ASRock Challenger CL25FFB 24.5" IPS Full HD 144Hz Gaming Monitor
An affordable 144Hz IPS screen for first gaming builds, school and home-office desks.
144Hz IPSFull HD 1920 × 10801ms MPRTAMD FreeSync
The ASRock Challenger CL25FFB is a 24.5-inch IPS monitor with Full HD (1920 × 1080) resolution and a 144Hz refresh rate — an entry-level gaming display that also works well as an everyday office screen. Part number 90LXA0V0-A0E0A0N.
Its IPS panel covers 99% sRGB with 178° viewing angles, 300 nits typical brightness and a 1500:1 typical contrast ratio, while AMD FreeSync smooths gameplay by matching the refresh rate to the graphics card. Response is rated at 1 ms (MPRT), and flicker-free backlighting with ASRock Low Blue Light reduces eye strain.
Inputs are one HDMI 1.4 port (up to 144Hz) and one VGA port for older PCs, with an internal power supply, a tilt-adjustable stand and 100 × 100 mm VESA holes. At 24.5 inches, Full HD looks crisper than on a 27-inch screen.
Compatibility note: There is no DisplayPort, USB, headphone output or built-in speaker — audio must come from the PC or external speakers. 144Hz works over HDMI only; the VGA input is limited to 75Hz. The stand tilts (-5° to +20°) but does not adjust in height or swivel.

Frequently Asked Questions
How do I get 144Hz on the CL25FFB?
Connect via HDMI and set 144Hz in Windows display settings and your GPU driver. The VGA input supports up to 75Hz only.
Does the CL25FFB work with a laptop that only has USB-C?
Yes, with a USB-C to HDMI cable or adapter that supports 1080p at 144Hz. The monitor has no USB-C input of its own.
Is the CL25FFB good for office work?
Yes. 24.5-inch Full HD gives comfortable text sharpness, the IPS panel keeps colours consistent, and the flicker-free backlight helps during long days. Add speakers or a headset for calls, as it has no audio output.
What is the difference between the CL25FFB and the Phantom Gaming PG27FFS1A?
The PG27FFS1A is a larger 27-inch 240Hz model with two HDMI 2.1 inputs, DisplayPort, speakers and swivel; the CL25FFB is the simpler, cheaper 144Hz option with HDMI and VGA.
Singular Expert Insight
