Monitor Banding - asus ml239h
polycounter lvl 9
Hi guys,I'm having a huge problem with my monitor,so I was hoping that someone of you could help me out.
The problem is,when I have a Gradient going on,let's say for example - the black to grey gradient of the background of 3ds max 2014 Perspective View - I have this nasty banding going on,where you pretty much can tell apart each shade of gray,& you can clearly see where the shade change each 5mm .
And by the way,my Nvidia Control Panel is set to 32 bit.
Just for experiment purspose,I lowered it to 16 bit,if I do that,the same gradient of 3ds max perspective viewport now has a banding visible each 1,5 cm, & the worst thing is that they are not all shades of grey, the go like - grey-green-gray-green-gray-green-gray-green - & so on, slowly increasing the Value parameter,but stil with this fucked up added green, 1 band yes & one band not.
To better clear what am I getting here,I used the picker you have inside 3ds max to pick up the colors of this bands, in 16bit mode,this is what I got,starting from top band to bottom band:
RED :---1/3/4/4/7/7/9/9 /13/13/17/17
GREEN :2/3/4/5/6/8/9/10/12/14/16/18
BLUE :--1/3/4/4/7/7/9/9 /13/13/17/17
And here a the most fucked up thing I have discovered while I was doing this picker experiment: the picker showed me as 3/3/3 two different bands,one beign clearly more toward the green,so I am actually not seeing the numbers of red/blue/green that the picker is picking up,the screen is showing me a different image for some arcane reason,the green I am seeing on those other bands is not even 1 point of green up or down as showed by the picker,cause I can tell the bands very clearly apart from one another...
Also,let's say the green problem happen only on 16 bit mode - still,on 32 bit color I have a visible banding each 5mm,even if the picke give proper numbers for RGB,like 111/222/333/444/555 & so on...
So what my monitor is showing me,is not the real image or what the numbers says...help me to figure this out guys,I beg you

according to this, your monitor is only 6-bit, which would explain the banding. being an IPS monitor should help, but it won't get rid of it. even the dell 23xx series of IPS monitors suffer from mild banding.
edit, just re-read. what i said holds true for the gradient areas of your monitor, i'm not 100% on whether it would affect large coloured areas, but i'd guess not. email Asus and see what they say?
@almighty_gir,ok,I'll copy paste my first message of the topic & forward it to asus.
In the meantime if someone knows more about this please let me know
thanks guys
now I don't have the money to buy a new one,damn...
don't get me wrong, it's miles better than a TN panel, and the price vs performance is fantastic, but you will see a difference between the 6 and 8 bit panels.

that is an excellent website to do research and check reviews of any monitor you're going to purchase.
Funnier thing is that if I hit the button "click here to reply",after I write & send my reply I get a funny message on the asus site wich says "Sorry! The server is busy now. Please try again later!"...really?! my mail weight so much that can cause serious harm to asus servers,or maybe they are receiving milions of mails that says to fuc* themselves for the laughable customer support
Well,this is pretty much the hystorical moment when I swear not to purchase Asus hardware anymore,sorry for the outburst
i hope it all goes well and you get it sorted. maybe it is just a faulty monitor, but in all probability it's a 6bit thing.
