That article says I can get 4K for 350. More interested in that than the 8K, anybody got a link in Europe?
This year 2 27" 4k IPSs for ~£350 each (both LGs, the first one a better model but cheaper because pre-Brexit-vote).
Prices have gone up from my POV.
In answer to your question: https://www.overclockers.co.uk/monitors/by-type/4k-ultra-hd?... -- under £300 for 24" 4k IPS. OCUK is a UK subsidiary of Caseking (de), so I'd be surprised if similar prices weren't available across Europe.
In all the above experience, I've found Acer to be very good (3 monitors, 2 excellent and 1 with pixel defects), Benq to be poor (multiple returns before I gave up and bought something cheaper) and LG to be absolutely flawless.
