PorttaHDMI Splitter 1 In 2 Out 4K 60Hz, HDMI Splitter 1x2 with auto scaling 4K 60Hz 4:4:4 4:2:2 4:2:0 to 1080P Support HDMI2.0 HDCP 2.2 HDR10 Dolby Vision 18Gbps 3D

I bought this as part of a project to mirror my Virgin Media to my kitchen TV as well as my lounge TV. As per the title, no issues with 4K video at all - no loss in quality that I could perceive. All audio from outputs seemed to be limited to stereo though - multichannel just not there any more. If you don’t need multichannel then it’s a good little box. Easy to install and powered by USB. I returned mine though as multichannel was essential for my sound setup.

The product is a decent splitter but the CEC functionality doesn't work, even when plugged in output 1 as listed in the spec table. If you care about CEC support do not get this product.

This does seem to work, connecting a 1080p monitor and a 4k projector at the same time, however there is noticeable lag in the image. Not a problem if you have delay compensation on your audio system but if not I would go for something different.

Works well as described . Using for remote placement of HDMI output from CCTV NVR 1 x 4k source in and I have 1 4k out and 1 1080p out. Then these are passed on to two separate Shu 1’s giving point to point over cat 6 to two remote monitors.Plugging and unplugging the HDMI source connector is some times required after configuration changes to re-establish the downscaling. As otherwise it can revert to 2 x 1080p.Cons, feels very light Could be made of metal rather than plastic as I guess it will get warm.

Shows same image on 2 different tvs from my sky box. Absolutely perfect.Picture quality is great and so easy to install. Definitely recommend.

It works great!

Seems to work perfectly. My setup is a single output AV Receiver with a TV and Projector (4K), both connected but not used at the same time, this works perfectly for my requirement.

The product worked fine picture wise but returned since power on and source selection hdmi cec from bt vision box blocked by splitter. Issue apparent on output 1 and output 2 and even when only one output connected.

Easy to setup and split image as expected but sound came through as stereo from Tivo v6 box and not Dolby.Without the splitter Dolby happily received by TV.

Works well, no complaints

This PORTTA 1 in 2 out HDMI splitter is a good way to use a single HDMI source and split it in to 2 HDMI compatible monitors or projectors at the same time.Included in this package is 1 HDMI 1x2 splitter, 1 USB power cable, and 1 user manual.The HDMI splitter box supports a maximum 4K@60Hz resolution and digital audio format. It is super easy to use by just connecting any HDMI devices such as PCs, laptops, Play Stations, DVD players or TV boxes to the HDMI switch box to enjoy video and audio on up to 2 monitors, TVs, or projectors.Furthermore, it supports High Dynamic Range which provides more detail in bright highlights and dark shadow areas as well as full 3D video format.Overall, I got this for in my office and it works great and is a fair price.

Thanks to these I can now have my PC image appear on both a monitor and the large 50" television with no loss of signal via the very long cable which carries the signal. Absolutely miraculous.

It was so easy to use and to set up. Its small and compact. Its very good value for money and works well with ny tv. The picture quality is really good too

I've not used the down-scaling feature, but it seems like a great idea. This is the first 4k splitter that I have found that works well.

Excellent quality and value for money. Instantly connects to devices and holds signal/communication well. Seems well made and set to last.
