My Acer XF270H text quality isn't as good as it used to be

[ShiWarrior]

interesting

plugged in HDMI lead and took out the DP lead

still running at 1080p (good)
dropped to 60 HZ (understandable)

Bit Depth has increased from 8-bit to 10-bit
and the quality has improved back to how it should be ?

plugged DP cable back in, crap again
maybe its the DP cable or DP port ?

i got a DP converter cable coming, so at least i can test the port

 

[ShiWarrior]

i think its getting worse

arrived today , was a DP to DVI (female)
so im using my DVI cable , connected to DP socket on the graphics card to see if its actually the DP connector on the graphics card, its an improvement over DP to DP but not as sharp as HDMI


ive been using the DP to DP cable that came with the monitor, is it worth buying a better one?

Cable was going to be my first suggestion, aside from making sure the cable is plugged in fully. Also try a different displayport on the graphics card if you have one.

Make sure you haven't got chroma subsampling enabled, that can cause text to look awful (it maybe enabling that with the DP cable?)

I've only tried different dp ports on my gpu, and tried a DP to DVI cable

I thought about buying a new cable if the ones supplied aren't very good?

Never heard of this, how do I check ?

 

[Haggisman]

Open the Radeon software
Click the cog in the top right for Settings
Select Display in the navigation bar
Check under Pixel Format and make sure it is NOT set to YCbCr 4:2:2 Pixel Format - you want RGB 4:4:4 Pixel Format PC Standard (Full RGB):

Cheers I'll take a look later

 

[ShiWarrior]

ok, checked it and yes it has that already selected , so its not that

 

[ShiWarrior]

ordered a new DP cable 1.4 one
if that doesn't work, new monitor ??

 

[Haggisman]

Have you tried setting it to 1080p/60/10bit (e.g. same as it switches to with HDMI) when plugged in via display port?

 

[ShiWarrior]

good point, not sure if i tried that one, will try it and report back
thanks

I would just buy a new DP cable if I was you.

Any luck with this?

Any luck with this?

I'm not at home lol
I will try it later

 

[ShiWarrior]

well
I've just tried changing from 144HZ to 60HZ and no other settings (yet)
and its an improvement, not the best, but its better

 

[ShiWarrior]

cant change the bit depth to 10 (tried in my Graphics card settings and windows) i can only have 10 but on HDMI

must be the cable surely ?

i will find out soon enough !

 

[Haggisman]

That's really strange, if it supports 144hz then 10 bit @ 60hz shouldn't be a problem, definitely give the cable a go, failing that completely uninstall the amd driver, use DDU to get rid of any saved settings and then do a fresh clean install

 

[ShiWarrior]

new cable arrived
put it in, first thing i noticed it seems more vibrant

but Text still not good, but a little better because it just seems more "vivid" and more "vibrant" than before

still cant change to 10-bit @ 60 Hz
