The official Philips BDM4065UC thread

PWM gives you multiple instances of the trails, as you noted it 'split the ghosting up'. I wouldn't expect things to look quite as severe as you describe for an 18ms transition either, although the strong contrast and size of this screen could certainly make it stand out more. Do you observe this most strongly on black to white, or slightly different shades?

but not everybody is seeing the ghosting as severe as he describe and some are seeing none. so either he as a faulty monitor or each monitor have different quality..

on mine i don't have the PWM flicker

Unless it's also responsibiliy for the ghosting trails which I don't think it is, the PWM flicker is arguably the least easy to spot, as it only usually shows up if you move your eyes rapidly from one part of the screen to another - same as the colour separation effect you get with DLP projectors - because of the very 'blink and you miss it' nature of that effect, I'm almost certain quite a lot of people would never see that, on the same monitor where others do. That being said, I assumed I was one of the 'doesn't see it' people as the backlight on the Dell is the same 240Hz as the Philips and I don't see a thing - so I don't fully understand that one either...

I didn't really go looking for any of these issues - even though I was aware of some of them before purchase, I just thought 'well, some people are really picky, I'll just see how I get on' - and this is all stuff that started to bug me without me even looking for it. Each individual problem is somewhat annoying, the reason for me returning (then probably selling at this rate, since I'm not gong to be getting a refund if the warranty is through Philips) the display is because when added together, these issues add up to a thorough pain in the backside, even moreso than the graphics driver crashes MST causes.
 
Regarding the 'PWM flicker', that is something only a minority of users will see 'distinctly'. However; PWM artifacts which affect the motion clarity are very easy to spot. They cause the trails to fragment as I mentioned previously, rather than appearing as a smooth blur. It affects motion clarity, but is not really a cause of what you seem to be describing. That would be either from slow pixel responsiveness or funky pixel overdrive. It isn't beyond the rhelm of possibility that your unit has a faulty overdrive circuit. It does happen from time to time.
 
The distortion going past the borders of a static window is something I've seen a few times.

I use the sRGB mode which is 100% brightness. At lower brightness, they are still present but I probably wouldn't have spotted them.

There's one visual artifact that I can always bring up if I use a particular desktop wallpaper:-

 
Yeah, that's the sort of thing I noticed too - oddly it didn't do it all the time but I tend to use more vibrant desktop backgrounds than that these days - I certainly didn't in the past, so that would potentially have been more of an issue then than now - still begs the question - why does this happen?
 
I've done some basic testing (nothing detailed yet) and there are definitely some issues with responsiveness on the monitor. There are some transitions that are almost certainly slower than the '18ms' maximum recorded by TFT Central and there also appear to be some inversion artifacts - which could be part of the 'pixelated trails' you reported. If you move this window up and down do you see some vertical lines on the face of my avatar?

These issues will almost certainly apply to all units, but some people will not be as sensitive to them as others. Personally I'd still rate this as one of the better VA panels I've come across when it comes to responsiveness, overall, but I'll have to assess things more closely later.

Anything with any perceptible colour, if I moved up and down, I saw vertical lines. Maybe not hugely pronounced in too many cases, but they were always there to some extent - as I've hinted at, moving windows around rendered their contents almost meaningless - it was only once you'd stopped moving the window that you could easily view its contents again, which is fair enough in most cases, I don't read too many moving windows, but it's an easy benchmark for moving text in video, animation, gaming and all sorts, so if windows moving is perceptibly different from every other monitor I've owned, which it was, then it suggests an issue, to me anyway. Not even the 5 year old Lenovo laptop work have given me with a TN screen that has big viewing angle issues (to the extent I'm perpetually adjusting the screen angle to see it properly) shows any of these issues when moving windows, it's as smooth as any of my other monitors apart from the viewing angle and the much lower resolution.

I should add - one positive note with regard to some earlier comments I believe on here, I looked for backlight bleed and couldn't really find any - neither did I happen to spot any panel alignment issues. That said, as previous monitor has neither of those issues either, it's more a neutral note :D - the 3008WFP did have noticeable backlight bleed, and so does my old 20" TN Samsung, but I only tend to notice moderate bleed in TV/film - in games and the desktop I never tend to see it as the screen's rarely all black in the relevant place. For that reason plus better blacks, the UP3214Q was a marked improvement over the 3008WFP, resolution and quarter the power consumption aside.

i just tried that, i don't see any vertical lines on the face of your avatar

settings im using are

Picture Format : wide screen
Brightness: 100%
Contrast: 58%
Sharpness: 50%
Smart Response: Off
Smart Contrast: Off
Gamma 2.2
Pixel Orbiting: On
Overscan: Off
PIP/PBP Mode: Off

Color: user

DisplayPort 1.2

calibrated it via phillips software

@ samuelmorris If u know much about monitors u would know TN panels are much faster than VA and IPS

this monitor does have a slight motion blur but most monitors/tvs do... my 46" tv which as a motion filter at 200Hz i can still see a slight motion blur, but it does make it smooth having a motion filter

im not saying this monitor is perfect because it's not but for the price which should be £600 its a good 40" 4k monitor.

also this monitor wasn't really designed for gaming.

try this, open this site http://www.topcashback.co.uk/SnapAndSave/Offers then look at the black apple app store logo while moving the window up and down, i think u will see ghosting, if not then a lot of people would have faulty ones.

Tried this example - I can only notice it if I move the window very quickly. And even then it's not severe or leaving trails to such an extent that it would be noticeable.

I've been using this monitor for all kinds of gaming (FPS, RPGs etc.) and have not noticed any ghosting, blur or motion issues in any games, all running at (or just below) 60Hz.

Maybe if you're comparing this to a 120Hz model then I could understand that you might notice a difference, but for me, it's impercetible.

if thats true then 99% of people have faulty monitor (BDM4065UC)

Haha. Well this monitor certainly has 'inversion artifacts' (appears like fine vertical stripes or interlacing) and I have no doubt that is what samuelmorris was seeing with the muzzle flashes etc. on his game. But they are a fair bit fainter than the usual inversion artifacts you get on some monitors, usually 120Hz+ models.

I had previoulsy posted that this monitor is awesome. It is, in games. Tried using it for first time for some work stuff in cad, and I saw the vertical ghosting quite a lot in the cad app (Rhino). Will try to play some more with the settings, but it was quite noticable. A bit concerning tbh.

With:
Smart Image>Smart Uniformity set to Off
brightness 100
contrast 50
whitepoint 6500k
display gamma 2.2
master backlight brightness 100

...in the CAD programme I mentioned I only see the ghosting with green wireframe against a blue viewport background. If I set the viewport background to black, the ghosting is not visible. Not sure why this is...green on blue makes very faint ghosting happen.

When I set Smart Image>Smart Uniformity set to On, the ghosting reduces by 50%-ish. Almost invisible, and in practice, I don't even notice. Will play some more over next few weeks and let you know.

EDIT: I should note that in windows itself with these settings, the ghosting is next to invisible.

can someone try moving a window fast left to right and see if it slightly twists on the sides of the window

Not near my monitor but I can tell you I see what you are referring to. It's minor, and purely down to the response times I think.

Nothing that bothers me though.

I still can't fault the monitor for my uses.
 
I don't recall seeing 'twisting' per se, but that might perhaps be an artifact of the ghosting. I'd certainly see images of whatever was on the outside of the window whenever I dragged one, so if that was a certain shape then sure, I could describe what I used to see as 'twisting'.
