This thread has some excellent information in it. Thank you for the OP and the many replies.


I recently convinced my workplace to order a DELL U3011 as a new monitor. I love the monitor but it does have annoying hiccups such as no rotation with the stand and no rotating OSD.

The rotation was fixed by using an Ergotron LX wall mount. This mount is the most amazing monitor 'accessory' I have ever seen. After the crazy installation the monitor moves anywhere I need for sitting/standing depending on my mood. Highly recommended.

The monitor is just stupid big. Retarded big.





Unfortunately, that's not where the problems ended.

I use a Macbook Pro Retina at work. The DELL is unable to connect via the HDMI due to needing Dual Link DVI. A simple Mini Display Port -> Display port is all I would ever need right? Wrong.

Using a simple Display Port cable to an LCD other than an Apple Cinema on an Mac results in the Mac outputting YpBpr instead of RGB. The Apple refuses to see the monitor as anything but a TV.

Why does this matter? The color space is very much off. Even with a wide gamut colorimeter I am unable to correct the green tint on the DELL.

I have now ordered an Apple MiniDisplayPort -> Dual Link DVI adapter, but don't have high hopes.


Thanks Apple.

I have a late-2011 Air connected via a MDP-to-DP cable to a Dell U2410 right now and it's in RGB. So it must be a macbook pro thing, or a cable thing. The cable I used is this one:

Well, there's the part where it's limited to 25Hz or 41Hz. Would be cool for displaying enormous-res slide shows or movies, though!

It needs four links of DVI aggregated as a single display. You're only going to get that with a Radeon with at least two DP outputs and setting them up as an Eyefinity group. You'd be SOL with Nvidia gear.

You can actually run it on just a single-link DVI cable if you really wanted to. Sure, you'd be limited to 13Hz, but it'd work! Similarly, a normal dual-link DVI port/cable would get you 25Hz. I'm not sure why you wouldn't be able to get quad-link with Nvidia gear: use a normal dual-link port and an active DP->dual-link adapter. With a maximum of 41Hz, it's not like you'd be using it for games or anything that wasn't near static, anyhow.

It supposedly works with a dual link DVI and a single link DVI with slightly reduced refresh rate. Both current ATI and nvidia cards only have a dual DVI port and a single DVI port, and the rest is allocated for DP.

Twice the DPI of the 27" screens probably only would work with images, nothing text based or interactive.

Nvidia doesn't do display aggregation on 4x1 setups. It would treat each half of the screen as a separate dual-link monitor, or, with 4xsingle link, as a 3x1 with an "accessory quarter".

Be that as it may (and I don't have an Nvidia card to check), the original T220 will certainly run at least at 20Hz off an Nvidia card, and the T221 comes with a converter box which uses the GeForce 6 as a specific example of cards that work with it.

It's a pointless argument, though, since I don't think anyone's gonna jump on a 41Hz monitor here.

I really like that it's 16x10. I really like that it's 24 inch. I really like that it's an IPS panel. The USB3 ports are a plus, too. $30 off is a nice incentive, but not the selling point.

I'm upgrading from a 22" 1650x1080 TN panel that I mostly use for web/email and gaming (560 Ti), but more and more of my gaming is now done on the 42" TV across the room.

Very odd. I wonder if it truly is down to the firmware in the monitor? It looks like the 3011 is a newer monitor than the 2410.

I read of many issues with the adapter due to firmware less than 1.0.3. It's hard to justify a $100 adapter that isn't guaranteed to work.

Most TVs are pretty terrible monitors. Even 5' away (which isn't very far) you're going to have a pretty terrible effective pixel density by comparison, text is almost always hard to read, and you usually are going to have substantially more latency/input lag compared to a fast monitor.

Can you do it? Sure. Should you do it? Probably not. What exactly attracted you to the concept, anyhow?

Jabor posted:

Let's say you put yourself back far enough to make a decent effective pixel density. And you got a display that actually has a decent (two frames or less) lagtime, and if that's in Game Mode or whatever, that it doesn't have some sort of nasty flicker the whole time.

You may not be able to defeat the overscan. (And using drivers to work around it leaves you with bad stretching effects and an effective resolution that will make a lot of games barf.)

You may be dealing with a display in CIE rec.709 color space, or something even less appropriate for a computer display. Most computers expect sRGB, and most computer monitors provide sRGB.

I've even seen some TVs which force 4:2:2 compression on every single signal that gets passed to them. Say hello to murky anything-red-or-blue.

And that's not even including the crazy things that TVs do to not-computer signals. Digital scalers that leave banding in not-precisely-a-factor-of-720-wide inputs, completely rejecting 240p input, etc, which makes it useless for old consoles like the Playstation 2. Maybe you won't run into that driving it with JUST a PC, but you may as well check at the same time.

If you really REALLY want a TV as a computer display, then make sure you don't have to deal with any of that crap BEFORE you buy it. If you already have the TV yeah give it a shot, but be ready to make friends with disappointment.

Most flatscreens still come with overscan. This is partly because of "that's how it's always been done" and partly because channels and program editors still play fast and loose with things at the edges of the viewable area. Not allowing the user to turn off overscan, at least at sub-native resolutions or on 'old' signal types (SD broadcast, composite, s-video), isn't unheard of.

But even if you don't have to deal with overscan, or your video card will still do the scaling for you instead of the TV (not always a guarantee), all the other problems I listed.

The fact that I could double it up as an actual TV when I have friends around instead of huddling around a monitor was the big motivator.

It sounds like the big issues are:

  • Display latency.
  • Text fidelity.
  • Colour space issues.
  • Overscan.
  • Doing other really dodgy stuff that can't be disabled.

I'm not concerned about pixel density (If it's the same angular size and same resolution, then the effective pixel density is the same, right?), but there's definitely stuff there I need to consider.

I guess I should haul off to a store and see if they'll let me gently caress around with some of their displays to see how they'll look.

Knowledge is born from Curiosity.
I've never encountered a HDTV where you can't turn off overscan. I've been able to do it with numerous Panasonic, Samsung, Sharp, and LG HDTV's. Even the the 7 year old offbrand HDTV (Olevia) I still have around for some reason can do it. It's not always named something sensible but you can most likely do it somewhere in the settings.

As has been said, you really don't want to be working around overscan via graphics card settings as that degrades picture quality and can cause issues with games.

If you're just planning on using it for media output, like running TV shows or movies or something, then fine, have at. You may still run into the issues listed, but most of them are basically immaterial for video play-back. Really, you just don't want to be trying to game on one, or--even worse--trying to read text on them. They're just not designed for it, and you will be frustrated attempting to do either of these things.

As for size, 5' isn't far enough. At 5' away, a 55" TV (~48" wide) has an angular size of about 43.6deg. A 24" monitor at 32" away gives an angular size of 35.3deg, or about 25% smaller. But yeah, if you put it far enough away (7' or so), you'll be back to a similar effective pixel density. It's more an issue of TVs not really playing nice with PC input that's the problem, anyhow.

Their entry level LCDs (which mine is) are basically equivalently priced to Sony/Samsung/LG where I am. It helps I got a killer deal on my one because it was last years model - made it the cheapest 1080p set of that size with three HDMI inputs.

Also while I know they make some great high end plasmas they also sell a bunch of garbage entry level ones with 1024x768 panels.

I have a Samsung PN50B560, which is admittedly 3 years old, but even after figuring out how to disable overscan and turning the sharpness mods down/off, there's still a very noticeable difference in how it displays a lot of things vice my laptop's screen. Mind you, it doesn't actually impact the movie watching and whatnot that I do with it, but text always either looks like it's still being sharpened unnecessarily, or has a bit of a ghost/double-image to it. My desktop background (a night sky with stars) looks like poo poo because of it, too.

That's probably a color issue. Most TVs do not do uncompressed color, instead natively doing only 4:2:0 color. That's the type of sampling done in most MPEG2/h.264 video, which is what most TVs show all the time, so it makes sense. But while that works fine for high-color images with natural transitions, it makes computer imagery look like a lovely JPEG all the time, so most hard edges and text are fuzzy and indistinct.

They are probably 768p. In many cases you can disable overscan on these displays if you feed then a native 1366x768 signal, but there is no menu option to do it for non-native resolutions.

I have never seen a 1080p TV without the option to turn overscan off. In fact, my Sony LCD doesn't allow you to turn overscan on when feeding it a native 1080p signal.
