## Questions & Answers

**Q: Is this adapter bidirectional?**
A: No. This adapter only works from DisplayPort (computer/GPU) to HDMI (monitor/TV). It does not convert HDMI sources (like PS5/Xbox) to DisplayPort displays.

**Q: Does this adapter support VRR, G-Sync, or FreeSync?**
A: No. It does not support VRR, G-Sync, or FreeSync. 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.

### ⭐⭐⭐⭐⭐ 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. 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.

### ⭐⭐⭐⭐⭐ Works Good
*by L***N on September 15, 2025*

Did exactly what I needed it to do. No drop in video quality from what I can tell. Easy to use, works completely fine, decent quality especially for the money.

### ⭐⭐⭐⭐ Solid Adapter with Great Features, but Specs Can Be Misleading
*by J***. on August 9, 2025*

I picked up this Cable Matters 8K DisplayPort 1.4 to HDMI 2.1 adapter to connect my DisplayPort-equipped GPU to my HDMI 2.1 TV, and for the most part, it works as advertised. Build quality is excellent — the braided cable feels durable, the molded strain relief should help it last, and the LED connection indicator is a nice touch. It supports high resolutions and refresh rates, HDR, and surround sound, making it a great option for gaming or 4K/8K media.However, there’s one important technical caveat that isn’t clearly explained in the product specs. While the adapter claims HDMI 2.1 support (8K@60Hz, 4K@120/240Hz), it’s still limited by the DisplayPort 1.4 bandwidth on the source side. That means those higher refresh rates and resolutions often rely on heavy DSC (Display Stream Compression), which can noticeably reduce visual quality, especially in fast-moving content. If you expect full uncompressed HDMI 2.1 performance, this limitation may be disappointing.For reference, my monitor is a Asus 42" 120Hz 4K OLED with HDR and full 10-bit color. On a display of this caliber, DSC would be a gross degradation of quality, introducing artifacts and compression that completely defeat the purpose of such premium image fidelity. Because of that, I will never enable DSC and expect uncompressed signal quality whenever possible.For most users connecting a modern GPU to a high-refresh-rate monitor or TV, it’s still a solid and reliable adapter — just go in knowing that the bottleneck is DisplayPort 1.4, not HDMI 2.1.
