Is it 250 Hz at 1080p? With what settings exactly did you manage to run it at 250 Hz?
I don't have any settings like this. Does it use YCbCr422 automatically when you go over some bandwidth?
I managed to make it work alright at 262 Hz(DisplayPort and DVI-D with ToastyX's pixel clock patcher) without frameskipping using these settings:
Yes. I'm really not sure how. I'm using a DisplayPort cable and NVIDIA graphics card. What could different to your setup is I'm using Zowie V008 firmware and Zowie XL display driver (BENQ display driver makes no difference though). Is that what allows me to go to 540MHz, or is it something else? I really don't know.
I haven't tested higher than 165hz because 6 BPC looks like total garbage. Might be ok in some FPS games (you get the same issue with 125hz with a VT 1497-VT 1502 tweak (range due to certain VT's frameskipping), due to pixel clock > 359.99 mhz. Blur reduction does work however, although the crosstalk sucks.loopy750 wrote: ↑14 Oct 2020, 13:34Yes. I'm really not sure how. I'm using a DisplayPort cable and NVIDIA graphics card.

These are my settings at 1080p using a DisplayPort cable, pushed to the limit (540MHz?)

Just noticed you're using an AMD card. I assume that has something to do with it... maybe someone else can confirm?
I keep reading about 6 BPC and 8 BPC but it looks exactly the same at 144 Hz and 222 Hz. Here are photos:Falkentyne wrote: ↑17 Oct 2020, 16:51I haven't tested higher than 165hz because 6 BPC looks like total garbage.
Yes, works just fine at 222(1920x1080) and 264 Hz(1600x900) for me:
Didn't experience anything like that yet.Falkentyne wrote: ↑17 Oct 2020, 16:51I would honestly like to try 220hz with blur reduction enabled, but I have a feeling MBR won't work at all, or trying to use it will either cause the monitor to power cycle trip or no backlight.
The 6 bpc problem can't be seen here.Kulagin wrote: ↑21 Oct 2020, 14:33I keep reading about 6 BPC and 8 BPC but it looks exactly the same at 144 Hz and 222 Hz. Here are photos:Falkentyne wrote: ↑17 Oct 2020, 16:51I haven't tested higher than 165hz because 6 BPC looks like total garbage.
They look exactly the same on camera and for my eyes.
Though, it does show 8 bpc at 144 Hz and 6 bpc at 222 Hz:
When I started reading about that it looks bad, I was expecting 6-bit RGB, something like this:
But it looks just fine as you can see on the photos above.
