Exact model: 34GX900A-B
240Hz WOLED with a close 800R curve
The LG 34GX900A-B combines 3440 × 1440 at 240Hz with a pronounced 800R curve. It has speakers and USB-C video at 65W, but no KVM for switching shared peripherals. Check your viewing distance and laptop power requirement before choosing this curved desk setup.
Exact model: AW3425DW
240Hz on a gentler 1800R curve
The Alienware AW3425DW keeps the 240Hz refresh but changes to a glossy QD-OLED panel and gentler 1800R curve. HDMI and DisplayPort handle video. Its USB-C connection does not accept a laptop picture, and there are no built-in speakers or KVM.
Exact model: UM.CXXAA.X01
800R curve with 90W and KVM
The Predator X34 Xbmiiphuzx pairs 240Hz and an 800R curve with 90W USB-C video and a KVM. Speakers are built in too. It suits a laptop and gaming PC sharing the same wide screen, provided the strong curve fits your desk and viewing distance.
Exact model: AW3423DWF
165Hz ultrawide without laptop docking
The Alienware AW3423DWF runs native 3440 × 1440 at 165Hz, below the 240Hz leaders here. Its 1800R curve is gentler than the 800R alternatives. There is no USB-C video or KVM, so a laptop needs HDMI or DisplayPort and separate peripheral switching.
Exact model: XG34WCDG
175Hz with KVM, light USB-C power
The ROG Strix OLED XG34WCDG provides a 1800R 34-inch view at 175Hz. Its USB-C input can take a laptop image and the KVM shares peripherals, but 15W charging leaves most laptops on their own power supply. Built-in speakers are absent.
