Seeking the ultimate 17.3" display upgrade and fixing EMI issues

Hello again! I'm in the middle of a 'clean and extreme' restoration of my HP Pavilion dv7 (HM65/Sandy Bridge). After upgrading the CPU and RAM, I want to tackle the visual experience.

Currently, I’m looking for the best possible 17.3-inch panel compatible with this laptop. I know I’m limited by the 40-pin LVDS interface, but I want to find the absolute 'top tier' in terms of color accuracy (sRGB/NTSC coverage) and viewing angles (IPS/AHVA). Does anyone know of a high-end panel (perhaps from a DreamColor or Precision workstation) that is a drop-in replacement for the dv7?

Additionally, I have a strange EMI/Grounding issue: when running on battery, touching the trackpad causes visual artifacts or 'warping' on the screen. I suspect the display flex cable is picking up interference. Would shielding the flex cable with conductive copper tape and grounding it to the chassis be the definitive fix for this?

Thanks for your expert advice!
