Now we get to the fun part: how fast is the FO27Q2? To find out, I compared its test results to five other 240 Hz QHD OLEDs, Dough’s Spectrum Black 27, Pixio’s PX277 OLED MAX, AOC’s AG276QZD2, View Sonic’s XG272-2K and the Asus PG27AQDP which runs at 480 Hz. The results were surprising, to say the least.

For the PG27AQDP to refresh the screen in 2ms is no surprise; it’s running at twice the rate of the others. What is amazing are the input lag results. The FO27Q2 is officially the most responsive gaming monitor I’ve ever tested. 13ms of total lag is a result I had to verify with more test runs. After shooting 15 videos instead of the usual five, I was convinced. This thing is other-worldly. Of course, there is no motion blur, but that is true of any 240 Hz OLED. But the only monitor even close is the 480 Hz Asus.

Test Takeaway: If low input lag is your priority, it doesn’t get lower than the FO27Q2. It’s blindingly quick and it beats my previous record holder, the 480 Hz Asus PG27AQDP by 2ms. Based on numbers, no faster or more responsive computer monitor currently exists.

Viewing Angles

I’ve already mentioned OLED consistency as a major reason to buy one, and the viewing angle photo shows this. I’ve only observed the most subtle differences between OLEDs screens in this test. QD models often show a slight red tint at 45 degrees to the sides and the FO27Q2 has that if you look closely enough. In actual content, there is no visual difference. This is excellent performance.

Screen Uniformity

OLED panels are also consistently uniform in tone. They always ace my test with numbers well under 10%, the visual threshold, and often below 5% like the FO27Q2. My sample looked perfect in every situation with every kind of test pattern and content.

    The first review page contains "stunning" 6 times. Give it a rest, else it causes me to doubt your sincerity somewhat.

    I find it strange this review was posted after the Envia 27M2N8500 review. Primarily my issue with this is that the Envia has lower input lag than the Auros FO27Q2, which you note in its review. I think this could be confusing to readers and should be noted somewhere.

    I bought this monitor a couple of weeks ago. I didn´t see mentioned that there is a firmware and driver update that enables DisplayHDR True Black 1000, actually reaches 1040nits in mine. On the reviewer´s defense, I can´t find a better adjective than stunning on OLEDs screens. The only drawback on this particular monitor is that it is glossy and really reflects any ambient light and blacks can come as purple if it isn´t in a dark room.

    TBH I don´t know.. info is mixed.. Some say the Q2 240Hz is gen2 and the Q3 360Hz is gen3.. They have the same OLED Care technology and both are Samsung panels so I´m not sure.
