Since my current monitor appears to be slowly dying, I'm looking for a replacement. I generally use hardware replacement as an excuse to get something bigger/better/faster than what I had before, so I'm currently considering something like a BenQ GW2765HT. The manual for my Intel motherboard has this to say about DisplayPort on the built-in graphics controller: QUOTE: DisplayPort?s maximum supported display resolution is 2560 x 1600 at a 60 Hz refresh rate with a 16:10 aspect ratio (WQXGA). END OF QUOTE It also states that the maximum supported resolution on the built-in DVI-I port is 1920x1200, which is the resolution of the monitor that I have right now; the one that appears to be dying. Therefore, this new monitor wouldn't work at full resolution with that output. Having never used DisplayPort before, I'm wondering if this means that if I purchase the BenQ monitor above, or something similar, I can then reasonably expect to plug it in and have it just-work with my Centos 7 setup. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com
As long as you have the DisplayPort connection on your computer and you have the proper cable to connect it to the monitor then it's no trouble. I had been using dual DP monitors on my last work machine. Also, note that sometimes the PC end is normal DisplayPort but sometimes it has a mini DisplayPort connection. Just get the right cable and it should be as simple as HDMI.

DP is also one of the first with a simple latch arrangement that actually works well and is beefy enough to not worry too much about bending or breaking the connector by accident. Far better than HDMI, which can partially pull out with no warning, and no screws like DVI or VGA to deal with. Having said that, I feel just about the opposite about the mini-displayport connector; I'd much rather have an HDMI . But the miniDP does save space.... My CentOS 7 Dell Precision M6500 laptop (ATI Firepro 7820 graphics with the stock CentOS ATI driver, not the Catalyst/fglrx one) is driving three 1920x1200 displays (two dell 24 inch 16:10 and the laptop's built-in 17.1 inch) very well indeed. When I take the laptop to the conference room, I can plug in the projector after I've already logged in through the laptop's built-in (not on the dock) DisplayPort, and the desktop is automatically extended. I also like the new behavior that gives a choice as to whether the workspaces apply to the second and third monitors; this way, I can switch workspaces in the conference room while displaying a presentation and what is displayed on the projector doesn't change, without me having to manually set 'Always on visible workspace' manually. I carry an inexpensive active DisplayPort to HDMI/DVI/VGA triple adapter with me, and it really does 'just work' when it's plugged in. Now, part of that smooth and convenient operation is of course due to the ATI driver; I had previously had an nVidia Quadro FX3800M in this laptop, but those cards are problematic in the M6500 (google for 'M6500 black screen' and see). The noveau driver didn't allow use of the DisplayPort at all, and I had to use the proprietary nVidia driver from ELrepo and an underclocking tweak to get DisplayPort to work. The FirePro 7820M isn't very expensive on eBay these days, and I purchased a NoS unit and resolved my issues. So your mileage may vary, depending upon which graphics card you have and which driver you use.

I'm waiting to see if my current monitor actually dies. It's an Asus 1920x1200 monitor that I like rather a lot, but it occasionally acts a bit flaky when coming back out of sleep mode. (The screen fills with a white brick-like pattern, but when I turn the monitor off and back on again it works perfectly once again. It has gone weeks between episodes of this, and it's done it two or three times a day -- very inconsistent.) If this monitor actually does die, I'm thinking that I'll replace it with a 2560x1440 monitor, but the built-in Intel video controller on my motherboard apparently supports that resolution only on the Displayport connector; the DVI port maxes out at 1920x1200. I guess I can purchase the higher resolution monitor without fear if I need it, and I sincerely appreciate your recommendation for a video card too! -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

I haven't tried with the fglrx driver; it seems to be a bit of a problem child on C7 at the moment. For that matter, the nVidia proprietary driver is a bit of a problem child if you have any encrypted partitions like I do. As I don't have anything with higher resolution than 1920x1200 with which to test, I can't comment on that, sorry.
