* The only resolutions supported by the 13 year old 3007WFP and its DVI-D DL port are 1280x800 60Hz or 2560x1600 60Hz

* The 3007WFP was only tested/validated by Dell with a PC video card with DVI-D DL out port =
PC video card DVI-D out port --> DVI-D to DVI-D cable --> 3007WFP DVI-D in port

* Dell never tested this monitor with newer video card DP out port or HDMI out port. Using a PC video card DP or HDMI out port and conversion cabling will most likely only do 1280x800 60Hz

* Laptop docks that provide a DVI out port will also fail to do 2560x1600 60Hz and will max to 1280x800 60Hz

@Georgian0  Well that adapter should have worked.  It's the same type of product as the StarTech product I linked, so if it didn't work, I'm not sure what will happen with the StarTech option.  But the tech world is filled with cases of things that SHOULD work not ACTUALLY working, so it's possible that there's an interoperability problem with the specific combination of your GPU, that adapter, and your display -- a problem that shouldn't exist but does anyway.  In that case, trying another adapter might resolve the problem even if that shouldn't be necessary.  I've seen this multiple times with USB-C to HDMI adapters, for example.  Someone will report that their Dell laptop isn't working with their USB-C to HDMI adapter even though the adapter works fine with other source devices.  And multiple times after going through some other troubleshooting, I've suggested just trying another brand of adapter, even though that shouldn't be necessary -- and every time I've suggested that, the person has come back saying that another brand works fine with all of their devices.  Obviously a different brand of adapter shouldn't have made a difference, but it did.

One thing these two scenarios have in common is that DP to DL-DVI and USB-C to HDMI adapters both incorporate active converter chips in order to switch a DisplayPort signal to either DL-DVI or HDMI.  An active converter chip is a relatively complicated item, so any time you've got one involved, that's more complexity and therefore more likelihood of encountering strange problems.

Thank you very much for your comment.

I have tried this adapter https://www.amazon.com/gp/product/B07T16LLB8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 today, but it didnt work.

Can you tell me, will that startech adapter work for sure if I'll buy that?

Thanks in advance.

@Georgian0  The 3007WFP requires a dual link DVI input for 2560x1600.  Dual link DVI was always rare because at the time displays with resolutions that required its extra bandwidth were first introduced, they were incredibly expensive, and not long after that, DisplayPort arrived with support for even higher resolutions, which basically killed dual link DVI.  HDMI to DVI adapters only work up to 1080p resolution, regardless of which direction you're going with that adapter.  An HDMI output cannot send 2560x1600 as dual link DVI even if that output could send 2560x1600 as native HDMI to a display with an HDMI input.  And a dual link DVI output cannot send 2560x1600 as HDMI to a display that supported that resolution and had an HDMI input that would accept it.

If you want to run 2560x1660 with that display and your GPU, you'll need a DisplayPort to dual link DVI adapter, like this one.  And yes, they're pretty expensive because again, dual link DVI was uncommon even at its peak, and it's practically non-existent now, so there's not a lot of economy of scale to be had with these products.

Thanks,but problem resolved by change video card to an old version with DVI output.

I'm running my 3008WFP at full resolution (2560 x 1600) at 30Hz refresh rate using the HDMI connection.

It's possible a similar hack could work for the 3007WFP.

(It also works for me at 60Hz using a Displayport cable, but my laptop doesn't support that).

For HDMI, I added a custom resolution on Linux. The relevant information is the "modeline"

"2560x1600@30" 163.70 2560 2592 3208 3240 1600 1636 1644 1681

On Linux, that's easy to add using the xrandr tool.

I'm sure there's a Windows method, perhaps this works:

I have PNY GTX 1060 3GB that has a DVI-D dual link port pair with DVI-D dual link cable from Dell but it just show 1280x800. Is it possible that the monitor is not compatible with Windows 10 and New NVIDIA driver?
