i can get 100hz working perfectly with a pixel clock :300.25mhz
now when i try to go for 120hz i can only seem to get 109hz locked with a pixel clock at :327.00mhz this is where im stuck i can not for the life of me get over 327mhz im stuck and for 120hz i need over 370+mhz why am i stuck here

I've never heard of a 327 MHz pixel clock limit. What happens if you add the resolution with CRU? Does the resolution not get listed?

Text will only be sharp at the native resolution.

hi yeah mate 327 seems to be the max ? if I use cru the resolution does not even get added if I select 120hz
if I select 70-72-85-100 they will get listed fine cause there all under 327mhz pixel speeds that's @native 2560x1080p

if I select 120hz it does not get listed, sometimes it does get listed though and produces a black screen when applying it.

and if I use a program called AMD downsampling GUI
and select 2560x1080p then input a pixel speed of 32700 and a resolution of 120 then apply the display will show and it will say 120 but when I run that blur overclocking test it shows my max frames as 109fps.....

without a higher pixel I cant reach 120mhz 120fps.

everytime I try to enter a higher pixel I get a ADL_resolution override failed error even 32701 does not work lol its like im limited or something, im running displayport mini cable to displayport cable my graphics card is 1.2 dp compatible and my monitor is saying 1.1a compatiblilty and not showing 1.2 could this be the reason why I cant get past this pixel limit. im sure I read somewhere that dp does not have a limit or if it does it should be able to reach 400+mhz easy.

the cable I have is a cheapo cable 8.6gb bandwith max I think
though not sure its a cable issue I have but just to check I ordered yesterday night : http://www.amazon.co.uk/dp/B00A7R9I2M/re...51_TE_dp_1

acctel 1.2 dp cable heard that, that cable is uber .....

just hope its a cable issue but I don't think it is as you would have said...... need help with this badly cause if I could get a higher pixel limit I could get to 120hz easy.
