New Nec Multisync P241w causes headaches

Zitat von Arn

Hello,

I recently bought a Nec Multisync P241w CCFL lid IPS monitor, and i'm having major headaches from it.
I have read all threads in german and english that mentioned headaches / kofschmerzen / Ubelkeit etc..
and also the interesting article about backlight "flickering" http://www.prad.de/new/monitore/specials/backlight.html</a>

I've read that some people had headaches at the beginning and after a few weeks the headaches were gone...
This gave me hope . so i decided to keep the monitor , but my headaches are still present after three weeks of usage..

I have the P241 since 4 days and have absolutely no problems with it.

Could you please quote the reports, where you said that you read something about the P241 causing headaches ? Many thanks.

I couldn't find any reference. All articles that I found describe headaches in general or caused by other monitors, i.e. with LED backlight. Nothing in regards to the P241w...

The P241 uses the CCFL backlight which is also in use by the PA241, maybe for this reason to be friendly to the eyes.

I am using the monitor with a Sapphire Vapor-X Radeon HD 5770 1GB GDDR5 (connected via Display Port).

Yesterday I worked with a Laptop the whole day, connected via VGA port. Absolutely no problem and I am really very satisfied with it.

I am using mainly 2 profiles from the monitor:
a) "High Bright" with auto brightness enabled
b) in the evening I use "Full" with manual settings for brightness, usually set to 190cd/m^2

I never had such a nice TFT monitor like this one.

Hi

in regards to your questions some ideas.

I regard 100cd as too low. You should have turned on some surrounding light in the evening, so that the difference between display brightness and your room is not like "black&white" .. So in the evening I am comfortably with settings like 180-190cd.

Another thing which could be a trigger for you. When we bought a new TV, then we switched from 4:3 22" to 16:9 42". This was quite a big change. We sit 3 - 3.5m in front of this screen and the sales guy told us that some people have difficulties, because their eyes start to move as they are not capable of viewing the whole scene at once. Maybe some limitation of view angle of the eyes ... I had no headaches but it lasted 2 weeks for me until I was really comfortably looking. Bluray in 1080p was never a problem. But if you see media content (normal tv series) which have a lower reolution. Especially then it looked 1st a little bit strange.
After a month and more I got so much used to 42" that its absolutely no problem anymore.
But even then I would recommend not to do the mistake to buy a larger at this close viewing distance, as you surely do not want to cound pixels when not having full hd content

Back to monitor. I sit 71cm in front of the screen. Before I had an 19" 4:3 monitor from Medion (Aldi). It is a difference to have such a big display in front of me. But I quickly got used to. At work I am using 2 Sun Monitors, 20", 1280x1024. My viewing distance is never below this value.

Maybe it makes a difference to you when
- having the room lit (I also have a light beneath the monitor lightening the area behind the monitor, and a little of my desk)
- using in the evening maybe a higher brightness than the auto brightness is giving you
- measure the distance, maybe you are sitting too near, try 70-75cm
- try another monitor profile, I personally liked "High Bright" and "Full" more than sRGB

Most of the time I use over day with sunshine "High Bright" with "auto brightness" turned on
In the evening I am using "Full" with manual setting for brightness (~190cd).

I tried eco modes, but then I am missing a bit of contrast ...

And of course make sure with your doc, that you do not need glasses...

I am using now the sRGB profile of the monitor with automatic brightness turned on.

In windows colormanagement "systemsteuerung farbverwaltung" I choosed own settings and choosed:
"sRGB IEC61966" as standard profile. I think this ICC profile will be there after installing the driver from the nec CD.

Then really read the instructions how to setup automatic brightness.

When you are in the enhanced menue (page1) then
a) Turn on all the lights in your room and set a comfortably value (I choosed 200cd)
b) then turn off all the lights and choose a comfortably value (I choosed 90cd)

Turn on the lights again, and you will have the monitor automatically selecting the brightness to your taste.
Its now around 200 ... sometimes little more, sometimes little less +/- 10

Hope this helps !

Hi Andreas,

What are your video card setting..?
[...]

Hi Arn,

grafic card settings are default, nothing special.

When looking at extended settings (list of all supported modi), I discovered that 1280x1024 can be displayed with 75 Hertz.
Maybe try this mode to see, whether the Hz change from 60 to 75 Hz makes things better for you.

I discussed the size of monitors today with a colleague, I told him 24" inch monitor and Pivot doesnt make much sense,
as then the Monitor is very very tall ... He agreed and said better would be to take 2 smaller monitors.
One for "Landscape" and the other for Portrait (pivot).
This is nowadays no problem as you can get many graphic cards with 2 DVI ports or one DVI and one display port.
Maybe you can operate both screens then with a higher Hz value as with 1920x1200 ?! Just a thought.
