[TFT Central] Samsung CF791 Ultra-wide with 100Hz VA Panel and FreeSync - Page 6

post #51 of 159
Any idea what the pixel pitch is going to be? Anything much bigger than 0.27mm and I can see the individual pixels too easily.

Still, might beat what we currently have in this department. Just because it doesn't have DP 1.3or 1.4 doesn't mean it won't be a good monitor. Hell, the amount of pixels to push at 100hz, let alone 165hz at that resolution will take quite a bit of gpu power.

We have more than enough GPU power now with the GTX 1080 and upcoming VEGA GPUs for even 4K 60 FPS.

I understand why someone would spend 1000$ on this monitor, but personally I wouldn't. I buy monitors to use them for long periods of time without feeling the need to upgrade, I had mine with the XL2730Z that I've had for a long time without feeling there's anything to upgrade to, a 100Hz monitor would be a downgrade, higher resolution and aspect ratio doesn't really cut it if it comes with compromises, if I must upgrade it had to be 144Hz at the very least.

Otherwise I wont feel like paying 1000$ for a sidegrade, it's time to move forward! I mean, I'm not even asking OLED here, and I should be asking OLED.

Yes, VAs are worse than IPS panels in this regard, this monitor doesn't really seem to be a compromise free upgrade at all, not for us people with already working 144Hz 1440p TNs or IPS monitors.
Ultrawide is definitely an upgrade over 16:9. If all you want is 144Hz, you are going to be waiting awhile for VA panels at that frequency and the resolution of this ultrawide or 4k (Edit: And is there anything coming out sooner than 2017 for 144Hz IPS in 1440p ultrawide or 4k?). I am also not sold on the refresh rate being higher than the FPS you are pushing making that much of a difference. That is what FreeSync and GSync are for.

With a little trigonometry knowledge you can figure it out yourself. I'll save you the trouble though: ~0.22mm.

If you wanted to do trigonometry (and I don't get the number you listed when I do), then the listed 34" is not the most accurate number to use as the actual screen size may be different (e.g. 33.8"). Furthermore, the spacing of pixels and subpixels differs vertically and horizontally, so there's more error introduced when using the 34" dimension to guess at the pixel pitch. The manufacturer's listing would undoubtedly be more accurate.

At the nominal 34", the width across is ~29.64", or ~752.7mm. 752.7/3440 ~= 0.22. What number do you get? Also, a fraction of an inch makes next to no difference (at 33.8" it's 0.2175mm).

That's about my dream panel right there. Ultrawide, curved, VA panel. I just need gsync as I'm a nvidia user.

In order for the long side to be 29.64", the short side would have to be 16.66". That's a 16:9 monitor, not a 21:9 monitor (and 3440/1440 is not exactly 21:9 anyway). So, the difference even 0.2" makes is actually going to be different than what you calculated, too. You're right, I could get a guesstimate of what the actual value is.

You're right, my mistake; I inadvertently calculated it for 16:9. Still, at the correct ratio of 21:9 it's only ~0.23mm.

Love VA, wish they were more popular so more work could have been done on the tech.

Agree with you, I love my VA panel as well. My only wish is that it would be higher resolution.

It seems that's Samsung's duty. Rolling out monitors and TV's with VA panels. Even Samsung's budget 4K TV is using a VA panel in their 2016 series.
