Hexus posted a review on the iiyama ProLite GE2788HS-B2
A quote from the article:
FreeSync support on a 27in panel at £170. The quality of any hardware is directly related to price. Take monitors for example. Those wanting super-high-refresh screens with ultra resolutions and some form of adaptive pacing technology have to pay a healthy premium. It's inevitable there's a paucity of impressive screens for the entry-level market, but that doesn't mean that significant value can't still be had.iiyama ProLite GE2788HS-B2 Review @ Hexus
Dubbed the Black Hawk, long-standing monitor firm iiyama has gaming-optimised screens that don't break the bank. The GE2788HS is a case in point, touting a 27in form factor, TN panel, 75Hz refresh rate and a quoted 1ms response time via overdrive. Keeping costs in check is a full-HD screen (1,920x1,080), rather than a lusher resolution, and you get all this from around £160.
Interestingly, our sample came with an AMD FreeSync sticker and logo attached to the box and panel. There are in fact two models of the GE2788HS screen, designated as -B1 and -B2, with the latter having limited FreeSync support baked in. AMD would like you to think there's no extra cost involved for the adaptive-framerate technology, though retailers are charging an extra tenner for the review -B2.
