Non-uniform colours and brightness

Hi all, first poster here.

 

Purchased a S235HL about 6 months ago, which worked brilliantly for a while.

 

Over the past couple of weeks I've noticed the left 3rd of the screen isn't as bright, or smooth as the right 2/3rds.

Tricky to explain but if I load paint and fill the entire screen with a solid colour, the colour is far from uniform across it.

 

Yellows fade to a green/blue, reds darken, greens look not too bad, and blues head toward a greeny colour.

 

Is there any kind of test/calibration I can do without returning it for repair?

I've checked the menus and there doesn't seem to be anything obvious in the form of calibration or diagnostics.

 

Also, would this be covered under warranty as technically the entire screen works with no dead pixels, it's just the colours are way off on the left side.

 

Monitor is connected via HDMI, but I've swapped it for a straight VGA connection with the same results. I've also got a 2nd monitor (17") connected via VGA that's not having any issues - this eliminates the graphics card and cables as causing the problem.

Thanks in advance Smiley Happy

    Unfortunately not very helpful as it's broken Smiley Wink

     

    [removed stack trace, etc.]

    Also, I've spoken with 2 live chat support people, both of whom were next to useless, didn't answer my questions, and could barely speak english.

     

    Not happy with calling a premium rate number either.

     

    Pretty unimpressed so far, lets see if the e-mail team are any good.

    The page I reference is not broken. 

    What page are you going to that appears to be broken?

     

    Also, how did you get to chat support if the page was not working?

    The main support page works, but when I get as far as booking it in for repair via this page : http://customercare.acer-euro.com/customercare/CaseBooking.aspx, clicking on next generates the application error.

     

    So I'm not able to book it in for repair.

    I'm not seeing an error with that page when I follow the process below:

     

    Go here: http://customercare.acer-euro.com/CustomerCare/

    From there, you can click on the first arrow for Contact Acer Service.

    This should take you to a page to select your location.

    You should be selecting United Kingdom/English.

    The next page is Do you own an Acer product?  Yes or No

    Answering Yes, takes me to the booking page with no issues.

     

    I then enter the SNID of a unit, click the magnifying glass to search for information, fill in the other fields as needed, click Next and it takes me to the next page.

    I'm getting to the case booking page, entering a serial number (no idea what a SNID is), filling out the rest and it immediately errors with the Stack Trace I posted earlier.

     

    Screeny of the case booking page filled out : http://i.share.pho.to/4bc8a898_o.png

    Screeny of the error when I click next : http://i.share.pho.to/cbe9a5fa_o.png

     

    Interestingly, I've just noticed the monitor is now showing signs of "screen burn" where I've had an image on the screen for a long time, load something else on the screen and there is a residual ghost image left behind.

    OK, thank you for following up with me, especially with the attached screenshots.

    I'll get this over to the right folks to deal with.

    Still broken, so still unable to return.

    Continuing to post that it's broken does not do anything at this point.

     

    I will post when I've verified that it is corrected.

    Right side of screen is also now failing.

     

    It's been almost a week since reporting the fault on your online form, are you any closer to a fix?

     

    I noticed that the error is complaining about invalid characters in the "Product" field... characters that are auto-populated after I enter the Serial Number.

    The invalid characters are : "58CM 23'' Wl S23HLBBMI

     

    And the error specifically refers to them

    "

    A potentially dangerous Request.Form value was detected from the client (ctl00$PageContentPlaceHolder$ProductHidden="58CM 23'' W, S235HL...")."

    I would really recommend that you call your local Acer service center and get the unit set up that way.

    It sounds like your system is only getting worse.  I'd rather get it repaired sooner than later.

    Given you only operate premium rate numbers (from a mobile), and your online services do not enable me to setup an RMA, I have now convinced my retailer to raise an RMA despite their recommendation I deal direct.

     

    I have informed them of the difficulties and lack of assistance I have received here at the Acer forums, online chat, along with zero response to enquiries made by e-mail, on your official facebook page, and your twitter account.

     

    I am quite disappointed with the support I have received so far and I imagine this will be my last Acer purchase due to the above.
