    ASUS 25" 500hz TN panel

    Don't know if it's the same kind of flicker as phones/tablets, but all the displays based on LG's panels do flicker. Not just at low brightness but at all times. Seems to be the way they refresh. Unfortunately in my case it's enough to cause eyestrain / headache within several minutes of dark...

    ASUS 25" 500hz TN panel

    I guess it depends on how you define "self-emissive", but a raster scanning display, for example Laser Phosphor Display could potentially have less burn-in risk than any OLED or μLED while retaining excellent contrast, and having inherently superior motion.

    LPD: Laser Phosphor Display - Successor to CRT?

    Hah, I never checked Ebay for this. Cool to see the actual units On the laser pico projectors they use a tilting micromirror to steer the beam in a raster pattern. It seems pretty straight-forward... I think the tricky part is using internal reflection to take up the throw distance, since the...

    LPD: Laser Phosphor Display - Successor to CRT?

    (a couple years back I posted a thread at BlurBusters about this. Posting here since I'm interested in HardForum's thoughts.) LPD is a rear projection display using a scanning laser (ultraviolet) which excites coloured phosphors on the screen - Very similar principle to CRT (which steers an...

    Interest in brand new 8K 80Hz CRT for 8000$?

    160 Hz on CRT would still have better motion clarity than any currently available LCD.

    Dell Alienware AW3423DW 34″ QD-OLED 175Hz (3440 x 1440)

    Thanks I didn't see that quote from Rtings before. Confirms my observations... Nope, I can't see it directly, but after ~15 minutes of dark room viewing I get eyestrain / headache. Here's a collage of the Pana OLED (right) at different luminance settings side by side with a CCFL LCD. Curving of...

    Dell Alienware AW3423DW 34″ QD-OLED 175Hz (3440 x 1440)

    Yes, these look like uncoated panels. The poster I was replying to was unaware of why glossy panels had a bad reputation for use in lit environments. Screens like that are the reason. AR coating leaves a "red hued variant" of the reflections, as you've said - everything is tinted with that hue...

    Dell Alienware AW3423DW 34″ QD-OLED 175Hz (3440 x 1440)

    On the Panasonic OLED that I tested which used an LG panel, flicker was always present regardless of settings - consistent with Rtings measurements of all the LG OLEDS which show a regular luminosity drop:

    Dell Alienware AW3423DW 34″ QD-OLED 175Hz (3440 x 1440)

    Early and low-end glossy screens have bright reflections. Newer and high-end screens dim the reflections significantly using an optical coating (at the expense of colour accuracy). With a diffuse surface, reflected objects are not recognizable, movements are more concealed, while contrast...

    Dell Alienware AW3423DW 34″ QD-OLED 175Hz (3440 x 1440)

    I'm getting mixed reports. Some say that the flicker only happens with g-sync / variable refresh enabled - unlike LG OLED where it's always present.

    Dell Alienware AW3423DW 34″ QD-OLED 175Hz (3440 x 1440)

    Interesting - so kind of like the phosphor layer on CRT or plasma... I wonder if the R-G-B of the subpixels is actually visible with the display OFF and looking with a magnifying glass in a lit room. Also now curious if shining a blue light from the front will activate the quantum dots.

    Excellent post. TestUFO's moving photo demo with the street map option selected is extremely useful for testing this. https://www.testufo.com/photo

    The Alienware (top) is clearly flickering. I thought it was supposed to be flicker free? https://www.certipedia.com/quality_marks/1111246519?locale=en This is the third or so clip of it I've seen where flicker is visible.

    Annoying bug with my monitor?

    OK so it seems like it's an artifact of the content - black/grey bar of the interface, not necessarily the program itself. This makes sense if it's a hardware issue, which I'm suspecting. I know that when a monitor's LCD is showing black it is applying the most power to those pixels. It seems...

    Annoying bug with my monitor?

    Interesting - so if you take a screenshot with the same window in view, paste it into paint or another image editing/viewing program, wiggle that window around, you don't see the effect?
