Need backlight bleed fix LG UM95-P

Greetings all

I've just imported my LG UM95-P from Spain it's a beautiful display but it has some minor but very distracting backlight bleed I have less than 30 days to decide if I want to keep it, the picture bellow exaggerates the perceived backlight bleed under normal viewing conditions only the bottom left is visible and only when the screen is black:

On 100% Brightness see the distracting yellow bleed on the lower left hand corner.

As you can see on 0% Brightness there is hardly any back light bleed at all which rules out IPS glow .

Overall I'm very happy with my LG and by comparison to many LG UM95-P owners I have very little bleed but the effect when viewing a dark image a film or game (Amnesia: The Dark Descent) being a prime example is like the glow of a small campfire to the left of my peripheral vision which breaks the sense of immersion.

As these screens are well known for this issue a replacement is unlightly to solve the problem, I have attempted to fix the problem myself using Credit Card Light Bleed Fix as seen in this video:

Although it did not fix the problem nether did it worsen it pushing at the bottom left of the screen temporarily removes the light bleed, I even went so far as to try a suction cup which yet again had no effect

My last attempt will be fit a folded piece of paper in gap between the screen and the panel as in the following video 1:00 in:

Thanks for reading any feedback would be greatly appreciate

May I ask why you imported from Spain? the UK models pretty much have that issue sorted

I imported for the price less than £460 inc del depending on the exchange rate at the time from A----n.es in the UK your looking at well over £600 for the privilege, having owned a Benq XL2411T that was so bright that it hurt my eyes no matter what setting I changed, I can really appreciate a good IPS screen don't think I can ever go back to the Benq, I'm getting used to the small blemish on my LG it's just the resale value with the backlight bleed that bothers me as I intend to upgrade to a OLED+freesinc monitor when they do come out be it 2 or 4 years time.

I report success!!

Having tried and failed with fitting a folded piece of paper in the bezel fix, I reverted to using Credit card light bleed fix with a variation.

1. first move the tips of your fingers and very lightly press along the very eages of the screen and the bezel itself along the light-bleed and a little beyond it you should notice that when you hit just the right pressure point that small parts of the light-bleed will disappear under your touch these are the areas you will be targeting.

2. Some caution is advised as you must (at own risk!) slot the credit card in the bezel (The flat/smooth side against the panel avoiding any razed lettering that might damage) until a small portion of it is no longer visible and weg it against the panel in affect leveraging against the the non-visible portion of the panel, this part is uncomfortable to say the least as you'll need to be flexing the credit card along the effected area and almost to the very corner of the bezel you may hear the panel creak a little, but don't worry this is normal ((you'll need to listen to your instincts and not over do it)) as you move slowly along the light-bleed area keeping an eye out for the desired effect, it is a matter of trail and error in all I spent over two hours until I succeeded.

I wish anyone who attempts this every luck with their light-bleed fix, and inspite of all the caution given above I believe this guide to be safe to follow but as with any DIY fix your experience may vary from mine.

Crestfa11en,

glad it worked, but I wouldn't advise it as a long term fix

you can always contact the LGUK customer services and they may be able to help you sort it as they have a fix that is more in line with the warranty than that, and in theory its a European warranty so they should help
