Title: ryzen 3 2200g + adrenalin crt_emudriver problems
Post by: webodan on August 25, 2019, 08:29:26 am

Hi,

I'm having problems with crt_emudriver 18.5.1 & the vega 8 igpu of the ryzen 3 2200g in an a320m-k motherboard (this has a VGA output, which I'm attempting to use for 15khz). I simply can't get this to work :dunno



I enabled edid emulation on the correct output and used the proper super resolutions like I usually do after installing the driver itself.

No matter what I do, the CRT screen just won't work, it gives me "mode rejected by driver" every time I try installing the video modes in vmmaker. And it won't show up any custom video modes or display anything at all.

I then tried dropping in my old ass hd 4250 + the 12.6 driver, just in case it could be something else... And that worked first try.

Can I please get some help? Calamity?  :'(

Thanks in advance.

Check my thread about the Asrock Deskmini A300.

If that’s the hardware I think it is (pretty sure it is) then it won’t work over the VGA port.  The integrated APU does output an analog signal via VGA, but as Calamity confirmed on other posts he is blocked from accessing the port with the modified ATI drivers that he wrote.

You can still use the HDMI port and buy a HDMI to VGA converter and it will work.

Here’s a lengthy discussion on it:

Oh..... Thank you, should've rtfm'd first.

Good thing I got an r7 250x lying around that should work fine

It does work over the VGA port, indeed it's more convenient than the HDMI one. But it won't support interlace nor EDID emulation. The later can be sorted out by means of the CRU tool. Aside of that, it works.

How? could you please elaborate on this? i'd rather use the vega 8 igpu instead of this old r7 250x if possible.
