I bought this Dell 3007WFP 30" monitor in 2006/2007 and am trying my best to repurpose it, but I'm having a very hard time. First I tried to get my Xbox 360 to go through it, but apparently that's never going to happen unless I buy a hardware video scaler. So I thought I could use it as a second display for my laptop since I know my laptop can scale video. However, when I run an HDMI cable from my laptop to a DVI-D dual-link adapter to my Dell monitor, the only resolution the monitor advertises is 1280x800 and I can't get my laptop to display any other resolution on it. Is there anything else I can try to get this to work? My laptop's video adapter is a GeForce GTX 860m.
I found this post on Tom's Hardware and bought the StarTech USB3-to-DisplayPort adapter, and the active DisplayPort-to-DVI cable. The result was the same as when I tried HDMI; it displayed fine at 1280x800, but not at 2560x1600. There were just a bunch of thin lines on the screen. Some where scrolling down and some were stationary. I contacted StarTech support numerous times to troubleshoot. I tried the setup with another computer and had the same result. I tried a new adapter and a new cable and got the same result. StarTech told me it might be that the USB port might not be providing enough power and recommended I add to this setup a DisplayPort-to-DVI dual-link active adapter converter. That would take up another USB port on my laptop.
If power is the issue, I'm investigating just buying a powered USB 3.0 hub and plugging this DisplayPort adapter into that instead of my laptop's USB port. However, in reading the specs of new USB 3.0 hubs, I see that there are often warnings that some devices require a direct connection to the host's USB port. See this Anker hub as an example:
Additional Notes: • Some USB 3.0 devices require a direct connection to host ports. • 2.4Ghz wireless devices (keyboards, mice, etc.) may not work around USB 3.0 ports. Try using a USB 2.0 connection instead.
How do I know if a device requires a direct connection to the host's USB bus?? It seems like this is extremely variable and doesn't affect all USB devices of a given class, such as all external hard drives or audio interfaces. Very frustrating when I'm trying to find a definitive answer on these things. :-) Particularly when by all accounts (confirmation from manufacturers, technical specifications) what I've tried so far should work.
So now I'm evaluating my options and pricing these things out. I'll update when there's more info.
