  1. That message is usually a refresh rate issue in my experiance. Usually its set to high for the monitor. Open up the CCC and see where its set. There is obviously something wrong with the drivers of one or other, As the BenQ isnt being recognised i would sugest re-installing the Monitor drivers as well.

  2. i downloaded the driver from the Benq website last night and put it in c:\windows/system32\drivers. so what else could this issue be. i tried screenshoting the screen with how it acts in 1920 x 1080 but it didnt work, just came up as the clear desktop when i pasted it into paint to save it
  3. What do you mean you put it in c:\windows/system32\drivers. You do realise you need to actually "Run" the driver application so it can install itself ? Its not just some code that needs installing to a directory.

  4. well i extracted the drivers from the zip file and its not coming up with anything to actually run them
  5. Well you have to run the drivers or you wont get anywhere, What about the driver disc for the Monitor i guess you dont have that anymore ? If so then use that.
    If you can post a screen shot of what you got when you opened your Zipped file i will take a look and soo if there is an exe file or some such so you can run the drivers manually.

  6. here screenshot of the driver folder i downloaded from benq support


    as for the driver cd, my monitor didnt have one in the box when i bought it/ and the shop i bought it from is closed down now
  7. just found Powerstrip, which supposedly lets you ''customize resolutions'' however Advaced Timing Options are greyed out so cant even do that lol
  8. Just been to BenQ and couldnt find any drivers so your one up on me there already. What you posted dosent look right at all. If you cant find a set of drivers to download from a third party then maybe you could find a driver disc on Ebay if every thing else fails. You do need the drivers though.

  9. max rlution i can get is 1600 x 1200
  10. Quote:
    downgrade to previous driver.proably cat10.3.Then connect ur monitor to the second dvi port of ur card.If this donot help i smell a bad card RMA it.

    the a did not work either :(

    ive gone back to using my 9800GT and all is fine now....called up Benq, will try again when i get the driver CD
  11. trying my 5770 after bad fps performance, seem to have misplaced my receipt for it, if it doesnt work when i get the cd for the monitor drivers ill just go buy a nvidia equivilent

    downloaded the Benq driver installed it with going to device manager > monitors > properties > update driver > have disk > "browsed to the location" > next > then reset and no change
