There is nothing you can do with a display that's unrecognized by the system.  Notebooks have embedded code in the firmware (EDID) that identifies the panel to the system. The correct panel is shown below -- it's an OEM part. [URL] Unfortunately, if you add the cost of two panels you've probably exceeded the value of the system -- you may also want to compare the cost of a newer, replacement system.  Complete and working, they're worth less than $100.  
Last week I upgraded the LCD panel to upgrade the existing 1366x768 that was already installed on my system, first try the screen had a yellow tint all over and the panel reported Unknown Panel with a max resolution of 1600x900, later I found out that the ribbon cable I had was incompatible with the higher resolution, so I purchased the right one "VGHHX" and installed it correctly, I booted the laptop and the colors were fine, but while starting, something looked off on the Dell logo as it was very slightly egg-shaped, within windows the display looked fine, after I found that max res is 1600x900, and the display appears as "ThinkPad LCD Display", before buying I checked every parameter and reference to match the ones of panels installed by dell (revision, ID, etc) the only thing that differs is the brand which is "AU Optronics" instead of the Samsung installed by Dell. I was told my GPU (HD Graph 4000) could handle that panel, tried almost everything possible (forcing resolution with external apps, full CMOS reset, reseating connectors to no avail, I'm currently with a custom scale off 115% as 125 is too big and the recommended 100% is too small, and of course, the panel is a 1080p one, and I can confirm it by taking a macro picture, and you can see the pixels unused. as it is AliExpress there is absolutely no way to get the display returned and no one knows where I will be able to get a proper one Below two pictures of the "native" resolution [IMAGE] [IMAGE]
