Tried DVI-D to HDMI ... same as hdmi no more than 1080p

I added in CRU, on 12.6 drivers and it won't work.

So your trying to connect an older graphics card to a newer computer monitor or modern TV?
As you have already tried a (dual link?) DVI-D to HDMI cable and it did not work.
Guessing you need to get a newer graphics card.

Edit,
Is there any chance you were using a Single Link DVI-D to HDMI cable?
Where you should have tried using a Dual Link DVI-D to HDMI cable?

Only DVI-D to DVI-D will support 2650X1600 on the AGP GPU. No converters will work as HDMI 1 is limited to 1080P as the highest resolution. The 480X has HDMI 2 thus the cable supports 4K. Your limitation is the GPU, not the LCD.

The maximum pixel clock rate for HDMI 1.0 was 165 MHz, which was sufficient to allow 1080p and WUXGA (1920×1200) at 60 Hz. HDMI 1.3 increased that to 340 MHz, which allows for higher resolution (such as WQXGA, 2560×1600) across a single digital link.

I used a 24+1 pin Dual Link DVI-D to HDMI cable... 24+1 DVI-D Dual Link from the GPU to the HDMI port on the tv that supports 4096x2160 60hz native

Maybe I need a DVI-D 24+1 to DVI-D 24+1 pin to a converter box then to HDMI?

I was thinking of retrofitting to PCI-X to PCIe x16 and use a 1050 Ti 4GB LP or RX 460 MSI LP if the 4GB RX 460 MSI LP ever releases? It's cheaper and would be fine...
