Mini LED screen, 4K & 4090 gives the sharpest brightest color and best shadow imaging I have ever owned. Tech support was great when I questioned this versus the 17" LCD screen. Glad I stayed with this beast! Well built, solid chassis, 2 SSD, Steel series RGB control, XoticPC did a great job with the assembly and upgrades. Super communication from them. Definitely a 5 Star Rating!
