I have been using a six foot VGA cable with my Acer G276HL for some time (presumably using the 6' cable that came with the monitor). After installing some new cabinets I needed a 10' cable and ordered one online. When I installed it, I noticed that there was no longer an option to select the normal 1920x1080 reslution, and the monitor was listed as a generic non-PnP monitor. Putting the old cable back on solved the problem. I then ordered a cable (described as a "premium" cable) from another online vendor, and the same thing happened again. With both orders I also noticed that the cable did not match the images on the WEB sites, which showed a thick cable with two ferrite cores. Both received cables were missing the ferrite cores. I am assuming that both cables were missing one or more connections. Question: Is my assumption correct, and is there a U.S. vendor where I can expect to receive a 10' cable that works correctly?
 
Solution
My VG248QE displays as Generic non-PnP as well yet it still has the newest drivers and detects the 144Hz refresh rate, as long as you are not having any display problems this should not be an issue.

Solution

In my case the maximal selectable resolution with the new cables was 1600 horizontal instead of the native 1920 x 1080 widescreen resolution, and the display also seemed a little distorted and fuzzy to me. The selectable resolutions went back to normal when I put the old cable back.

 


Has anybody found a solution to this? I have the extact same problem where the monitor works correctly in native resolution with one cable but with another cable it can only run in Generic PnP. So, it's obviously not the drivers on the computer but the cable. When I look online for this problem I only find people talking about fixing drivers and this and that but nothing recognizing a problem with the cable. Are VGA cables manufactured differently these days?
 

Yes, I did find a solution. My bad for not updating my post. After trying two different cables that did not work, I finally ordered a CablesToGo 50213 Select VGA Video Cable from Amazon (http://www.amazon.com/gp/product/B00CJRRTYM?ref_=cm_rdp_product). I think you can also get it directly from CablesToGo. Unlike the old analog-only 640x480 days, some of the pins (pins 11, 12, 4 and 15) are now used to identify the monitor, and some cable manufacturers apparently do not connect all the pins.
