This is a mid-tier monitor of the ultrasharp series and thus is coming with a standard display screen of 27 inches which is the most frequent size prevalent throughout the market owing to its affordable price tag and bigger screen size comparative to 20 inches or beyond computer screens.

To keep the U27 model as a very cost-effective gadget, the manufacturers have launched it with an FHD Display of 1920 X 2160 pixels which is like the standard size is the most common resolution type that the users are prone to have either due to their desires or more likely due to their budget limits.

AOC is a primarily new addition to the horizon of monitor dealers and manufacturers and this latest star is shining so bright that there is not a single chance to ignore its presences and for this reason, AOC products are always included among the list of best products if not the topmost but a worthwhile difference is made by their inclusion.



The first and foremost notable feature of this product is its 28-inch screen size which is a rarer display unlike the 25 or 27 inches model and thus a 28-inch screen could make a valuable difference by not moving out of the budget range and provide a slightly bigger display.

Its 4K display is not the only thing behind its color appeal as this thrilling cinematic view is an interplay of many factors of which resolution is a foremost one but not the only one. A significant role here is that of the color gamut. This enriched color gamut has the standard spectrum of 99% sRGB coverage and this is complimented by an average brightness level of 300 nits which is the mediocre spec neither very high nor very low and thus will be efficient under low ambient light conditions.

The only downside of this product is its TN panel or Twisted Neumatic Panel which is not the best one in the market and doesn’t produce a very accurate display which an in-plane switching panel would have produced. This is not an ordinary flaw to overlook and therefore due care should be given before its purchase.

One possible benefit of this TN panel is its fast refresh rate which is not possible by an IPS panel and thus this TN panel is a good addition for those who want to pursue a gaming screen.


This 28-inch screen with 20M colors and an enriched color gamut is a great device coming at 4K resolution and an AMD Free-sync technology incorporating a twisted pneumatic panel to give a swift gaming action.
