AMD/ATI Pixel Clock Patcher

[daren@connectel.biz]

Hi Toasty, I utilized the pixel clock patcher and reduced the pixel clock rate to 150MHz and applied and bingo! worked perfectly my monitor displays clearly in 2560x1080 Mode. But, whenever my monitor/cpu goes to sleep or restart, it starts back in the original mode 1920x1080 (blurry and I have to reset it again) any ideas on how to change it and make it stick?
My setup:

Dell OptiPlex 980 SFF i7 Win10 Pro
ATI Radeon HD4550 with DVI output > HDMI cable convertor
LG Ultra Widescreen 34UM59-P Monitor

THanks!!
