The SamsungOLEDpanel
Igor asked me to take a closer look at the built-in display. Gigabyte is using an OLED panel from Samsung, which was clear to me after the spectral analysis, because you don’t see this dedicated expression of red, green and blue on a WOLED from LG. The peak is at 461 nm in the blue light spectrum. This also means that a classic RGB layout is most likely used here. A QD-OLED spectral analysis looks somewhat different.

Now we have clarified the topic. The Samsung panel comes with a resolution of 3840 x 2400 in 16:10 format (WQUXGA = Wide Quad Ultra Extended Graphics Array) and a maximum refresh rate of 60 Hz. As the panel is only 16 inches in size, this results in a whopping 283 PPI, making the picture really razor-sharp. Personally, I would prefer a resolution of 2560 x 1600 and 144 Hz, but that’s just my opinion. We will now see what else the OLED panel can do.
Pixel-Response-Times
Basically, the panel is really OLED-fast. But something is wrong here. The response time from RGB 0 (black) to gray 32 to white 255 takes an entire refresh cycle including the actual response time. If you take the outliers out of the equation, then the average response time is 0.5 ms. Unfortunately, I can’t answer why there are such outliers here. I have forwarded all my findings to Gigabyte – but have not yet received any feedback in this regard.
As is typical for OLEDs, there is no overshoot at all. After all!
It’s a bit of a shame that Gigabyte only lets 60 Hz loose on the panel here, as 144 Hz or more refresh rate could easily have been implemented with such response times.
Latencies
Since I can’t measure display lag on a laptop whose display is always connected to the IGPU, we have to live with the end-to-end latency today. This is 24.8 ms on average. If we subtract the 8.35 ms refresh lag (half refresh cycle) and the 0.5 ms pixel response time from this, we are left with 15.95 ms processing lag. Please realize that this is a mathematical derivation and not the measured truth. That would be/is a pretty high processing time. If you want to play on a laptop, you should at least take this into account: That you have quite high latencies and therefore should rather not participate in eSports events.
