X-( I think manufacturers set monitors to maximum at the factory so they will look good for display purposes in well lit shops during business/daylight hours. Vince	Vince (406)

It is the transition from very bright screen areas to the relatively dark that causes your eyestrain, and if set correctly in subdued light only a minor tweaks of contrast and brighness should be necessary to compensate for ambient light . You should work in a well lit area too, as the constant compensation by your irises to cope with transitions in overall brightness will cause eyestrain every time . That is why people have always been advised that they should not watch television in the dark, focussing on a small area of constantly changing brighness is a real problem . It is not the same in the movies because you focus on a larger area but some people still find it a strain . It may be that the various other adjustments you have made have created additional issues because there is no way a monitor set up correctly on a greyscale step with black level first then contrast second will ever produce an over-driven image . Correctly set, it should be comfortable to look at even in a dark room . Did the right-hand (white) bar look glary when you did that set up? If so, then incorrect video card settings or gamma adjustments may be perpetuating the problem . Can you put your old monitor back and see how that looks now? You could compare its image on the greysacle steps to the Philips results and see what, if any, difference is present . Like boot problems after multiple concurrent upgrade activities, you sometimes need to roll all the way back to the original state then come forward one step at a time to identify where the problem kicks in . I would certainly set the monitor back 100% to its factory defaults, undo any changes you have made to your computer then start again . The only other possibility is that you have an undiagnosed eye problem that was not troubled by your previous setup but can't handle the improved image of the new monitor .

254786	2004-07-25 12:47:00	Well thanks to all who replied. :) It's looking okay at the moment. I've got it at 0% brightness, 80% contrast. I feel that any lower dulls the colours too much. Let me show you a photo (sal.neoburn.net) again. It's not as dulled out as that, that's just a bad camera. I'm finding it a little easier on the eyes today though, left eye seems to have come right, perhaps I was just tired? I bet Philips have a list of the correct settings for this monitor, so I might ring them up tomorrow. Or post around trying to find someone with the same one to compare settings.	kiki (762)
254787	2004-07-25 20:50:00	That actually looks about right kiki. I am really surprised at the 0% brightness though, and now I woder if there is something wrong with the monitor setup ex-factory though that is very unlikely. Did you revert to monitor defaults and all other original settings before your final attempts? You could still be driving the monitor with a distorted brightness/contrast profile You could also try the different colour temperature settings (9300K and 6500K) to see if one suits you better than the other.

254788	2004-07-26 03:56:00	Yeah the brightness doesn't do anything really, just whites the screen out. The contrast makes a big difference though. I rung the Philips help desk. They were pretty useless as their response was: "It's just user preference really, tone it down to what you feel comfortable with" :| I'm saying it's either too bright/glary and hurts my eyes or it's too low and dark. I wanted some specific settings that were properly set up at the right level. Doesn't look like they have any. :| I also have other issues with the settings like the shape to appear properly on the monitor, that's a real pain to set up because they have two controls for it, but one mucks up the other so when making adjustments it's a real dog. Also the text isn't as clear as it could be, so the convergence needs to be tweaked a little. I would just prefer if they had someone that could come round and set it up properly because clearly it's not done from the factory. Apparently they are going to get someone to ring me back... :|	kiki (762)
254789	2004-07-26 05:59:00	Convergence errors show up as colour fringing kiki, so go back to the test pattern website and check on the white crosshatch on black background, and the black and white chequerboard for any colour fringing, especially at the sides and top of the screen, and even more so in the corners . No colour fringing means no convergence errors and your text issues will be due to some other effect . Other than focus, I can't think what that would be right now, though again, drivers could influence results . Can you let us know if you have taken everything back to defaults/original during this process? If not, you could still have drive issues left over from your earlier attempts to solve the problem . The white-out with brightness increase certainly sounds weird, with it set to zero you should be able to get all the greyscale steps to be black across the first third of the screen . Cheers Billy 8-{)	Billy T (70)
254790	2004-07-26 06:42:00	Ok the convergence is set up correctly as close as it can get. Just some of the text was fuzzy at the bottom so I was thinking that might be to blame, but no. Everything has been taken back to defaults. It's actually a clean install of Windows (on Friday) and fresh Catalyst 4.7 drivers with settings at defaults. Haven't touched any settings there. The monitor itself has been reset quite a few times. > The white-out with brightness increase certainly sounds weird, with it set to zero you should be able to get all the greyscale steps to be black across the first third of the screen. Not a chance of that happening. To get that happening I have to have brightness at 0% and contrast at about 9% contrast. I'm now wondering about the colour pre-sets. There is 9300K for general use (what I've been using so far) 6500K for image management 5500K for photo retouch sRGB User Preset 9300K is sort-of where it hurts my eyes the most. White as anything. 6500K makes the colours sort of reddish and would take some getting used to 5500K is duller/reddish again sRGB (what is this?) is not too bad on the eyes. It's set at 50% brightness, 100% contrast straight off and is quite similiar to 9300K but not as intense. I'm going to put my old monitor next to this one and compare some things.	kiki (762)
254791	2004-07-26 07:46:00	Here's (sal.neoburn.net) a comparison with my old monitor and the new one.	kiki (762)
254792	2004-07-26 09:44:00	Definitely need to take Goddies advice and get some shades in front of your eyeballs kiki, ouch! sRGB - Red, Blue, Green, but you knew that. Is there a specific colour scheme for you monitor in the monitor properties? You'll find sRGB, AdobeRGB (& varients) Sony, Hitachi, Philips (hopefully), etc. Could be worth having a play.
