LG to Introduce 34-inch IPS 21:9 UltraWide (Model UM95) monitor

Of course when I return the unit I will probably find out it's an issue with the monitor itself and by "Calibrator" it meant the monitor calibrator, still I can';t enable the calibrator in the monitor OSD, it stays off and if I try to turn it on it tells me to run the software and that will enable it.

Apologies if you have already tried this but to get the calibration to work i needed the monitors built in USB hub connected to my PC via a USB type A to B which wasn't included with the monitor. I then already had the driver for my Spyder4 installed as i was using it with the DataColor software so i just uninstalled their calibration software so the driver was still installed for the calibration device.

I then plugged the Spyder4 into one of the USB ports on the back on the monitor, installed the TrueColourFinder software off the included disc that came with the monitor, once the software had found the monitor and initilized i started the TrueColourFinder software and the Spyder4 was in the drop down list for available calibrators. I was then able to start calibration. Having the monitor connected to your PC with a USB type A to B is crucial i think.

No need to apologise, I appreciate any ideas anyone has.

I've been in IT tech support for over 20 years now so I'm fairly technical although the last 10 have been networking/server related and Android OS programming so I am unfortunately quite behind on desktop hardware (watercooling aside).

Never had to calibrate a monitor before but I can certainly see the benefit.

My monitor is connected via A-B cable to the pc, I plug my Colormunki sensor directly into the monitor's USB and the pc picks it up and automatically installs it as a "HID-compliant device" no conflicts which I am fairly certain is correct.

It will not accept any driver updates so it seems to be the best driver.

I'm starting to think the error is between True Color Finder and the monitor, not True Color Finder and the Sensor as when I plug the sensor in True Color Finder does see it and adds it to the selectable list of sensor as "i1Display Pro" which as mrk and others stated it most likely is.

The more I think about it the more I feel there is nothing wrong with the sensor or True Color Finder and that it should work, I'll put the refund on hold whilst I troubleshoot a while longer.

True Color Finder software is version 3.1.3 that came with the monitor, seems to be the latest available as LG only seems to offer download for older versions for older monitors.

Hi All,

Been following this thread for a while due to the reports of bleeding issues, I've snapped a picture (pitch black room about 2 metres away) of my 34UM95 to get some opinions:



The most noticeable area is in the bottom left in the form of an orange tinge / glow, which is only ever noticeable in very dark scenes in film/games. It does seem to mostly go away when I look head on at where the glow/bleed is located. Visible glow/bleed gets worse the closer I move towards the screen. Everyday usage of my PC it's not visible or noticeable at all. I'm a little on the fence as to if I should do anything about it?

Thats IPS glow part of the technology. I have a brand new 34" UM65 mine is not that bad when you move your head it goes away its barely noticeable even on pure black screens.

If you tilt the monitor upwards it equalises it a little.

I am connected via Display Port you cannot adjust the Black level its auto set to High.
 
Mine could be IPS glow but it's hard to say since this is the first IPS panel I have owned though if it is then frankly it seems almost like the cons of IPS far outweight the pros as only light images and video will display correctly. I can move around and it does not seem to get better, worst of all whilst lessened it seems to affect the blacks in the centre of the screen, I can't seem to get a decent black.

I'm hoping calibration will help but thus far I've not been able to get my monitor, software or sensor to work together so hard to say.

Snapped som pics on my poor quality Iphone 4 camera.

The two are quite different in colour as I have been messing with brightness and temps to try and allievate the problems, the red tinge is in cenima preset and the other picture is with settings reset and brightness lowered to 15.

Turned the backlighting off as my camera picks up some wicked glare off the wall behind, the problem is just as bad with quite a lot of ambient light in the room but almost impossible to take a picture of.

I've managed to improve it but now I feel things are maybe a touch too dark and possibly dull colours.

Need to get calibration working but I'm failing miserably, starting to wonder if maybe the hardware LUT inside the monitor is busted.
 
I've tried to replicate your photos in order to compair, first shot is the full screen shot around 1 metre away pointing at the centre:



Head on at the left portion of the screen:



Head on at the right portion of the screen:



I took the photos with my blinds closed with any other light sources in the room turned off and I must admit that the bleeding/glow looks pretty bad in those conditions (worse than what a camera shows). Where as in daylight or with the lights on it doesn't look anywhere near as bad to the point where it isn't noticeable unless you go looking for it.

Yours looks like a smaller area but just as pronounced, tbh it feels like yours is unacceptable.

I'm starting to think I've drastically improved mine to the point whereby I might be ok with it, but frankly the colours and contrast look a little dull and my 27" Viewsonic from 7 years ago (which was pretty cheap) is outstripping it by far.

Need to fix this calibration issue but I'm almost out of options, my next step is to format my primary SSD, install windows 7 and true color finder only, nothing else then test.

If it still fails install windows updates, test again and then I'll have to contact LG to see if the monitor is faulty (hardware LUT shot maybe?).

You think I should get it fixed/replaced?

Wish I could answer that question, I'm almost out of 28 days on my monitor so I should have made up my mind but I'm still unsure as to whether or not my LG 34UM95 has a problem.

My plan at present is to...

  1. Calibrate the monitor (using hardware calibration).
  2. Re-assess the problem and whether or not i bothers me.
  3. If it does bother me I will contact LG and seek a replacement hopefully from a new batch.

Hopefully by then they have addressed the problem and will be more open to assisting their customers,

Frankly if they don't they've lost a customer for life and I'll make damn sure my friends, colleagues and business customers are aware of their poor support and issues with build quality.

On the brighter side I'm positive I've reached figured out my calibration issue.

The LG True Color Finder software lists supported models, I know everyone states this is the same sensor as the i1Display Pro but I'm not convinced it is and their list is very specific.

Supported Models

X-rite Inc
◾ColorMunki photo
Version 1.1.1◾ColorMunki design
Version 1.1.1◾i1DISPLAY Pro(i1Display3)
Version 0.4.7.2

No mention of the cheaper Colormunki Display, the part numbers and model numbers on my sensor are all specific to the Colormunki Display it seems.

I simply think it's an unsupported model that is being mistaken by the LG software for the i1Display Pro.

I have asked Colormunki and hope to get an answer on whether the sensor is the same or not, LG email support is unavailable right now (quite pathetic really, can't even get a web form right).
