I am hoping the Iiyama GB3466WQSU-B1 will be a good monitor. As I said before it uses the same panel as the AOC and has essentially the same features. I note the Iiyama is HDR400 accredited and the AOC is not. Although my limited understanding of HDR accreditation is that if you really care about HDR you need a monitor with HDR600+. Only at HDR600 will you really see/benefit from HDR visuals. For our situation with a budget of £400-600 and looking at UW, then HDR600+ is not possible at the moment. Howeever, I don't know if the Iiyama engineers have made additional tweaks to get more from the panel, given it has HDR400 accreditation. Reviews doing calibration tests will reveal how good it is. The IPS Iiyama seems to be well calibrated from the factory from the very limited reviews/remarks given. Either way, I suspect we will be driven by stock availability first!
