmitter loop-out for local display monitoring and supports DTS-HD, Dolby TrueHD, and Deep Color. Best for dual-display setups where 4K@30Hz is acceptable and local monitoring matters. Not compatible with HDMI ARC or IP/network streaming.
Who this is for: users who need a simple, wire-friendly extension with a local monitor option and a straightforward setup. Caution: it does not support 4K@60Hz or IP/network streaming, so plan for the lower refresh rate if your source or display requires it.
OREI HDMI Over Ethernet Extender 230ft: PoC, HDR
Extends HDMI signals up to 230 feet over a single Cat6/7 cable with PoC powering the transmitter. It supports HDMI 2.0a, HDCP 2.2, and 4K@60Hz with HDR10+ and 18Gbps bandwidth for crisp visuals. Best for living rooms and conference spaces needing long reach without extra power outlets at the display end.
Who this is for: buyers seeking the longest single-cable run with high-quality 4K60 HDR, while keeping the receiver powered from the display side. Caution: only the transmitter uses PoC, so plan power access at the source end.
OREI 4K@60Hz HDMI Over Cat6 Balun 165ft: Loop Out, EDID
This 4K@60Hz extender over CAT5e/6/7 supports HDR, 18Gbps bandwidth, and 12-bit color. It includes an HDMI loop-out and built-in EDID management to optimize compatibility between source and display. Best for high-speed color and HDR-rich content in home theaters or meeting rooms.
Who this is for: those who require 4K60 with reliable EDID control and a local loop-out. Caution: ensure your source and display both support 4K60 with HDCP 2.2 for best results.
OREI 4K KVM HDMI Extender Over Ethernet
This KVM-enabled extender supports PoC and offers two-way IR for remote control. It enables USB 1.1 KVM with LPCM, 7.1 channel audio, and supports 4K60 4:4:4 across a long CAT link. Best for setups requiring keyboard/mouse access from the remote display and flexible control.
Who this is for: users needing a true KVM workflow over Ethernet, especially in server rooms or multimedia studios. Caution: functionality relies on compatible KVM peripherals and proper USB routing across the link.
OREI 4K HDMI Over Ethernet Balun UHD-EXB400R-K
Note: OREI HDBaseT models typically require matching transmitter and receiver from the same brand due to chipset differences. This model uses HDBaseT for long-distance UHD signals with loop-out, HDR, and IR control. Best for standardized, brand-consistent installations where component compatibility is ensured.
Who this is for: buyers who prioritize guaranteed chipset compatibility with other OREI HDBaseT units and seamless integration in a single-brand setup. Caution: mixing with non-matching OREI HDBaseT devices may cause incompatibilities.
Buying Guide: Key Considerations For HDMI Over Ethernet Extenders
- Distance And Resolution: If you need 4K at 60Hz, verify the model supports HDMI 2.0/2.1 with HDCP 2.2 and 18Gbps. For simple 4K at 30Hz, longer runs are often possible with lower bandwidth requirements.
- Power Delivery: Decide between PoC (power at the transmitter) and full AC adapters at both ends. PoC simplifies wiring but ensure the transmitter location has power access.
- HDR And Color: Look for HDR10+/Dolby Vision support and 4:4:4 chroma for crisper color. Some extenders cap at 4:2:0 or 4:2:2 in lower-cost models.
- EDID Management: Built-in EDID features help the source select compatible resolutions, reducing display flicker or incompatibility issues.
- Local Loop-Out: A transmitter loop-out lets you monitor content locally while the signal is extended. Consider if this feature matters for your installation.
- IR And KVM Features: If you need remote control of a set-top box or media player, choose IR pass-through or a KVM-enabled extender. Ensure proper compatibility with your control devices.
- Compatibility: HDBaseT and CAT-based extenders vary by brand. Stick with a single brand when relying on HDBaseT for best reliability, unless you have verified cross-brand compatibility.
FAQ
- What is HDMI over Ethernet used for?
It extends HDMI signals over long distances using network-grade cables, reducing bulky HDMI runs while maintaining 4K and HDR where supported.
- Do these devices support 4K at 60Hz?
Some models do (HDMI 2.0/2.1, HDCP 2.2), while others are limited to 4K@30Hz. Check the specific product features before purchasing.
- Is power over cable required?
Many extenders offer PoC with power at the transmitter. Some require both ends to be powered or an external adapter for the receiver.
- Can I mix brands?
HDBaseT devices from different brands may not interoperate reliably due to chipset differences. Best results come from matching brands for transmitters and receivers.
- What is EDID and why does it matter?
EDID lets devices negotiate the best resolution and refresh rate. Proper EDID management helps prevent display issues and improves compatibility.
- Do these extenders support audio formats like Dolby TrueHD?
Many models support high-fidelity audio formats including Dolby TrueHD, DTS-HD Master Audio, and LPCM. Always verify the exact audio formats listed in product specs.
