Hello, I had bought a Wasabi Mango 42" monitor from a Korean vendor on eBay last May and when it broke down for the second time within the first 13 weeks, neither the vendor nor Wasabi Mango provided warranty support. Fortunately, I had bought a SquareTrade warranty and they came through and reimbursed me for the full purchase amount. Orchids for SquareTrade, onions for Wasabi Mango and gnestore on eBay, and onions for eBay's useless reputation system that prevents buyers from leaving reviews after 90 days from purchase. All that does is provide an incentive for the seller to be responsive within the first 90 days and not even pretend to care once the buyer can no longer leave a negative review. Just to give you an idea of how ill-equipped Wasabi Mango must be to provide after-sale support and how little they care about their reputation, I left a scathing review of their monitor on their Facebook page and they never responded and the last time I checked some months ago, it was still there for the whole world to see. I bought this same 40" 4k Philips monitor for $699.99 at a Black Friday sale last year at BestBuy and it has been working great(*). The Wasabi Mango was an LG IPS panel. This one is a VA panel. Theoretically, the IPS panel is supposed to be "better" but I really do not have any objections to the video quality on the Philips. I have not noticed any dead pixels and the brightness is uniform throughout. It has an easy-to-use joystick control and a hard power switch. I have an ASUS GT 960 Strix video card running the nVidia binary driver on Fedora 23 driving the monitor through a DisplayPort cable. (*) Once every few months, I have to update the binary driver (it's not automatically updated) when I lose X after a kernel update. Occasionally, I'll see a flickering of a window that is not in the foreground. If I move the mouse, the flickering will disappear, which has me suspect the video driver and not the monitor. It's not frequent enough to be anything more than a minor irritant. Neither of those things are particular to this monitor. With a panel this large, I have not found any need for font-scaling. There is no way I could read text on a 28" 4k monitor without font-scaling. It would be hard to beat the price/performance of this monitor and with the weaker Canadian dollar, monitor prices have been firm. You will not see this monitor at this price very often. In short, it's a great buy if you've been thinking of upgrading to a 4k monitor. -- Regards, Clifford Ilkay + 1 647-778-8696
