I-O DATA DEVICE has announced a new addition to its “GigaCrysta” gaming monitor lineup: the LCD-GD251SH!
This 24.5-inch gaming display supports a smooth 120Hz refresh rate and comes with the company’s reliable Zero Bright Dot Guarantee.
Introducing the “LCD-GD251SH” Gaming Monitor
LCD-GD251SH Product PageI-O DATA DEVICE has officially unveiled the new LCD-GD251SH as part of its “GigaCrysta” brand lineup.
This entry-level model delivers Full HD resolution with a 120Hz refresh rate.
Supports a Maximum Refresh Rate of 120Hz

The LCD-GD251SH supports a maximum refresh rate of 120Hz.
Refresh rate refers to how many times per second the display redraws the image—so at 120Hz, the screen refreshes 120 times every second.
This allows for smooth and fluid visuals, even during fast-paced gameplay or motion-heavy scenes.
Since consoles like the PlayStation 5 and Xbox Series X|S also output up to 120Hz, this monitor lets you take full advantage of their performance.
A “Zero Bright Dot Guarantee” - No Toleration Even a Single Pixel

Some I-O DATA DEVICE products include a “Zero Bright Dot Guarantee.”
A bright dot is a pixel that stays lit even when the screen is dark—a type of panel defect.
If any bright dots appear within one month of purchase, I-O DATA DEVICE will replace the product free of charge under this guarantee.
It’s a tiny issue on the scale of a dust particle, and some may think, “Is it really that big of a deal…?”
But once you notice it, you can’t stop seeing it.
I-O DATA DEVICE’s Zero Bright Dot Guarantee is a strong safety net that protects users from this common monitor defect.
