显卡是 zotac 1050ti
显示器是BenQ PD3200U
4k/30P 没问题
4k/60p 正常网页浏览或者看 youtube 偶尔花屏一下闪一下然后马上就好了挺烦人的
hdmi和dp的线换了好几根还是解决不掉这个问题
请问有啥办法解决吗？
先谢了

有几个型号的BenQ 4k显示器有天生的缺陷，会时不时半边屏幕闪一下，或者干脆花屏。
一旦花屏只要关掉显示器再开就好了。
和用什么线，用什么视卡都没有关系。
据说某个型号可以通过升级firmware修好，但需要运回原厂。

整机配置说一下吧，如果是显卡不够，网页会闪就太奇怪了。我个人猜测是显卡，新的
还是二手的？具体型号呢？

好像不是半边屏花全屏花一下一闪而过立马回复正常不用关掉显示器再开 4k/
30p的设置没有任何问题

屏。

都是从官网买的翻新的第一个是evga 1030 4k/30p没问题 4k/60p 偶尔花屏一下
EVGA GeForce GT 1030 SC, 02G-P4-6332-RX, 2GB GDDR5, Passive, Low Profile
后来又买了 zotac 1050 ti 一样的毛病 zotac-geforcer-gtx-1050-ti-mini
https://store.zotac.com/zotac-geforcer-gtx-1050-ti-mini-zt-p10510a-10l-1447
机器的配置是 7代 i7 16gb 内存 1tb ssd 带两台显示器另一台是dell 2k的
显示器没啥问题

面板技术天生的毛病，没有救的。和我以前那个benq一样。看你能不能忍。
技术转贴：
The Issues:
I actually think it is nearly perfect for professional and private use, but
suffers from one flaw that keeps me from recommending it completely. It
suffers from an occasional left/right side single frame green/purple/black
glitching and artifacting that happens with ANY setup you use, no matter
what input you use, no matter how short your cables are, no matter how
shielded your cables are or how electrically "clean" your environment is. I
have spent a large chunk of time and money attempting to "fix" this issue
believing it to be my own, and even queried BenQ. Trust me, multiple DP 1.2
certified (Accell) cables, multiple GPUs (two Quadros, a Firepro, many GTX
1080(s)), multiple PCs, laptops, multiple UPS, even grounding wires and
armored 1" conduit have all been tried. I left very few stones un-turned.
A picture is worth a thousand words, right? So a video must be worth a whole
lot more. Attached is a video detailing the glitch that "RidingTheFlow"
from Youtube with an Acer XB321HK (that has the same M320QAN01.0 panel) has
taken.
-My thanks to YouTube user "RidingTheFlow" for capturing this phenomenon, as
my capture devices never captured what looks like a single frame glitch
properly. His video is attached for reference. The YouTube Video ID is "
gFDtw8jh-Cw." All credit goes to him.
One theory is that AUO's timing controller (TCON) implementation on this
specific panel is not entirely stable. Stable in that either it is not
thoroughly EMI shielded and is unusually susceptible, or that somewhere in
the design there may be room for improvement. They likely use two separate
TCON circuits that divide the panel into two halves where one TCON controls
one half and the other controls the other half. This would explain why if
the glitch/artifact happens, it happens on one half of the display. This is
a common setup for high resolution or high refresh (4K 60Hz+) panels when a
single off-the-shelf TCON will not support the bandwidth a high resolution
or high refresh rate panel needs. The multiple TCON setup is just a design
choice AUO made internally, there is nothing inferior or intrinsically bad
about it and AUO was most likely was making the most out of what was
available to them at the time of designing this monitor (before Q3 2014),
but the fact is both halves of the panel, therefore both TCONs, are
problematic in some way. Furthermore, this IS a Single Stream Transport (SST
) monitor, MST is not needed. In practice it is NOT a multi-tile display as
older MST panels were, and these are not MST-related issues.
Some users report the glitches/artifacting happening every half hour or so,
others report that they see it very infrequently. This could point to a
number of things, including EMI sources being more or less present in the
user's operating environment, or, indeed, a manufacturing inconsistency. The
EMI argument, blaming the problem on the user, should be null and void
though, as your average user is not using this monitor in a noisy
environment, or at least no noisier than environments where other panels/
monitors would not exhibit these issues. It is not like it all users
experiencing these problems just happen to be sitting right next to a 480V
VFD/PWM AC drive motor producing hugely strong electromagnetic fields. The
EMI these panels are seeing in your average setting is pedestrian, at best.
Now, this issue really is not an absolute deal-breaker for most users. It is
annoying, for sure, once you realize what that flicker was when you are
hard at work, but most people can probably put up with a mild annoyance. If
something like this would annoy you when you know other monitors on the
market would not have the same issues, keep looking at other options. This
monitor is excellent otherwise.
