LG announced its new gaming monitors at the end of last year. After our review of the 32" 32GK850, we are taking a look at the 27" 27GK750 - a 240Hz full HD screen with scanning backlight. A unique combination, which appears to not be much more expensive than the other 240Hz monitors currently on the market. It is a niche within a niche which is a niche in itself of a product, but if you happen to be a gamer on the lookout for such a specific screen, you should definitely read further.
Last year we were able to welcome a number of 240Hz gaming monitors to the market, all based on the same 24.5” panel by AU Optronics. LG are fashionably late with their (wise as it is) realisation that the market for gaming monitors deserves attention and have launched a 240Hz model. At the end of last year, we discussed the 32GK850, which is also a special 32-inch WQHD top-of-the-line model. The model that is the subject of this review also stands out thanks to its combination of resolution and screen size.
The generally accepted wisdom is that fanatical players of twitch shooters like CS: GO and Overwatch, above all want a compact screen which makes it easier to see the entire playing field at a glance. There are myths floating around about the real fanatics, who for this reason can't give up their 17” crt screens. The 24” diagonal has been embraced reluctantly once it started offering 120Hz and faster panels. In light of this, the choice of LG to make a 27” 240Hz monitor is simply remarkable. As we have seen before, the added value of 240Hz above 144Hz is not easily noticeable for most people and therefore not worth the considerable addition to the price. It's better to put it in more pixels or better panel technology.
How does anyone, then, judge if the Korean company has got it right or wrong? The 27GK750F offers 1920x1080 pixels and combines 240Hz display with a scanning backlight for anti-motion blur. This is something else, because although Benq did announce a XL2540 with “DyAc” (their own term for the anti-blur technology) we have not yet been allowed to try it out in our lab. As we have said before, at high refresh frequencies (above 120Hz) the added value of synchronisation technology is, less significant than that of anti-motion blur, although it will differ per person what is perceived as more disturbing. Whether you dislike screen tearing and jittery images, or motion blur, the 27GK750 offers a remedy for all - but not at the same time, because a scanning backlight can by definition not go hand in hand with a variable frame rate.
At the time of writing we do not yet see the 27GK750F in our Price Comparison. But LG tells us that the screen will be available from mid-February and that the recommended price will be 499 dollars. This means that the 27GK750F is indeed larger, but not much more expensive than the 24.5" competition.
