Dell U2713h Vs U2713hm

Just noticed the 1.07 billion colours 6ms vs 16.7m 8ms...is it noticeable?


Just found a review of the differences but not sure I am allowed to post the link.
The U2713H uses a new type of backlight comprised of green and blue LEDs (GB-LED), allowing it to cover 103% of the NTSC color gamuit, 99% of Adobe RGB, and more than 100% of the sRGB space. This new backlight combined with 10-bit color support (achieved with an 8-bit + FRC panel) gives the U2713H a color palette of 1.07 billion, compared to 16.7 million of the W-LED equipped U2713HM.

Yes, that's one of the most significant differences. The 2713H also has a number of other features tailored towards colour accuracy. This is because the screen is aimed at those who need accurate colours (photographers, graphic designers etc.) ahead of other features. What would your main use of this screen be?

I have a 2713HM; it displays the BIOS screen on bootup. Overall, I am very pleased with this screen - I would definitely recommend one if you're looking for a 27" 1440p screen.
 
Thanks for your replies, reading them now. Was concerned about the 'faults ' posted on this forum last night.
Any additional info welcomed....
 
You have these major faults known about the HM, if you can spot them:

Bad backlight bleed
Cross hatching on the AG
Image retention

Those are the main issues with them, and the newer models are supposed to be much better in this regard. If you're willing to do a few exchanges, I think you'd quite like it, once you get a good model!

You are more likely to get a good panel with a H model, however unless you make use of the wide gamut, you probably won't like how it over saturates the colours. And, if you try to emulate sRGB mode, you will find it looks washed out in comparison to the HM at standard mode (It goes slightly above sRGB, so it looks more vibrant without blowing out your retinas. I like it a lot. It has the exact same vibrant colours as a glossy panel, just without the reflections. Sounds like a winner to me!)

I think mines a July 2012 batch from recollection, which I think is the first run and I have experienced no problems during normal use.

It appears to be a lottery as to whether you get a good one or more likely that some people are more picky than others.:)

Indeed, glad to hear yours is ok.
When did you buy yours?
 
You wont notice any difference between 8 bit and 10 bit in real world usage because 10 bit colour is only used very rarely in very specialist applications anyway. 6 bit + FRC however can be noticably worse than 8 bit depending on the quality of the implementation on the monitor. Basically you dont need more than true 8 bit colour for everyday usage. Also the 10 bit screens seem to have more input lag so this may be a concern if you are gaming on it.

I can't say I agree with that. There is of course 10-bit content and if you have the required components you can make use of it. So for some people it might be advantageous. Of course it is quite rare and also expensive but saying there's no content isn't true.

Also as long as you're comparing the same panel technologies and the FRC is implemented well you won't notice any practical difference between a 6-bit+FRC panel and an 8-bit panel. Saying they are noticeably worse is misleading. There's plenty of very good 6-bit-+FRC IPS panels out there which are very good

You are being pedantic.... In real world usage 10bit colour is not used except in some extremely rare scenarios, which if the poster was an advanced user that actually used these, he would not have made this thread asking if 10 bit was necessary in the first place....

6 bit + FRC is actually something which may be noticably worse at times eg. colour banding and noticable dithering etc.... Although yes on modern IPS panels they are pretty good at 6 bit + FRC so you would probably never notice. Obviously it is more important to have true 8 bit vs 6 bit + FRC than it is to have 10 bit for everyday use...

Thanks for being pedantic but I am not really sure what was acheived or if it was helpful? .... However you are right... I could have worded my post better.... I edited it for you ok?

ok an interesting reply. Careful with the sarcasm please

I wasn't being pedantic, i was correcting the mis-information about there being no 10-bit content available that you'd posted so that the OP and others had the correct information. I was also trying to make the point about 6-bit+FRC vs 8-bit as that's a common misonception and you seemed to be following the same "logic" as loads of other people who start talking about it. Your edited version makes more sense now, so thanks.
 
I appologise for the sarcasm lol.

It does seem that although 6 bit + FRC is a lot better than it was previously, there are still some minor image quality issues which mean it is still better to have true 8 bit. 10 bit however not really necessary unless you have specialist equipment.

I was very close to picking you up on your comments about 6-bit +FRC vs. 8-bit as the difference is really quite slight for most users and modern fine dithering algorithms. The edit was a good one.
 
Yes you are probably right, I was going on my experience which was from a couple of years ago of 6bit + FRC vs 8 bit but it seems that recent IPS monitors are better for this now.
