How these monitors differ
Alienware 27-Inch 4K Dual-Resolution Gaming Monitor
The Alienware AW2725QF replaces the ViewSonic’s small portable form factor with a 27-inch desktop display. It weighs 4.75 pounds and measures 24.1 inches wide, making it unsuitable for travel. However, it offers a dual-resolution feature that switches between 4K UHD and FHD. This allows you to choose between sharp detail or higher frame rates. It includes G-SYNC sync technology and an 180Hz refresh rate, which the ViewSonic does not provide. You should pick this if you need a dedicated gaming monitor with flexible resolution options rather than a mobile screen.
ASUS 32-Inch 4K Dual-Mode OLED Monitor
The ASUS ROG PG32UCDP is a 32-inch 4K OLED monitor designed for large desks. It weighs 16.1 pounds, so it is not portable like the 1.5-pound ViewSonic. This model features a 240Hz refresh rate and G-SYNC support, catering to competitive gamers who need speed. It also supports dual-mode functionality, allowing you to switch resolutions. While it shares the OLED panel type with the ViewSonic, it sacrifices portability for a larger viewing area and significantly higher refresh rates. Choose this if you want a premium desktop gaming experience with high-end OLED longevity.
LG 27GS93QE 27" QHD OLED
The LG 27GS93QE is a 27-inch 1440p OLED monitor, differing from the ViewSonic’s 4K resolution and 15.6-inch size. It weighs 14.8 pounds and measures 10.2 inches in depth, making it a substantial desktop unit. It offers a 240Hz refresh rate with both FreeSync and G-SYNC compatibility. This monitor provides faster response times and higher refresh rates than the ViewSonic. You should select this alternative if you prioritize high-speed 1440p gaming performance over 4K resolution and do not need a lightweight, portable display for travel.
Alienware 27-Inch 4K 240Hz QD-OLED Monitor
The Alienware AW2725Q is a 27-inch 4K QD-OLED monitor that weighs 15 pounds. It is a desktop monitor, not a portable device like the ViewSonic. This model features a 240Hz refresh rate, which is much faster than the standard portable screen. It uses QD-OLED technology for vibrant colors and deep contrast. You should choose this if you want a compact 27-inch desktop monitor with high visual fidelity and fast refresh rates. It sacrifices the portability of the ViewSonic for a larger screen and superior gaming performance.
ASUS ROG 32-Inch Glossy 4K OLED Monitor
The ASUS ROG XG32UCWMG is a 32-inch 4K OLED monitor with a glossy finish. It weighs 16.1 pounds and measures 28.1 inches wide, making it a large desktop unit. It features a 240Hz refresh rate and G-SYNC support. Unlike the portable ViewSonic, this monitor is designed for stationary use. It offers a larger screen size and higher refresh rates for competitive gaming. You should pick this if you want a high-end OLED desktop monitor with a glossy panel and do not need the lightweight, travel-friendly design of the ViewSonic.
KOORUI 32-Inch 4K 240Hz OLED Gaming Monitor
The KOORUI S3241XO is a 32-inch 4K 240Hz OLED monitor that weighs 25.7 pounds. It is a large desktop monitor, quite different from the 1.5-pound ViewSonic portable screen. This model provides a 240Hz refresh rate and OLED panel technology. It is suited for gamers who have ample desk space and want a large, high-performance display. You should choose this alternative if you prioritize screen size and high refresh rates for competitive gaming and content creation over portability and lightweight design.

The KOORUI S3241XO also matches this high refresh rate, providing fluid performance for competitive gamers who prioritize speed over portability.
Is there a portable option similar to the ViewSonic VX1655?
The ViewSonic VX1655-4K-OLED is the only portable monitor in this list. All other alternatives are desktop monitors designed for stationary use. They weigh significantly more, ranging from 4.75 pounds to 25.7 pounds, and measure over 20 inches in width. These are not suitable for travel or mobile work setups.
Which monitor supports both G-SYNC and FreeSync?
The LG 27GS93QE supports both G-SYNC and FreeSync technologies. This compatibility ensures smooth gameplay without screen tearing regardless of whether you use an NVIDIA or AMD graphics card. Other monitors like the ASUS ROG PG32UCDP and Alienware AW2725Q support G-SYNC but do not list FreeSync in their specifications.
What is the largest screen size available in these alternatives?
The largest screens are 32 inches, found in the ASUS ROG PG32UCDP, ASUS ROG XG32UCWMG, and KOORUI S3241XO. These models provide a much larger viewing area than the 15.6-inch ViewSonic.

The Alienware AW2725QF offers a unique dual-resolution feature. It allows you to switch between 4K UHD and Full HD modes. This flexibility lets you prioritize image clarity for casual gaming or boost frame rates for competitive play.

This makes it ideal for players who prefer the balance between detail and speed on a standard 27-inch desktop screen rather than 4K or smaller displays.
