I bought new monitor Samsung SyncMaster S24B420, connected via VGA (which have 1920x1200 60Hz native resolution) And I have problem that in Windwos 8 I can set only 1600x1200 as maximal resolution.

I tried install official monitor drivers, but I think that problem is in ATI driver because when I show "List All Modes" in "Advanced setting" for screen resolution I see that maximal is 1600x1200

But I can't find ATI driver, because they don't release W8 drivers they recommend use Microsft native driver "ATI Mobility Radeon HD 3400 Series (Microsoft Corporation - WDDM v1.1)"

My HW Lenovo R500 type 2732-32G

Thanks for help

What exactly is your question? The generic drivers are your only choice with the graphic you have. – Ramhound Jan 2 '13 at 15:20
Questing is how I can set 1920x1200 resolution .. Graphic card can set 2048 x 1536 resolution for VGA output – Kurtas Jan 2 '13 at 15:26
Have you tried installing the legacy AMD drivers for Win8? – Lennart Jan 2 '13 at 15:28
@Lennart Yes I tried it, there is packed same generic driver for W8 "Display Driver (WDDM 1.1)" – Kurtas Jan 2 '13 at 15:31
True, but it includes the Catalyst Control Center with which you can add HD resolutions. – Lennart Jan 2 '13 at 15:32

Try the Thinkvantage System Update It have found problem drivers for me in the past.

I tried it but it only offering download "Lenovo Power Management Driver" and "ThinkVantage Active Protection System" ... nothing what I need :( – Kurtas Jan 2 '13 at 17:03

I had struggled with this same resolution problem in Windows 7 and my solution may work for you if your system has similar ports.

Both my monitor, FHD2400, and video card, ATI FireGL v3600, supported 1920x1200 but that option did not show on the selection menu. The monitor had been detected by Windows as a generic and not recognized by the model. I had the monitor connected to the card with a VGA connection thru a KVM with a VGA to DVI connector at the video card.

I switched to a DVI cable directly from the card to the monitor and upon reboot windows recognized the monitor and automatically selected the 1920x1200 resolution.
