Haswell HD4400/4600 DP - 4k?

本帖最後由 luke123 於 2016-6-9 22:22 編輯

Hi

Has any C Hing used the DisplayPort output of Haswell in-built graphics HD4400 or HD 4600 to drive a 40" (or bigger) 4k monitor? Is there any noticeable lagging (eg, in moving the mouse pointer around, refreshing a stock price data chart)?

Thanks in advance!

HD4400/4600 @ 4k最多只能30Hz
一定lag

Thanks!

What about inexpensive display cards with DP 1.2 and 1 GB GDDR3 RAM? Do you think they will output 4k at 60 Hz with little lag?

Thanks again.

Thanks.

How about something requiring refreshing at short intervals, say, 500 ms? Like many share price charts displayed real-time on a 4k screen?

Thanks again.

Do you think Iris Pro would perform significantly better in terms of lag?

Thanks.

呢個你擔心CPU問題多過IGP問題
