Unless you're spending big, big money, buying a monitor is almost always about compromises. LG’s new 27UD88 monitor has one big selling point: its 4K resolution. But for a fairly standard 4K monitor it's pricey, with a list price of around $700 (although you can find it online for a cheaper $550). It measures just 27 inches across, is limited to 60Hz refresh, and doesn’t support HDR.
