LG UltraGear OLED 27GX790A now available but with lesser DisplayPort 2.1 than originally thought
The curse of poor DisplayPort 2.1 strikes again. For context, it took HP two months before it admitted that the Omen Transcend 32 did not support Ultra-High Bit Rate 20 (UHBR20), a standard which delivers 80 Gbit/s transfer speeds (DP80) over one DisplayPort 2.1 connection. Now, LG represents are doing the same with the UltraGear OLED 27GX790A, which debuted earlier this month.
To recap, there were suggestions that the UltraGear OLED 27GX790A shipped with an 80 Gbit/s capable DisplayPort 2.1 connection like the Gigabyte Aorus FO32U2P. However, LG has since backtracked by clarifying that the monitor utilises the lesser UHBR13.5 standard instead. Thus, the UltraGear OLED 27GX790A delivers approximately 54 Gbit/s over DisplayPort 2.1.
Consequently, the monitor lacks the bandwidth required to run natively at its native 1440p resolution and 480 Hz refresh rate. As a result, it must employ Display Stream Compression (DSC) to reach this frame rate and resolution combination, just like the ROG Swift OLED PG27AQDP and Inzone M10S (curr. $999.99 on Amazon).
In short, there will be a degree of information loss when gaming at 1440p and 480 Hz. Incidentally, LG has now opened pre-orders for the monitor, which remains exclusive to the US at the time of writing. At the time of writing, LG hopes to begin shipping pre-orders the week of December 30; please see the company's website for more information.
