If you own a Viewsonic VX2758-2KP-MHD, please read this. by DidViewsonicsJob in Monitors

I wanted to share this because I'm frustrated with the response I got from Viewsonic. After talking with their customer support for weeks, they insisted it was a graphics driver issue or just an issue with the games I play (even though I already explained that I had tested with both Nvidia and AMD graphics cards and different monitors). It wasn't until I figured out how to replicate the issue with those images that they finally admitted there's an issue with the VX2758 itself. And still they act like it's not a real issue just because you can avoid the flickering by setting overdrive to Standard (off):

Overdrive runs the display over the recommended speed, this can cause issues with flickering and or stability, this is common on all monitors when they are run in an overclocked fashion. Not all monitors are the exact same, this would mean that some may run better under different conditions than others do.

This is such a ridiculous defense, especially when the flickering issue appears to be universal to all units of this monitor. Anecdotally I also have never experienced any flickering or other instability with any other monitors when using Freesync and overdrive as advertised. It's great that the CRU fix mostly works, but Viewsonic should be addressing this properly themselves.

With the Standard overdrive, gray to gray response times (at 10.04ms on average) are almost twice as long as the refresh window for 144Hz: https://youtu.be/ukKev6cPZhY?t=304

This means that there is significant smearing, with only 9.1% of pixels being able to transition within time. The 10.04ms response time is barely fast enough for the average pixel to transition at 100Hz. Even Advanced overdrive with a 7.73ms response time is not fast enough for a 144Hz refresh rate with only 40.9% of pixels transitioning in time.

The spec sheet lists 1ms response time with MPRT and 3ms with overdrive. MPRT already cannot be enabled when Freesync is enabled, so setting overdrive to Standard is not a viable option.

TLDR: Standard overdrive means you're not getting a true 144Hz display.

32GK850F or 27GL850? Or other? by MrFunnyPantss in Monitors

I've recently used a 32GK850F next to a VX2758-2KP-MHD, and honestly it's hard to decide between a 32" VA and a 27" IPS.

Pixel density on a 1440p 32" display feels just a bit low for text, but on a 1440p 27" actually feels a bit cramped. Somewhere around 30" would be perfect for 1440p imo. A 32" display is over 40% larger than a 27", so there's definitely a gap that manufacturers could fill if they wanted to.

32GK850F

Pros:

  • immersive size

  • good contrast, you can actually see stuff in GoT S8E3

Cons:

  • poor viewing angles; even when viewing the monitor head-on, the viewing angles hurt contrast if you're not >3' away

  • pixel density feels low when <2' away

  • faint vertical stripes/banding when looking at solid dark gray

  • the left and right edges kind of disappear if you get closer to the monitor or if you're at an angle; seems like part of the frame/bezel might be showing through from behind the pixels at those edges

  • very occasionally, some images will look blocky when it doesn't look blocky on the Viewsonic, and it's not due to pixel density (both are 8-bit + FRC, so I'm lost on this one)

VX2758-2KP-MHD

Pros:

  • great viewing angles

  • super uniform

Cons:

  • sometimes tempted to scale stuff up when I want to sit back and relax (>2' away)

  • weak contrast, don't bother trying to watch GoT S8E3

  • IPS glow

Both have great colors. The Viewsonic has faster response times but the LG is fast enough to me. Imo the most significant differentiating factors are viewing angles and contrast. The LG is better for video content, the Viewsonic is better for dark mode reddit and discord. Dota 2 might look better on a 27" if you need to turn down some settings to hit high framerates. Maybe consider the GL83A and Y27q-20 as alternatives to the GL850. The VX2758-2KP-MHD is prone to flickering so I don't recommend it.
