Screen Display

Hi, I am running 32-bit Windows 7 Ultimate with a Sapphire Radeon R9 290X Tri-X videocard, Asus Z97 Pro Motherboard with an Intel i7 4790K Cpu at 4 Ghz. along with a Samsung S24B350 monitor using an Hdmi cable. My problem is that ever since I have changed from a much slower videocard to the Sapphire I have been unable to get the same full screen resolution as I had before, which was 1920 x 1080 x 60 Hz. Using Catalyst Control Center the best I can select is  1680 x 1050 x60 Hz. Sometimes this will change to 50Hz. especially if I use PowerDvd 13 and want to watch a DvD. When I restart my machine the resolution display may change from 60Hz. to 50 Hz. resulting in a smaller screen display. Can you help? Regards, Laurie

How are you connecting?
If you are using DVI make sure you have a DVI-D Dual Link cable.

I have been using an HDMI cable for some time, even with the previous videocard without any problems.

Yes, apologies you did say that in your original post.

It sounds like it may be an EDID error with the monitor not identifying itself correctly to the driver.

Did you have an ATI card in there before?  Have you replaced the graphics driver with the Disk from Sapphire?

If CCC isn't playing, try a 59Hz refresh rate
Otherwise it might be possible to edit the registry to allow an additional "unsupported" mode but if Windows is getting info through the HDMI cable from the monitor that says it doesn't support 1080p that can be a problem.

Were you using scaling with the older card?

This is my "go to" page for fixing EDID issues.
You may need to switch to DVI while doing it as you'll probably see more detected resolution options in the list that way.  Once a custom resolution is added you can switch back to HDMI and you should still see it.  For 1080p a single link DVI cable will be fine.

I have only ever used Nvidia cards before, without any issues. From the Catalyst Control Center Desktop Properties I can see a number of other resolutions up to 1920 x 1080 but I cannot select them. There are a number of GHz. numbers displayed from 25 to 75 Ghz. all in italics except 50 & 60 which are in standard form. Maybe the italic numbers are unselectable?
