Unfortunately, that's the way things are today. The companies not only launch software in beta state, but now apparently also the hardware.

It reminds me a bit of the Galaxy Note 7 fiasco. These people apparently don't learn the meaning of "quality control", identify and solve problems BEFORE launching a product to the market and not using customers as betatesters.

Anyone having any coil whine issues? When using I hear slight coil whine but that's not the worst thing.

What's more annoying is when PC is off, monitors LED starts blinking and in those intervals I keep hearing high pitch coil whine, it's so annoying.

Anyway to get rid of that pitch?

I have this monitor for a week and I have not heard any coil whine ... yet.

Make sure the power cord is securely connected to the monitor, as well as the power adapter.

The easy test is if you have a multimeter with thin terminal cables (or make them yourself with small cables) that you can insert into the output of the power adapter of the monitor, you can verify that the transformer gives you 19Vdc and 3.1A.

The more complex test, in case you have or can get an oscilloscope, you can see if there are abnormal variations in the voltage output, which could be producing that annoying noise.

Anyway, the fact that the monitor is off (assuming it stops the current to the backlight) and follow the blinking, tells me almost certainly that something is failing internally. It would be good to take the device back to the store to have it properly checked.

Please, give us feedback.

All the best.

I've had over 10 of these QC nightmares and every one did this too.
There's nothing you can do besides manually turning the monitor off before turning off your PC, or you can do it after but that's more steps.
The LED setting in the OSD brilliantly doesn't apply to the monitor while it's in sleep mode, so even if there wasn't coil whine you have to deal with a blinking blue light that can't be stopped.
The minimum time for the off timer is 1 hour that you would have to deal with coil whine, if we could make it 1 minute after being in sleep mode that would have solved this problem.
Enabling strobing enables coil whine most people notice as well.

Samsung's engineers still have their mothers dress them every morning

If someone knows of a more convenient way of stopping the monitor from entering sleep mode/blinking light and noise mode I'd like to know too.
Even if you could make the LED always on also in sleep mode I'd just cover it with some tape and the noise would be gone, but it has to default to sleep mode and default to blinking coil whine...
I hate this monitor so much

Why don't you just stick something over the LED? Either a bit of tape, or you can get these things called LED DIMS, I stick them on any offensive LED's.

I picked up one of the C24FG70s, January. No dead pixels, but after a while there's some of smearing/colour trails on high contrast images.

It's otherwise got negligible backlight bleed, and am appreciating the increased contrast over my previous TN. Though gradients are not as good as I was expecting - a marginal improvement over 6-bit TN (perhaps this is a game/compression thing? Either way I can still see stepping in the grey BG of Steam :/)

That said it's remarkable how much of a blue backlight tint there was to the old monitor's image.

Curved still weirds if me out a bit with desktop use, but it's fine in games and video.

So despite the colour trails, I'm leaning to keeping it. I just need to put more time in to Dishonored 2/Deus Ex MD (and a bit of Doom 3) to really see if it's too bothersome.

Edit: I don't have any whining noises, but the blinking LED is kinda annoying. Would be so much better if you could just turn it off without an input. Then again, I always turn my PC off at the wall when done, so its not a problem for me.

The LED isn't really a big problem just as a visual thing... but it still should have an off option, and if it did that would have also solved the coil whine problem with it.

If you hold down the joystick for a few seconds, after the signal from the PC has been lost, it should turn off. As noted in my review of the model.

Its clearly doing things to your brain, you cannot even type anymore biggrin.gif

Well I like this monitor a lot.
I know I am not the only one since there are others with my release and use it without any issues. I don't wanna fill the hate for saying it but I believe it is a good monitor. And no monitor is perfect when it comes to such specific need - 144hz.

I can see that a lot of you had various issues with it, I myself love it so far and I am not planning to return it, actually I will use it a s long as I can.
And no, I have no issues with sounds, as for the LED I don't care - I always turn everything off, it's an old habit of mine, I dislike leaving stuff plugged in when I don't plan to use it for countless hours.

Overall it's the best monitor I had, and my advice to others would be - buy directly from the manufacturer.

I did it trough a PC store like I mentioned, they are direct distributors of the monitors they sell and also managed to contact me with Samsung and explained the situation. Result - they sent me Feb 2017 model who has 0 issues not counting the one with the green wallpaper that happens only and only there (still a mystery to me), so my next one will be some Dell UltraSharp(or HDR one) as a 2nd monitor for Photoshop and some coding stuff.
