Linus Tech Tips: The video discusses the features and benefits of the ASUS PG27UCDM, a 4K 240Hz QD-OLED monitor, highlighting its high refresh rate, pixel density, and lack of display stream compression.
Linus Tech Tips - *My* PC is not good enough for this Monitor…
The ASUS PG27UCDM monitor offers a 4K resolution with a 240Hz refresh rate, providing exceptional motion clarity and pixel density. This monitor is the first of its kind to support ultra-high bit rate (UHBR) without display stream compression, delivering up to 80 Gbps bandwidth. It features OLED technology, which enhances HDR capabilities with deep blacks and high brightness, and includes a Neo proximity sensor to prevent image retention by automatically switching to a black screen when not in use. The monitor supports variable refresh rate with G-Sync and claims to reduce flicker by 20% with its anti-flicker technology. However, to fully utilize its capabilities, a high-end GPU like the upcoming RTX 5090 is necessary, as current GPUs like the RTX 4090 cannot drive it at full potential. The monitor also includes multiple input options, including dual HDMI, USB-C with power delivery, and DisplayPort 2.1.

1. 🔍 Exploring Monitor Innovations: 4K 240Hz vs 2K 480Hz
- ASUS introduced the PG27UCDM, the world's first 4K 240Hz 27-inch QD LED display, notable for its lack of display stream compression limitations.
- The monitor supports Ultra High Bit Rate 2 (UHBR2), delivering up to 80 Gbit per second, which ensures high frame rates and detailed visuals.
- This innovation caters to users needing either fast refresh rates for motion clarity or high pixel density for sharp visuals, appealing to both gamers and professionals seeking superior display performance.
- The 4K 240Hz display is ideal for those prioritizing high-resolution visuals, while the 2K 480Hz option suits users focused on achieving maximum refresh rates for smoother motion.
2. 🎮 Upgrading to 4K 240Hz: A Worthy Trade-off
- Transitioning to a 240Hz 4K display involves a trade-off between refresh rate and resolution, moving from 480Hz to enhanced 4K clarity.
- The 4K resolution provides over twice the resolution, offering enhanced visual clarity without the need for compression.
- OLED technology in the new display boosts HDR capabilities, delivering superior contrast with deep blacks and high peak brightness.
- OLED displays are praised for their accurate colors and excellent motion clarity, significantly enhancing the visual experience.
- The upgrade eliminates the need to choose between VA, IPS, or TN panels, each of which previously had significant drawbacks, thereby simplifying the decision-making process.
- The 240Hz refresh rate, while lower than 480Hz, still supports smooth gaming performance, balancing the benefits of high refresh rates with 4K resolution benefits.

- Device supports OLED anti-flicker and HDR formats, with options like HDR10 and Dolby Vision for better viewing.
- Practical use case includes adjusting sensor settings to prevent accidental activation by pets, like cats, enhancing user control.
7. 🎮 Future-Proofing with Display Stream Compression
- The integration of Display Stream Compression can lead to significant improvements in power management, as it may allow monitors to handle power states independently, reducing reliance on operating systems like Windows.
- This technology can help prevent issues where monitors receive a signal but display a dark image, causing unnecessary power consumption from the backlight staying on.
- Future-proofing display technology with such compression methods could enhance energy efficiency and extend the lifespan of display hardware by optimizing power usage.
8. 💡 Anticipating Next-Gen GPU and Display Advancements
- Display Stream Compression (DSC) technology is impressively effective, even when not operating at full potential, suggesting significant future capabilities in display technology.
- There is speculation about achieving refresh rates of 600 HZ or 1,000 HZ using DSC, indicating a potential leap in graphics and display performance.
- Despite previous reluctance due to pricing, there is an openness to investing in the upcoming 50 Series GPUs, highlighting a shift in consumer willingness to adopt new technology.
- The 480 HZ 1440p monitor from Asus has been recognized for its remarkable performance, emphasizing advancements in high refresh rate display technology.
