I have what I think to be two hardware questions, although possibly I am looking at a software answer. It is associated with a planned LEAP-15.2 to 15.3 update.
I think I know the answer (to both questions) but I thought I would ask to give me confidence I have not overlooked anything.
1st question: Will the output of an old nvidia GTX-260 graphic card (using a DVI to HDMI adapter) display OK on an ultrawide LG29 monitor (capable of 2560x1080p resolution) at a lower resolution?
I don’t care if I don’t get 2560x1080p resolution … as I simply want to connect for a few hours to update the desktop with the nividia GTX-260 graphic card from LEAP-15.2 to LEAP-15.3. Once the update is successful, I will disconnect the LG29 monitor and connect to the desktop ‘headlessly’ (ie via ssh/vnc).
I suspect the answer is ‘yes’ this will work (giving 1920x1080 with black bars on either side of ultra wide monitor).
- the GTX-260 grapic card supports 2560x1600, it has only DVI connectors,
- the LG29 ultrawide monitor supports 2560x1080 , it only has 2xHDMI and 1xDisplay Port.
- To connect the two I pondering to use a DVI to HDMI adapter to connect the graphic card to the monitor with an HDMI cable. However I have read DVI to HDMI adapters only support 1920x1080 resolution, which is fine for me … But will the LG monitor display at 1920x1080 resolution with the adapter in the electrical connection?
- This is for only a very brief few hours connection.
Surfing on that has not yet given me a definitive answer (I suspect the answer is yes - however I have read of users with different monitors saying DVI-to-HDMI to an ultrawide monitor fails for them).
2nd question: Am I better off paying more money buying a “Dual Link DVI” to Display port adaptor and also buying a display port cable (for only a few hour connection) ? I have read the nvidia GTX-260 supports Dual Link DVI (which will support up to 2560x1600)? I don’t particularly care for this route as it means spending more money.
I suspect the answer is yes this will work, but I will need to buy a ‘dual link DVI adapter’ and buy an appropriate Display Port cable.
Background: A few more details (likely not so relevant - so it can be skipped) :
This is on an ancient core-i7-920 desktop running openSUSE-LEAP-15.2 that I plan to update to LEAP-15.3. The monitor I use with this desktop long since died, but that was no bother as its my 3rd PC and I simply connect to it headlessly via ssh and vnc over the family LAN. The desktop is sitting under a desk with the LG29 monitor, so the connection would be easy to make (the desk and monitor are used nominally by my wife for use with her laptop).
3rd approach I have not considered: I have not done a ‘headless’ upgrade to from one LEAP version to another LEAP version (which I suspect may be possible) but since I don’t have that GNU/Linux experience I don’t have the confidence that if I try that, that the upgrade from LEAP-15.2 to 15.3 will work. Hence my pondering to use a DVI to HDMI cable (and sort of rejecting the Dual Port DVI to Display port adapters approach to save money - after all this is a VERY OLD desktop).
In summary questions:
Will the DVI output of a graphic card display ok on an Ultrawide monitor at a lower resolution? (lower resolution as its driven via a DVI to HDMI cable)?
Is it a better/safer approach to use a Dual DVI to Display Port adapter to connect graphic card to the Ultrawide monitor ? [which means spending more $$]
I would be curious as to any experience.
