Artefacts - Red dots/lines in dark shades of color

[DXMember]

So I get red dots/lines over shades of gray and blue colors

The artefacts appear even over OSD menu

This is an AHVA panel of BenQ BL2710PT

Does this look familiar to anyone?

Just filed Support/RMA ticket but it's Sunday...

are you talking GPU right now?

if not then I'd like to point out again - this also happens in monitors OSD and also shortly after the GPU shuts down and there is a "No display" notification with the backlight still on

that's the size of blocks you get when a gpu goes seriously unhappy.

my raspberry pi basicly does the same thing a few mhz before it crashes when OCing

 

although, if you mention it's also on the display's menu, it's pretty much sure that it's an issue with a chip in the display, rather than on the PC side.

monitor dead?

Ugh. That sucks. At least BenQ has awesome RMA handling and customer support. This is just bad luck. BenQ business monitors are actually very high quality. I have three BL2400PTs all with 8700 - 9000 hours on and zero issues since 2012. No dead pixels/flickering/bleed or other signs of old age.

my bet is on bad power supply caps.

 

monitors going iffy are generally related to input power, because *some monitor manufacturers* cheap out really bad on that stuff.

 

one of my displays actually gets better color accuracy when it's connected to a homebrew voltage dropper i made to take about 10 volts off of the input voltage.

could it be some kind of permanent damage caused to the panel by anything,

like let's hypothetically assume a scenario where a user might or might not run the display at a higher refresh rate than that specified by manufacturer?

if the display cant handle it it shouldnt try to display it.

 

all logic for displaying that refresh rate is in the display, and your computer can output what it want, if the display says "i cant do this" it wont do this.

let's assume that this hypothetical user's display did in fact complain about the output being "Out of Range" a couple of times, but the user might have found a refresh rate that is below the "Out of range" error and still above manufacturer's specification, like for example let's assume a display that is supposed to run 60Hz by specification manages to accept a 70Hz input

it accepts the input, so it should be capable of handling the input.

 

the moment it goes out of range, the display's internal logic tells you it cannot do this.

if it'd break at 70Hz, it should say "out of range" when you do this. (like all of my displays do, fyi.)

Left the monitor unplugged over night and it fixed itself

thanks.
