i've had this problem since i upgraded my monitor to the benq xl2411p, using the dual port cable, my youtube videos look like this https://pasteboard.co/HKeA325.jpg

playing games it's fine but videos look terrible, could it be the dual port cable? or some setting i need to adjust?

 

cpu 4690k

gpu gtx 1070ti

ram 8GB (2x2Gb + 1x4Gb)

motherboard h97m-e

psu 750W

the cable or the monitor having problems, because that's what we can see from a screenshot.

looks fine to me

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - dark mode Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus thread, PSU misconceptions, protections explainedgroup reg is bad

if you took a screenshot and the image turns out fine, that means it's the monitor's fault probably. Do you mean display port cable? Or dual link DVI?

yes i mean displayport, can you not see the pixels in the image? because i just looked in my phone so it's not the monitor's fault.

Make sure your output is set to Full RGB or YCbCr 4:4:4  and not on YCbcr 4:2:0

It's DisplayPort not dual port .... hopefully that's what you're using.

 

Maybe try to set refresh rate to 120Hz and see if you still get image that's not good. In some situations, going to 144 Hz makes the card switch to the lower YCbCr 4:2:0

If you take a screenshot of what's on the monitor, that shows us the direct image that the graphics card has just rendered and pasted on your screen. You need to take a picture of the screen with a camera for us to see any imperfections.

The text is really crisp and the objects like the loading bar are very well defined, if you mean the black artifacts that's normal

why would we know? Print Screen only captures what the PC outputs, not what the monitor shows.

the pixels in the black background are very bad, another image https://www.imageupload.co.uk/image/TPzG

the image quality is terrible especially on dark colors, it's really wierd.

 

compare it to the actual video colors

Dude, when you use Print Screen , you get a picture of what the video card outputs, not what the monitor is displaying. So you can keep giving us screenshots and they would look good to us.

 

You would have to take an actual photo with your phone or a digital camera of the image on the screen, for us to see that bad image quality.

 

I already suggested your video card may output in YCbCr 4:2:0 which could lower quality , you never answered confirming or denying... check that first

 

And then , it's a monitor with a TN panel , which means that if you look at the image from the sides or from above the panel , basically if the panel is not straight in front of your eyes, the colors on the screen will shift a bit.

Even worse, it's a TN monitor aimed for gaming, for high refresh rate , not for good color reproduction.

The original XL2411 used a panel from AU Optronics and was designed to do 6bit + FRC , not 8 bit. That means the panel can only display around 260k colors, not 16 million, but there's circuitry inside which quickly flips between a bunch of those colors tricking your eyes to think one color is actually darker or brighter basically different... so in the end it makes it possible to show up to let's say 12-15 million colors... though how accurate colors they are I don't know.

Your s is XL2411P - i don't know if the tech is still 6bit + FRC or not ... it probably is.

 

If you mean the problem is ugly gradients... that can be caused by this 6bit + FRC deal...this faking of colors doesn't always work well with gradients and fade ins , fade outs etc
