GPU overclock messed up screen resolution

[CastleCrusher]

So this morning I tried to overclock my Vega 8 igpu to 1600mhz. My system is stable but that's the least of my issues. When Windows boots up and my 2 monitors get recognized, my secondary one says the current settings are H=67.5kHz V=60Hz. The recommended settings are 1440x900 at 60Hz but the current one isn't even a resolution if I'm correct. After that brief monitor status menu goes away, it tells me "Input signal out of range Change settings to 1440x900-60Hz" even though it's set to that in Windows. Then it goes to sleep after a while. When I open up the settings and go to advanced display settings, my main display is at its default 1600x900 which matches the desktop, but my 2nd is at 1920x1080 which isn't even what it's set to. So the problem is that my monitor is set to the right resolution in the settings, but it shows 1080 in the active signal resolution. Even putting my overclock back to default doesn't change anything. My second monitor is an HP LE1901 running off of a little DVI to HDMI adapter with the HDMI cable connecting to my PC. Thanks in advance.

That's maybe because a converted cable typically caps at 1080p resolutions, try DVI->DVI or HDMI->HDMI see if that changes a thing.
(in other words it can cause instability with resolutions/etc)

I'd definitely check the cable too to see what you exactly have. DVI-D dual link or?

I recently ran into a problem with my monitors where through DisplayPort TV resolutions registered in the EDID would override and tell my screen it was 1080p over 1440p.

Found out the hard-way that I needed to customize the driver and all sorts but get back, I'm sure this is sortable.

I don't have a DVI-D cable on hand but when I use a VGA cable on either of my monitors, they work completely fine. Any other combo (DVI-D adapter to HDMI to DVI-D adapter or DVI-D to just HDMI) messes everything up on both monitors. They are too old to have HDMI so will an actual DVI-D cable change anything?

Hmm, it does look like it detects the right resolutions but doesn't show it for some reason. I don't think it's cables this time, but keep an eye on bad conversions it can limit you hard.

Download and update the driver for your monitor, the generic one may not be doing you any justice. If this doesn't work, we can try custom drivers, perhaps a built in feature is toggling something to break.

I already tried that but after spending an hour trying not to get a GSOD, I gave up on overclocking my Vega 8 igpu. After I did that, by some miracle my monitor went back to normal like I never did anything, even though I did temporarily back off of my overclock and it still acted up. Thanks for the help though. Computers and their accessories can be weird sometimes.

HDMI to DVI cables (or the other way around) are generally passive cables, just changing the connector, but the wires electrically connect directly with nothing in between.   The question here we need to ask is are we going from single link DVI-D to Type A HDMI, or dual link DVI-D to Type B HDMI, and even then, I thought OP said the monitors real resolution is 1440x900, so a regular 'ol single link DVI-D to Type A HDMI is all that would ever be required.

Yeah, I misread the initial post. Took a few re-reads.

Did you adjust the base clock (BCLK) at all? Might have caused the issue if it was changed at all.

Right now I have everything back to normal and my second monitor works as it did before. I think everything got fixed when I clean installed the latest stable drivers. But I lost the silicon lottery and it seems that overclocking my igpu isn't going to happen, even when using stock clock speeds with the igpu at 1300MHz.

What's your CPU BLCK value set to, have you done any overclocking with the CPU and/or tweaked the bios any?

Yes, it all started when I overclocked my igpu. I tried going back but even when the gpu was set to default, nothing changed. My cpu is overclocked to 3.9GHz and has been doing me fine. Haven't messed with my BIOS in a while and the igpu has always just been left to auto. 

 

Btw, my monitor is back to normal, I worded that one post weird.

Can you double check to make sure the BLCK is set to 100MHz on the CPU in bios?

When playing with multiple clocks syncs can fall apart.

You mean the stock base clock speed of the Ryzen 3 2200G right? The CPU was at 3.5GHz but I overclocked it to 3.9. Why would it be at 100MHz? Do you mean the GPU or am I just confused?

Base clock isn't the core clock.  Base clock is what your CPU multiplies from to get the core clock.  But I honestly don't think that's the problem, it wouldn't be affected the GPU (which is discrete, not an APU).

Ah ok thanks, either way my monitor is back to normal and all I do to overclock is dial in the appropriate frequency, adjust the voltage and bam, 3.9GHz stable. So I never messed with the base clock because I never overclocked using that method.
