+# Dell Precision 5490
+
+Linux kernel versions prior to 6.7 may not function correctly with the internal monitor, as official support was introduced in version 6.7 (https://www.phoronix.com/news/Linux-6.7-Intel-Meteor-Lake-Gfx). You can enable experimental support by adding the following parameter:
+
+```
+boot.kernelParams = [ "i915.force_probe=7d55" ];
+```
+
+However, this may lead to some screen tearing.
+
+If possible, you might benefit from a newer kernel, for example:
+```
+boot.kernelPackages = pkgs.linuxPackages_latest;
+```
+as it seems to work without any issues.
