Best HDMI Extenders and Video Converters for Long Cable Runs

The best HDMI extender for most people is the AV Access 4KEX70-L, because it sends a clean 4K60 signal over a single network cable and adds IR, CEC and PoE so one power supply feeds both ends. If you need to bring a broadcast or camera feed into a normal monitor, the Anber-Tech SDI to HDMI converter is the budget answer and the Blackmagic Micro Converter SDI to HDMI 12G is the premium one. For a clean wall behind a mounted TV, the ECHOGEAR in-wall kit hides both power and low-voltage cables.

HDMI over Ethernet, SDI conversion and in-wall cable management sound like three different shopping trips, but they solve one problem: getting a video signal from where the source is to where the screen is, without a messy cable run. This guide treats them together. It picks seven products by the job they do, adds four alternatives, and explains the numbers that matter, such as distance at each resolution, HDCP versions and chroma subsampling. Every product is a real listing in the shop section of this site. Specs come from the listing, the maker’s page, or an independent source we name; anything unpublished is marked “not listed.” Always check your own setup against the maker’s compatibility notes, because source devices, displays and cable quality all affect results.

Quick Comparison Table

1. AV Access 4KEX70-L: Best Overall HDMI Extender

• HDBaseT-style extender over one Cat6a or Cat7 cable (the maker also says Cat5e works)
• 4K at 60Hz up to 40 m (130 ft) and 1080p at 60Hz up to 70 m (230 ft), per the maker
• Bi-directional PoE: one end powers the other
• 2-way IR, RS232 and CEC pass-through
• Supports Dolby Atmos, DTS:X, Dolby TrueHD and DTS-HD Master Audio per the listing; 4K60 uses 4:2:0 color per maker information

Best for: Home theaters, projectors, classrooms and offices where the source sits in a rack and the display is a long cable run away. Skip if: you need 4K60 at 4:4:4 over 230 ft; AV Access sells a newer model for that.

The “230ft” in the listing name applies to 1080p. At 4K60 the maker’s figure is about 130 ft, which still covers most rooms. That honest distance caveat is common across extender listings, and it is the single most important thing to check before you buy. The extender uses HDBaseT-lite technology, so the signal is not compressed and you should not see added delay from a codec. PoE means a single power adapter is enough if the transmitter and receiver are both near an outlet on one side.

IR pass-through matters in installations where the remote can not reach the source. With IR in both directions you can point at a hidden receiver and still control the box in the rack. CEC pass-through helps TVs and media players wake together. As with all extenders, use solid copper network cable, not copper-clad aluminum, and keep the run free of splices and cheap wall jacks.

Pros: Uncompressed HDMI; bi-directional IR and PoE; honest distance range; wide audio format support. Cons: 4:2:0 color at 4K60; older HDMI generation; premium tier cost.

2. OREI HDMI Over Ethernet Extender (4K60, 230 ft): Best Long-Distance Value

• HDMI 2.0 at 18 Gbps with HDCP 2.3
• 4K60Hz, 12-bit color support, per the listing
• Up to 230 ft over Cat6, with PoC (power over cable)
• One-way IR, HDR HLG, metal housing and ESD protection
• Audio: LPCM, DTS and Dolby Digital per the listing

Best for: Buyers who want a modern HDMI 2.0 spec at a mid-range tier and a long run. Skip if: you need bi-directional IR or RS232 control.

The OREI extender is a good example of why you should read the distance claim closely. Listings often quote the maximum range at a lower resolution, and the 4K60 range can be shorter. The listing title mentions 230 ft; check the manual for the exact distance at 4K60 and with your cable category before you pull wire through a ceiling. Cat6a or Cat7 usually gives the best margin.

The metal housing and ESD protection are practical features for equipment racks and wall-plate installs. PoC means only one end needs an adapter, and one-way IR lets you send a remote signal from the display location back to the source. If you need two-way IR control, look at a model that lists it.

Pros: HDMI 2.0 and HDCP 2.3; PoC; metal build; mid-range tier. Cons: One-way IR; 4K60 distance should be verified; limited control options.

3. Steetek HDMI Extender (1080p, 164 ft): Best Budget Extender

• 1080p at 60Hz up to 164 ft over Cat5e, Cat6 or Cat7
• PoC and EDID support
• Transmitter and receiver included
• HDMI 4K: not supported
• Model reference: HT202P

Best for: Classroom projectors, signage and older 1080p televisions. Skip if: your source or display is 4K.

Plenty of installations still run at 1080p, such as presentation rooms and menu boards, and paying for 4K there makes little sense. A 1080p extender is simple and low cost, and the EDID support helps the source recognize the display so it outputs the correct resolution. Because the tier is budget, keep expectations realistic: build quality, noise immunity and long-term reliability are not described in the listing.

Use a continuous, solid-copper cable and avoid running it parallel to mains wiring for long stretches. Interference is the most common cause of sparkles on extended HDMI.

Pros: Low cost; 1080p at 164 ft; PoC; EDID. Cons: No 4K; fewer protections; control features not listed.

4. Anber-Tech SDI to HDMI Converter: Best Budget SDI Converter

• Accepts 3G-SDI, HD-SDI and SD-SDI with auto format detection
• Audio de-embedder; the title says stereo, and other listings mention up to 8 channels
• SDI loopout (equalized and re-clocked, per the seller)
• HDMI output up to 1080p; 4K is not supported
• Powered over USB 5V (adapter included per the seller)

Best for: Camera feeds, church video and event streams going to an HDMI monitor, capture card or projector. Skip if: you need 4K or the reverse direction (HDMI to SDI).

SDI is the cabling standard in broadcast and professional video. It uses a BNC connector and can run hundreds of feet on coaxial cable, which is why cameras use it. A television or capture card uses HDMI, so a converter bridges the two. The loopout lets you pass the SDI signal on to a second device, such as a recorder, without a splitter. The audio de-embedder pulls audio embedded in the SDI signal out into the HDMI stream.

The key buying detail is the supported SDI rates. 3G-SDI covers 1080p at 60Hz. If your camera outputs 4K over 6G or 12G SDI, this converter will not display it. Check the camera’s output format before you buy.

Pros: Low cost; loopout; auto detection; compact. Cons: 1080p limit; one-way; audio details differ between listings.

5. Blackmagic Design Micro Converter SDI to HDMI 12G: Best Premium Converter

• One 12G-SDI input and one 12G-SDI loop output
• HDMI 2.0 output, supporting SD, HD, Ultra HD and 4K up to 2160p60, per Blackmagic
• Auto-detects formats from 270 Mb to 12G
• 33-point 3D LUT for monitor calibration
• Powered by USB-C; the version with a power supply is a separate model; this listing’s title does not mention one

Best for: 4K cameras, switchers and professional workflows that need reliable conversion. Skip if: you only handle 1080p; a cheaper converter does the same job.

The step up in cost buys format coverage and build. A 12G-SDI input accepts everything from standard definition to 4K60 over a single BNC cable, and the HDMI 2.0 output feeds a 4K monitor. The USB-C port also handles settings and firmware via Blackmagic’s utility. Power draw is low, so a laptop, a monitor port or a wall adapter can supply it.

One practical point: the listing here is the version sold without a power supply, so you need a USB-C power source. If you want one in the box, search for the model that includes a PSU.

Pros: 4K60 capable; loop output; LUT support; maker documentation. Cons: Premium tier; power supply not included in this listing; overkill for 1080p.

6. ECHOGEAR TV Cord Hider In-Wall Kit: Best for a Clean Wall

• Dual-outlet in-wall power module for wall-mounted TVs
• Includes a 6.25 x 8 x 3.95 inch module, wall template, saw and a 6 ft extension cord
• Handles power and low-voltage cables
• Installation time and wall type limits: see the maker’s instructions
• Cable ratings for low-voltage runs: use in-wall rated cable

Best for: A wall-mounted TV where you want no visible power cord. Skip if: your wall has a fire block, plumbing or a stud directly behind the cutout, or you rent and cannot cut the wall.

A cord hider kit solves the last visible cable on a mounted television. The kit mounts a recessed outlet behind the TV and a second box lower on the wall, so the plug and cable are hidden. The template guides the cutout, and the saw cuts drywall. Always check for studs and wiring with a stud finder before cutting, and use cable rated for in-wall use. Many jurisdictions have rules about in-wall power extension, so read the instructions and your local code, and consider hiring an electrician.

An in-wall kit does not replace an HDMI extender, but it pairs well with one. A neat setup might route a thin HDMI or Ethernet cable to the receiver behind the TV, with the power module beside it.

Pros: Clean look; includes tools; dual outlet; mid-range tier. Cons: Requires cutting drywall; code and wall limits; installation takes planning.

7. Mount-It! In-Wall TV Cable Concealer Kit: Best Three-Outlet Option

• Recessed power with a triple outlet
• 9 ft cord and a hand saw included
• Designed for organized TV and home theater setups
• Low-voltage cable pass-through plates: see the listing details
• Dimensions: not listed in the title

Best for: Wall-mounted TVs with a soundbar, streaming box or game console that all need power behind the TV. Skip if: the TV mount sits tightly to the wall and the recess box would not fit.

A third outlet is useful when the TV, soundbar and streaming box all need power behind the screen. The 9 ft cord gives more flexibility than a shorter lead when the wall outlet is not directly below. Like the ECHOGEAR kit, it is a do-it-yourself install and should be done with care around studs and electrical wiring.

If you only need a place to pass low-voltage cables, such as HDMI or Ethernet, a simple brush wall plate is easier and avoids any power-related concerns.

Pros: Triple outlet; longer cord; tools included; tidy result. Cons: Cutting required; moderate cost; dimensions not in title.

Also Consider

OREI HDMI Extender Over Cat5, 4K30, 165 ft

A step-down model with IR, loop out, EDID and PoC. At 4K30 it suits many streaming boxes and 4K signage, but not 4K60 gaming or sports.

SHUITING SDI to HDMI Converter with Loop Out

A 1080p alternative to the Anber-Tech converter with an SDI loop and BNC input. It is similar in capability and tier, so choose based on the exact listing.

VCE Brush Wall Plate Cable Pass-Through, 2-Pack

A single-gang plate with a brush opening for low-voltage cables. It is a simple, low-cost alternative if you only need to pass HDMI or Ethernet through the wall.

OREI UltraHD 1×2 HDMI Splitter

A splitter that copies one HDMI source to two displays. It is the right tool when you need one source on two screens, rather than a longer run.

How We Chose

This guide is research-based. We did not personally use these products. We started with the listings in the shop section of this site and cross-checked them against the manufacturers’ product pages where available, including AV Access and Blackmagic Design’s published specifications. We used independent explanations of HDBaseT, HDMI versions and SDI standards to describe how each technology works.

We selected products by job and limited each brand to two picks. We preferred listings that state resolution, refresh rate and distance clearly, and we flagged missing information as “not listed.” We did not use star ratings, review counts or sales ranks, and prices are described in tiers only.

Buying Guide: How to Choose HDMI Extenders and Video Converters

1. Decide on resolution and refresh rate first

1080p at 60Hz needs far less bandwidth than 4K at 60Hz. A 1080p extender is fine for classrooms and signage. For 4K movies at 24 or 30 frames per second, a 4K30 extender may be enough. For 4K60 gaming or sports, choose a model that lists 4K60 and read its chroma subsampling: 4:2:0 is fine for video but softer for text, and 4:4:4 is best for computer use.

2. Read the distance at your resolution

Maximum distance depends on resolution and cable. A common pattern is about 130 ft at 4K60 and 230 ft at 1080p. Cat6a or Cat7 gives better margin than Cat5e. If your run is near the limit, choose a unit with a safety margin, not one that barely reaches.

3. Check HDCP and EDID

HDCP is the copy protection used by streaming boxes and Blu-ray players. An extender should list the HDCP version your source uses, such as 2.2 for 4K. EDID support lets the source read the display’s capabilities, which reduces blank screens and wrong resolution.

4. Pick the right SDI rate

HD-SDI covers 720p and 1080i, 3G-SDI covers 1080p60, 6G covers 4K30, and 12G covers 4K60. A converter must support the rate your camera outputs. Also decide whether you need a loopout or audio de-embedding.

5. Plan the cable path and the wall

For in-wall installs, use cable rated for in-wall use, follow the maker’s instructions for power modules and consider an electrician for power work. Keep network cable away from mains wiring where possible, and leave a service loop at each end.

Which Setup Fits Which Room?

The distances above are planning ranges, not guarantees. Add a margin of at least 10 percent, because splices, wall jacks and bends in the cable all subtract from the maker’s figure. When two products both fit, the one with the clearer written specification is usually the safer buy, since you can compare its claims against your own source and display before you commit.

Common Mistakes

• Buying on the headline distance without checking the resolution it applies to.
• Using flat or copper-clad aluminum network cable for extenders.
• Forgetting that SDI converters are one-way unless the listing says otherwise.
• Cutting a wall before checking for studs and wiring.
• Putting a network switch between an HDBaseT transmitter and receiver. Most point-to-point extenders do not work through a switch.

Frequently Asked Questions

What is the best HDMI over Ethernet extender?

The AV Access 4KEX70-L is a strong all-round choice for 4K60 and controls such as IR and CEC. If you need a lower-cost option, the OREI extender or the Steetek 1080p unit fit simpler setups.

Can an HDMI extender work through a network switch?

Most point-to-point HDBaseT-style extenders do not. They need a direct cable between the transmitter and receiver. Systems that work through switches use different technology, usually labeled as HDMI over IP.

Do I need Cat6 or Cat7 for HDMI over Ethernet?

Cat6 is the usual baseline, and Cat6a or Cat7 gives extra margin for 4K at long distances. Many makers say Cat5e works at shorter lengths, so check the manual for your resolution.

What does an SDI to HDMI converter do?

It takes a professional SDI video signal from a camera or switcher and outputs HDMI for monitors, capture cards and televisions. Some also pass the SDI signal through a loop output and extract the embedded audio.

Can an SDI converter handle 4K?

Only models that list 6G or 12G SDI input and an HDMI 2.0 output can. The Blackmagic 12G converter does, and the Anber-Tech converter is limited to 1080p.

Is an in-wall cable management kit safe to install myself?

Many people install them, but you should follow the instructions and local code. Check for studs and wiring before cutting, and use in-wall rated cable. If you are unsure about the power part, hire a licensed electrician.

Will an HDMI extender add lag for gaming?

HDBaseT-style extenders are designed to be uncompressed with very low latency, but exact latency is not listed for most models. Competitive players should look for a maker statement on latency and confirm on their own system.

Which One Should You Buy?

Buy the AV Access 4KEX70-L if you want a trustworthy 4K home theater or office run with controls. Choose the OREI 4K60 extender if you want a mid-range HDMI 2.0 unit and your distance is moderate. Pick the Steetek if 1080p is enough and cost matters most. For cameras, the Anber-Tech converter covers 1080p and the Blackmagic 12G converter covers 4K. Add the ECHOGEAR or Mount-It! kit when the goal is a wall with no visible cables.

Measure the run, note the resolution and refresh rate you need, and buy for those two numbers. Everything else is a convenience feature.
