Display Mounting without Screw Tabs (Precision 7520)


M4980
 Share

Recommended Posts

I have had a 1440p LG LP156QHG panel from the Alienware X15 R1/R2 laying around for a while and decided I would like to install it into my Precision 7520. I currently have the FHD model so I'm going to need a 40-pin eDP cable, the display doesn't have mounting tabs so i will need to install it using another method

 

edit: got some 1mm double sided foam mounting tape, will post results

 

Inside of the top case for reference:

Managed to get the display tested and installed

Works fine in the 7520 with brightness control too

I haven't tested above 144Hz, I don't think the HD 630 optimus supports it at this resolution

I used two layers of this foam tape:

PE Foam Double-Sided Adhesive Tape -Outdoor and Indoor Super Strong Foam Seal Strip for Automotive Mounting,Weatherproof Tape for Car,LED Light Strip, Office and Home Decoration, Photo Fram(0.47”X33FT : Amazon.co.uk: DIY & Tools

 

It's 12mm so 24mm total, but I should have used another layer as the display edges aren't making contact with the bezel as they should

Be aware that this tape is an absolute nightmare to remove if you make a mistake, not even sure if I'll be able to lift the display out to fix this
