Cable Matters4K Active Mini DisplayPort to HDMI Adapter (Active Mini DP to HDMI) Supporting Eyefinity Technology

I have, I think, a bit of an unusual set up so I'll explain that first and why I ended up buying this adaptor.My home PC has an RTX 2080, which only has a single HDMI port and many full size DP ports. The HDMI port is taken up by an Oculus Rift, and I was running an old 24" 1920x1200 60Hz monitor using an Amazon Basics DP to HDMI adaptor and an Amazon Basics 10m HDMI cable, as my PC is actually in the living room so I have more space for VR.This was all working fine... until I upgraded to a 32" 2560x1440 144Hz monitor a few months ago, where the Amazon adaptor just wouldn't work at any more than 1920x1200 60Hz, so I had to use the HDMI port instead and keep swapping cables whenever I wanted to use the Rift. The HDMI port was working fine, so it must have been something to do with the Amazon adaptor. That's now solved with a fibre DisplayPort cable, and also means I can have a dual monitor set up with my old monitor back on the Amazon adaptor and 10m HDMI cable... not that I really need it on my home PC...What has any of this got to do with a mini DP to HDMI adaptor? Well, I work from home half of the time and having two monitors is actually rather useful there. My work laptop has an HDMI 1.4 (I think) port and Mini DP port. There are plenty out of mini DP to HDMI adaptors out there, but most state a max resolution of somewhere around 1920x1200 60Hz, which appears to match my experience with the full size DP adaptor that I am using on for my home PC. I took a punt on this one as it states that it supports 4K at 60Hz, and I can happily confirm that it's working fine at 2560x1440 144Hz!There is a review claiming that this is not an active cable. I honestly have no idea if it is or isn't, but it's working fine for me. I don't think the Amazon Basics full size DP one stated the HDMI version or whether it was passive or active, so it could just be as simple as this one is HDMI 2.0 whereas the Amazon one is only 1.4, and nothing to do with passive vs active? No clue, but I'm happy!

This isn’t an ‘ACTIVE’ cable which is wanted by maybe to enable more than 2 screens detected by your computer. However this doesn’t do that it is simply an adapter fraudulently claiming to be ‘ACTIVE’ to get more purchases from consumers and at a higher price point to guarantee their sales. I want a refund not that I would normally bother with such petty amounts but as a principle of hating being conned!

Does exactly as described no issues with pitch quality or sound only wish the shape was more ergonomically designed as Square shape is quite bulky at the end

MS surface go attached via the surface dock and the ultrawide monitor would not work beyond 1920 x 1080.

Works with a Microsoft surface. Good value for money. 3 stars for durability as I don’t know yet. Looks well made

This does not work with Mac mini dp to hdmi, tried on 2 computers, says active but how?Just don’t but this if you want it to work!

Solved my external monitor need with Microsoft Surface Pro 3.

Does exactly what it says. Works a treat.
