Chosen Solution
Ok so I had a problem with my laptop. The brightness control cannot dim or brighten the screen. This happened after I replaced my broken screen, I have an Asus FX504 that had a 60hz IPS panel, I bought a 120hz IPS panel in ebay that is compatible same pins same screen size and same resolution. It works fine except for the brightness control. I can’t control it with the function keys I cannot control it using the Control panel. So I don’t know what is going on. Is there something I can do? One more thing Windows only sees it as Integrated Monitor instead of the monitor’s brand and model. Please help me out.
Hi, Seems like the display panel is not fully compatible with the laptop motherboard. Here’s an image showing the part numbers for the displays for 3 different Asus FX504 models, -GD, -GE and -GM There is only one 120Hz display available and all three models use the same one. If you search online for 18010-15605500 this will give you the 120Hz display that will work with the laptop
(click on image) Note: The “unavailable” shown for the displays only means that the supplier didn’t have any and not that they aren’t available elsewhere either. To work out why the display that you have now doesn’t fully work you would need to have the datasheet for the display and also the schematic for the motherboard and compare the pinout wiring for the video cable connection on both to make sure that they are exactly the same i.e. all the wires at the motherboard video cable connector are designated the same on the display video cable connector To find the datasheet for the display you have now, search for (insert make and model number of display) datasheet. The make and model number is usually on the back of the panel. To find the motherboard schematics search for (insert make and model number of motherboard) schematics. The make and model number is printed on the motherboard itself. It may be easier to return the display as not compatible and find the correct one for your laptop
