139 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other LED, QLED and OLED TVs plus TV mounts, streaming media players, antennas, cables and satellite gear we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
['The AV Access 4KSP12-S handles one HDMI input and sends it to two outputs simultaneously at 4K 60Hz. It has 3 HDMI ports total, meaning one input and two outputs, and is marketed specifically for 4K use. At $45.99 it sits in the mid-range for 4K-capable splitters.', 'AV Access is a brand that targets the prosumer and light commercial AV segment. The 4KSP12-S label confirms 4K and 60Hz support, which is a meaningful upgrade over basic HD splitters for anyone running a 4K source. The extra cost over entry-level units reflects the active circuitry needed to drive two displays at this resolution.', 'The 4.0-star average from 139 reviews is honest. It is not a great rating, but the split between enthusiastic buyers who got clean 4K output and frustrated buyers who encountered HDCP or refresh rate issues is common in this product class. If your source content is not copy-protected, satisfaction rates in this category tend to be higher.']
Pros
- Confirmed 4K at 60Hz support for both outputs simultaneously
- 3 HDMI ports in a clean 1-in-2-out configuration
- AV Access brand has AV infrastructure credibility
- Good option when you specifically need dual 4K 60Hz displays
Cons
- 4.0-star average from 139 reviews leaves room for doubt
- Priced at $45.99, noticeably higher than 1080p-only alternatives
- HDCP 2.2 compatibility issues are common across 4K splitters and may affect this unit
- No weight or dimension specs available
Performance notes
3 HDMI ports (1 in, 2 out). The product listing confirms 4K at 60Hz capability. No HDR, HDCP version, or audio format specs are listed in available data. Verify HDCP 2.2 compatibility if your source outputs protected 4K content.
What buyers say
139 reviews at 4.0 stars suggests a mixed but broadly positive experience. A meaningful minority ran into issues, which is typical for 4K splitters where HDCP and source compatibility play a larger role in satisfaction than with HD-only units.

Frequently asked questions
Does the AV Access 4KSP12-S support HDCP 2.2 for 4K protected content?
HDCP 2.2 support is not explicitly confirmed in the available spec data. If you plan to split a 4K stream from a Blu-ray player or cable box with HDCP 2.2 protection, verify HDCP compatibility in the current product listing before purchasing, as this is a common point of failure in 4K splitters.
Can both connected displays run at 4K 60Hz at the same time?
The 4KSP12-S is marketed as a 4K 60Hz 1-in-2-out splitter, so both outputs are designed to carry the 4K 60Hz signal simultaneously. Performance can depend on the cables used and the displays' individual HDMI input capabilities, so use high-speed HDMI cables rated for 4K on both output runs.
What is the difference between an HDMI splitter and an HDMI switch?
A splitter sends one source to multiple displays at the same time. A switch does the opposite, letting you connect multiple sources and choose which one feeds a single display. The 4KSP12-S is a splitter, so it mirrors one source to two screens. You cannot use it to choose between different input devices.
