Technical Specifications
- All ports support a high refresh rate of 240Hz for both HDMI and DisplayPort! Both HDMI and DisplayPort can handle a maximum refresh rate of 240Hz, allowing for up to 240 frames per second. This is four times faster than a typical 60Hz display and about 1.6 times faster than a 144Hz gaming monitor, providing smooth and beautiful visuals.
- Equipped with 'AdaptiveSync' technology! This gaming monitor features 'AdaptiveSync' technology, which allows for variable refresh rates. Supporting up to 240Hz, it reduces tearing and stuttering, enabling a comfortable gaming experience.
- Vibrant visuals from any angle! The monitor uses an HFS panel with a wide viewing angle of 178° both vertically and horizontally. There is minimal change in color and contrast based on viewing position or angle, ensuring clear visuals from any perspective.
- Achieves a response time of 1ms (GTG) with overdrive function! This monitor uses a fast response ADS panel. By setting the 'Dynamic OD' function to 'Top Speed', the response time can be increased to a maximum of 1ms (GTG). The 'Top Speed' setting prioritizes response time, which may result in noticeable ghosting or color distortion in some visuals. For those who prioritize image quality, settings below 'Level 3' are recommended. Even at 'Level 3', the response time is still fast at 2ms (GTG), ensuring a comfortable gaming experience.
- Internal frame delay of approximately 0.03 frames (about 0.1 milliseconds)! Even with features like super-resolution and overdrive enabled, the internal delay time is about 0.03 frames (approximately 0.1 milliseconds). This is particularly effective in fast-paced games, minimizing the discrepancy between input and display. Additionally, you can check the current delay time settings displayed on the screen. (Value is for Full HD at a refresh rate of 240Hz.)

Reviews
“Gaming: I bought it on sale. I think it's good for the price. It doesn't produce sound, so I bought a separate one.”
“Recommended for beginners, but if you're looking for higher quality, consider a more expensive option: I'm satisfied with the picture quality, but if you want higher quality, you should buy a more expensive monitor. I think it's perfectly fine to use as a secondary monitor. The frame rate consistently reaches 240. The startup time is a bit long, but if you leave it in power-saving mode, it’s not too bothersome. The stand feels somewhat cheap, but it does allow for angle adjustments.”
“動作性良し。画面は小さめ、事前確認要。: 動作が滑らかで画面がよく映える。7～8時間続けてモニターを使用しても画面に影響はありませんでした。思ったより小さめなので何か代用して実際に置いて確認するのが良いですね。あとは、どのくらいの期間で画面にチラつきなどの影響が出てくるかですね。”
“Great value for money: It's a good product for the price. Excellent cost performance. Unless you're a professional gamer, you won't notice any lag.”
“Best value monitor! I was able to buy it very cheaply during a sale. It's incredible to get a 240Hz gaming monitor at this price.”
“お値段なりの品: 古いモニターからの買い替えなので当然画面はきれい。アンチフリッカーを求めていたので満足。値段を抑えるためか、ガワ（筐体や土台など）は全く高級感などなく、角度調整や、何なら組み立ての際に大雑把な人は壊してしまいそうです。ギリギリ実用に足るといったイメージ。あと画質調整などのUIが好みでなく、触る気になれませんでしたがまあ問題なし。”
“Great value for a domestic product! I bought my first gaming monitor and it's very smooth with beautiful colors. While there are certainly more expensive options available, the cost performance is excellent. The immersion and realism in FPS and action games are fantastic, and I don't feel eye strain. There are no built-in speakers, but I use headphones for gaming, so that's not an issue. Setup was easy, and I'm planning to set up a dual monitor system in the future. I'm very satisfied!”
“Recommended for those who don't particularly care about picture quality: Good cost performance, but if you want more vibrant picture quality, it's better to buy a more expensive one. I'm satisfied with this one.”
