The biggest win? They fully support VRR—and all three arrived preloaded with the 7.02.120_forVRR firmware. I had downloaded the firmware ahead of time expecting to flash them manually, but Windows immediately showed a VRR notification for each one. I verified with the Cable Matters firmware utility that all three adapters already had the correct version installed. The tool is simple and well-designed, so even if I’d needed to update them, it would’ve been easy. I’m running them at 2160p120 HDR RGB 10-bit, and they also handle YCC 4:4:4 perfectly. Since DisplayPort 1.4 is bandwidth-limited, it’s great to see the adapter properly passing through DSC (Display Stream Compression) from the 5080 to the 42" LG C2 without any glitches or image degradation. I’ve paired each adapter with Zeskit 48Gbps HDMI cables, which I highly recommend—this ensures stable bandwidth for 4K120 HDR with RGB 10-bit and VRR without signal drops or handshake issues. Over the past few days of testing, they've been rock solid—no flickering, no handshake delays, and no stability issues through reboots, resolution changes, or long sessions. HDR signal passthrough works flawlessly, with accurate color, proper contrast levels, and clean gradients—no banding or chroma issues observed. These adapters also run cool and feel well-built, with a compact and flexible design that makes them easy to route even in tighter setups without crowding nearby ports. Now that I know these work reliably, I’m planning to expand to a triple OLED setup using three 42" LG C4 TVs as monitors. These adapters are perfect for unlocking full-feature HDMI outputs on NVIDIA cards that typically only offer a single HDMI port—now I can run four displays at full 4K120 HDR with RGB 10-bit and VRR. Can’t recommend these enough. Review: Buy this one - It works just as well as the native HDMI port on my 50 series card, provides 4K 144hz with HDR and VRR to a TV no problem. Tried a cheaper brand first and it couldn't do it. ## Features - Uni-Directional DisplayPort to HDMI: Step into the future of HDMI with the 8K DisplayPort to HDMI 2.1 adapter.

It supports fixed refresh rates up to 8K@60Hz, 4K@120Hz, or 4K@240Hz on compatible GPUs and displays. **Q: What should I do if I don’t get the expected resolution or refresh rate?** A: Make sure your GPU supports DP 1.4 with DSC, your display supports the resolution/refresh rate, and your drivers are updated. Use a certified HDMI 2.1 cable. For help, search “Cable Matters 102101/102103 Troubleshooting Instructions.” **Q: Does this adapter work with gaming consoles like PS5 or Xbox?** A: No. It is designed for DisplayPort-equipped GPUs only and is not compatible with PS5, Xbox, or other HDMI source devices. **Q: Why do I see flickering or color distortion?** A: This is often caused by signal loss from long or poor-quality HDMI cables. Use a shorter or certified HDMI 2.1 cable, or lower the resolution/refresh rate. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Flawless VRR and 4K120 HDR on LG OLED—Now Planning Triple Monitor Setup *by A***S on July 4, 2025* I bought three of these Cable Matters DisplayPort 1.4 to HDMI 2.1 adapters to drive my LG OLED TVs as monitors from an RTX 5080, and they’ve been absolutely flawless.

Tried a cheaper brand first and it couldn't do it. ### ⭐⭐⭐⭐⭐ The only Item on the market to support VRR *by A***R on August 2, 2026* The only Item on the market to support VRR. Works well with Samsung oled and non-oled 4k 120hz+ tvs. Worked with old RTX2080, RTX4090, RTX5080. Some older models of this might need a firmware update to get VRR to work. Also another use case is that most GPUS only come with 1 hdmi port. ## Frequently Bought Together - Cable Matters 8K DisplayPort 1.4 to HDMI 2.1 Adapter with 4K 240Hz / 8K 60Hz, Unidirectional DisplayPort to HDMI 2.1 Cable Adapter, Supports RTX4080, RX7900, Not Work with PS5, Black - [Ultra High Speed HDMI Certified] Cable Matters 2-Pack 48Gbps 8K HDMI Cable 6.6 ft / 2m with 8K@120Hz, 4K@240Hz and HDR Support for PS5, Xbox Series X/S, RTX3080/3090, RX 6800/6900, Apple TV, and More --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/355292804-cable-matters-8k-unidirectional-displayport-1-4-to-hdmi-2](https://www.desertcart.lk/products/355292804-cable-matters-8k-unidirectional-displayport-1-4-to-hdmi-2) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-08-14*
