I've had an Asus 26", 1920x1200 for about 4 years. If the new ones are equally good, you'll like it. As for the audio... there are instructions to get sound over DP, but you don't have to use it. You can just use the "normal" path... audio chip-to-monitor/speakers via audio cable.
I used to use the NVS 290 with DMS-59. I had 4 or 5 failures due to the DMS-59 cable. (Seem lots of wires crammed into space and not well connected/secured.) Was glad to switch over to the 295 with DP thinking they would be more robust and reliable. That has been the case... no connector failures. But a few year later and messing with the NVS 300's DMS-59, looks like the cables are now built better. Should be OK now.
Yeah. I know. I would use my existent set up until the 4k mons come down to commodity pricing level (like the 52" plasma TV I've gotten 7+ years ago at >$3000, now can be bought at $500?)... We have seen questions on buying monitor this, video card that... we just need to realize that the monitors, video cards, video cables, computer itself... all kind of go hand in hand for upgrade considerations. (And furniture, room space, power circuits, A/C too). I have blown a few circuit breakers already...
Yep. I am back to square one since I had returned my monitors. Now I am looking to get 4 27" monitors that has displayport...
I think bigger is better. I can see charts much much better. Now I am thinking if there is a way for me to get a projector and project it on the wall. That way, I need no monitors....just empty white wall. I can trade from the wall )
While there are advantages to having a monitor with displayport, I'd say DVI is definitely good enough, I don't see a disadvantage to using DVI only. You can adapt to DVI from displayport, so no reason to spend the extra for a monitor with a new enough design to integrate displayport. The active adapters are only $15 on monoprice.com.
