Glad to hear it's working ]]> https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#7 Thu, 05 Dec 2024 12:38:25 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#7 DisplayFusion wait!! its working now at 60hz for 640x480! its doing some weird thing where its changing 3 frequencies before it hits 60hz, but it is working! i wonder if its trying to do 75, 70 before settling on 60? this is awesome thanks!! i can use the hotkeys now without faffing around with windows. thanks! do you think this will be tweaked for other resolutions and frequencies at all? would be nice to go higher than 640x480, but im happy for now just having the monitor working!! ]]> https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#6 Thu, 05 Dec 2024 12:30:24 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#6 DisplayFusion hmm, tried that now. unfortunately still the same. you can see all the weird freqs its trying attached... ]]> https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#5 Wed, 04 Dec 2024 14:18:50 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#5 DisplayFusion Yeah it's never usually exact, it will find a timing close that's compatible. We've reworked a bunch of our monitor config code in our latest beta, can you try it out and see if the issue persists? ]]> https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#4 Tue, 03 Dec 2024 14:48:02 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#4 DisplayFusion Just as a further info - in windows if i set the monitor to 60hz it does the same as display fusion, but when you look at the actual freq its 60.02. if i then go into advanced settings i can see an option for 60hz, and this works and its shows then 60hz. im assuming display fusion is doing the same, where its not on but timing is out a few decimels? hope this makes sense? ]]> https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#3 Tue, 03 Dec 2024 14:42:57 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#3 DisplayFusion Owen, i never saw this reply and didnt get a ping in my email. this is still a problem and drives me crazy. it seems to me that display fusion isnt hitting the right decimals for the frequency refresh rate and knowing the CRT out. windows does it ok at 640x480 @60hz. i discovered today if i shift to my onboard GPU it allows 59hz which seems to work, but the annnoying thing is when i connect my main gpu (3080) i only have 60, 70 and 75hz available none of which work, though i know my crt monitor does these freqs for sure. its just the timing is out slightly... attached is the log.. sorry for the delay, hope you can still help.. thanks ]]> https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#2 Mon, 15 Apr 2024 14:04:46 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3#2 DisplayFusion Could you download this test tool and copy the output to a notepad file while the refresh rate is set incorrectly, and send it over? https://www.binaryfortress.com/Data/Download/?DownloadID=495db9ad-a9fe-4bee-a23d-d9cf233a7b1b&Log=0 ]]> https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3 Sat, 06 Apr 2024 17:05:58 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/old-crt-not-working-with-refresh-rates-though-windows-does-help/?ID=018eb45f-bef2-70de-8efd-75b0a0a321e3 DisplayFusion I know this is old stuff, but i like CRTs for dos gaming on windows 10. if i configure my (licensed) display fusion to use say 640x480 at 60hz it displays a screaming screen like its outside of the hz range. if i do the same though in windows by listing all modes and selecting the same resolution and frequency it works fine. go back to display fusion and ask it to do the same, again an insane range/output. not sure why its doing this! if its the same res and freq why would it do it differently? anyone else using old monitors as secondaries? thanks! ]]>
