NEC MultiSync FE2111SB 1600x1200 85HZ?

[Aeather]

As stated I have a NEC MultiSync FE2111SB that is connected to my R9 390 via VGA to HDMI.

I'm having issues trying to get it to 1600x1200 85Hz which it natively supports in the manual.


However, I am unable to get it to that while using CRU.


I patched my drivers using the tool for ATI cards.

When I set the CRU for that, while increasing the refresh rate it doesn't show up and when it does the image looks like I rolled the screen back on both sides.

I was able to use 1280x1024 at 90HZ however, I am wishing to use the native resolution.

I've tried HDMI to VGA and DP 1.1 to VGA.

I've taken out the 12th pin on my VGA cable, and I'm also getting a DP 1.2 and new VGA cable tomorrow to test out.

Shouldn't I be able to do 1600x1200 at 85HZ anyways? It should be under the spec of HDMI pixel clock.

Anyone have any ideas..

thanks

You didn't say you were using converters in your original post. Now you're talking about using two different types of converters. Converters have their own limitations. I don't know what the limitations are for your particular converters, but most VGA converters are only made to handle around 165-200 MHz pixel clock. That's not enough to get 1600x1200 @ 85 Hz with a CRT monitor.

This statement contradicts itself. You say it doesn't show up, but then you say when it does show up, the image doesn't display properly. When does it show up and when does it not?

Did you try the HDMI extension block with the HDMI-VGA converter? That should make the resolution available, but the converter might not be able to handle higher pixel clocks properly. I don't have a way to get around limits with DisplayPort converters.

Doing that prevents the monitor from being detected properly. You shouldn't need to do that if you're using CRU.
