Pink tint with new external monitor

Ok, yes - both are Acers - same generation, connections, just different screen-sizes. The 21.5" has a DVI and VGA port.

As such, on the Mini (i7 Late 2012) I have my 23' main monitor connected using: HDMI>DVI.

I was running Tbolt(Mini DisplayPort to VGA on the 21.5" external.

I gather then I need to try strictly going Mini DisplayPort to DVI for the external(2nd) monitor.

An update - I did switch out the VGA cable i was using (a long run - abt. 25 ft) for a heavier-duty one and got

rid of the tint - yet instead of a clean duplication of the main display, i got a "ghosted" display of it - i.e. color

correct but somewhat blurred icons/text - unfocused... still unusable. So is it possible going DVI will eliminate that issue? (Just asking since it entails yet another in a long history of cable purchases - in this case a long-run DVI for the remote monitor).

Thanks for your help!

Hi, thanks for your links- much appreciated. I should've thought about the longer-run possibly causing the degradation or anomalies -- i'm an audio guy and usually a 25-30 foot run isn't an issue - Acutally i did wind up

ordering a long-run DVI cable ( a 25-foot with decent shielding) so i'll see how that goes -- figured it's worth a try and can always return it

if it fails and try a higher quality long VGA cable per the article(s).

Thanks again,

Mike

Thanks, will take a look at that.. Actually other than that double-vision blur on everything on the remote monitor the color on both seems to match identically but there again, maybe a product of the cable being inferior...

There is one other question on this if you don't mind. I wonder if the fact that one is a larger screen-size and the other is a 21.5 size - would possibly make a difference as far as causing this blurred effect on the smaller monitor.. My thought was that so long as both monitors were able to handle identical resolution specs, the screen size was not an issue, that is, a 23 inch master monitor is connected via DVI>HDMI - and the 21.5 inch with the long-run cable to another room - is connected using the MiniDisplayport>VGA cable. The latter one gets the color right but has a blurred image apperance.

Sorry to drag this one out...just trying to explore all considerations in my process of elimination

Thanks again!

Ahh thanks for that. I was afraid of that possibility... Hmm, maybe have to try and see if i can return the 21 incher to match the 23 inch.... 'always something...' !!

Actually there's another option that came to mind - well, not sure if it is an option or not. Is there such a thing as a video monitor switch box which would allow me to select between Monitor A and Monitor B - in other words, so it wouldn't really matter what kind of resolution each individual monitor had - one could be 21 " and the other a 24" - and all i would be doing is switching the video out to read either one or the other at a time -- then i wouldn't even need to use 'mirroring' AFAIK and it would solve my goal of being able to go into another room and use the display independent of the other one - and vice versa.

ANy idea if such a device exists and any reason that wouldn't logically work?

Thanks again - and sorry to keep dragging this topic out - just pausing to reflect before i go selling off the 21" monitor to buy a matching 24" one just to get an external monitor to give me the same clear signal as the main monitor.

Regards,

Mike
