These are the only known issues so far but again no one seems to care since this is the fastest selling monitor in all of time for this site.
-PWM flickering when not at 100% brightness (no one seems to be effected by it or can notice it. I leave my screen at 100% brightness anyway it's not really too bright IMO)
-Strange artifact issues where colors bleed off horizontally or vertically on the screen (most noticeable in grays, only reproducible on office/web use and not games/movies. I posted about this on page 24. People seem to not care, don't notice it enough, or calibrate their monitors to not show or minimize this effect)
-Screen drops to 30hz sometimes when monitor goes to sleep (can minimize this by adjusting computer/screen power cycles, turn the monitor off then back on, ect.)
had mine a few days now so tested it out for my needs.
got one pc in the displayport 3840x2160 @60hz, this pc is for general family use, office, paint email, web browsing, movies etc etc.
server is on the vga port
and games pc is in the hdmi until I can sort a mini dp to dp cable 1920 x 1080 @60hz for now.
got the brightness at 85% as 100% is way too much for me, I have not seen any flickering, I will be honest and say no bleed issues at all under any condition, it also resumes from sleep without going to 30hz.
although..
it does return from sleep and for some strange reason the taskbar is off screen (just need to tap win key for it to return) and it makes open windows smaller but this could be a windows thing as I removed 3 monitors and replaced with this one.
all in all I am super happy.
desktop scaling is set
@100% and ie scaling @125%, no eye strain and I do wear glasses, and I do mean bottle bottums as well lol.
not using the monitors sound but if I did I would complain it needs a dedicated volume switch, a quick input button would also be nice but if you install smartcontrol from the included cd on each device all is good.
a remote would have been nice.
oh, the inputs on the underneath would have been better, just me as I suspect others prefer them as they are.
if you are still on the fence, get off now and get one ordered.
not going to give a 10/10 as improvements mentioned could easily have been sorted with a little people testing from phillips but 10/10 for the display for my needs and 9/10 overall.
I have tried coloured bands and black on white and overlapping windows, I just cant get any faults with my settings.
30hz is pants, either use display port or stick to 1080.
thank you.
wakadoo.
