Have updated the driver, have downloaded and installed the AMD settings manager... it just says that the 2560X1440 is not compatible w/ the display.
ViewSonic driver installed, not the PnP from Microsoft... still no good.
DisplayPort or HDMI?
If I click on screen resolution, advanced settings, the adapter tab, the list all modes button, the drop down menu stops at 1920X1080?
I have looked up the specs on the R7 250 and CNET says HDMI: 4096 x 2160 / VGA: 2048 x 1536
Have you tried another cable?
Yes. No luck with that.
What if you do use the generic driver? Also, is the refresh rate set to 60hz?
I started out with the PnP driver and it would not give me the resolution, so replaced that with the Radeon driver, which wouldn’t work... I am now suspecting the cable, so have ordered a new one just to make sure it is 1.2a (I think the others were, but think didn’t work... I want to know for sure) so have ordered a new cable (not avail locally)
Your cards probly not capible to run such high resolution is suspect. Its technically a low end card so drop your resolution back the only way it will work properly. Never ever go of CNET actually look around for reviews & specs. The R7 250 is spec wise same as the RX550 you achievimg a big feat out of a gutless card. If you want decent resolution u need a grunty card or stick with 1920 i would hate to say.
Thank you. I have ordered a new Displayport 1.2a to HDMI to make sure the cable is not the choke point. If that doesn’t work, it’s the card.
