DisplayPort 1.4 to HDMI 2.1 Adapter 8K with HDR (DP 1.4 to HDMI 2.1) Display Port to HDMI Adapter 4k 120Hz up to 8K 60Hz with HDR Support for RTX 4090, RX 6900, Gaming PC, and More

Excellent product, plug & play operation for my setup and enables the 4K resolutions as standard, no custom configurations required.I purchased the DisplayPort 1.2 to HDMI 2.0a Active adapter to see if it performed better than the older DisplayPort to HDMI Passive adapter I had on hand with a recently purchased 50" flat panel. While the DP-HDMI passive adapter allowed me to display 3840x2160 resolution, I had to create a custom resolution for the NVIDIA GPU. After each reboot, and often after unlocking the screen saver, the custom setting and passive adapter combination would disable the 4K monitor and revert to the base 1920x1080 resolution, requiring multiple time consuming steps to re-enable the 4K monitor. I deemed the custom resolution configuration as the root cause of the instability since using a 40" 4K monitor with the same DP 1.2 port did not result in the same challenges.To satisfy my curiosity I purchased the Uptab adapter, fully expecting that the results would be the same as with the passive adapter.First I tested the Uptab DisplayPort 1.2 to HDMI 2.0a Active adapter with the 40" Seiki SM40UMP that I have been using with a single DP 1.2 connection @ 4K resolution, swapping the DP 1.2 cable with the adapter and a Redmere 18+ Gbps HDMI cable. As expected, the Seiki immediately switched to HDMI and resumed displaying 4K @ 30Hz*.I powered down, switched monitors and connected the Redmere HDMI cable to the 50" monitor using one of the two 4K@60Hz rated ports. After starting back up I was pleasantly surprised when the computer immediately recognized the 50" monitor as with 3840x2160 resolution, requiring no custom resolution configuration. Even more surprising, is that the Uptab DisplayPort 1.2 to HDMI 2.0a Active adapter exposed an undocumented *second* 4K resolution of 4096x2160 @ 24 Hz on the 50" monitor panel! Of course, I tested the 4096x2160 "true 4K" resolution and it works without issue --- Easter Egg in a monitor!Regardless, I switched back to the 3840x2160 resolution to continue testing the stability of the configuration over the next several days. Using the 4096x2160 resolution added a variable and if instability issues resurfaced, would leave me wondering if the root cause was the adapter/monitor combination or the 4096/adapter/monitor combination.My configuration is:Dell Latitude E6520 i7-2720HQM with Intel HD 3000 IGU**NVIDIA NVS 4200M GPU with 512 MB dedicated video memory**Samsung 1TB 850 EVO SSD; 2TB Seagate ST2000LM00716 GB DDR3 1866 Mhz ramDell PR02X E-Port II Plus Docking Station (supplying the 2x DisplayPort/DVI-D ports)- screen shots attached*My current computer configuration will not support 4K@60Hz from a single DP 1.2 port, therefore I cannot test the full HDMI 2.0a 60Hz capabilities of the adapter.**Before anyone points out the fact that the Intel HD 3000 and NVIDIA NVS 4200M GPUs have a documented maximum resolution of 2560x1600, you are absolutely correct --- and I was planning to purchase two 27" 2560x1440 monitors to replace the two 27" 1920x1200 monitors that were failing after 8 years of constant use based on the Dell and Intel documentation. I already had the 50" monitor and decided to see how it would look at the 2560x1440 resolution which led to the discovery that the E6520+Docking Station combination would drive a 4K resolution from a single DP port.Just as Dell's documentation states that the E6520 can only support 8 GB of 1333 MHz ram, it is a well known fact that Dell usually understates the full capacity of the on-board chipset. I've been running 16 GB of 1866 MHz DDR3 ram (2x8 GB DDR3 SODIMM) since mid-2013 without issue and have been watching the prices of the 32 GB 1600 MHz DDR3 SODIMM kits(2x16 GB DDR3 SODIMM) for the past year to see if I can access the full capacity of the Intel chipset in the notebook.

These thing's are like a mine field to navigate, as the vast majority of them simply lie about their capabilities... Knowing that the vast majority of their customers are likely only dealing with 1080p signals, maybe some at 1440p... and a few with 4k @30... Yet they boldly claim that the device can deal out 4k @ 60hz... which again, the vast majority cannot do at all. This one will try, as you'll get an initial image, but it will then go off, then on, then off, then on... as it simply does not have the throughput for all of that data. Try to use it with an Oculus, and basically nothing. The headset will be detected with the computer expecting it to work, but all you'll get is a black screen inside... Maybe a faint hint of an image attempting to begin, but then back to black. I tried it with a Lenovo Thinkpad @ 4k 60, same results... Same with 3 HP laptops, a Dell, and a Toshiba as well... It will work @ 4k 58Hz... but not 59 or above... and I'm guessing that the closer you are to 60, the more likely you will drop a ton of frames in a major dump every now and then... So 4k 30hz is the MOST I'd say this thing can handle. So it will work for Bluray players, DVD, HD set top boxes, etc... but don't attempt to use it on a high res PC setup for ANY reasons... It is not suited for this AT ALL... despite being clearly labeled in all meaningful ways and places as such. It's all lies.The device is likely quite capable in some regards, lower HD resolutions specifically... But that isn't what I bought it for, it isn't advertised as being limited in such a way.... and as such, for my needs and given it's item description, I feel 1 star is actually quite generous.... as it is a $30 item which does absolutely NOTHING in this case.... nothing at all. Other than add a ton of time to resolving this issue.

i have only been using this product for a few hours now but allows my 2080ti to send a 120hz 12 bit rgb signal to my new 144hz tv. i honestly wonder if some of the problems the other people are talking about is due to a bad hdmi cable. i made sure my cable has the premuim certified badge on it from the hdmi certification organiztion. i've tried cod:mw, cod:mw3, and battlefield 1 so far and it has performed exactly as advertised. there are other product that claim to do the same thing and i wonder if they are the same product but with a different name on them. however, i never tested them, just this one. and this one works flawlessly! if things change then i will try to update this review.UPDATE 1: after much trying of different setups, i have found that there will be a slight degradation in audio quality with this connection compared to hdmi 2.0 or 2.1. u will mainly notice the subwoofer doesn't hit as hard if u have one connected. there will also be more limited options in your pc sound settings(if u know how to access them). honestly, the improved refresh rate and color depth this adds means that the sound degradation is a sacrficie i am willing to make.UPDATE 2: i exhanged that hisense tv for a smasung one and i am having problems with it. i honestly don't blame this device because samsung has problems displaying all kinds of hdmi signals that other cheaper tv brands display flawlessly with no trouble. kinda ridiculous to have this kind of trouble out of a premuim tv brand in 2024. anyway, if u need this product to connect to a samsung tv then i do not recommend it yet. any other tv will probably be fine.UPDATE 3: i sent the samsung back to costco and got a lg. the device works perfectly with it! samsung is just crap! so, unless u have a samsung tv, i highly recommend this product to get 4k@120fps from your gpu that does not have a hdmi 2.1 port.
