Have you looked at the Asus PG27AQ screen? It might be what you're looking for, but it's not out just yet. This may be one of those rare times where it's actually worth waiting a short time.

[QUOTE=TheMawn;397140]I have always liked the idea of multiple monitors though I have only occasionally had the chance to enjoy it.[/QUOTE]

I have been using multiple monitors for at least 15 years, starting at 1280 by 1024 times 2. I'm now at 1920 by 1080 times 3. It can get addictive; I truly feel handicapped in front of only one screen (even with 36 virtual desktops).

A couple of years ago I had planned on building my "dream workstation" with 3 4K displays. Unfortunately my laptop (my main workstation) died unexpectedly, so I had to quickly build a new (tower) machine from locally available components (thus the HD monitors). Might work out for the best; let the 4K offerings improve while dropping in price.... :smile:

This one? [url]http://rog.asus.com/393642015/gaming-monitors/ces-2015-rog-swift-pg27aq-27-inch-4k-lcd-with-gsync/[/url]

I have in fact been looking at it. Not surprisingly, the 144hz 1440p one is the ASUS one also, mentioned on that page. Also not surprisingly is that I've come to the same conclusions they have about which is better for which type of game.

By "competitive" I meant a game in which you're competing real-time against other people (not that I play at a competitive level) like a Real-Time Strategy game. The faster frame rate seems appealing in that kind of scenario.

The fact that they're both 27 inches makes having one of each seem like less of a hassle.

And I thought I was doing well having a new 1920 by 1280 screen (27 inch). I also have a 1280 by 1024(19 inch). These serve me fine currently.

[QUOTE=petrw1;397085]My rough math tells me it will take about 20 Million GhzDays to TF all remaining exponents above 30,000,000 to 70 Bits[/QUOTE]

If GIMPS were to dedicate its entire resources to this goal, it could be attained in a mere six months. We're presently producing roughly 39 million GHz-days/year across all work types.

All exponents below [B][COLOR="Blue"]54,357,769[/COLOR][/B] have been tested at least once.

The estimated "completion date" for the classic 79.3M range has been hovering around Jan-Feb 2018 for almost 5 months. Going back to 2013 it has been in the same range +- 2.5 months.

LOL... I was just thinking, all it really takes is for one grandfathered exponent, like one of them in the 54M range, to hold things up for decades. :)

Under the rules as I think I understand, there's a bit of grace involved if the exponent is close to completion. One of those for instance is something like 96-97% complete but only progressing 0.1% every few days. Each time it checks in, which to it's credit it does regularly, it sets the estimated completion as just a couple days away but that's patently false. :) If we imagine that it progressed at a glacial 0.01% every week, but kept checking in, it wouldn't be expired and it might take another few years to finish.

In this extreme fictional example, if it still has 3.2% to go and only moves at 0.01% per week, it would take an additional 6+ years, and it wouldn't expire because the grace rules think it's close enough that it won't expire it.

In reality it progresses more like 0.1 - 0.2% every week so it'll "only" be another 4-8 months give or take, not the estimated 4 days the client reports in each time. Those other 2 <54M grandfathered assignments are just 63-64% done and are moving similarly slow so those might take years to finish still.

Good news is that there are only so many grandfathered assignments left, and if you look at the <56M list, that's all of the grandfathered first time checks...just those 9. There are another 7 grandfathered DC assignments. One is in the 34M range and the rest are 35M-38M so they're not impeding any imminent milestone completions.

A real example...please don't poach just because I noted this....
 
I've been monitoring 4 of them in 55M range (belonging to "dannytoearth") for a few months now.
They are all now 67-68% and making regular daily progress.
They were at 53% at the start of the year.
They are progressing at just over 0.2% per day.

So even though the page

says 110 days to go it will more likely be (100 - 68) / 0.2 = 160 days....mid - late August

BUT AGAIN I believe they will finish.

Those 2 at 63-64% will expire mid May 2015 unless progress is made: [URL="http://mersenneforum.org/showpost.php?p=396149&postcount=1715"]post #1715[/URL]

Not counting the grace period when very close to finished, we will be done with all grandfathered exponent in Dec 2015 at the latest: [URL="http://mersenneforum.org/showpost.php?p=396196&postcount=1724"]post #1724[/URL]

Well, one of these four has been poached. dannytoearth now has 55107499 assigned as a DC.

Wasn't me this time at least. :smile:

I still have those 3 in the 54M range already tested, ready to check in as a DC as soon as they check in the for the first time. Spoiler alert, none of them were prime.
