ASUS ROG Lays Claim To World's First 32" 4K OLED 240Hz Gaming Monitor
The biggest challenge of using an OLED in a situation like this is actually keeping it cool. Heat is the enemy of OLEDs, and it's overheating that causes burn-in and early death of OLED cells. ASUS says that it uses a graphene film behind the entire panel along with active cooling that intakes from the bottom and exhausts out the top to keep the ROG Swift PG32UCDM running cool despite its ability to hit 1000 nits peak brightness.
Well, maybe there's one downside. For inputs, you get HDMI 2.1 and USB Type-C, as well as DisplayPort 1.4. To actually drive this thing at 4K, 240 Hz, you're going to have to use Display Stream Compression. That's not a huge deal; DSC is almost entirely lossless. Still, likely both NVIDIA and Intel's upcoming graphics processors as well as AMD's current chips will support DisplayPort 2.1, which could handle this display without needing compression. It's the single miss on an otherwise flawless product.
That aforementioned USB Type-C port has a few other tricks up its sleeve, too. It can function as a USB hub for the USB Type-A ports on the device, and it even has a "Smart KVM" feature to swap the USB hub connection to another device. There's also picture-in-picture functionality and support for keyboard hotkeys to switch between inputs. Of course, the ROG Swift PG32UCDM also has Variable Refresh Rate support.
