This isn’t a tech support post, more like a rant post. On the 7800xt a common issue is that if you run a hdmi monitor and a displayport one you get constant greenscreens unless you lower your clocks (which for some doesn´t even work). Thing is, that this was reported months ago and no solution has been made from AMD to fix this. I am very pissed off by this, because I was pretty sure that driver issues were a thing of the past, and if there were some issues they would get fixed at launch… (It isn´t windows only, the green screen comes in arch too) well nah, amd doesn´t learn. Another thing that makes me worry is that AMD doesn´t look like they will catch up to nvidia anytime soon, hell, FSR3 is still not released…

Was the 4070 ti the better choice? At this point I don´t know.

    I’m using all 4 outputs on my 7900XTX (3 DP, 1 HDMI) and do not ever have this happen. Make sure you’re using good cables, cheap DP/HDMI cables cause a maddening amount of issues.

    Hmm happens in 2 completely different OSs that are definitely using completely different driver builds and code to interact with the card. Clocks are not the issue.

    I call out the issue is actually with the monitor especially if it’s a green screen. If possible try a different monitor. or a different refresh. Most of the issues people are seeing like this or issues with power draw on idle, flickering refresh, etc. are due to monitor manufactures fudging the specs and actually running the monitor outside of VESA standards.

    The other thing to check to see if your monitor has a firmware or driver/profile update.

    Heck it can even be a subpar hdmi/Displayport cable.

    I’m still waiting for them to address whatever it is that turns the preview window (and subsequent renders) in Vegas Pro 15 a fetching shade of blue.

    Or would that have simply been cured with a Reboot?

    Not sure I’ve ever heard of this one before, and I’m using two DisplayPort monitors and one HDMI on my 7800 XT.

    You could try asking u/AMD_Vik to see if he knows anything about it, he’s very knowledgeable and might be able to help.

    I feel like this is one of those HW faults that can be hidden to an extent by the driver updates or get fixed in later revisions. But I might be completely wrong, I just thought it had a faint smell of the 5700XT

    The Nvidia glazing is crazy by some of y’all. Any attempt at troubleshooting? Replacing cables? Using display port for both monitors? Also the 7800 XT doesn’t compete with the 4070ti that would be the 7900 XT. Only issue I’ve had with my GPU is the custom fan curve reset and that was a windows issue that has been resolved I use 2 monitors both with display port and no issues.

    I’d just return / RMA it. No way I’d go to the point of downclocking a card that’s supposed to work flawlessly out of the box with their given manufacturer specified clocks. I’m personally tired of beta testing for big tech companies. It’s the only way they’ll learn anyway.

    AMD just doesn´t care about driver issues it looks like

    Constant driver updates seems to negate this.

    you get constant greenscreens unless you lower your clocks

    Many people in the forum are saying the problem is when the card is overclocked. To quote one poster “Adrenaline software max freq was 2565MHz when AMD itself says max freq is 2430MHz”.

    the green screen comes in arch too

    Why are you assuming a driver issue, this could be bad VRAM.

    AMD doesn´t look like they will catch up to nvidia anytime soon

    What does this mean?

    FSR3 is still not released

    It has already started coming to games.

    First i’m hearing of anything like that… sounds like a gpu issue…

    got plenty of people using dual and triple displays on 7800xt some of which are using DP ~> HDMI as well to connect their displays.
