Worked ok under Windows 11 with my LG Ultragear+ 45" Ultrawide (5k) and Nvidia A400 gpu, but I could not get it to work under Ubuntu Linux 24.04 with the same hardware. Linux could not get any monitor EDID information with the adapter, so was stuck at low res 640x480. After many hours of trying to troubleshoot, and manually tweaking settings via modeline and other options, I finally gave up. Using under Linux is my primary need, so the adapter doesn't fill my requirement. Giving three stars as it worked as ok under Window 11.

Works fine under Windows 11, but I could not get it to work under Linux with an LG Ultragear+ 45" Ultrawide Screen (5k screen) and an Nvidia A400. Could get all resolutions, including 5k under Windows 11, but no luck with Ubuntu Linux Desktop 24.04. The adapter would not properly pass any EDID info under Linux and would leave me stuck at low res 640x480. After many hours of troubleshooting, and many permutations of trying to force specific resolutions I gave up getting it to work under Linux. For me that was the main use, was with Linux workstations, so doesn't meet my need unfortunately.

Ordered 4. One of them is DOA.

The device works quite well. Better than the Cable Matters cable or adapter.
However, I can't activate Dolby Atmos, which is understandable if it only accepts PCM.
According to the firmware update information, it only supports certain NVIDIA drivers, but it works quite well for me in the latest versions.

Working Perfect.. out of the box

great device, works a treat!

Arrived on time works well

Adapter lets my mid 2012 non retina macbook pro output 2560x1080 so its great!!

I'm using it in conjunction with my surface pro 3 docking station and HP quad HD monitor.

Sensational buy,perfect customer service. Sorted all my problems out with extra help from the buyer as well. Cannot speak more highly.

Pricey for what it is.Arrived next day (Prime). Does what it says on the tin. Takes a 4K signal from my AMD card to the TV.

Very happy to confirm this works, 3840x2160 @ 60Hz into the HDMI 2.0 port of a Philips BDM3275 monitor. W4100 FirePro graphics card, Windows 10 x64. HDMI cable is 3.5m (3m + 0.5m pigtail + gender changer).

2 months ago, randomly it started giving a purple picture. Unplug it -plug it in again solved the problem. Now does not work at all.

Works great, as described. Connected R9 280x to my new TV LG 55UF770V. Now I have my 60hz on 4K resolution.

Shocked that this worked tbh. Built a lounge pc with an old ATI 7800 which only supported 4k@30hz on hdmi but displayport couldn't connect to my TV because its HDMI only. Thought I would take the gamble and try this adapter out even though I thought its a bit pricey. Behold plugged it in and Windows 10 picked it up 4k@60hz. Very pleased.

Allows me to use my two amd 7950s hdmi 1.4, in crossfire at 60hz, on a 4k hdmi 2.0 lg tv.i can play fallout 4 at 45 fps with shadows set to medium at 4k resolution with i920 overclocked. saved me buying new video cardx2 and new cpu+mobo+memory.fingers crossed the adapter will keep working as well as it does now.

Just the job for connecting 4K tv to macbook pro..

Fast Delivery and works perfectly.

Does not appear to function as intended. When I go from my pc via mini dp 1.2 to my 4k monitor without the converter it works fine. The same when I go over the hdmi 2.0 to my tv. However when I try to use the adaptor to go from my pc to my tv via the adaptor it does not work and just flickers solid frames of color.

I only had HDMI in on my panasonic UHD TV, this adapter didn't work beyond UHD 30hz initially but with switchresx and these settings:pixel clock 594.0active H 3840 V 2160,front porch H 176 V 8,sync width H 88 V 10,back porch H 296 V 72,scan rate H 135khz V 60,I got it working from both my mac pro (2016) and my macbook pro (mid 2015) at full UHD 60hz! SO HAPPY!

Broken within 6 months, no longer displays a picture. Better off with the club3d adapters

I'm using this wit my Surface Pro 3 and a Dell U2515H monitor at 2560 x 1440 resolution and 60Hz - works perfectly.

yes does work 4k at 60hz....would and will buy from them again....also like to add.....i ordered the wrong one by mistake...(my fault they look very similar....make sure you order the right one....i wanted the display port...but somehow managed to order the mini display port one...so just be careful when ordering guys)..i sent the other one back..and a few days later received the correct one....great service...thank you..consdiring it was my mistake in first place......i am using this on a gtx 1080 ftw gpu to my 4k tv....using the display port from my gpu to the hdmi 2.0 on my tv......would also like to point out i am using high speed hdmi cables....so cant say for sure if they work on cheaper hdmi cables......but i wouldn't think so...although i picked up good ones here on amazon for a few quid...not expensive...and well made....if any needs any answers contact me on here and would be happy to help people out if they have any questions about this product......i will test this adapter on my new 4k amp when i get it in a few weeks...will update on here at that time.......to see if it works on passtru....i cant test this at the moment because my current amp cant pass tru 4k signal to tv...but imagine it will.....also it says hdmi 2.0a capable...so this should be good for hdr content to

Works as expected

Works as described 4k @60 frames per second

Guys, i am SO HAPPY! I have a hisense 43 inch 4k tv, and plugged it into my mac using a standard hdmi to minidisplyport from the apple store - it was only going to 30z and it wasnt usable - i think tried swichresx with the old apple adaptor, and i did the disable SIP and did a custom resolution and said invalid - not activated - then this amazing adaptor came in the post - and BOOM!! instantly worked!! i now have a 43inch 4k MONITOR!THANKS SO MUCH GUYS! ITS GREAT!!! - All the other engineers are jealous, so i think we will order 5 more :-)

Works as mentioned

Works great

Worked perfectly on my Mac Pro and Samsung curved 55" 4k TV, giving crystal clear 60Hz. Beautiful. It's a nice looking adapter too.I was starting to worry I'd never get 60Hz, but this worked first time. Oh, I also had to change the Samsung TV into UHD Color mode for the HDMI port.

has anybody been able to make this work for windows 10 bootcamp on an iMac 5k? I'm getting 4K at 30hz

Works very well
