The image seems to be GPU scaled and skewed/distorted horribly, as soon as I set it above 100hz (so, 1080p above 100hz just doesnt display, lower res 101hz displays but skewed it seems to be a LVDS limit of 240mhz pixel clock in play here?) as shown here:Laptop panels normally don't have scalers and can't display lower resolutions without GPU scaling, so you can't use a lower resolution to get a higher refresh rate. I don't think any sort of adapter would help because you will still be limited by whatever you can get at the native resolution. You might be able to use a lower vertical resolution like 1920x540 to get 200 Hz, but the image will be repeated until it fills the screen. This tip is actually amazing! It worked! It actually displays somewhat properly (its split right at the middle, as it should! I'm curious though, if I'd salvage this panel outside for desktop use, would I be able to go above LVDS limits? And use NVidia's GPU scaling and adjust image accordingly? Or perhaps some LVDS to VGA and manually adjust image like on a CRT? Thank you very much for the tip btw!! I basically have a backlight strobed laptop right now at 200hz lol |
