AV Access 1 in 2 Out UHD 4K@60Hz 1080p@120Hz HDMI 2.0 Splitter with Auto Downscaling,18Gbps Zero Latency, 1×2 4K HDMI Splitter with HDR10 and 3D, HD Lossless Audio, HDCP 2.2, Auto EDID Management

I bought these to attempt to get 4K HDR from my PC to my living room TV. I couldn't afford a more expensive HDBaseT kit (like the SEADA HBT70B) and this unit appeared to hit the sweet spot of features and price. I've tried a few scenarios and its operation is generally as expected. The LED indicators are useful as they reflect both incoming and outgoing signal presence, useful for diagnosing problems with low quality cable or cable runs which are too long and cause too much signal loss. The HDMI2 output with integrated downscaler appears to cause no observable degradation to image quality (banding or aliasing) and there's no noticeable signal lag. I've not tested with a sync signal or clap test but it looks fast enough to be used for things like theatre presentations / office AV setups - or even things like UHD and scaled HD simultaneous output from a video camera or vision mixer in a production environment. You could definitely use this unit in your output signal chain if you're a FPS gamer, the unit doesn't seem to add any meaningful latency. I've not yet been able to verify true 4:4:4 colour space and end-to-end audio bitstream pass-through, but I suspect they do work as advertised. My first tests: 1/ Taking HDCP protected output from a Sky+HD box to a primary display (4K TV) and a secondary 1080p monitor plugged into the duplicating output. I was impressed by that, as Sky+HD boxes are notorious for detecting HDCP issues and 'bluescreening' the video signal. This means the unit could be used to repeat a Sky+HD HDMI signal to multiple TVs in a house, as I had no issue sending 1080p or 1080i25 down a long run of HDMI cable. 2/ Outputting HDMI 2.0 4K HDR from a Windows 10 PC (GTX 1070) to the 4K TV worked OK, although the HDMI cable length and quality makes a big difference. With a longer run of cable (30 metre HDMI cable) I could not achieve HDR, only 4K SDR or 1080p60. I managed to get a 'sweet spot' of 4K HDR using shorter cables and positioning the unit at the midpoint, but only to a maximum of 30 Hz - that's fine for all film and TV content but frame rate in games will obviously suffer. I suspect the signal loss from my long run of cheap HDMI cable (about 30 metres) takes its toll on being able to achieve >30 Hz. I'm sure with a shorter run of HDMI, or using higher quality HDMI cables (I'm using cheap HDMI 1.3 cables with female-female adaptors along the run) - or HDMI-ethernet extenders - I would be able to do 60 Hz, 4K HDR. Without using more costly equipment and cabling you can't expect miracles, and you cannot beat physics even with super-expensive HDMI cable. (And what's the point in trying? HDBaseT is really the only option for >30 metre runs.) For my intended purpose - getting HDR UHD signals from a computer ~30 metres away to a TV, without using LAN streaming - this unit works almost exactly as I was hoping for. Used at a midpoint between the PC and TV, the unit does a great job to equalise the low SNR, poor quality signal from the PC, reclocking and boosting it sufficiently for the TV's input to recognise it. When I used a single run of 30 metre HDMI cable, the SNR was not good enough to even get full HDR, so I'm happy with the performance of these units. When connecting multiple displays, it's important to connect the highest resolution display first, so it can properly clone the monitor EDID and maximum resolution properly. The manual explains the process well.

4K and HDMI 2.0 has been around now for a while, yet for ages now I've been searching for an HDMI splitter which would allow me to duplicate a 4K 60Hz 4:4:4 signal to two 4K displays - with no compromises. I had previously purchased devices that were only capable of 4K 30Hz even though it was advertised as a 4K 60Hz device. Frustrating! Until now I had been unsuccessful, but at last I found it! My search is over. This little beauty will do exactly as advertised. It has excellent build quality and works flawlessly. It is fully compatible with HDMI 2.0b (with an 18Gbps limit) and HDCP 2.2. I have two 4K displays, but as a bonus, If you have one 4K display and one 1080p display, it will even scale down to 1080p for that display ONLY, leaving the 4K display at its native 4K and the 1080p display at its native 1080p - Excellent! Obviously high quality HDMI cables are required, otherwise you might struggle with 4K60Hz. For reference, I ordered a few Amazon Basics HDMI cables with this, and they work perfectly. Just hook it up, connect the included power supply, and it just works. Amazing device from AV Access!

I bought this to split the video and audio from my Xbox one S because my SONY STR DN1020 only oputputs 1080P. I also bought a good quality 1.4Meter HDMI2.0a cable for the job. This splitter will output 4K 60Hz to my TV but it will not output DTS HD or Dolby True HD. I thought my Xbox was being picky because it may be detecting my TV not being able to support DTS HD or Dolby True HD so I conneced my SONY BDP3700 1080P BlueRay player to the splitter and I am still not getting DTS HD or Dolby TrueHD. So I connected the new HDMI Cable from the blueRay player to my amp and the amp to my TV and I get DTS HD MA and Dolby TrueHD audio when the HDMI is going directly from the BlueRay player to my amp bypassing the splitter. I Even tried switching the output from the TV from HMDI OUT 1 to HDI 2 and the output to the amp from HDMI2 out to HDMI 1 out which made absolutely no difference. Which means that the advertising on the splitter and the manual are wrong. [UPDATE] I contacted AVAcess about my issue with the sound and their support engineer sent me a firmware that kind of fixes the problem. Now the splitter will output DTS HD Master Audio but Dolby True HD is still being output as Dolby Digital. The engineer told me that this is the only solution they have to offer. So my rating will stay at 3 stars because the advertised specs tell it outputs Dolby True HD and DTS HD which is only half true when a new firmware is flashed to it.

I purchased this splitter as my existing one would only output to both HDMI in the lowest resolution of the 2 connected TVs. This splitter claimed to be able to support both 4k and 1080p simultaneously. When I first plugged it in , it would only output to the 4k TV and nothing appeared on the 1080p TV - I contacted AV Access and they got back to me within 24 hrs with a firmware update - presumably these items sit in the warehouse at Amazon for a while and can have older firmware on them. Loaded the firmware update and bingo - we now have a 4k input passing thru to 1 4k TV and 1 1080p TV - so far so good, no dropouts - excellent product.

The video from my UHD disk player can now be viewed on a 4K display and also input to a 1080 AV receiver. The image quality for both 4K and 1080 is excellent. I have not given the product 5* as I have a problem with how the audio signals are handled. DVD audio as 5.1 surround sound is OK via an Anthem MRX receiver. However, when the audio signal from a Blu-ray disk in the UHD player is sent via the 4KSP12-S splitter / scaler to the AV receiver DTS-HD Master Audio 5.1 becomes DD 3/2 and DTS-HD Master Audio 7.1 becomes PCM 2.0 (that is stereo). I contacted AV Access asking if there was a way to allow the 4KSP12-S to handle DTS-HD sound tracks but it appears there is no solution. If your main concern is to send a UHD video signal to a 4K TV and a 1080 TV this unit is excellent. If you also want DTS-HD sound tracks then, depending on your AV equipment, it may not work. You may have more luck than me.

Worked great sending my 4K Virgin Tivo signal to my 4K TV in one room and the other output scaling it down to 1080p for the other room. Then one day I could not get a picture on either source. I could get a picture by removing cables and powering off / on devices but not consistently. Every time I wanted to watch TV it was touch and go if it would work. Have reluctantly returned and ordered a much more expensive HDFury Integral 2 hoping for better results. In the meantime I have put my old 1080p splitter and is working perfectly, but no 4K picture.

Perfect. My £15 splitter was stopping BT Sport UHD outputting in 4k, despite the cheap unit being labelled as 4k. After an evening researching this I found out it's all to do with HDCP etc. Anyway, this new splitter fixed EVERYTHING! BT box goes into Input. TV connected to HDMI output 1 is the 4K one and it works in 4K, whilst simultaneously the older HD TV on output 2 is downscaled to 1080p. Yes, this gadget DOES allow mixed output from BTTV 4K UHD depending on the max. resolution supported by the TV. Perfect for BTTV if you want 4K UHD split. Oh, and the image shows the front and the back of the unit on top of each other - it is only single height. It also comes with some little mounting brackets if you want it fixed somewhere. Brilliant.

Easy setup, used fibre optic HDMI which is pricey but it’s working over a 25 metre run absolutely fine and zero latency still. HDANYWHERE did my absolute nut in I wished I’d found this brand sooner! Literally 10/10 no qualms! Works a treat Photo added is of the 1080p tv upstairs working a dream Is even working with zero latency on arc for the Sonos soundbar downstairs One thing I will recommend if doing this turn off hdmi control on the sky q settings otherwise when you go upstairs with the Bluetooth remote which works fine it will turn the telly on downstairs but a 5 second fix no dramas now 😆👌🏼👍🏼

Ero alla ricerca di uno splitter che mi consentisse di uscire con risoluzioni diverse sui due output HDMI, per sfruttare contemporaneamente la risoluzione 4K del decoder Sky Q sulla TV e la risoluzione FullHD sul modulatore HDMI che distribuisce il segnale sulle altre TV di casa. In pratica sono riuscito ad avere la botte piena e la moglie ubriaca! Restano da verificare la resistenza e la durata nel tempo, ma di primo acchito mi ritengo soddisfatto dell'articolo, che è arrivato in tre giorni dall'Inghilterra.

The reason I bought this device was, that I purchased an Android TV box which has a 4k HDMI output. My old Sony TV was not able to handle this signal, so I am using the AV Access HDMI Splitter to downscale the signal to 720p which works perfect on my old TV. The price / value of this item is definitely worth it.

Great switch works !!

Este splitter es compatible con HDMI 2.0. Permite enviar imágenes desde dispositivos con HDCP 2.2 sin cortar la señal. Transmite también señal HD 4K. Funciona perfectamente, al contrario que otros splitters que prometen las mismas funcionalidades. Un acierto total.

Pour splitter un décodeur tv vers un video projecteur via un ampli home cinéma et directement vers une tv qui n'est pas compatible HDCP 2. Résultat parfait sans aucun problème pour l'instant.
