DVI issue with LG Monitor

Greetings again. so to make it simple i made a thread not to long ago about a related display issue here > HDMI issues with LG Flatron M2294D ?

and was adviced that possibly getting a dvi cable would fix the issueim currently having with my VGA cable. long story short!

VGA cable is becoming a nuisance show static interference that is noticeable when the screen becomes darker. like vertical waves on the screen. depending on the cables position its either quite noticeable to look at or none existent.

so i have thus done some research and found my monitor accepts DVI-D dual link and the same goes with my graphics card. so ordered one of amazon. arrived today! annnddd... not appears to display when switching to the dvi mode

at first it was on power saving mode. turned on the PC that went away but it was just displaying blank. so at this point ive pretty much got the feeling im stuck with VGA until i get a new monitor!

its definitely not the PSU or the graphics card / motherboards fault.

anyone got advice on if this problem is even worth fixing ?

Does the monitor automatically switch to DVI when a DVI cable is connected (and the VGA removed)? Some older dual port monitors required a manual setup to accept DVI.

Problem may not be the monitor but a problem with the DVI port in the video card. I would get (or borrow from a friend) another monitor to test.

my GT640 has 2 DVI ports ive tried both. and as far as im aware no it didn't automatically switch to the dvi mode on the monitor. pretty much all i done was shutdown PC unplug VGA and then plug in DVI and switch from VGA to dvi mode in the monitor.

in all honesty it could just be the monitor. its at this point its like 8-9 years old. i wouldnt have a doubt in a mind if it wasnt the monitor

also id like to clarify that none of my mates have spare monitors to give for testing. and i highly doubt they they will lend a monitor.

i just dont get why it will only accept VGA. this monitor has served me well for nearing a decade now but with the slow and painful powering issue for the monitor. i might be ready to boot it and get a new monitor

Only thing I can think of is VGA is analog, and DVI is digital. It could be that the digital side of things has failed? Have you got a TV cable box etc with an HDMI out to test that monitor on? You'll need an HDMI to DVI adapter which are inexpensive.

i mean the only thing i can think of is the downstairs living room TV. has HDMI ports and is currently working fine considering its connected to sky box (basically a satellite TV player)

These days a TV can be a monitor and a monitor used in place of a TV. When all that's being used is HDMI in. If it's not a smart TV the only difference is one has a remote and the other doesn't. I often wonder why I buy a TV? The tuner part is never used?
The only thing you lose going HDMI to DVI is the sound part of the HDMI signal. No big deal if all your doing it testing to see if you get video or not.

indeed. this is a TV, but ive used it for so long for its only purpose being for the PC that i just ended up calling it a monitor for ease of use really

also i did try HDMI and it seemed to have worked fine. granted my crappy GT640 was trying to push 4k but was so god awfully laggy xD. but hey it worked! still a question to be asked tho is if the DVI-D cable works.. but i wont know that until i find a monitor to buy
