DisplayPort 1.4 to HDMI 2.1 8K 60Hz HDR Active Adapter

Yep

4k 120hz 4:4:4 HDR

First let me say that the product is working perfectly but there is a backstory to this.

I originally bought this in October of 2021 and was disappointed that it was only passing a 4:2:0 signal from my 6900xt to my LG C1 and had intended to return it (even received an RMA). I changed my mind on the hope that it was a firmware issue that would be resolved as a support e-mail had said the issue may be with LG OLEDs at that time.

Well, I don't know which firmware did it but I decided to try this again tonight on a whim and it works great.

Excellent Product did exactly what i wanted

Bought two LG monitor and anted a simple effective way to connect both. UPtab did the job effectively so I did not need the bulky docking station. Will buy or recommend that other buys also. PS NO drivers needed

Works better than expected, pleasing results

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.

DisplayPort 1.4 to HDMI 2.1 8K 60Hz HDR Active Adapter

Plugged it in and it worked. Piece of cake...

I am a professional software developer and I need a large desktop. I currently utilize a 40" Samsung curved UHD TV with two additional 24" monitors in portrait mode (one on the left and one on the right of the Samsung.) My graphics card is an EVGA 960 with 4GB. This card has 3 DisplayPort outputs and 1 HDMI output. Previously I was using the HDMI output of the graphics card to drive the Samsung TV. This worked well (UHD at 60 Hz) but I was unhappy with the arrangement because the computer would always post to one of the smaller screens when booting up.This adapter allows me to use my Samsung TV as the primary display with one of the DisplayPort outputs. (4K UHD at 60 Hz). See the screenshot I have attached to this review.Note: As an experiment I tried several inputs on the TV. One of the ports is labelled "HDMI 1 / DVI". This input appears to provide more performance than the other HDMI inputs on the TV. For example, this input allows the video card to provide 4K (with RGB, YCbCR 4:4:4, YCbCR 4:2:2 or YCbCR 4:2:0) and 32-bit color with 8 bpc. The other inputs on the TV do not appear support all of the output color formats. BUT... I personally do not LIKE the way the HDMI 1 / DVI input "looks". I can detect digital "shadows" adjacent to lines and fonts. And the display seems "harsh".

I never write reviews but I felt like this deserved it. 8k 60 Hz instantly from my 1660 Super GPU

I recently got an 8k TV for programming and productivity (HIGHLY RECOMMEND)... My 1660 Super on my work PC only has HDMI 2.0b, which only supports 8k 30Hz, which is painful to use.1660 Super also has DP1.4a ports, which carry much higher bandwidth. I was highly skeptical this would work as this was only one of two converters I could find on Amazon to do DP1.4a to HDMI 2.1.I plugged it in, and after restarting my PC it instantly worked with my TV. Native 8k resolution at 60 Hz. Incredible. AND I was surprised to find it allowed for a higher colorspace as well due to the higher bandwidth, so the picture overall looks better than it did before, on top of getting 60 Hz instead of 30 Hz.Thanks for a great product, does exactly what it says it would do.
