HANNS-G 1080p Custom Resolution For Intel GMA Graphics Cards

If you have an Intel GMA chipset and are not getting the native resolution out of your monitor, you may have already come across the various utilities (namely MonInfo and DTD Calculator) which allow you to calculate then set a custom resolution. It works, except in certain cases then you have to play with the settings… One which was my new Hanns-G HH251 full HD monitor. Luckily I found this article which put me on the right track. Basically, it only works when you set the horizontal resolution to 1919, but it still displays 1920 pixels across selectable in Windows after the registry hack and reboot in DTD Monitor! Strange, but true!

Here are the settings which DO WORK:-

Modeline: 138.5 Mhz, 1919 “H Active”, 1968 “H Start Sync”, 2000 “H End Sync”, 2080 “H End Blank”, 1080 “V Active”, 1083 “V Start Sync”, 1088 “V End Sync”, 1111 “V End Blank”, Non-Interlaced, +HSync -VSync

DTD: 1A 36 7F A1 70 38 1F 40 31 20 35 00 1F 31 21 00 00 1A

Here are the settings which SHOULD BUT DON’T WORK (reported by the monitor EDID / MonInfo):-

Modeline: 138.5 Mhz, 1920 “H Active”, 1968 “H Start Sync”, 2000 “H End Sync”, 2080 “H End Blank”, 1080 “V Active”, 1083 “V Start Sync”, 1088 “V End Sync”, 1111 “V End Blank”, Non-Interlaced, +HSync -VSync

DTD: 1A 36 80 A0 70 38 1F 40 30 20 35 00 1F 31 21 00 00 1B

One interesting point is that 1920×1200 resolution works fully plug-and-play with no messing about, when I tried it on the same machine with a different (16:10 / 1200p) monitor (namely the Fujitsu SL3260W). The only problem with that one was it lacked options to turn off zoom and preserve aspect ratio, so I returned it and went for a 1080p to be sure that nothing gets stretched when watching movies or playing XBOX via VGA cable (I have an old one). It’s not nice to play car racing games with egg shaped wheels!

But after receiving and using the Hanns-G and discovering full aspect ratio options and fully featured OSD, I would strongly recommend that or better the 28 inch 16:10 Hanns-G model so that you get the best of both worlds (1200p for PC and 1080p for games and movies) without stretching. Avoid Fujitsu monitors like the plague, they have a crappy OSD and pixel fault policy (even when they state fault class 1 in the data sheet!).

  1. not quite on topic Tony but I have a Hannspree LCD TV. It has a Samsung panel and is good as any of the more well known marques.

  2. Thank you very much. Worked a treat on Windows 7 with Intel 915. Just replaced all instances of DTD_5 in the registry with your DTD, rebooted and selected 1919×1080. Before that I’d spent at least 2 hours pulling my hair out. I couldn’t understand why the DTD extracted from the monitor wouldn’t work.
